INTRODUCTION

Atmospheric deposition occurs when airborne constituents are transferred to the earth’s surface. There are many sources of emissions to the atmosphere, and many pathways where constituents in the atmosphere are transported and deposited to the landscape. Atmospheric deposition can occur as wet deposition (via precipitation - in rain, snow, clouds, and fog) and as dry deposition (via dry fallout - including particles, aerosols, and gases). Airborne emissions can be transported for short or long distances (e.g., up to hundreds of miles) before being deposited to the landscape. Thus individual emissions sources can affect broad regions, and even relatively undisturbed areas can be blanketed with inputs of pollutants via atmospheric deposition. Acidic atmospheric deposition, commonly referred to as acid rain, is the transfer of acids and acid-forming substances from air to the earth’s surface (Driscoll et al. 2001). Emissions of gases to the atmosphere from multiple sources can react with water in the atmosphere to form acidic compounds, which in turn can be deposited to the landscape by wet and dry deposition. Acid producing gases are released to the atmosphere through both natural processes (e.g., emissions from volcanoes, lightning, fires, and decaying vegetation) and from anthropogenic processes (e.g., largely attributed to the combustion of fossil fuels). There are numerous airborne gases that produce acids when they react with water in the atmosphere. For example, carbon dioxide reacts with water in the atmosphere to form carbonic acid. Even under natural background conditions, precipitation is typically acidic due to the ubiquitous presence of carbonic acid in the atmosphere, with pH generally cited as being around 5.6. Oxides of nitrogen and sulfur, which are emitted to the atmosphere primarily by fossil fuel combustion, are criteria air pollutants regulated by the US Environmental Protection Agency. These gases react with water in the atmosphere to produce nitric and sulfuric acids, which are considered to be the primary precursors of acid rain. Precipitation is considered to be problematic when pH values drop below about 5.0. The northeastern USA receives precipitation with mean pH that ranges from about 4.3 in Pennsylvania and New York to 4.8 in Maine and the upper Midwest (Kahl et al. 2004). Because acids and other chemical constituents tend to accumulate in the atmosphere during dry periods between storms, the most acidic rain typically falls at the beginning of a storm, and as the rain continues, acids are washed out of the atmosphere. Precipitation plays an important role in biogeochemical cycling by cleansing the atmosphere of many pollutants and delivering dissolved substances to aquatic and terrestrial ecosystems of the landscape. Atmospheric deposition is among the most ubiquitous non-point sources of chemical inputs to ecosystems. It can affect water quality and human health and impact aquatic, terrestrial, cultural, and material resources. Long-term effects of atmospheric deposition in the northeastern USA (including Pennsylvania) were recently summarized by Driscoll et al. (2001, 2003) and Kahl et al. (2004). The studies highlight the need to quantify the spatial and temporal variation of inputs to the landscape by atmospheric deposition in order to understand potential and realized effects. Atmospheric deposition is of particular interest to scientists, land managers and policy makers in Pennsylvania. Rates of acidic deposition (e.g., nitrogen, sulfur, hydrogen ion) have been elevated for decades (USEPA 2009) and are among the highest in the nation (see Figures 3 &4). Though emissions from within Pennsylvania are significant, atmospheric pollution is also attributed to the state’s geographic setting downwind of major stationary emissions sources in the heavily industrialized midwestern USA (USEPA 2009). Although significant progress has been made in reducing acid rain in Pennsylvania and across the Northeast and Mid-Atlantic

6

regions (see Tables 12 and 13), additional reductions in sulfur dioxide and nitrogen oxides emissions are likely necessary to protect acid sensitive aquatic and terrestrial ecosystems and cultural and material resources in the Commonwealth (Driscoll et al. 2001). Climatic variability and change may also change the magnitude and patterns of atmospheric deposition in new ways. Because of the importance of precipitation in providing water and its dissolved substances to the landscape, an atmospheric deposition monitoring network was established in Pennsylvania in 1981 under a Cooperative Agreement between The Pennsylvania State University and The Pennsylvania Department of Environmental Resources, currently the Pennsylvania Department of Environmental Protection. Today, work continues to determine the magnitude and distribution of wet atmospheric deposition in Pennsylvania and to consider their potential environmental impacts. The monitoring effort provides an important long term record of precipitation chemistry across Pennsylvania. The detailed study of the spatial and temporal chemistry of wet deposition (precipitation) and dry deposition serves many functions: (1) it provides basic baseline data needed for quantifying status and trends of atmospheric deposition; (2) it provides basic data needed for quantifying how deposition is related to the frequency of precipitation events and variability of climate; (3) it provides data needed for evaluating possible impacts of pollutants on aquatic and terrestrial ecosystems, cultural and material resources, and human health; (4) it provides for comparisons of both beneficial and detrimental substances associated with atmospheric deposition; and (5) it provides quantitative means of evaluating the effectiveness of present and future air pollution control legislation. This report represents a summary of precipitation chemistry and wet deposition data collected at a network of 17 atmospheric deposition monitoring sites in Pennsylvania in 2007. Precipitation was sampled from each site weekly. Samples were analyzed for ions that are typically associated with acidity (pH, sulfate, nitrate, ammonium), base actions (calcium, magnesium, sodium, potassium), and salinity (chloride and specific conductance). NETWORK DESIGN AND OPERATION Monitoring Site Locations Seventeen atmospheric deposition-monitoring sites were in operation in Pennsylvania during 2007 (Figure 1, with details of the locations shown in Table 1). Support for observation and measurement at 11 of these sites was provided by the Pennsylvania Department of Environmental Protection, Bureau of Air Quality Control. These 11 sites and include: Presque Isle, Goddard, CrookedCreek, Laurel Hill, Allegheny Portage, Hills Creek, Little Pine, Little Buffalo, Millersville, Slocum, and Valley Forge. Support for another 6 sites was provided by other agencies, including: the U.S. Forest Service (Kane, Milford), the Pennsylvania Agricultural Experiment Station (Leading Ridge), the National Oceanic and Atmospheric Administration (Penn State), the US Geological Survey (Young Woman’s Creek), and the US Environmental Protection Agency (Arendtsville). These latter 6 sites plus the Millersville site all participate in, and report data to, the National Atmospheric Deposition Program’s National Trends Network.

Consistency with National Network To ensure comparability and consistency of data across Pennsylvania and the nation, we operate all of the sites in the Pennsylvania network according to the same protocols of the National Trends Network (NADP/NTN), online at http://nadp.sws.uiuc.edu. Site and operator protocols are given by NADP 2009 and Dossett and Bowersox 1999. Given the vast heterogeneity of physiography, terrain, climate, and land use across Pennsylvania, the sparse number of sampling sites in the national network in 2007 are not sufficient to characterize the spatial and temporal variability of wet atmospheric deposition, and are greatly enhanced by the supplemental observations provided at the monitoring sites of the Pennsylvania network. Field Instrumentation To measure precipitation chemistry, each site is equipped with an Aerochem Metrics wet/dry precipitation collector. This instrument consists of a two-container system with a movable lid designed to expose a wet container and cover a dry container during periods of precipitation, and vice versa. A sensor mounted on the instrument reacts electrically to the onset of precipitation causing the lid to move thereby exposing the wet-side container. Heaters mounted below the sensor serve to both melt snow and ice as well as evaporate moisture from the sensing element. This design ensures that the wet container is exposed only during periods of precipitation, and this is used for our analyses of wet deposition and precipitation chemistry. The wet container is rigorously pre-cleaned (by the analytical labs described below) and is replaced weekly. To measure precipitation volume, each site is instrumented with several recording and non-recording precipitation gages. Each Belfort recording rain gage was equipped with a timer/chart recorder keyed to the sampling interval of one week. The times of opening and closing of the wet/dry sampler were determined from an event recorder mounted on the recording rain gage. A standard non-recording rain gage was used to determine the total amount of precipitation. All of the monitoring sites in the Pennsylvania Network meet NADP/NTN standards for site selection and installation, and were instrumented with equipment selected for use in the national network (NADP 2009). Field Analyses Precipitation samples were collected following standard operating procedures established by the NADP/NTN (Dosett and Bowersox 1999) to ensure compatibility of data. Field personnel collect samples from each monitoring site weekly, on Tuesday mornings (or as near to that as possible). The "wet" sample containers were shipped to the laboratory each week regardless of whether precipitation occurred. Back in the preparation lab, operators weigh the collection bucket to determine the “field” sample volume, and measure the “field” pH and conductivity of the sample, and transfer the remaining sample from the collection bucket to a 1000 mL polyethylene bottle for shipping to the analytical lab. Samples are shipped overnight or taken directly to the water quality lab of Penn State Institutes of Energy & the Environment (for PA-only sites) or to the Central Analytical Lab of the Illinois State Water Survey (for NADP/NTN sites). Precautions were taken to preclude changes in or contamination of precipitation samples during collection, transport, and storage prior to analysis. Analyses were performed as soon as possible after receipt of the samples.

Laboratory Analyses Upon receipt at the water quality lab, samples were assigned a number that is traceable to a specific sampling period and site. Following immediate measurement of volume, pH, and specific conductance (if sufficient volume was present), each sample was filtered. Precipitation samples that were grossly contaminated were discarded. For samples arriving with a twig, leaf, pine needle, beetle, bumblebee, etc., the contaminant was removed by filtration and the sample processed like any other precipitation sample. At the time of sample check-in, comments were placed in the site record to indicate the visual appearance and the presence of odor of each sample. Precipitation samples were analyzed for the following parameters provided a sufficient volume was present: pH (H+), sulfate (SO4

2-), nitrate (NO3-), ammonium (NH4

+), chloride (CL-), calcium (Ca2+), magnesium (Mg2+), potassium (K+), sodium (Na+), and specific conductance. In the event that insufficient volume was present for complete analysis, the priority on analyses was as listed. Specific analytical techniques and laboratory equipment used for the PA network (not NADP/NTN) sites are listed in below (Table 2).

Quality Assurance Quality Control Protocols The quality control (QC) and quality assurance (QA) policies for atmospheric deposition monitoring that have been followed throughout this project were designed to provide maximum credibility of the data, including documented accuracy, precision, and completeness. Major components of this QA plan include sound QC programs addressing field operations, laboratory analyses, and data management. The QA/QC programs discussed below apply to Pennsylvania

network sites supported by The Pennsylvania Department of Environmental Protection. A separate QA/QC program is maintained by the NADP for all precipitation chemistry data from NADP/NTN sites that are included in this report (online at http://nadp.wsw.uiuc.edu) Field Measurements: Precipitation samples were collected following procedures established under the NADP/NTN and discussed in detail in the NADP/NTN Site Operation Manual (Dossett and Bowersox 1999). Calibrations of the recording rain gages were conducted each fall and spring or whenever discrepancies exist for two consecutive weeks between the recording rain gage and the non-recording gage. Weekly comparison of precipitation volume from the Aerochem Metrics wet/dry collector and the non-recording rain gage were made to assure that the sensor was properly activating the precipitation sampler. Using the event recorder, the opening and closing of the roof on the precipitation sampler was compared each week with the recording rain gage chart to determine if the sample had been exposed to the atmosphere during rain free periods and to determine if the sampler was responding to precipitation. Any contamination in the sample or any field sampling problems noted on the field form by the site operator were entered into each site's permanent record. Information on site operations is used in screening precipitation chemistry data to eliminate contaminated samples. Analytical Laboratory: Quality assurance for the analytical measurements given in Table 2 is a multi-tiered program that includes bench level quality control, laboratory management quality assurance, and external quality assurance monitoring. The analytical laboratory is expected to achieve at least the detection limits in Table 3 with maximum allowable variance in accuracy of ±100 percent of the detection limit, of ±20 percent at ten times the detection limit, and ±10 percent at 100 times the detection limit. Analytical Instruments (see Table 2) are maintained and calibrated according to manufacturer specifications. Standard preparation and instrument calibrations are among the most critical procedures in laboratory quality control.

Table 3. Minimum lab detection limits. For QA of the preparation of stock standard solutions, the Lab Manager arranges for (1) independent laboratory confirmation of each standard and (2) compares the results of new standard solutions to those obtained with prior standards. In some cases, the lab may also obtain confirmation by an independent analytical procedure within the lab, such as is the case with nitrate standards that are used to calibrate both the automated colorimetric apparatus and the ion chromatograph. Procedure 1 is accomplished by the simultaneous measurement of stock solution standards and U.S. EPA mineral and nutrient standards.

Quality control exercised by the analyst is also an essential component of the overall program. Immediately following instrument calibration, one or more reference samples are analyzed to ensure that the system is functioning properly. Subsequently, at a frequency of no less than 1 sample in 10, the analyst inserts a reference material duplicate or single-point standard to verify correct operation. The observed values for these QC samples must not differ from the theoretical value by more than ±5% for all parameters, except nitrate and ammonium that must not differ by more than ±10% of the theoretical value. When an unacceptable value for the calibration QC sample is obtained, the instrument is re-calibrated and all samples that were analyzed after the last acceptable QC sample are re-analyzed. One sample per batch is also prepared and must be within the control limit that is ±5% of the relative standard deviation. An Ion Chromatography Resolution Test is also performed for each analytical run. Records of all QC data are maintained in a bound notebook at each workstation and periodically reviewed by the Lab Manager. Maintenance of current information on the characteristics (precision, bias, detection limit, etc.) of each analytical method was provided by a continuous quality assurance monitoring program operated by the Lab Manager and Project Supervisor. The program includes "blind" insertion into the normal sample flow of split samples, spiked samples, and standard reference solutions. "Blind audit samples" using simulated rain water provided by the National Atmospheric Deposition Program Coordination Office and the Central Analytical Lab of the Illinois State Water Survey are also periodically submitted to the lab, generally at a rate of one per month. In addition to the above QC program, cation/anion balance, conductance balance, and percent ion difference are calculated for each sample with complete chemical analyses. Samples with poor cation/anion balance (<0.85 or >1.15) are checked for possible cause and re-analyzed. An approximation of the conductance of each sample is calculated by adding together the equivalent conductance of each measured ion at infinite dilution. The calculated conductance is determined by multiplying the concentration of each ion by the appropriate factor. The percent conductance difference is calculated by dividing the difference between the calculated conductance and the measured conductance by the measured conductance. Samples are screened based on the conductance criterion of +10% or -40%. The larger negative percentage is based on the fact that calculated conductance is always less than measured conductance due to the presence of ions in precipitation that are not measured. External Audits: The water quality laboratory participates in an inter-laboratory comparison study sponsored by the National Water Research Institute of Canada at least once per year. This proficiency testing program allows comparison of lab performance, by analyzing “blind” samples of rain and other soft waters. (See Table 11 for results from 2007). Data Management: All analytical results and field measurements are entered into a computer database by the Lab Manager. The data are entered twice and automatically checked to assure correct entry. All of the data are manually verified against the original laboratory and field forms. All of the laboratory data are evaluated based on available QA/QC data using established procedures. The objective of the data verification process is to identify and correct, flag, or delete data of unacceptable quality. All data are rigorously validated to identify outliers and detect possible systematic errors in the measurement and analytical processes.

DATA REDUCTION Precipitation-Weighted Means Seasonal and annual precipitation-weighted mean concentrations discussed in this report were calculated according to the formula below, where the precipitation-weighted mean concentration, Cw , for a given ion was calculated from the n valid samples in the season or year under consideration. Individual sample concentrations, Ci, were weighted by the measured precipitation, Pi, from the standard non-recording rain gage, with values substituted from the recording gage or sample volume for those infrequent cases where the standard non-recording rain gage was out of service or where rain gage measurements were otherwise invalid. The quantity of precipitation measured by the rain gage is usually greater than that captured in the sample bucket. Non-recording rain gage amounts, rather than the actual sample volumes, were used in the calculation of precipitation-weighted means. This practice is based on the assumption that the chemistry of the sample captured in the bucket represents that which was missed.

n ∑ CiPi i = 1 Cw = ───── n ∑ Pi i = 1

Weekly, Seasonal, and Annual Wet Deposition Estimates Weekly measured wet deposition (kg/ha) of each ion was obtained by multiplying the product of the concentration data (mg/L) and precipitation depth (mm) by 0.01. Ionic concentrations for each weekly sampling period were converted to depositions and then summed over desired periods. Total annual and seasonal depositions were calculated by adding to the measured deposition an estimate of the amount of deposition that occurred during those precipitation events that were not analyzed. The estimate of unmeasured deposition was based on the amount of precipitation measured but not analyzed and the precipitation-weighted average concentration of each ion for their respective summary periods. Concentration and Deposition Maps Color-shaded raster maps depict the annual and seasonal precipitation-weighted mean estimates of ion concentrations and wet depositions for precipitation across Pennsylvania in 2007. The concentrations and depositions were estimated from data collected at the 11 Pennsylvania Network and six NADP/NTN monitoring sites within Pennsylvania (Figure 1) and 31 NADP/NTN monitoring sites located around the periphery of the state (Table 4). Estimates of concentration and deposition for each pixel in an 1820-column by 1365-row grid superimposed on Pennsylvania were obtained by applying the multi-quadric equation spatial interpolation algorithm (Harding, 1974) to the coordinates and chemistry data from the 42 monitoring sites. The resulting estimated grids were mapped by applying a color gradient to the range of values in each grid and overlaying the state boundaries and monitoring sites on the colorized grids.

The trend model incorporated precipitation chemistry data that was summarized into 6, bi-monthly seasons for each year during the 1983 through 2007 trend analysis period. Concentrations were summarized as precipitation-weighted means. Seasonal deposition values were calculated from the corresponding seasonal precipitation-weighted mean concentration and the total seasonal precipitation volume. The components of the model are as follows: Cys = b0 + bs + yby + e where, Cys = estimated concentration or deposition during season, s, and year, y. b0 = estimated intercept of the linear model. bs = estimated shift in concentration or deposition during season, s, relative to the latest season (i.e., Nov-Dec). y = date at the mid-point of the season, expressed as decimal years (e.g., the first season of 1994 would be 1994.0833). by = estimated long-term linear trend in concentration or deposition.

14

Inferences on the direction and significance of long-term trends in concentration or deposition were based on the estimated value of by and on the F-statistic associated with by. Units The standard units used in this report are mg/L (milligrams per liter) or µeq/L (micro-equivalents per liter) for concentrations and kg/ha (kilograms/hectare) for wet deposition amounts. Conversion factors appear in Tables 5 and 6. Table 5 presents factors for converting among various deposition units and for converting ion concentrations to deposition amounts, given precipitation measurements in cm (centimeters). Table 6 presents factors to convert mass per unit volume to micro-moles or micro-equivalents per unit volume for direct elemental comparisons.

Summary Periods For this report, the annual period (defined by the weekly sampling on Tuesdays) started on 1/2/2007 and ended on 12/31/2007. The growing season or warm period represents the period when precipitation was primarily as rain, and includes samples collected from April to October. The dormant season or cold period represents the period when precipitation was primarily as snow and includes samples collected from January – March and November-December. These periods are typically adjusted to accommodate the weekly-on-Tuesday collection period. In 2007, the warm period was defined specifically as: 4/3/2007-10/29/2007, and the cold period was defined specifically as1/2/2007-4/2/2007 and 10/30/2007-1/1/2008.

NETWORK PERFORMANCE IN 2007 Catch Efficiency The precipitation catch efficiency of the Aerochem Metrics precipitation sampler and the handling protocols of site operators were very good in 2007. On an annual basis, the amount of precipitation that arrived at the water quality lab (determined from the volume of precipitation in the wet-side bucket) as a ratio of the amount of precipitation measured in the standard non-recording rain gage varied from 0.77 at the Allegheny-Portage site in Cambria County to 0.98 at the Millersville NADP/NTN site in Lancaster county (Table 7). A ratio of 1.0 indicates that 100% of the precipitation was collected by the sampler and that no precipitation was lost in transit to the lab. The annual network mean catch efficiency ratio was 0.89 with 10 of 17 sites having a catch efficiency ratio of 0.90 or higher. Considering that the Aerochem Metrics sampler, because of its design and aerodynamics, is less efficient in catching precipitation than a standard non-recording rain gage, the annual ratios are indicative of very good network performance. Studies comparing the sampler to a standard rain gage have shown that the sampler underestimates total annual precipitation by 5% to 10% of the rain gage measurement. Discrepancies between measured precipitation and the sampler's volume are also influenced by equipment failure (especially the sensor) and electrical outages. The form of precipitation (rain versus snow) and site exposure also influence the catch efficiency of the Aerochem Metrics sampler. This is evident when comparing the ratios of the weekly bucket volumes to the standard non-recording rain gage amounts for warm and cold periods (Table 7). At most sites (all but one), the sampler was more efficient during the warm period when precipitation was dominated by rain than during the cold period when precipitation frequently occurred as snow or ice. The network mean ratio during the warm period was 0.93 compared to 0.85 during the cold period. The lower ratios during the cold period reflect the sensor’s sensitivity in detecting light, dry snow, as well as other problems associated with freezing condition, such as electrical failures. Site exposure also affects the collection efficiency of the sampler. Where the Aerochem Metrics sampler is exposed (in an open field or on a ridge), as it is at M. K. Goddard State Park in Mercer County and the Allegheny Portage National Historic Site in Cambria County it is subject to higher wind velocities (which lowers catch efficiency) than samplers located at more protected (shielded) sites, such as the Leading Ridge and Young Women’s Creek NADP/NTN sites. The Allegheny Portage site is also often subjected severe icing problems which can affect sampler performance.

Sampling Frequency The number of measurements in 2007 by site and parameter is given in Table 8. The maximum number of valid precipitation samples that could have been collected by the Pennsylvania Atmospheric Deposition Monitoring Network during 2007 was 884. Since 60 of these sampling periods were without precipitation, the maximum number of potential samples available for complete or partial analysis was 824. Of this number, 720 samples (87.4%) contained sufficient volume for complete analysis. Of the sampling periods with precipitation but no analyses, many involved precipitation amounts of 0.05 inch or less. Failure of the Aerochem Metrics sampler to detect and sample very low intensity snow or rainfall accounts for many of the samples that contain insufficient volume for analysis. Another primary reason for not analyzing a sample is contamination. Our QA/QC procedures require flagging of sites that have various forms of materials in them, most frequently bird droppings or vegetation. Infrequently, we have a situation where the sampler malfunctions and the wet container is exposed during dry periods, where a sample is flagged as potentially contaminated. Percentage of Annual Precipitation Analyzed Another means of evaluating network performance is to compare the percentage of annual precipitation that was analyzed with the total volume of measured precipitation at each site. This comparison is given in Table 9 for each precipitation quality parameter. On average in 2007, about 94% of the mean annual precipitation in Pennsylvania was analyzed for various chemical constituents (for example, with 5.1% not being analyzed for pH to 6.12% not being analyzed for chloride). There is a lot of variability around the mean, and the network-wide average is distorted, for example, by the approximately 15% of the annual precipitation that was lost at Slocum State Park, the nearly 10% lost at Young Woman’s Creek and at Kane. Sample contamination accounts for nearly all of the unanalyzed precipitation, though occasional power outages can also contribute. Quality Assurance with Cation-Anion Balances The distribution of precipitation samples having "flagged" cation/anion balances (ratios <0.85 or >1.15) among intervals of precipitation volume, specific conductance, and total ionic strength for all valid samples collected at the 17 atmospheric deposition monitoring sites in Pennsylvania in 2007 are shown in Tables 10. About 93% of the precipitation samples with complete analyses were within the specified cation/anion criterion. Of the 53 samples that were flagged, 19% (10 samples) of them were from low volume storms (<0.3 inch), while another 14% (6 samples) were from storms that fell into the 0.3 inch to 0.5 inch range. Collectively, this group of 16 low-volume samples represented approximately 0.6% of the total volume of precipitation measured in Pennsylvania in 2007 (Table 10). Another 28% of the "flagged" samples were from storms ranging in size from 0.5 inch to 1.0 inch. This group of 18 samples represented another 1.7% of the total volume of precipitation measured in the state in 2007. Overall, the analyses of samples from 93.5% of the precipitation collected in the state met the cation/anion criterion. It should be noted that failure to meet the cation/anion criterion does not in itself mean that the analytical results for these samples are in error. The list of cations and anions that are measured represents the major ions found in precipitation. However, other ions, such as phosphorous, may be present, and if present would affect the ionic strength and subsequently the cation/anion balance. Furthermore, samples with low ionic strength and low specific conductance are more likely to be flagged than higher ionic strength samples.

Quality Assurance with Inter-laboratory Comparison Samples The water quality laboratory at Penn State Institutes of Energy & the Environment participates in an inter-laboratory comparison study sponsored by the National Water Research Institute of Canada at least once per year. Below are results for various constituents of water samples, conducted on 10 different rain and soft water samples chosen for the interlab comparison in 2007 (Table 11). Overall, the Penn State water lab compared favorably with other labs participating in the inter-laboratory comparison proficiency testing program. These audits were conducted by the National Water Research Institute in Ontario, Canada. For each “blind” sample, the “expected value” was the mean concentration of all the labs participating in the comparison minus the results from those samples with coded or flagged results. Samples are flagged, if the reported results are greater than or less than two times the standard deviation of the reported results from all participating labs.

PRECIPITATION CHEMISTRY AND WET DEPOSITION 2007 The wet atmospheric deposition monitoring network was established in Pennsylvania in 1981 to determine the status and trends of acidic and nutrient elements in precipitation. Results from 2007 are summarized here. Included are data from 7 National Atmospheric Deposition Program/National Trends Network (NADP/NTN) sites in addition to the the 10 sites supported by The Pennsylvania Department of Environmental Protection (DEP), Bureau of Air Quality Control (BAQC). One of the NADP/NTN sites is also supported by the BAQC. Hydrogen Ion (H+ as pH) The hydrogen ion concentration (measured as pH) of precipitation in Pennsylvania has declined approximately 51% (39.4 µeq/L) over the last 25 years (Table 12), while hydrogen ion deposition rates have declined 46% (Table 13). The 2007 statewide mean annual pH was 4.42 (Table 14). The decline in “acid rain” has been attributed to reductions in sulfur dioxide and nitrogen oxides emissions and to a much lesser extent increasing base cation and ammonium concentrations in some regions of the state. Seasonal pH values in 2007 were very similar; the statewide mean growing season and dormant season pH was 4.36 and 4.49, respectively. Regional differences were also quite small (Table 14). Despite the decrease in acidity, precipitation in the Commonwealth is still more acidic than nearly all other regions of the United States, as illustrated from the NADP/NTN national network (Figure 2). Figure 2. Mean annual hydrogen ion concentration (as pH) in precipitation collected in the USA in 2007 by the National Atmospheric Deposition Program / National Trends Network.

Sulfate (SO42-)

The statewide mean annual sulfate concentration in 2007 was 2.20 mg/L, with growing season mean of 2.79 mg/L and dormant season mean of 1.71 mg/L (Table 15). Sulfate concentrations have decreased approximately 37% since 1983 (see Table 12). Despite the dramatic decreases, sulfate concentrations and wet sulfate deposition in Pennsylvania continue to be higher than in most regions in the United States (Figure 3). The state received approximately 24.7 kg/ha of wet sulfate deposition in 2007 (Table 15). Nitrate (NO3

-) The statewide mean annual nitrate concentration in 2007 was 1.42 mg/L, with growing season mean of 1.31 mg/L and dormant season mean of 1.51 mg/L (Table 16). Nitrate concentrations have decreased approximately 33% since 1983 (see Table 12). Despite the dramatic reductions, nitrate concentrations in precipitation and rates of wet nitrate deposition in Pennsylvania continue to be higher than in most regions in the United States (Figure 4). The state received approximately 15.85 kg/ha of wet nitrate deposition in 2007 (Table 16). Ammonium (NH4

+) The statewide mean annual ammonium concentration in 2007 was 0.35 mg/L, with growing season mean of 0.38 mg/L and dormant season mean of 0.31 mg/L (Table 17). Ammonium concentrations have decreased approximately 14% since 1983 (see Table 12). Rates of ammonium deposition in Pennsylvania are not as high as the heavily agricultural mid-west, but are nonetheless important (Figure 5). As rates of nitrate deposition have declined, ammonia deposition is becoming more important as a fraction of total atmospheric nitrogen deposition. The state received approximately 3.81 kg/ha of wet ammonia deposition in 2007 (Table 17). Base Cations (Ca2+, Mg2+, K+, Na+) Base cation (calcium, magnesium, sodium, and potassium) concentrations occur in precipitation at very low concentrations (Tables 18-21) with annual means ranging from around 0.15 mg/L for calcium to around 0.03 mg/L for magnesium. Calcium and magnesium concentrations have generally decreased the past 24 years where as sodium and potassium concentrations have increased (Table 12). These cations are important in that they are a source of acid neutralizing capacity in precipitation and are also essential plant nutrients. Wind blown soil particles and coastal sea sprays are important sources for these cations. Chloride (Cl-) Sea-salts can be an important source of chloride concentrations in south eastern Pennsylvania (Table 22), while coal combustion and the release of hydrochloric acids is an important source in western Pennsylvania. Mean annual chloride concentrations range from 0.09 mg/L to 0.44 mg/L across the state (Table 22) with the highest concentrations occurring at the Valley Forge site in Montgomery County. Chloride concentrations have exhibited mixed temporal patterns with some sites increasing slightly while others have decreased (Table 12). Conductance (Cl-) Conductivity gives a measure of total dissolved solids in precipitation, and is used to aid in our quality assurance program. Mean annual specific conductance ranged from 17-32 uS/cm across the state (Table 23), with a lot of variability over time (e.g. seasonally) and space (site to site).
