WATER SAMPLES M-86 (MAJOR CONSTITUENTS), T-87 (TRACE

CONSTITUENTS), AND P-5 (PRECIPITATION SNOWMELT)

By Victor J. Janzer

ABSTRACT

The U.S. Geological Survey began an interlaboratory testing program of Standard Reference Water Samples in 1962. Program objectives have been to provide a means for participating analytical laboratories to: (1) Identify analytical problems, (2) ascertain the accuracy and precision of common water analyses and analytical methods, and (3) obtain reference samples for continuing quality-assurance testing. Participation in this continuing quality-assurance program is mandatory for all domestic laboratories providing water-analysis data for Survey use and storage in the WATSTORE data storage system, if appropriate Standard Reference Water Samples are available.

The program was expanded in October 1982 to include international laboratories. This report presents analytical data submitted by the 53 laboratories in other countries that analyzed the reference samples distributed in October 1983. Statistical evaluation of the data and performance ratings achieved by the laboratories for each determination are given in nine tables. Comparisons of the most probable values for the constituents determined by both international and domestic laboratories are also presented.

INTRODUCTION

The U.S. Geological Survey began an interlaboratory testing program of standard reference water samples in 1962. Principal purposes of the program have been to provide a means for participating domestic analytical laboratories to: (1) Identify analytical problems, (2) ascertain the accuracy and precision of the analytical methods for determining the various constituents and physical properties of water and (3) obtain reference samples for continuing quality-assurance testing. Twenty-three Geological Survey laboratories participated in the 1962 effort to determine six constituents in a single standard reference water sample (SRWS) containing major constituents. Now, more than 120 domestic laboratories participate in the program that uses as many as 8 SRWS types; major constituents, trace constituents, nutrients, herbicides, insecticides, water- sediment mixture for trace metals, precipitation snowmelt, and priority pollutants.

Participation in this continuing quality-assurance program is mandatory for all domestic laboratories providing water-analysis data for Survey use and storage in the WATSTORE data-storage system, if appropriate SRWS are available. Major constituent, trace constituent, and nutrient SRWS are prepared and distributed to domestic laboratories twice each year. One or more of the other SRWS types may also be included.

The program was expanded in October 1982 to include a number of international laboratories. Samples have been distributed to the laboratories in other countries only once a year, during October of 1982 and 1983. This report summarizes analytical data submitted by the 53 international laboratories that analyzed the reference samples distributed in October 1983. Statistical evaluation of the data and performance ratings achieved by the laboratories for each determination are given in nine tables. Comparison of the most probable values for constituents determined by both international and domestic laboratories are also presented in three additional tables. The domestic data were reported previously (3anzer and Latal, 1984).

PURPOSE AND PLAN

As a means of providing an independent, objective evaluation of the water-quality data published by the U.S. Geological Survey, SRWS are prepared and distributed for analysis at regular intervals. SRWS M-86 (major constituents), T-87 (trace constituents), and P-5 (precipitation snowmelt) were distributed to 100 domestic laboratories in October 1983. In addition, SRWS were sent to 68 international laboratories that indicated their willingness to analyze these reference samples. All samples are not analyzed by all laboratories nor do all laboratories participate in each round of analyses.

Each laboratory was requested to indicate the analytical methods used and to perform at least those determinations that it makes routinely. Laboratories participating in this study are identified only by confidential code numbers.

PREPARATION OF SAMPLES

SRWS M-86 (major constituents), and T-87 (trace constituents) were each prepared from a surface water collected from the same source. Samples were filtered through a 5- ym (micrometer) nominal size prefilter and a 0.45-ym membrane filter into a 1325-L (liter) polyethylene drum. Thymol, about 1.25 mg/L (milligrams per liter), was added to SRWS M-86 and T-87, to reduce growth of fungus.

Some trace constituents (vanadium and fluoride) were added to SRWS M-86. No constituent additions were made to SRWS T-87 but it was acidified to a pH of about 1.5 with nitric acid. Each sample was mixed overnight with a motor-driven, Teflon!/-coated stirrer, filtered through a 0.45-ym membrane filter, and passed through a flow-through 254-nm ultraviolet sterilizer and bottled, under ultraviolet radiation, in 1-L autoclaved polypropylene bottles or dry-heat sterilized Teflon bottles.

SRWS P-5 (precipitation snowmelt) was prepared by melting snow collected in several 200-L polyethylene drums. After melting, the sample was filtered through a 0.45- ym membrane filter. No additions of any kind were made to this sample. After mixing overnight, the sample was again filtered through a 0.45-ym filter, sterilized by passage through the flow-through ultraviolet sterilizer and bottled in 1-L autoclaved polypropylene bottles or dry-heat sterilized Teflon bottles under ultraviolet radiation.

LABORATORY PERFORMANCE AND REPORTED VALUES

To facilitate interlaboratory performance comparisons, ratings based on the analyses of each SRWS are included in this report as tables 2-4 (all tables are at back of report; the abbreviations and symbols used in the tables are defined in table 1). Laboratory performance for each constituent is rated on an arbitrary scale of 0 to 4 based on the number of "standard deviations" from the mean determined for each constituent as indicated below:

4 (Excellent) 0.00 to 0.50 standard deviations3 (Good) 0.51 to 1.00 standard deviations2 (Satisfactory) 1.01 to 1.50 standard deviations1 (Questionable) 1.51 to 2.00 standard deviations0 (Poor) Greater than 2.00 standard deviations

When the analyses for a constituent are extremely precise, these ratings may be overly severe and should be considered only as indicators of relative performance. Averages of the constituent ratings for each SRWS are given for each laboratory in tables 2-4 of overall laboratory performance.

The values reported for all constituents determined in each SRWS are listed in tables 5, 7, and 9. Each value has been rounded off, when necessary, to conform to U.S. Geological Survey policy on reporting analytical data. Laboratories were requested to indicate the general method used for each determination. When this information was provided, method identifications have been included with the analytical data. Statistical information by method for each determination are listed in tables 6, 8, and 10. Summary comparisons of other-country and domestic laboratory analyses of SRWS M-86, T-87, and P-5 are presented in tables 11-13. Mean concentrations for most constituents determined by both laboratory groups show good agreement.

Participants are encouraged to submit comments or suggestions concerning this program to:

STATISTICAL EVALUATION

A statistical evaluation of the data was made to estimate the most probable value (MPV) for each of the constituents. Values reported as "less than" were considered "not determined", and were not used in the computation of the means, standard deviations, and so forth. These data are indicated as "ignored" in the computer listings.

The mean, standard deviation, and confidence limits about the mean are usually reported to one more significant figure than the reported value. Statistical information is tabulated for each method used by three or more laboratories to determine a specific constituent. Tables giving the mean and standard deviation determined by that method, and the number of laboratories which used it, follow the analytical data tables for each SRWS.

Outliers in each data set are identified and rejected based on the T values (Grubbs 1 test) described and tabulated in the American Society for Testing and Materials (1981) Recommended Practice E-178 (1980). If the computed T value is greater than the tabulated value for the number of samples and the significance level selected, the outlier is rejected. T is computed by:

Xn -X

where T = T value for probable outlier,

Xn = concentration of probable outlier,

X = arithmetic mean (average) of all values, and

S = standard deviation of all values.

After rejection of the outliers, the data remaining for each constituent were used to calculate the means, standard deviations and percent deviation from the mean. Values identified as outliers were omitted when calculating the means and standard deviations for each determination listed by "method". The total range for each constituent included the outliers. Confidence intervals about the mean were also calculated. These define the range within which the true value is expected to occur with a confidence level of 95 percent.
