  • Slide 11
  • Chemical Interactions of Ground Water and Surface Water: Ground-water chemistry and surface-water chemistry cannot be dealt with separately where surface and subsurface flow systems interact. The movement of water between ground water and surface water provides a major pathway for chemical transfer between terrestrial and aquatic systems. This transfer of chemicals affects the supply of carbon, oxygen, nutrients such as nitrogen and phosphorus, and other chemical constituents that enhance biogeochemical processes on both sides of the interface. This transfer can ultimately affect the biological and chemical characteristics of aquatic systems downstream (Winter, 2008).

  • Slide 13
  • Coal Mines Coal is a valuable resource used in energy production Produces $500,000,000 in revenue in the state of New Mexico every year. Mined in New Mexico and worldwide Can have serious environmental consequences
  • Slide 14
  • Coal mines as Non-point source Coal mines become non-point source pollutors if they are not operated, constructed or reclaimed adequately ( http://www.water.ky.gov/sw/nps/). Precipitation causes loose sediment to wash into streams with harmful substances naturally found with coal. http://www.brentnebeker.org/RaySnow.JPG
  • Slide 15
  • Coal mines as point source Regulated under Coal Mine Point Source category of CWA Applies to active mines Standards set for settable solids, heavy metal deposition and pH. So which is it ? No real consensus. In CWA part 434 as point source, yet treated as a non- point source also.
  • Slide 16
  • Coal mines as sources of pollution Coal mines affect water quality in two ways 1. Active mines contribute to changes in pH in waterways. Erosion Heavy metals 2. Abandoned mines can cause acid mine drainage and toxicity in surface and ground water. Erosion Heavy metals
  • Slide 17
  • Active coal mines In New Mexico: Coal mining companies are required to develop reclamation plans before beginning mining. Coal mines must pay into abandoned mine regulation fund Established by Surface Control and Reclamation Act of 1977. Activities regulated by New Mexico Energy, Minerals, and Natural Resources Department, Mining and Minerals Division. emnrd.state.nm.us
  • Slide 18
  • New Mexico Energy, Minerals, and Natural Resources Department Coal Mine Regulation Program (CMRP) Involved in regulation, inspection, enforcement. Developed in 1980s under Surface Mine Control and Regulation Act (1977). CMRP monitors active mines Mines get Notice of Violation if they violate any rules Can appeal or fix problem
  • Slide 19
  • Abandoned Coal Mines No regulations when many abandoned mines were developed. Abandoned Mine Land Program Partnership of state agency and Department of Interiors Office of Surface Mining Funded by Abandoned Mine Restoration Fund Abandoned mine must qualify under one 0f three criteria http://www.emnrd.state.nm.us/MMD/MMDNotes/fullsize/Story310_DillonCanyon_2006.JPG
  • Slide 20
  • Environmental Damage Erosion Increased turbidity Increased light filtration Carries heavy metals Acid Mine Drainage
  • Slide 21
  • Acid Mine drainage Coal occurs with rocks containing sulfide, commonly pyrite Sulfide exposed to air and water during mining operations Coal gob, or piles of waste rock, contain sulfide. Oxidizes in presence of air and water Creates sulfuric acid Sulfuric acid transports heavy metals to ground and surface water Poisons plant and animal life creating dead streams
  • Slide 22
  • Acid Mine Drainage. From www.agf.gov.bc.ca/.../images/acid_mine_fig1.jpg
  • Slide 23
  • Case study: Sugarite gob restoration Located near Raton, NM Coal mining operations from 1912 to 1942 The Problem: Extensive gob piles left behind Gob piles had high saline levels, were moderately acidic, contained heavy metals and were actively eroding; in some places, channels cut 20 feet deep into gob piles. Eroding into Chicorica Creek, causing excessive sedimentation and toxicity; Chicorica Creek is used for trout fishing and downstream irrigation. In some cases, the gob piles were in contact with the creek. Chicorica Creek located only 300 feet from the mine entrance Coal mine waste impacted 22 acres of land
  • Slide 24
  • Sugarite State Park Remediation efforts began when Sugarite Canyon became a State Park in 1983 New Mexico Abandoned Mine Land Bureau, under direction of Office of Surface Mining, began remediation Driving factors: Environmental Water quality Safety http://k41.pbase.com/g6/17/586817/2/86145046.yXCSBvc7.jpg
  • Slide 25
  • The goal Reduce acidic runoff Reduce erosion Reduce turbidity and sedimentation into Chicorica Creek
  • Slide 26
  • The Remediation Plan Main problem was erosion Straw bale terraces built Compost and fertilizer added to gob clay to make hospitable for plants Seedlings planted To reduce acidic runoff Lime incorporated into acidic gob to increase pH From Sugarite Canyon Reclamation Project Report
  • Slide 27
  • What to do about coal mine pollution? Monitoring active coal mines for pollutant release can help decrease pollution. Reclaiming abandoned coal mines Must find a balance between need for coal for energy production and health of the environment. http://ecotechdaily.com/wp-content/uploads/2008/06/coal_pile_620.jpg

  • Slide 29
  • Largest nonpoint source of pollution due to human land use: AGRICULTURE! Most abundant contaminant = soil Includes manure, chemical fertilizers and pesticides Fertilizers used on land add nitrogen and phosphorus thatwash back into the water supply Pesticides used to control insects wash into water supply
  • Slide 30
  • How do pollutants get into the water system? Usually washed in due to water itself Rainfall (natural) Irrigation or diversion of water (human-induced) Can come from point or nonpoint sources Surface runoff (irrigation or rainfall) flows downhill until it meets a barrier- such as a body of water Leaching(precipitation or irrigation) enters soil and can contaminate water table

  • Best Management Practices (under NPSMP) Structural practices: diversions, temporary sediment basins, animal waste lagoons, fencing, terraces, and other constructed means of reducing pollution. Nonstructural practices: resource management techniques- timing and rate of fertilizer or pesticide application, conservation tillage methods, livestock grazing rotation, riparian planting, and upland revegetation.
  • Slide 38
  • Structural BMPs used in southwest -includes Middle Rio Grande Drain inlet inserts Extended detention basins Biofilters Media filters Infiltration Largest contributer of bacteria load: anthropogenic including pets and livestock
  • Slide 39
  • NM Pesticide Control Act Rules for proper application and disposal of pesticide being used: Only to be applied by a licensed certified applicator and pesticide to be used must be registered for use in New Mexico Should be disposed of in permitted waste disposal sites Any apparatus that has pesticide in it should be cleaned at waste site or in evaporation ponds so it will not get into water No pesticide waste shall be disposed of in sewer or storm drain But pesticides can still be washed into water system by rain or irrigation runoff
  • Slide 40
  • Classes of Pesticides Insecticides Used to control insect (and other animal control agents are similar) Persist and remain in environment for a long period of time-also remain toxic longer Can enter water system and accumulate in invertebrates, fish, birds, mammals, humans

  • Americas Urban Landscape Since World War II Americans have invested much of their newfound wealth in Suburbia with 80% of everything in the U.S. being built in the last fifty years. The Growth of suburbs after WWII was facilitated by the availability of FHA loans, economic growth, the newly designed highway system along with the increase in personal car ownership, and the general ideology of Americans to live away from the troubles of City Life. Since the beginning of the 21st Century, Americans have not stopped this development outward into Suburbia, but serious questions, especially here in New Mexico concerning water, about the sustainability of this expansion has been increasing.
  • Slide 70
  • Albuquerques Urban Landscape: Rio Rancho Rio Rancho is the third largest and fastest growing city in New Mexico As of the 2000 census the city population was 51,765 people, and has risen to 75,978 residents as of the 2007 census estimate. The city has a total area of 73.5 square miles.
  • Slide 71
  • Water in New Mexico Pollution and poorly planned development has endangered New Mexicos limited water supplies. New Mexicos water problems are the product of unwise patterns and policies, lack of conservation, over pumping and excessive river water withdrawal, inter and intra-basin transfers, development, and pollution. Rio Rancho receives its water supply primarily from the Santa Fe Group Aquifer, not from the Rio Grande River.
  • Slide 72
  • Water in New Mexico Cont. Its estimated that about 20 billion acre feet of water exists in ground water deposits in New Mexico, only about one quarter of that is considered drinkable and most of the rest is not readily accessible or cost- effective to recover. Ground water aquifers, river, and streams are hydrologically-connected, such that surface water rejuvenates ground water supplies through leaching, while ground water often flows into streams in the form of springs.
  • Slide 73
  • Water Policy in New Mexico The rapid growth of communities, like Rio Rancho, has consequences for New Mexicos limited water supply. Water policy has simply not kept up with modern needs. As the population of NM and the greater SW region grew, surface water became fully appropriated and disputes emerged between states to determine how much water each state was able to use from each surface water source. As a result, interstate stream compacts emerged, dividing up water rights and setting use limits. In total, New Mexicos water use is guided by eight compacts: the Colorado River Compact, the Upper colorado River Compact, the Rio Grande Compact, the Pecos River Compact, the Canadian Compact, the La Plata Compact, the Animas La Plata Project Compact, and Costilla Creek Compact.
  • Slide 74
  • From: Aletta Belin, Consuelo Bokum and Frank Titus, Taking Charge of Our Water Destiny: A Water Management Policy Guide for New Mexico in the 21st Century, 2002. A fully appropriated water system in NM means that all surface water is appropriated. So, in dry years all junior water rights users may not be able to access water, if that water is required by senior water rights holders. However, full appropriation quickly becomes overappropriation when junior users rely on ground water, which is some cases comes from unmetered and unregulated domestic wells. Drawing on this ground water means that less water flows at surface levels, and is therefore unavailable for senior water rights holders. Moreover, depletion of ground water and the long-term impacts are difficult to detect immediately, prevent, or remedy once identified.
  • Slide 75
  • Water Policy in NM Cont. This situation leaves the state in a difficult position. To date, only minimal steps have been taken by the Office of the State Engineer to address the problem of impairment of water rights to senior users, because doing so would mean cutting off water to cities. Water demands continue to increase, more water is withdrawn from an already delicate and overworked system than is being introduced, and NM will continue to risk violating interstate stream compacts. This just furthers the need to adopt policies and solutions that will balance New Mexicos water quality and quantity.
  • Slide 76
  • Pollution in NM Water Polluted water affects quantity because it removes needed water from an already stressed supply. Unfortunately, both surface and ground water are highly susceptible to pollution, and once contaminated, these water sources are difficult to treat. The result is a combination of artificially-introduced and naturally-occurring contaminants that make their way into NMs ground and surface water supplies.
  • Slide 77
  • Salinity in NM High salinity is also major problem in parts of NM. The main sources of the salinity are: agricultural runoff, industrial practices that require ultra pure water and release large volumes of saline water, waste water treatment, household water softeners, and natural sources from rock and soil. This pollution problem becomes a water scarcity issue when salinity is above 500 parts per million, which the point at which water is neither drinkable or usable for irrigation.
  • Slide 78
  • Current Water Solutions Rio Rancho Water Conservations Ordinances Rio Ranchos comprehensive water reuse strategy
  • Slide 79
  • Rio Rancho Water Conservation Ordinance Ordinance No. 19 Enactment No. 03-022 Adopted by the City on June 25, 2003. This Ordinance shall address water use recommendations to assist in reducing the overall per capita water use in the City. Water conservation measures are encouraged for all privately owned and government properties.
  • Slide 80
  • Rio Rancho Water Conservation Ordinance The Water Conservation Ordinance is comprised of three main components: Prohibited Acts for water waste and fugitive water Time of Day watering restrictions Water by Request
  • Slide 81
  • Rio Ranchos Comprehensive Water Reuse Strategy From Rio Ranchos Water Quality Report Spring 2008 This strategy involves the use of high-quality reclaimed water to supplement the Citys limited groundwater supply and to minimize the declines of aquifer water levels. The aquifer recharge demonstration will proceed in two phases: During Phase 1: potable water from the Citys distribution system will be injected over a 4-week period at a rate of 1 to 2 million gallons per day (mgd) to evaluate aquifer response. Injection flow rates, water quality, and water level trends will be observed in five monitoring wells and an injection well constructed for the demonstration test. During Phase 2: a high quality reclaimed water source will be produced using advanced water treatment techniques. The compatibility of the final recharge water source with native groundwater will be assessed using water quality data from the Phase 1 demonstration.
  • Slide 82
  • Possible Water Solutions A clean, reliable supply of water is vital to the economy, ecology, and quality of life for the state of New Mexico. There are potential policy solutions that the state can adopt that will help protect this vital resource.
  • Slide 83
  • Rio Rancho Looks into the Future.... In the Water Quality Report 2008, Rio Rancho explored New Water Resources Recently a brackish aquifer was discovered 3,800-feet beneath the Rio Puerco basin. What does it mean for our water future? Treated water could be sold to the City of Rio Rancho and its water customers. However, the final costs are not yet known. Sandoval County is undertaking a study for domestic consumption using desalinization and new technologies to remove other contaminants.
  • Slide 84
  • Steps towards a clean, reliable water supply...According to Me Conserving Our Water Resources: Not overusing but using just enough. Adopting An Equilibrium Management Strategy: Balancing out New Mexicos rivers and groundwater water quantity Maintaining Water Quality: Reducing and Preventing pollution
  • Slide 85
  • A recap: Contamination can come from numerous sources including: coal mining, agriculture, runoff, anthropogenic and natural sources. Surface water and ground water are interconnected systems. So changes in one affect the other. A decrease in water quality is equivalent to a decrease in water quantity. Policy is designed to manage water quantity and quality. We all need clean water!!!
