Presentation Outline • 1. What is Source Water and Source Water Protection? • 2. What are the benefits associated with source water protection? • 3. What are potential threats to sources of drinking water? • 4. What are tools & techniques to protect drinking water sources? • 5. How can your community protect sources of drinking water?
What is SOURCE WATER? Why is it so important? Source Water = Drinking Water • Drinking water sources: • Surface water (rivers, streams, lakes and reservoirs) • Ground water (aquifers and springs) • Public and Private wells • Vibrant community economies and public health depend on good local water quality
Stream Precipitation Evapotranspiration Pumping Well Surface Runoff Recharge Lake Lake Plant Uptake Aquifer Ground Water / Surface Water Interaction
What is SOURCE WATER PROTECTION? Protect drinking water sources: provide clean, safe water that minimizes treatment expenses, protects public health, and sustains communities. • Many partners: public water systems, community leaders, land-use decision-makers, agricultural & forestry leaders, and the public. • Voluntary actions and requirements at local, state, and federal levels that together can keep contaminants from entering sources of drinking water. • State source water programs - based on each state’s water resources and drinking water priorities.
Safe Drinking Water Act Multiple-Barrier Approach MONITORING & COMPLIANCE SOURCE WATER PROTECTION reduce contaminant threats TREATMENT COMMUNITY INVOLVEMENT
Potential Pathways of Contamination • Surface Water • Urban/rural runoff (e.g., stormwater, livestock operations, farm fields, lawns) • Ground water infiltration • Direct discharge to water bodies (animal feces, boating, dumping) • Ground Water • Infiltration (e.g., pesticide spills, fertilizer from row crops, animal production, improperly located or maintained septic systems) • Injection of contaminants • Naturally occurring substances (e.g., arsenic, radon)
What Information is Available to Protect Sources of Drinking Water? • Source water protection areas: geographic areas around drinking water sources, used to identify and help protect from potential sources of contamination • Potential contaminants/sources: States identified most prevalent, most threatening • http://water.epa.gov/drink/local/ • Source Water Protection (SWP) Plans: Some localities have used this information to develop & implement SWP plans

State/Local Actions to Protect Sources of Drinking Water • Update source water assessments, refine information about potential contaminants/sources • Identify priority contaminants and sources • Provide information for inspection and enforcement programs • Develop voluntary partnerships to protect water quality: State Conservationists (NRCS/USDA), conservation districts, watershed groups, recreation groups
Actions that Protect Sources of Drinking Water • Identify land use management and other measures that may be needed • Preserve land uses that protect water supply • Regular septic system care • Agricultural best conservation practices, e.g. fencing livestock out of streams & providing an alternate water source, fertilizer and manure management, conservation buffers, conservation tillage & crop rotation, drainage water management, efficient irrigation, integrated pest management • Forestry best management practices to protect forests that preserve water quality
Costs of Contamination Direct Costs Indirect Costs Health Costs Lost Productivity Reduced Revenue for Businesses that Depend on Clean Water: Tourism & Recreation, Food Processing Lost Economic Development Opportunities Lost Consumer Confidence Loss of Property Value and Tax Revenue • Treatment and Remediation • Water Supply Replacement • Public Information Campaigns

The Costs of Prevention • Vary based on the prevention measures selected • Responding to contamination can be much more costly than prevention • Remsen, Iowa spent over $700K to purchase farmland for conservation to protect its drinking water from high nitrate levels, vs. over $2M projected cost for new nitrate treatment system • " More than 117 million Americans (over 1/3 of the total US population) get some or all of their drinking water from waters that are not clearly protected right now. Some communities have found that every dollar spent on source water protection saves about $8 to $27 in water treatment costs.“ Geographic Information Systems Analysis of the Surface Drinking Water Provided by Intermittent, Ephemeral and Headwater Streams in the U.S. Performed by U.S. EPA July, 2009,http://water.epa.gov/lawsregs/guidance/wetlands/surface_drinking_water_index.cfm
