EPA's Office of Water helps to ensure that the latest water pollution science and best available control technologies support our program goals to keep water safe and clean.

Analytical Methods and Laboratories
Learn about the EPA-approved analytical methods and laboratories that water systems must use when analyzing samples to meet federal monitoring requirements or to demonstrate compliance with federal water regulations.

Applications & Databases
Find valuable information on a host of different databases, maps, models, and tools. Includes popular applications such as, the Clean Watershed Needs Survey (CWNS), STORET,WATERS, AQUATOX, and Surf Your Watershed.

Climate Change
Offers comprehensive, accessible, and meaningful climate change information for all parts of society – communities, individuals, business, states and localities, and governments.

Contaminants of Emerging Concern
Pharmaceuticals and personal care products are detectable at low levels in surface water.  EPA has made it a priority to determine impacts on human health and the ecosystem and to regulate accordingly. 

Drinking Water
Provides information on drinking water health advisories, other human health risk assessments, and science support for drinking water regulatory determinations.

Monitoring & Assessment
Water quality data are used to characterize waters, identify trends and emerging problems, determine the efficacy of pollution control programs, direct pollution control efforts, and respond to emergencies such as floods and spills.  View data or find out how you can help.

Research and Risk Assessment
Learn about the National Water Program Research Strategy, Semi-Annual Newsletter and ongoing or completed research on Drinking Water Quality and Ambient Water Quality.

Surface Water Standards & Guidance
Provides information on Water Quality Criteria and Water Quality Standards, fish and shellfish advisories, fish tissue studies and requirements for cooling water intake structures.  

Wastewater Technology
Provides information on wastewater technology including a host of publications and reports and links dedicated to biosolids and industry effluent guidelines.
