Protect Human Health
Strategic Objective
Overview
Sustaining the quality and supply of our water resources is essential to safeguarding human health. More than 300 million people living in the United States rely on the safety of tap water provided by public water systems that are subject to national drinking water standards. Over the next 4 years, EPA will help protect human health and make America’s water systems sustainable and secure by:
- Providing financial assistance for public water system infrastructure to protect and maintain drinking water quality;
- Strengthening compliance with drinking water standards;
- Continuing to protect sources of drinking water from contamination and ensuring reliable supplies of drinking water as water temperatures increase (including addressing the harmful effects of algal blooms);
- Developing new and revising existing drinking water standards to address known and emerging contaminants that endanger human health; and,
- Supporting states, tribes, and territories in their oversight of public water systems in implementing these standards, and supporting water systems directly through provision of guidance, training, and information.
While promoting sustainable management of drinking water infrastructure, we will provide needed oversight and technical assistance to states, tribes, and territories, so that their water systems comply with or exceed existing standards and are able to comply with new standards. We will also promote the construction of infrastructure that brings safe drinking water into the homes of small, rural, and disadvantaged communities and increase efforts to guard the nation's critical drinking water infrastructure.
In addition, EPA is actively working Agency-wide and with external partners and stakeholders to implement a multi-faceted drinking water strategy. With this approach, EPA seeks to: address chemicals and contaminants by group, as opposed to working on a chemical-by-chemical basis; foster the development of new drinking water treatment technologies; use the authority of multiple statutes in addressing drinking water contamination; and, encourage collaboration with states and tribes to share more complete data from monitoring at public water systems. To this end, the Agency is replacing the federal and state components of EPA’s Safe Drinking Water Information System (SDWIS) with a new system. SDWIS Prime is designed to assist regulatory agencies with their implementation of the public water system supervision (PWSS) program, as well as improve the efficiency of sharing drinking water data among states, tribes, and the Agency. This will allow for better targeting of federal and state funding and technical assistance resources, and improve data quality while increasing public access to drinking water data.
Science-based water quality criteria are essential to protect our public water systems, groundwater and surface water bodies, and recreational waters. These criteria are the foundation for state and tribal tools to safeguard human health such as public advisories for beaches, fish consumption, and drinking water. Over the next 4 years, we will expand that science to improve our understanding of emerging potential waterborne threats to human health, develop new criteria, and validate testing methods that provide quicker results and enable faster action on beach safety.
External Factors and Emerging Issues
EPA’s underground injection control (UIC) program provides a framework to ensure protection of underground sources of drinking water from endangerment related to the construction, operation, permitting, and closure of injection wells that place fluids underground for storage, disposal, enhanced recovery of oil and gas, or minerals recovery. Natural gas plays a key role in our clean energy future. Hydraulic fracturing is a key way to recover natural gas from sources. EPA will ensure proper oversight of hydraulic fracturing operations in cases where diesel fuel is used by implementing permitting guidance under SDWA's Class II UIC program for hydraulic fracturing. EPA is working with state and tribal organizations, along with other federal agencies, to develop and implement voluntary strategies for encouraging the use of alternatives to diesel in hydraulic fracturing and improving compliance with other Class II regulations, including possible risks from induced seismic events and the risk from radionuclides in disposal wells. EPA is also continuing to work with state, tribal, and industry representatives to make UIC Class II regulations and information more transparent and to implement best practices and promote coordination between UIC and oil and gas agencies.

EPA has made progress addressing the safety of our nation’s drinking water, with over 93 percent of the nation’s population served by community water systems (CWSs) receiving drinking water that meets all applicable health-based drinking water standards in FY 2014. The following four examples highlight how EPA is making progress toward its drinking water objective in collaboration with states, tribes and local utilities:
- Through the DWSRF, EPA helps ensure reliable delivery of safe water to people served by small water systems by funding infrastructure improvements, with 70 percent of assistance agreements going to drinking water systems serving fewer than 10,000 people. This funding supports EPA’s cross-agency strategy of making a visible difference in communities, especially in rural and disadvantaged areas.
- EPA is achieving its priority goal of working closely with states through capacity development and optimization programs to enhance small system sustainability, principally through optimization trainings and state-EPA workgroups and products. These activities improve the states’ capability to help small systems, including drinking water systems on tribal lands, address their technical, managerial, and financial needs.
- If adopted by states, EPA’s 2012 recreational water quality criteria recommendations[1] will protect the public from exposure to harmful levels of fecal pathogens.
- More than 2,000 public water systems participating in the Unregulated Contaminant Monitoring Rule[2] survey provided drinking water monitoring data for 30 unregulated contaminants; these data support decisions on whether to establish health-based standards to protect drinking water.
