Research Areas

Arsenic  Arsenic is an element found naturally in soil, in the bedrock that underlies the soil, in groundwater, and in ocean water. Human activities can release arsenic into the environment. Research has shown that arsenic can accumulate in solids found in drinking water distribution systems.

Contaminants  Today, our nation's drinking water supply is one of the cleanest in the world, in part because EPA has set standards for about 90 contaminants that can affect drinking water. Even so, microbes, chemicals, and pathogens are still a concern.

Corrosion  Corrosion is the degradation of metal. In water distribution pipelines, valves, and fixtures, it can cause the degradation of the quality of our drinking water. EPA’s research helps to control corrosion and reduce the release of metals into our drinking water distribution systems.

Distribution Systems Research  Throughout the world, millions of miles of water distribution pipeline provide drinking water for individual and industry use. Some of these water distribution systems have been in service for more than 100 years.

Small Systems  Water distribution systems that serve fewer than 10,000 people are considered to be “small systems.” They face unique challenges when it comes to compliance with the 1970 Safe Drinking Water Act and its major 1996 amendments.

Treatment Technologies  The technologies used to treat water so that it’s safe for human consumption is an important area of research for EPA. Scientists develop treatment technologies to address the formation and removal of disinfection by-products, pathogens such as Cryptosporidia and Giardia, and corrosion control.
