Safe drinking water is important to overall health and may aid in the prevention of certain birth defects, infectious diseases and exposure to harmful chemicals. There are currently more than 148,000 public water systems providing drinking water to Americans. The Environmental Protection Agency (EPA) sets a legal limit of no more than 90 contaminants in drinking water. Maximum contaminant levels, maximum residual disinfectant levels and treatment technique rules are all health-based drinking water standards.
Monitoring and enforcing health-based violations are critical to helping states and the EPA protect public health through safe drinking water. An estimated 3-10% of community water systems receive a health-based violation in any given year. Water contaminants such as arsenic, lead and nitrates have been strongly linked to gastrointestinal illnesses, cancer and neurodevelopmental damage in children.
The growth of production in the agriculture industry is one of the leading sources of drinking water contamination in America. While pesticides and fertilizers are used in many places, toxic runoff from these pollutants are found at higher readings in rural communities.
Children, the elderly, people of color, pregnant women and people with compromised immune systems are more vulnerable to the damaging health effects of contaminated water. Drinking water violations are higher among:
County Health Rankings and Roadmaps lists multiple programs and interventions that reduce water pollution. The EPA provides detailed information on drinking water violations and works with all states to ensure compliance with the Safe Drinking Water Act. Adopting a water safety plan with one’s community offers multiple benefits and has been shown to decrease contamination and improve regulation compliance.
The Environmental Working Group has a tool for checking contaminants in drinking water violations based on zip code and recommends the following:
Healthy People 2030 has an objective to increase the proportion of people whose supply of drinking water meets Safe Drinking Water Act regulations. Further, the EPA has implemented an initiative that aims to reduce the number of community water systems that are not in compliance with health-based standards.

America’s Health Rankings builds on the work of the United Health Foundation to draw attention to public health and better understand the health of various populations. Our platform provides relevant information that policymakers, public health officials, advocates and leaders can use to effect change in their communities.
We have developed detailed analyses on the health of key populations in the country, including women and children, seniors and those who have served in the U.S. Armed Forces, in addition to a deep dive into health disparities across the country.
