Water pollution is any contamination of water with chemicals or other foreign substances that are detrimental to human, plant, or animal health. These pollutants include fertilizers and pesticides from agricultural runoff; sewage and food processing waste; lead, mercury, and other heavy metals; chemical wastes from industrial discharges; and chemical contamination from hazardous waste sites. Worldwide, nearly 2 billion people drink contaminated water that could be harmful to their health.
What is NIEHS Doing?
- 14th Report on Carcinogens - A congressionally mandated, science-based, public health document that NTP prepares for the HHS Secretary. This cumulative report currently includes 248 listings of agents, substances, mixtures, and exposure circumstances that are known or reasonably anticipated to cause cancer in humans.
- Don't Be Bullied by Bacteria! Join the Fight for Clean Water!(515KB) - Brought to you by the grantee Mount Desert Island Water Quality Coalition and the Community Environmental Health Laboratory.
- Gulf Oil Spill Response Efforts - NIEHS activated programs throughout the institute to provide timely and responsive services following the Deepwater Horizon Gulf oil spill of 2010. NIEHS research efforts in this area continue.
- - The GuLF STUDY (Gulf Long-term Follow-up Study) is a health study for individuals who helped with the oil spill response and clean-up, took training, signed up to work, or were sent to the Gulf to help in some way after the Deepwater Horizon disaster. The National Institute of Environmental Health Sciences (NIEHS) is leading this research with the support of many local community groups. The study is funded by the Intramural Program of the NIEHS and the National Institutes of Health (NIH) Common Fund.
- Oil Spills - NIEHS Worker Training Program (WTP) awardees have provided resources, trainers, and subject matter expertise during many oil spill response and related cleanup operations. The following resources provide health and safety information for workers involved in oil spill response and cleanup activities
