Safe Drinking Water Information System (Water System) (SDWIS[WS]) — SDWIS Water Systems can have one or more water system facilities. The water system will purchase water from several facilities. Drinking water information is stored in EPA's SDWIS. SDWIS contains information about public water systems and their violations of EPA's regulations for safe drinking water. These statutes and accompanying regulations establish maximum contaminant levels (MCLs), treatment techniques, and monitoring and reporting requirements to ensure that water provided to customers is safe for human consumption. The SDWIS(WS) from facility information query form can be accessed at http://www.epa.gov/enviro/html/fii/fii_query_java.html.

Superfund Information — The National Priorities List (NPL) is a published list of hazardous waste sites in the country that are eligible for extensive, long-term cleanup under the Superfund program. To evaluate the dangers posed by hazardous waste sites, the U.S. EPA has developed a scoring system called the Hazard Ranking System. EPA uses the information collected during the assessment phase of the process to score sites according to the danger they may pose to public health and the environment. Sites that score high enough on the Hazard Ranking System are eligible for the NPL. Once a site is scored and meets the criteria, EPA proposes that it be put on the list. A site may also be proposed for the NPL, if the Agency for Toxic Substances and Disease Registry issues a health advisory for the site or if the site is chosen as the state's top priority site. The proposal is published in the Federal Register and the public has an opportunity to comment in writing on whether the site should be included on the NPL. To obtain more information on a proposed site, contact your community relations coordinator. The NPL sites list can be viewed at http://www.epa.gov/superfund/sites/npl/index.htm.

 

Toxics Release Inventory — The Toxics Release Inventory (TRI) contains information about more than 650 toxic chemicals that are being used, manufactured, treated, transported, or released into the environment. Manufacturers of these chemicals are required to report the locations and quantities of chemicals stored on-site to state and local governments. The reports are submitted to the EPA and state governments. EPA compiles this data in an online, publicly accessible national computerized database. You may use the Toxic Releases Query for basic facility information and chemical reports, which tabulate air emissions, surface water discharges, releases to land, underground injections, and transfers to off-site locations. TRI from facility information query form can be accessed at http://www.epa.gov/enviro/html/fii/fii_query_java.html

 

 

Underground Injection Code (UIC) — The UIC program works with state and local governments to regulate injection wells in order to prevent them from contaminating drinking water resources. EPA defines the five classes of wells according to the type of waste they inject and where the waste is injected. The UIC from facility information query form can be accessed at http://www.epa.gov/enviro/html/fii/fii_query_java.html
