Environmental Protection Agency cleanup information site

The Environmental Protection Agency (EPA) identifies the most serious hazardous waste sites in the nation. These sites make up the National Priorities List (NPL) and are the sites targeted for long-term federal cleanup activities. Methyl parathion has been found in at least 16 of the 1,585 current or former NPL sites. However, the total number of NPL sites evaluated for this substance is not known. As more sites are evaluated, the sites at which methyl parathion is found may increase. This information is important because exposure to this substance may harm you and because these sites may be sources of exposure. 

The United States Environmental Protection Agency (U.S. EPA) has identified several hundred MTBE-contaminated sites that have performed treatment of soil and groundwater to remove or destroy MTBE.1 Many of these sites have also treated other fuel components, primarily benzene, toluene, ethylbenzene, and xylene (BTEX), and some have treated fuel oxygenates other than MTBE. Although others have reported about treatment technologies for MTBE cleanup,2 only limited information has been published about cleanup of other oxygenates. These oxygenates include ether compounds, such as ethyl tert-butyl ether (ETBE), tert-amyl methyl ether (TAME), diisopropyl ether (DIPE), and tert-amyl ethyl ether (TAEE), as well as alcohol compounds, such as tert-butyl alcohol (TBA), tert-amyl alcohol (TAA), ethanol, and methanol. 

This Statement was prepared to give you information about heptachlor and heptachlor epoxide and to emphasize the human health effects that may result from exposure to them. The Environmental Protection Agency (EPA) has identified 1,300 hazardous waste sites as the most serious in the nation. These sites comprise the "National Priorities List (NPL) Those sites which are targeted for long-term federal cleanup activities. Heptachlor and heptachlor epoxide have been found in at least 129 and 87 of these sites, respectively. However, we do not know how many of the 1,300 NPL sites have been evaluated for heptachlor and heptachlor epoxide. As EPA evaluates more sites, the number of sites at which heptachlor and heptachlor epoxide are found may change. This information is important for you to know because heptachlor and heptachlor epoxide may cause harmful health effects and because these sites are potential or actual sources of human exposure to heptachlor and heptachlor epoxide.
