Endocrine-disrupting compounds (EDCs) are progressively becoming a threat to human health through the environment. These harmful compounds can be found in plastics, pharmaceuticals, personal care products, and industrial chemicals. EDCs are hazardous to human health because of their potential to alter hormonal development and reproduction for up to four generations. The purpose of this project was to assess whether the United States Environmental Protection Agency (EPA) should reevaluate the current Maximum Contaminant Level (MCL) of 6 parts per billion for Di(2-ethylhexyl)phthalate (DEHP), a plasticizer and known EDC in drinking water. In 1974, the EPA established the Safe Drinking Water Act (SDWA) to supervise the quality of drinking water in the U.S. Under the SDWA, National Primary Drinking Water Regulations were established to create MCLs for drinking water. Several risk assessments and peer reviewed articles were used to assess the policy regulation for DEHP in drinking water. Three interviews were conducted with government and industry experts to substantiate previously reviewed risk assessment findings that suggested the possibility of MCL reassessment and to identify if a more stringent policy for drinking water regulation was needed in the U.S. This study recommends that EPA should not reassess the current DEHP MCL.
