Endocrine Disruptors

According to a mid-February Huff Post article, it is now recognized that humans can be exposed to endocrine disruptors through drinking water. Endocrine disruptors have been detected in both ground and surface water. Under the Safe Drinking Water Act, there is no requirement to analyze for the presence of endocrine-active chemicals such as bisphenol A, alkylphenols, ethinylestradiol and others in our treated drinking water. Likewise, there is no such requirement under the Clean Water Act to test for these chemicals in our wastewater. In our surface waters, the most significant sources of endocrine-active chemicals most likely are the effluent from municipal wastewater treatment plants. Many estrogenically active compounds, such as estradiol and derivative compounds, are treated to levels of 80 percent or greater by secondary treatment of municipal wastewater. That still leaves significant concentrations of endocrine-active chemicals that are discharged to receiving waters via treated municipal wastewater. These and other sources of these compounds have significant impacts on aquatic systems including, but not limited to, reproductive impacts on fish populations and invertebrates.
