The bill H. 4655 proposes to amend the South Carolina Code of Laws by adding Article 25 to Chapter 55, Title 44, which mandates the Department of Environmental Services to conduct quarterly testing for urinary metabolites in wastewater treatment facilities. The testing must be performed by accredited or certified environmental laboratories and will focus on specific urinary metabolites, including benzophenone, bisphenol A, estrone, ethinyl estradiol, musk ketone, pregnanediol, testosterone, tonalide (AHTN), mifepristone, and any other organic substances as required by the department.

The bill outlines the criteria for selecting wastewater treatment facilities for testing, which includes facilities near municipalities of varying population sizes. The department is required to maintain detailed records of all testing, including sample collection dates, locations, testing dates, and results, which must be published on the department's website. This act will take effect upon approval by the Governor.
