EPA continues sampling and testing efforts in Flint

The Environmental Protection Agency (EPA) recently completed sampling and testing areas of the Flint, Michigan water system for chlorine as part of its larger sampling efforts, showing that chlorine is present in the system.

The samples collected by the EPA were taken from areas likely to have low levels of chlorine, and while some areas could see improved levels of the bacteria-inhibiting chemical, the sample with the lowest concentration of chlorine did not show any coliform or E. coli. As part of the agency’s ongoing work in Flint, it will continue sampling and testing to ensure suitable chlorine levels throughout the city.

The agency is also gathering samples, with the assistance of the Michigan Department of Environmental Quality and Flint residents, to ensure that filters distributed to remove lead from household water throughout the city are working. These samples, which are being collected in wide-mouthed bottles to ensure that they are taken in similar conditions to filling a glass, will also be useful in garnering information about which types of plumbing materials are most susceptible to corrosion.
