DU compliant with new EPA regs

On April 10, 2024, the U.S. Environmental Protection Agency released information regarding its final rule establishing drinking water standards and maximum contaminant levels (MCL) for six per- and polyfluoroalkyl substances (PFAS).

Within five years (2029), DU and other systems will be required to have PFAS levels that are below the final MCL enforceable levels listed above. For the past seven quarters reported, Decatur Utilities drinking water test results have been BELOW the new MCLs.

By 2027, DU and other water systems must include results of initial monitoring  and regular monitoring for PFAS for compliance in its annual Consumer Confidence Report as well as issue public notifications for any monitoring or reporting violations. PFAS testing data is currently included in DU's annual Consumer Confidence Report.


"We have been expecting this final rule for several months," said Ray Hardin, General Manager for Decatur Utilities. "In the fall of 2022, we proactively engaged Jacobs Engineering, a nationally-renowned expert in PFAS treatment, to perform a study to recommend PFAS treatment options alternatives that will ensure PFAS levels are below the new MCLs. That study is in its concluding phase and we will have the final recommendations in the next few months. DU will review the alternatives and select the best treatment option(s) for a 12-18 month pilot test at the Water Treatment Plant.  Following that test, DU will begin the process of designing and implementing the final selected treatment option."


Hardin stressed that DU takes compliance with EPA standards very seriously.


"Our customers can be assured that DU will take the steps necessary to continue our compliance with the new standards," he said. "Our mission has always been - and continues to be - providing safe drinking water that meets or exceeds all EPA mandates for safety and quality."


For a comprehensive look at DU’s water quality testing results, customers can visit to view and download the 2024 Consumer Confidence Report with results for testing between Jan - Dec, 2023. Customers will receive a hard copy of the report in their May bills.
