Explanation:
The Department of Public Utilities ("Department") maintains and operates a 59.5 million gallons per day ("MGD") Water Treatment Plant ("WTP"). Although the WTP utilizes membrane reverse osmosis and nanofiltration, the best available technology for Per- and Polyfluoroalkyl Substance ("PFAS") removal, conventional lime softening treatment is also used at the WTP and does not remove PFAS.
PFAS are a group of manufactured chemicals that do not break down naturally in the environment and can migrate into soil and water, including drinking water sources. PFAS have recently been detected in WTP raw water wells. Environmental Protection Agency regulations require that these compounds be reduced to below four parts per trillion ("ppt") within five years of the rule, which will be by April 10, 2031.
Department staff have requested technical assistance to help determine the optimal treatment configuration to reduce PFAS levels to below four ppt within the required timeframe, including a corrosion control study dubbed the PFAS Phase 2B Corrosion Control Study ("PFAS Corrosion Study").
On August 30, 2023, the City Commission passed and adopted Resolution No. R-2023-251, which authorized the execution of continuing professional consulting engineering services agreements with five firms for WTP and Southern Regional Wastewater Treatment Plant Projects, one of the firms being Hazen and Sawyer, P.C. ("H&S").
