This paper presents particular case studies which demonstrate challenges faced by utilities in South Florida on their path to compliance with the requirements of the final Ground Water Rule (GWR) and Florida Administrative Code (FAC) 62-550.828.
Case studies include the City of Fort Lauderdale Peele-Dixie Water Treatment Plant, the City of Hallandale Beach Water Treat-ment Plant, the City of Plantation East and Central Water Treatment Plants and the City of Naples Water Treatment Plant. These water treatment plants were placed into service over 50 to 70 years ago as lime softening treatment facilities. In recent years, these plants have been ex-panded to accommodate increasing water demands and newer treatment technologies which complicated compliance with the GWR.
Each case study presents a different situation and high-lights individual approaches to managing the challenges of the GWR, either through compliance with four-log virus treatment or providing triggered source water monitoring requirements. For each utility, the most viable compliance option was selected based on careful consideration of any potential water quality impacts, operation and maintenance needs, and capital costs associated with various alternative scenarios proposed to achieve compliance.
