Pasco County sits north of Tampa, home to about 570,000 residents in one of the fastest-growing areas of the Tampa Bay region. Water comes from the Floridan Aquifer and from Tampa Bay Water's regional system, which blends surface water, groundwater, and desalinated water. Pasco County Utilities operates the largest system, supplemented by smaller providers.
Pasco County's groundwater from the Floridan Aquifer is naturally hard and contains hydrogen sulfide, typical of central Florida. Treatment includes aeration, softening, and disinfection. UCMR5 data shows PFAS detections in county systems, though at generally lower levels than in neighboring Hillsborough County, which hosts MacDill AFB.
According to the Florida DEP's 2024 monitoring data, three public water systems in Pasco County reported PFAS above detection thresholds. The county does not host major military installations, so PFAS sources are primarily diffuse – landfills, commercial operations, and stormwater runoff.
Pasco County's rapid growth means new development areas are being connected to the water system continuously. New connections can experience initial variability as mains are flushed and stabilized.
