Palm Beach County serves approximately 1.5 million residents across a mix of coastal cities and inland agricultural communities. The county's water comes primarily from the Surficial Aquifer System, supplemented by wells drawing from the deeper Floridan Aquifer in some western areas. Multiple utilities operate independently – Palm Beach County Water Utilities, the cities of West Palm Beach, Boca Raton, and Boynton Beach among the largest.
Like other South Florida counties, Palm Beach faces the dual challenge of saltwater intrusion and PFAS contamination. The USGS has mapped the saltwater front advancing into the Surficial Aquifer along the coast, threatening eastern wellfields. Some coastal utilities have already shifted to deeper wells or alternative sources.
UCMR5 data shows PFAS detections across several Palm Beach County water systems. Palm Beach International Airport and the former Palm Beach Air Force Base site are potential PFAS sources. According to the Florida DEP's 2024 statewide survey, nine public water systems in the county reported at least one PFAS compound above detection limits. Agricultural runoff from the western part of the county – one of the state's most productive farming regions – adds nitrate and pesticide concerns to the groundwater picture.
Coastal and inland communities in Palm Beach County face different water quality challenges. Eastern areas deal with saltwater intrusion; western areas near agricultural operations face runoff contaminants.
Check your water for data specific to your provider and ZIP code. For PFAS and broad contaminant protection, reverse osmosis is the most effective single filter type.
