Safe & Hydrating

St. Pete’s drinking water comes from a combination of ground and surface water, which undergoes a three-step treatment process before being distributed to residents. St. Pete is part of Tampa Bay Water, which also supplies drinking water to Hillsborough County, Pasco County, Pinellas County, New Port Richey and Tampa. More about the drinking water sources can be found below. 

Tampa Bay Water Sources

All of the city’s potable water is disinfected using chloramines, which is a safe, proven water treatment method used throughout the country. Read more information on St. Pete's water quality in the latest Water Quality Report below. 

Unregulated Contaminant Monitoring

The Water Resources Department is participating in the U.S. Environmental Protection Agency’s (EPA) Fourth Unregulated Contaminant Monitoring Rule (UCMR4). This program helps the EPA measure the occurrence of specific contaminants in drinking water and determine if they need to be regulated in the future. Currently, no health-based standards have been established for these unregulated contaminants under the Safe Drinking Water Act (SDWA). More information on the UCMR4 program can be found at epa.gov/dwucmr.

2022 Drinking Water Quality Report


Per- and Polyfluoroalkyl Substances (PFAS) are man-made compounds that have been widely used in the manufacturing of certain consumer products since the 1940s. The Environmental Protection Agency (EPA) is focused on a small number of these compounds that may have health effects at very low concentrations. It is not uncommon to find low levels of PFAS in drinking water sources as they are slow to break down when they enter our environment. When these products are used and discarded, they can release PFAS into the environment, including drinking water sources. 

The City of St. Petersburg and our drinking water distributor, Tampa Bay Water, are participating in a study to help the EPA determine regulations for unregulated contaminants, including per- and polyfluoroalkyl substances (PFAS). Testing of treated drinking water will begin in July 2023 and these results will be shared to support setting standards that protect public health. More information about PFAS can be found at www.tampabaywater.org/pfas
