Water Quality Reports

Together with Tampa Bay Water, the region’s wholesale water supplier, we routinely monitor for contaminants and provide annual water quality reports to our customers.

The Environmental Protection Agency (EPA) requires monitoring for more than 80 drinking water contaminants, which are included in annual water quality reports if they are detected. Some of the data in the reports is more than a year old, because the concentrations of some contaminants are not expected to vary significantly from year to year.

We operate 10 community public water systems, and each system has its own report. Use the interactive map below and type your address in the white box to find out which report is for your area.

Unregulated Contaminant Monitoring Rule (UCMR4)

 Hillsborough County Public Utilities participated in the U.S. Environmental Protection Agency's (EPA) fourth round of the Unregulated Contaminant Monitoring Rule (UCMR4). The County was one of approximately 6,000 utilities nationwide that monitored for unregulated contaminants from 2018 through 2020.

The 1996 Safe Drinking Water Act (SDWA) amendments require that once every five years EPA issue a new list of no more than 30 unregulated contaminants to be monitored by public water systems under the UCMR. Unregulated contaminant monitoring helps the EPA to determine where certain contaminants occur and whether the EPA should consider regulating those contaminants for the protection of public health in the future.

Further information about the EPA's unregulated contaminant monitoring rule can be found at the EPA website or by calling the EPA's Safe Drinking Water Act Hotline at 1-800-426-4761.
