The Importance of UCMR Testing
The Tampa Water Department conducts over 9,000 water quality tests every year to ensure that your drinking water is safe to drink and is in compliance with all federal and state drinking water standards.
Every five years, the U.S. Environmental Protection Agency (EPA) implements the Unregulated Contaminant Monitoring Rule (UCMR). The purpose of UCMR is to collect data from utilities like ours about contaminants that may be present in drinking water. The EPA uses this data to decide if specific contaminants occur at frequencies and concentrations high enough to be regulated in the future.
UCMR testing is part of the 1996 Safe Drinking Water Act.
The Tampa Water Department participated in the EPA’s fourth round of UCMR testing, known as UCMR4, which required us to monitor for a number of contaminants between 2018 and 2020. These contaminants included metals, pesticides, alcohols, semi-volatiles, brominated haloacetic-acid groups, disinfection by-product indicators and cyanotoxins.
It's important to keep in mind that no health standards (for example, maximum contaminant levels) have been established at the present time for any of these unregulated contaminants.
