Unregulated Contaminant Monitoring Rule
On a five year cycle, the 1996 Safe Drinking Water Act (SDWA) amendments require the U.S. Environmental Protection Agency (EPA) to issue a new list of no more than 30 unregulated contaminants to be monitored by public water systems under the Unregulated Contaminant Monitoring Rule (UCMR) .
Unregulated contaminants are those that do not yet have a drinking water standard set by EPA. Our water system sampled the first series of unregulated contaminants for the occurrence of Cyanotoxins in our drinking water in 2018. The results are provided at links below. In 2019, a second series of sampling will be conducted for additional unregulated contaminants, with the first in that series to be completed in June. Results from the June 2019 sampling will be posted here as soon as they are available. Three more sampling events are scheduled for September 2019, December 2019 and March 2020. Notification of the availability of results for those samplings will be included with your City of Tampa utility bill.
Unregulated contaminant monitoring provides data to the EPA to determine if and where certain contaminants may occur and whether the EPA should consider regulating those contaminants for the protection of public health.
