Water Quality Reports

2020 Annual Drinking Water Quality
Report City of Trenton 2211188

We’re very pleased to provide you with this year’s Annual Water Quality Report. We want to keep you informed about the excellent water and services we have delivered to you over the past year. Our goal is and always has been, to provide you a safe and dependable supply of drinking water. Our water source is groundwater from a well. The well draws from the Florida Aquifer. Our water is obtained from groundwater sources and is chlorinated and aerated for disinfection and odor purposes.

In 2020, the Department of Environmental Protection has performed a Source Water Assessment on our system. These assessments were conducted to provide information about any potential sources of contamination in the vicinity of our wells. There were three potential sources of contamination with moderate to high susceptibility levels identified for this system. The assessment results are available on the DEP Source Water Assessment and Protection Program website at www.dep.state.fl.us/swapp.

If you have any questions about this report or concerning your water utility, please contact Lyle Wilkerson at 352-463- 4000. We encourage our valued customers to be informed about their water utility.

The city of Trenton routinely monitors for contaminants in your drinking water according to Federal and State laws, rules, and regulations. Except where indicated otherwise, this report is based on the results of our monitoring for the period of January 1 to December 31, 2020. Data obtained before January 1, 2020, and presented in this report are from the most recent testing done in accordance with the laws, rules, and regulations.

As authorized and approved by EPA, the State has reduced monitoring requirements for certain contaminants to less often than once per year because the concentrations of these contaminants are not expected to vary significantly from year to year. Some of our data [e.g., for organic contaminants], though representative, is more than one year old.

In the table below, you may find unfamiliar terms and abbreviations. To help you better understand these terms we’ve provided the following definitions:

Action Level (AL): The concentration of a contaminant that, if exceeded, triggers treatment or other requirements that a water system must follow.

Maximum Contaminant Level (MCL): The highest level of a contaminant that is allowed in drinking water. MCLs are set as close to the MCLGs as feasible using the best available treatment technology.

Maximum Contaminant Level Goal (MCLG): The level of a contaminant in drinking water below which there is no known or expected health risk. MCLGs allow for a margin of safety.

Maximum Residual Disinfectant Level (MRDL): The highest level of a disinfectant allowed in drinking water. There is convincing evidence that the addition of a disinfectant is necessary for the control of microbial contaminants.

Maximum Residual Disinfectant Level Goal (MRDLG): The level of a drinking water disinfectant below which there is no known or expected health risk. MRDLGs do not reflect the benefits of the use of disinfectants to control microbial contaminants.

Parts per million (ppm) or Milligrams per liter (mg/l) – one part by weight of analyte to 1 million parts by weight of the water sample.

Parts per billion (ppb) or Micrograms per liter (μg/l) – one part by weight of analyte to 1 billion parts by weight of the water sample.

We failed to submit required bacteriological sampling results on time during the September 2020 monitoring period, and Lead/Copper tap sample results on time during the July- September 2020 monitoring period and therefore were in violation of monitoring and reporting requirements. This violation has no impact on the quality of the water our customers received, and it posed no risk to public health. We have a report tracking file to ensure that all reporting requirements are met in the future.
