2020 Annual Drinking Water Quality Report

Big Bend Water Authority

We're pleased to present to you this year's Annual Water Quality $eport. This report is designed to inform you about the quality water and services we deliver to you every day. Our constant goat is to provide you with a safe and dependable supply of drinking water. We want you to understand the efforts we make to contihually improve the water treatment process and protect our water resources. We are committed to ensuring the quality ofyour water. Our water sources are groundwater from 2 wells drawing from the Floridan Aquifer. We treat your water with filtration using aluminum sulfate and feed a polyphosphate for corrosion control and chlorinatefor disinfection.

The sources ofdrinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels over the surface of the land or through the ground, it dissolves naturally occurring minerals and, in some cases, radioactive material, and can pick up substances resultingfrom the presence ofanimals orfrom human activity.

In 2020the Department of Environmental Protection performed a Source Water Assessment on our system. The assessment was conducted to provide information about any potential sources of contamination in the vicinity of our wells. There are four potential sources ofcontamination identifiedfor this system with a low to moderate susceptibility level. The assessment results are available on the FDEP Source Water Assessment and Protection Program website at This report shows our water quality results and what they mean.

Ifyou have any questions about this report or concerning your water utility, please contact: Garrett Doddat our office (352) 4983576. We encourage our valued customers to be informed about their water utility. Ifyou want to learn more, please attend any of our regularly scheduled meetings. They are held on the first Tuesday of each month at 5:00 PM at the Big Bend Water Authority Plant.

The Big Bend Water Authorityroutinely 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 ofour monitoringfor the periodofJanuary 1 to December 31, 2020. Data obtained bgfore January 1, 2018,and presented in this report are from the most recent testing done in accorda.nce with the laws, rules, and regulations.

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

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 risk to health. MCLGs allowfor a margin ofsafety.

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

Maximum Residual Disinfectant Level(MRDL).• The highest level of a disinfectant allowed in drinking water. There is convincing evidence that addition ofa disinfectant is necessaryfor control ofmicrobial contaminants.

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

Parts per billion (ppb) or Micrograms per liter (gg/l) — one part by weight ofanalyte to I billion parts by weight ofthe water sample.

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

Picocurie per liter (pCi/L) - measure ofthe radioactivity in water.
