201 7 Annual Drinking Water Quality Report Everglades City PWS# 5110089 We're pleased to present to you this year's Annual Water Quality Report. This report is designed to inform you about the qua lity water and services we deliver to you every day. Our c onstant goal is to provide you with a safe and dependable supply of drinking water. We want you to understand the efforts we make to continually improve the water treatment process and protect our water resources. We are committed to ensuring the quality of your water. Our water source is the Surficial Aquifer. The water is then treated with Nano Technology and chloraminated for disinfection. If you have any questions about this report or concerning your water utility, please call the office at 239 695 3781. Everglades City routinely monitors for contaminants in your drinking water according to Federal and State laws, rules, and regulations. Exce pt where indicated otherwise, this report is based on the results of our monitoring for the period of Januar y 1 to December 31, 201 7 Data obtained befor e January 1, 201 7 and presented in this report are from the most recent testing done in accordance 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 or 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 avai lable treatment technology. Maximum Contaminant Level Goal or MCLG : The level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow for a margin of safety. Action Level (AL) : The concentration of a conta minant that, if exceeded, triggers treatment or other requirements that a water system must follow. Maximum residual disinfectant level or MRDL : The highest level of a disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants. Maximum residual disinfectant level goal or MRDLG : The level of a drinking water disinfectant below which there is no known or expected risk to health. MRDLGs to 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 (g/L) : o ne part by weight of analyte to 1 billion parts by weight of the water sample. In 201 7 a source water assessment was conducted for our water system. The assessment found no potential sources of contamination n ear the wells.

Lea d in drinking water is pr imarily from materials and components associated with service lines and home plumbing. Everglades City is responsible for pr oviding high quality drinking water, but cannot control the variety of materials used in plumbing components. When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using water f or drinking or cooking. If you are concerned about lead in your water, you may wish to have your water te sted. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline or at http://www.epa.g ov/safewater/lead. The sources of drinking water (both tap water and bottled water) include rivers, lakes, strea ms, 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, rad ioactive material, and can pick up substances resulting from the presence of a nimals or from human activity. Contaminants that may be present in source water include: (A) Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septic systems, agricultur al livestock operations, and wildlif e. (B) Inorganic contaminants, such as salts and metals, which can be naturally occurring or result from urban stormwater runoff, industrial or domestic wastewater discharges, oil and gas production, mining, or farming. (C) Pesticides and herbicides, which may come from a variety of sources such as agriculture, urban stormwater runoff, and residential uses. (D) Organic chemical contaminants, including synthetic and volatile organic chemicals, which are by products of industrial processes and petroleum produ ction, and can also come from gas stations, urban stormwater runoff, and septic systems. (E) Radioactive contaminants, which can be naturally occurring or be the result of oil and gas production and mining activities. In order to ensure that tap water is safe to drink, the EPA prescribes regulations, which limit the amount of certain contaminants in water provided by public water systems. The Food and Drug Administration (FDA) regulations establish limits for contaminants in bottled wat er, which must prov ide the same protection for public health. Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that the water poses a healt h risk. More information about contaminants and potential health effects can 800 426 4791. Some people may be more vulnerable to contaminants in drinking w ater than the general population. Immuno compromised persons such as persons with cancer undergoing chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or other immu ne system disorders, some elderly, and infants can be particul arly at risk from infections. These people should seek advice about drinking water from their health care providers. EPA/CDC guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other m icrobiological contaminants are avail able from the Safe Drinking Water Hotline (800 426 4791).
