2007 Water Quality Report of the Pace Water System

 

2007 Water Quality Report

We're pleased to present to you this year's Annual Water Quality Report.  This report is designed to inform you about the quality water and services we deliver to you every day.  Our constant 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 ground water pumped from ten (10) wells located in the sand and gravel aquifer.  Treatment of the water consists of chlorination and lime addition.

In 2004 the 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 nine (9) potential sources of contamination identified for this system with low to high susceptibility levels.  The assessment results are available on the FDEP Source Water Assessment and Protection Program website at www.dep.state.fl.us/swapp or they can be obtained from Ronnie Hicks, Water Manager at (850)994-5129.

If you have any questions about this report or concerning your water utility, please contact Ted Dotson, General Manager at (850)994-5129. We encourage our valued customers to be informed about their water utility. If you want to learn more, please attend any of our regularly scheduled meetings. They are held on the second Tuesday of every month at 7:00 p.m. in the Water System Board Room located at 4401 Woodbine Road, Pace, Florida 32571.

Pace Water System 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, 2007.  Data obtained before January 1, 2007, 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:

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

Initial Distribution System Evaluation (IDSE):  An important part of the Stage 2 Disinfection Byproducts Rule (DBPR).  The IDSE is a one-time study conducted by water systems to identify distribution system locations with high concentrations of trihalomethanes (THMs) and haloacetic acids (HAAs). Water systems will use results from the IDSE, in conjunction with their Stage 1 DBPR compliance monitoring data, to select compliance monitoring locations for the Stage 2 DBPR.

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 available 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.

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 do not reflect the benefits of the use of disinfectants to control microbial contaminants. 

ND” means not detected and indicates that the substance was not found by laboratory analysis.   

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.

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.

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

We failed to complete required sampling for tap water bacteriological sampling on time and therefore were in violation of monitoring and reporting requirements.  We are required to monitor your drinking water for total coliform bacteria on a regular basis. Coliforms are bacteria that are naturally present in the environment and are used as an indicator that other, potentially-harmful, bacteria may be present.  Results of regular monitoring are an indicator of whether or not our drinking water meets health standards.  On October 2, 2007, one location within the distribution system indicated the presence of total coliform bacteria.  Normally, the collection of three repeat samples should immediately follow the discovery of any one contaminated sample.  Pace Water System, Inc. only collected one of the required repeat distribution samples; this sample was absent of total coliform.  Additionally the remainder of October’s samples have been collected and these too were absent of total coliform.  We have reviewed and updated our bacteriological sampling procedures in hopes that this situation will not occur again.

The sources of drinking 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 resulting from the presence of animals 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, agricultural livestock operations, and wildlife.

(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 production, 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 water, which must provide 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 health risk.  More information about contaminants and potential health effects can be obtained by calling the Environmental Protection Agency’s Safe Drinking Water Hotline at 1-800-426-4791.

Thank you for allowing us to continue providing your family with clean, quality water this year. In order to maintain a safe and dependable water supply, we sometimes need to make improvements that will benefit all of our customers. These improvements are sometimes reflected as rate structure adjustments. Thank you for understanding.

Some people may be more vulnerable to contaminants in drinking water 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 immune system disorders, some elderly, and infants can be particularly 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 microbiological contaminants are available from the Safe Drinking Water Hotline (800-426-4791).

We at Pace Water System work around the clock to provide top quality water to every tap.  We ask that all our customers help us protect our water sources, which are the heart of our community, our way of life and our children’s future.
