Show THE OGDEN VALLEY NEWS Page 20 Volume VI, Issue I April 15, 2002 2001 Annual Drinking Water Quality Report of the Eden Waterworks Company We’re pleased to present to you this year’s Annual Drinking Water Quality Report. This report is designed to inform you about the quality of the 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 protection of our water resources. We are committed to ensuring the quality of your water. Our water sources are the Burnett Springs, and the Clark East Well. Eden Waterworks Company has a Drinking Water Source Protection Plan that is available for review to our customers at our office. It provides more information such as potential sources of contamination and our source protection areas. I’m pleased to report that our drinking water is safe and meets federal and state requirements. If you have any questions about this report, or questions concerning your water utility, please contact Jess Ogden at 745-2081, or Thom Summers at 745-1549. We want our valued customers to be informed about their water utility. If you want to learn more, please attend any of our regularly scheduled stockholder’s meetings. They are held in October of each year. Eden Waterworks Company routinely monitors for constituents in our drinking water in accordance with Federal and Utah State laws. The following table shows the results of our monitoring for the period of January 1 to December 31, 2001. All drinking water, including bottled drinking water, may be reasonably expected to contain at least small amounts of some constituents. It’s important to remember that the presence of these constituents does not necessarily pose a health risk. Eden Waterworks Company has a Drinking Water Source Protection Plan that is TEST RESULTS Contaminant available for review. It provides more information such as potential sources of contamination and our source protection areas. It has been determined we have a low, susceptible level to potential sources of contaminatin, such as roads. If you have any questions regarding source protection, contact the office to review our source protection plan. Our source is in a remote location, and there are no potential contamination sources in the protection zones, so we consider our source to have a low susceptibility to potential contamination events. In the following table you will find many terms and abbreviations you might not be familiar with. To help you better understand these terms we’ve provided the following definitions: Non-Detects (ND) - laboratory analysis indicates that the constituent is not present. ND/Low - High - For water systems that have multiple sources of water, the Utah Division of Drinking Water has given water systems the option of listing the test results of the constituents in one table, instead of multiple tables. To accomplish this, the lowest and highest values detected in the multiple sources are recorded in the same space in the report table. Parts per million (ppm) or Milligrams per liter (mg/l) - one part per million corresponds to one minute in two years or a single penny in $10,000. Parts per billion (ppb) or Micrograms per liter (ug/l) – one part per billion corresponds to one minute in 2,000 years, or a single penny in $10,000,000. Parts per trillion (ppt) or Nanograms per liter (nanograms/l) – one part per trillion corresponds to one minute in 2,000,000 years, or a single penny in $10,000,000,000. Parts per quadrillion (ppq) or Picograms per liter (picograms/l) - one part per quadrillion corresponds to one minute in 2,000,000,000 years or one penny in $10,000,000,000,000. Violation Level Unit MCLG Y/N Detected Measurement MCL Date Sampled Likely Source of Contamination Picocuries per liter (pCi/L) - picocuries per liter is a measure of the radioactivity in water. Millirems per year (mrem/yr) - measure of radiation absorbed by the body. Million Fibers per Liter (MFL) - million fibers per liter is a measure of the presence of asbestos fibers that are longer than 10 micrometers. Nephelometric Turbidity Unit (NTU) - nephelometric turbidity unit is a measure of the clarity of water. Turbidity in excess of 5 NTU is just noticeable to the average person. Action Level (AL) - the concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow. Treatment Technique (TT) - (mandatory language) A treatment technique is a required process intended to reduce the level of a contaminant in drinking water. Maximum Contaminator Level (MCL) (mandatory language) The “Maximum Allowed” (MCL) is 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) (mandatory language) The “Goal” (MCLG) is 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. Date - Because of required sampling time frames i.e. yearly, 3 years, 4 years and 6 years, sampling dates “may” seem out of date. Waivers (W) - Because some chemicals are not used or stored in areas around drinking water sources, some water systems have been given waivers that exempt them from having to take certain chemical samples. These waivers are also tied to Drinking Water Protection Plans.

MCL’s are set at very stringent levels. To understand the possible health effects described for many regulated constituents, a person would have to drink 2 liters of water every day at the MCL level for a lifetime to have a one-in-a-million chance of having the described health effect. Some people may be more vulnerable to contaminants in drinking water than the general population. lmmuno-compromised persons such as people 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 advise from their health care providers about drinking water. 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 Eden Waterworks Company 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. Please call our office if you have questions.
