We're pleased to present to you this year's Annual Quality Water 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 continually make to improve the water treatment process and protect our water resources. Your water utility is currently staffed by 2 certified water plant operators;  Tom Thompson and Steve O’Braza.  In addition to these operators, Dylan Knudsen is also working for us as an operator in training. Dylan is currently a certified well driller. We are working hard to provide the City of Carlisle with a safe and plentiful supply of drinking water.  We are committed to ensuring the quality of your water. Our water source is 6 wells located just north of the North River and to the east of the Avon Highway.  The water is drawn from an underground water source called an aquifer and is comprised of a sand and gravel mix. The Carlisle Water Facility drilled a new well and it is currently  online.  The new well will ensure we have a plentiful water supply for growing city demands.

A Source Water Assessment and Protection program was completed on Carlisle’s aquifer and no contamination sources were found in our water protection area.  Due to the characteristics of the aquifer it is highly susceptible to contamination.  Carlisle’s wells will be most susceptible to activities such as dry cleaners, gas stations, industrial sites and wastewater discharges.  A detailed evaluation of our source water was completed by the Iowa Department of Natural Resources, and is available from The Carlisle Water Department at 989-0125 or 989-3224.

NO VIOLATIONS

  The City is pleased to report that our drinking water is safe and meets federal and state requirements.

If you have any questions about this report or concerning your water utility, please contact CARLISLE CITY HALL AT 989-3224 OR THE WATER TREATMENT PLANT AT 989-0125 AND ASK FOR STEVE O’BRAZA (WATER SUPERINTENDENT). Regular business hours are Monday through Friday 8am to 5 PM.  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 meetings. They are held on the second and fourth Mondays of every month. The meetings begin at 7:00pm.

 The Carlisle Water Facility routinely monitors for over 80 contaminants in your drinking water according to Federal and State laws. This table shows the results of our monitoring for the period of January 1^st to December 31^st, 2005 unless otherwise noted.  All drinking water, including bottled drinking water, may be reasonably expected to contain at least small amounts of some contaminants.  It's important to remember that the presence of these contaminants does not necessarily pose a health risk. Even though some contaminants have been detected, the EPA has determined the drinking water is Safe at these levels.  Not all contaminants are monitored on an annual basis, therefore, some tests may have been taken before 2006.

     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.  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.

DEFINITIONS…( used in the table and throughout the report)

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

2. (MCLG) Maximum Contaminant Level Goal - 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.

3. Ppb or ug/l -- parts per billion.

4. ppm - parts per million.

5. pCi/L - picocuries per liter

6. N/A - Not applicable

7. ND - Not detected

8. TT - is treatment technology. A required process intended to reduce the level of a contaminant in drinking water. 

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

10. (MRDLG - Maximum Residual Disinfectant Level Goal - 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.

11. (MRDL) - Maximum Residual Disinfectant Level  - 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.

Our water quality testing shows the following results:
