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 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 sources are ground water from 5 wells. Well number one #1 is located at 810 South Hwy. 93, well number two #2 is located at 224 ½ Marcus St., well number four #4 is located at 422 West Main St., well number five #5 is located at 152 Kurtz Lane, and well number six #6 is located between Super One and K-Mart Stores. We have a source water protection plan available from our office that provides more information. This plan can be reviewed at the City Hall during normal working hours.

This report shows our water quality and what if means. If you have any questions about this or concerning your water quality, please contact the Director of Public Works, at (406) 363-2101, ext. 39. We want our valued customers to be informed about their water utility. If you want to learn more, please attend our regularly scheduled City Council meetings held on every 1st and 3rd Tuesday of each month at 7:00 P.M., in the City Hall.

The City of Hamilton Water System routinely monitors for constituents in your drinking water according to Federal and State laws. This table shows the results of our monitoring for the period of January 1st, 1998. "Some of our data in the tables are more than one year old, since certain chemical contaminants are monitored less than once a year. Our sampling frequency complies with EPA and State drinking water regulations."

In this 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:

  • 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 $10,000.00.

  • Parts per billion (ppb) or Micrograms per liter - one part per billion corresponds to one minute in 2,000 years, or a single penny in $10,000,000.00.

  • Action Level – 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 Contaminant Level – (mandatory language) The "Maximum Allowed" (MCL) is the highest level of a contaminant that is allowed in drinking water. MCL’s are set as close to the MCLG’s as feasible using the best available treatment technology.

  • Maximum Contaminant Level Goal – (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. MCLG’s allow for a margin of safety.

What does this mean? The table shows that our system uncovered a copper-monitoring problem this past year. The duration of the violation has been noted since the first round of monitoring in 1993. The potential adverse health effects are, "Copper is an essential nutrient, but some people who drink water containing copper in excess of the action level over a relatively short amount of time could experience gastrointestinal distress. Some people who drink water-containing copper in excess of the action level over many years could suffer liver or kidney damage. People with the Wilson’s Disease should consult their personal doctor. We are trying to correct this situation by making our water less corrosive to copper plumbing and fixtures found in household plumbing. This is being accomplished by chemically changing the pH of the drinking water. The water system has been monitoring subsequent rounds every six months to determine if the water is becoming less corrosive. This is the only violation we have encountered and we’re proud that your drinking water meets or exceeds all Federal and State requirements. We have learned through our monitoring and testing that some constituents have been detected. The EPA has determined that your water IS SAFE at these levels.

"All sources of drinking water are subject to potential contamination by constituents that are naturally occurring or are man made. Those constituents can be microbes, organic or inorganic chemicals, or radioactive materials."

 All drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminates 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.

Nitrates: As a precaution we always notify physicians and health care providers in the area if there is ever a higher than normal level of nitrates in the water supply. Lead: Lead in drinking water is rarely the sole cause of lead poisoning, but it can add to a person’s total lead exposure. All potential sources of lead I the household should be identified and removed, replaced or reduced.

 I our continuing efforts to maintain a safe and dependable water supply it may be necessary to make improvements in your water system. The costs of these improvements may be reflected in the rate structure. Rate adjustments may be necessary in order to address these improvements.

Some people may be more vulnerable to contaminates 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 crytosporidium and other microbiological contaminants are available from the Safe Drinking Water Hotline (800-426-4791).

Please call our office if you have questions. We at the City of Hamilton 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.

This 1999 Annual Drinking Water Quality Report will not be mailed out to individual water customers. If you would like a copy of this report call the Public Works Department at (406) 363-2101, print this copy, or request a copy at the City Hall.
