2007 ANNUAL DRINKING WATER QUALITY REPORT
VILLAGE OF MILFORD
March 10, 2008
We're pleased to present to you the 2007 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 source is from two 12-inch diameter water wells, 114 feet deep, owned by the Village of Milford. Our wells draw water from an underground aquifer that extends north towards Moore Lake in Milford Township. Once the water is pumped from the aquifer, the water is pumped to the Iron Removal Plant and filtered to remove the iron. Chlorine is added as a disinfectant to protect the water after it leaves the plant. Fluoride is added to the water as it leaves the plant to prevent tooth decay.
The State performed an assessment of our source water to determine the susceptibility or the relative potential of contamination. The susceptibility rating is on a seven-tiered scale from “very-low” to “very-high” based on geologic sensitivity, well construction, water chemistry and contamination sources. The susceptibility of our source water is moderate. Through our Well Head Protection Plan (WHPP) approved by the Michigan Department of Environmental Quality, we are making efforts to protect our source water supply. This is an important tool for the protection of our community’s drinking water source. Educating the public and our water customers on the proper disposal of chemicals, water conservation, and being informed of the source of our drinking water are important educational tools of a WHHP. One program provided to the residents of our community is the annual Household Hazardous Waste Collection Event (HHWCE) held on the third Saturday of May. All unused or unwanted chemicals, batteries, motor oil, herbicides, pesticides, electronics, oil based paints, solvents, etc. can be brought to the Milford Civic Center site for proper disposal. This program helps to reduce the chance of these chemicals contaminating the groundwater. Information on the WHPP or the HHWCE is available at the Village Offices or Department of Public Services
The Village of Milford routinely monitors for contaminants in your drinking water according to Federal and State laws. This table shows the results of our monitoring for the period of January 1st to December 31st, 2007.
If you have any questions about this report or concerning your water utility, please contact us. 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 Council meetings. They are held on the first and third Mondays of each month at 7:30 PM at the Village Offices.
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. It's important to remember that the presence of these constituents does not necessarily pose a health risk.
In the tables below, 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:
Not-Detected or (ND) means laboratory analysis indicates that the constituent is not present.
Parts per million (ppm) or Milligrams per liter (mg/l) –means that 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 - one part per billion corresponds to one minute in 2,000 years, or a single penny in $10,000,000.
Action Level or (AL) means the concentration of a contaminant, which, if exceeded, triggers treatment or other requirements, which a water system must follow.
Maximum Contaminant Level or (MCL) means the “maximum allowed” 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 or (MCLG) means the “goal” 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.
Maximum Residual Disinfectant Level Goal or MRDLG means 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.
Maximum Residual Disinfectant Level or MRDL means the highest level of a disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for control microbial contaminates.
The State allows us to monitor for certain contaminants less than once per year because the concentrations of these contaminants are not expected to vary significantly from year to year. The table below represents the most current testing information available.
Compounds reported as TRACE were detected at levels above the detection limits, but at levels too low to quantitate.

VOC’s are man-made chemicals such as paint thinner, dry cleaning fluid, solvents, and components of gasoline, other petroleum products and plastics.
Unregulated contaminants are those for which EPA has not established drinking water standards. Monitoring helps the EPA to determine where these contaminants occur and whether it needs to regulate those contaminants.

Lead and Copper Monitoring
In 2005, the Village of Milford Water Department staff collected samples drawn from 20 homes throughout the water system, based on EPA requirements to test for the presence of lead and copper in the drinking water. The test results below show the samples taken are well below the action level of 15 ppb for lead and 1.3 ppm for copper. The next round of testing will be conducted during June 1, 2008 to September 30, 2008. The state allows us to monitor for certain contaminates in water less than once a year because the concentrations of these contaminates are not expected to vary significantly from year to year. All of the data is representative of the water quality, but some are more than one year old.
