City of Menominee Water Quality Report

City of Menominee 2007 Water Quality Report

Dear Water Utility Custome= r;
We are pleased to present to you our Annual Wat= er Quality Report. We welcome this opportunity to inform you, about the high= quality of your drinking water. We take our responsibility of providing you with = safe drinking water very seriously, and our goal is to help you understand how= the data in this report supports the safety of consuming drinking water provi= ded by the City of Menominee. We welcome this opportunity to inform you that your drinking water meets = or exceeds all federal and state requirements.
Do I need to take special precautions?<= /o:p>
Some people may be more vulnerable to contamina= nts 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 the= ir health care providers. EPA/Centers for Disease Control (CDC) guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and = other microbial contaminants are available from the Safe Water Drinking Hotline (800-426-4791).
Where does my water come from?
The source of our water is the Bay of Green Bay and has been used by the City of Menominee since the late 1800's. Historical data shows it to be of high quality.
Source water assessment and its availability=
Future efforts to protect our fresh water sourc= e include a formal source water assessment completed by the Michigan Department of Environmental Quality. The assessment analyzes and rates the sensitivity = and susceptibility for potential contamination of our source water. The rating for Menominee is high on a scale from very low to High. Potential sources= of contamination include Hazardous or Solid Waste sites, Farming, and Indust= rial operations. A summary of the assessment is available upon request by contacting one of the individuals listed below.
Why are there contaminants in my drinking wa= ter?
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 water poses a health risk. More information about contaminants and potent= ial health effects can be obtained by calling the Environmental Protection Agency's (EPA) Safe Drinking Water Hotline (800-426-4791). 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 surfac= e 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:

Microbial Contaminants, such as viruses = and bacteria, that may come from sewage treatment plants, septic systems, agr= icultural livestock operations, and wildlife; I= norganic Contaminants, such as salts and metals, which can be naturally occurr= ing or result from urban storm water runoff, industrial, or domestic wastewat= er discharges, oil and gas production, mining, or farming; Pesticides and Herbicides, which may come from a variety of sources such as agriculture, urban storm water runoff, = and residential uses; Organic Chemical Contaminants, including synthetic and volatile organic chemicals, which are by-products of indust= rial processes and petroleum production, and can also come from gas stations, urban storm water runoff, and septic systems; 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 dr= ink, EPA prescribes regulations that limit the amount of certain contaminants = in water provided by public water systems.&= nbsp; Food and Drug Administration (FDA) regulations establish limits for contaminants in bottled water which must provide the same protection for public health.
How can I get involved?
Your water utility is managed as an enterprise = fund and all operations, maintenance, and replacement expenditures are finance= d entirely by user fees. Customers should consider themselves as investor-owners of = the system and customer inquiries, requests, and or suggestions are encourage= d by the utility. The Menominee Water and Wastewater utility board is responsi= ble for overseeing the operation of the utility, and they meet on the second Thursday of each month at four (4) PM in the council chambers attendance = is encouraged. Any correspondence may be directed to one of the individuals listed above.
Total Organic Carbon (TOC) Explanation
Total Organic Carbon is naturally occurring and= it's removal is calculated as the ratio between the = actual TOC removed and the TOC removal requirements.
Water Quality Data Table<= /p>
The table below lists all of the drinking water contaminants that we detected during the calendar year of this report, un= less otherwise noted. The presence of contaminants in the water does not necessarily indicate that the water poses a health risk. The EPA or the S= tate requires us to monitor for certain contaminants less than annually because the concentrations of these contaminants do not change frequently.
