"Providing Hometown Reliability"
Once again, we are pleased to provide you with information on your drinking water supply.
We encourage public interest and participation in our community's decisions affecting your drinking water. Informed customers are our best allies in providing safe and sufficient drinking water. Regular Board meetings are normally held at 8:30 a.m. on Tuesdays before the 1st and 3rd Mondays of every month, at the MMU office, 75 East Morgan in Marshall, Missouri. Dates are subject to change, so check at the office to be sure.

Marshall's water comes from ten wells in the Missouri River alluvium in the Malta Bend area. The wells range in depth from 120 to 147 feet deep. The water quality is very good; it does, however, contain calcium and magnesium that cause what is referred to as "hard" or soap-consuming water. Iron is present also in levels that could cause laundry staining. The plant first aerates the water to remove iron, and then lime is added to soften the water. Fluoride is added to help prevent dental cavities, and chlorine is added to disinfect and to protect against contamination in the distribution system.
A Department of Natural Resources-conducted source water assessment for the MMU water system looked at the potential for contamination of MMU's wells. The assessment shows no known source of contamination within one mile of the well field. A copy of the assessment is available from MMU. Contact the MMU office at 660-886-6966.
The following table shows the results of our water-quality analyses. Every regulated contaminant that the laboratories detected in the drinking water, even in the very smallest amounts, is listed. The table lists the name of each substance, the highest level allowed by regulation, the ideal goal for public health, the amount detected, the usual source of the substance, a key to units of measurement, and footnotes with additional details.

All samples, except chlorine, were analyzed by the Department of Natural Resources' laboratory or by a certified laboratory under contract to DNR. Chlorine is analyzed onsite by MMU personnel.
In addition to the substances listed here, MMU monitors for several dozen other chemicals. For a complete list of monitored substances, when they were last monitored, the results, the monitoring frequency, and other information about MMU, please see the other links in this section of our website.
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. Contaminants that may be present in source water include:
In order to ensure that tap water is safe to drink, the Environmental Protection Agency (EPA) prescribes regulations which limit the amount of certain contaminants in water provided by public water systems. Food and Drug Administration regulations establish limits for contaminants in bottled water which must provide the same protection for public health.
Drinking water, including bottled water, reasonably may be expected to contain at least small amounts of some contaminants. The presence of contaminants does not indicate necessarily that water poses a health risk. More information about contaminants and potential health effects can be obtained by calling EPA's Safe Drinking Water Hotline (1-800-426-4791).
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 (Centers for Disease Control) guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline (1-800-426-4791).
