MILL CREEK WATER DISTRICT • 6415 Hickory Grove N • Quincy, IL 62305 • ABOUT US • REPORT PDF • BILLING • CONTACT US MILL CREEK WATER DISTRICT Board Meeting is First Tuesday of the Month at 7:30 am Mill Creek Water District News WATER USE SURVEY MILL CREEK WATER DISTRICT – The Illinois Environmental Protection Agency (IEPA) requires every water supplier to develop and implement a comprehensive cross connection control program for the elimination of existing cross connections and prevention or protection from all future cross connections. Regulations are in place to protect our drinking water systems a requirement of the program is to conduct a survey of all water customers every three years. Mill Creek Water District water customers will receive a survey post card in the mail soon, if not already. Please simply follow the directions on the post card for completion of the survey. There is no cost and it takes only a few moments to complete. Surveys should be completed within 30 days of receipt of the post card. Mill Creek Water District is utilizing the services of Aqua Backflow to assist with program operations, including the survey. They specialize in cross connection control program management. Note that if you have or require backflow protection, you may be also notified for compliance (testing, repairs, or installations) by Aqua Backflow. Contact them at 847-742-2296 or info@AquaBackflow.com with any questions. Mill Creek Water District’s Cross Connection Control Program is designed to safeguard public health. We ask for your cooperation with our program, its enforcement, and any requests for information that comes from Aqua Backflow or Mill Creek Water District staff.
Sources of Drinking Water The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and groundwater 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.
Our source of water comes from 4 groundwater wells and a back-up water interconnect with purchased water from Quincy, IL.
Contaminants that may be present in source water include:
Other Facts about Drinking Water 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 potential health effects can be obtained by calling the EPA's Safe Drinking Water Hotline at (800) 426-4791.
In order to ensure that tap water is safe to drink, EPA prescribes regulations which limit the amount of certain contaminants in water provided by public water systems. FDA regulations establish limits for contaminants in bottled water which must provide the same protection for public health.
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 microbial contaminants are available from the Safe Drinking Water Hotline (800-426-4791).
If present, elevated levels of lead can cause serious health problems, especially for pregnant women and young children. Lead in drinking water is primarily from materials and components associated with service lines and home plumbing. We cannot control the variety of materials used in plumbing components. When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using water for drinking or cooking. If you are concerned about lead in your water, you may wish to have your water tested. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline or at http://www.epa.gov/safewater/lead.
Source Water Information
Source Water Assessments
Source water protection (SWP) is a proactive approach to protecting our critical sources of public water supply and assuring that the best source of water is being utilized to serve the public. It involves implementation of pollution prevention practices to protect the water quality in a watershed or wellhead protection area serving a public water supply. Along with treatment, it establishes a multi-barrier approach to assuring clean and safe drinking water to the citizens of Illinois. The Illinois EPA has implemented a source water assessment program (SWAP) to assist with wellhead and watershed protection of public drinking water supplies.
We want our valued customers to be informed about their water quality. If you would like to learn more, please feel welcome to attend any of our regularly scheduled meetings. The source water assessment for our supply has been completed by the Illinois EPA. If you would like a copy of this information, please stop by or call our office at (217) 224-9343.
To view a summary version of the completed Source Water Assessments, including: Importance of Source Water; Susceptibility to Contamination Determination; and documentation/recommendation of Source Water Protection Efforts, you may access the Illinois EPA website at http://www.epa.state.il.us/cgi-bin/wp/swap-fact-sheets.pl.
Source of Water: MILL CREEK PWD to determine Mill Creek PWD's susceptibility to groundwater contamination, a Well Site Survey, published in 1986 by the Illinois EPA, was reviewed. During the survey of Mill Creek PWD's source water protection area, Illinois EPA staff recorded potential sources, routes, or possible problem sites within the 400 foot minimum setback zones, the 1,000 foot Phase I Wellhead Protection Area (WHPA), and the Phase II WHPA for Wells #1, #2, #3 and #4. The Phase II WHPA, also referred to as the recharge area, is the geographic area surrounding a well or a well field providing potable water to a community water supply as modeled using computer software to determine a five-year time of travel. Fourteen potential sources of groundwater contamination are present that could pose a hazard to groundwater pumped by the Mill Creek PWD community water supply wells. These include a pile of material, a quarrying of material, a mining other than sand/gravel or stone, a below ground fuel storage, a manufacturing process, a septic tank, an electrical generator/substation, a fertilizer warehouse, an exterminator, two lagoons, a well, an above ground fuel storage, and a pesticide/fertilizer commercial application or warehouse. Approximately 60% (110 acres) of the Phase I and Phase II WHPAs is considered €ścultivated crops€ť, with the remaining percentage consisting of €śurban development€ť and €śdeciduous forest€ť (Figure 2). The United States Department of Agriculture (USDA) describes this Land Resource Region as the Central Feed Grains and Livestock Region. Further, USDA classifies this Major Land Resource Area as the Central Mississippi Valley Wood Slopes, Northern Part. The Cl/Br vs. Cl ratio indicates non-point source agriculture fertilizer, as a possible source of nitrate in the area of the wells. As noted in previous sections, the nitrate concentrations for well #3 ranged from 5.58 - 9.0 mg/L. The sample data is from samples collected bi-monthly starting in November 2014 through November 2016. Figure 3 shows the overall chloride and nitrate concentration during the sample period. The Illinois EPA considers the source water of this system to be susceptible to contamination. This determination is based on a number of criteria including: the land-use activities in the recharge area of the wells, the available hydrogeologic data, monitoring conducted at the wells, and monitoring conducted at the entry point to the distribution system. As noted above, the regional and local land use is primarily agriculture with some business, and the area around the wells is considered to have a €śvery high to moderately high€ť potential for aquifer recharge. All public water supplies using groundwater are required to sample their wells monthly for bacterial contaminants. Sampling performed to assess for pathogenic contamination (e.g., virus, total coliform, e-coli) has also demonstrated that the source water is not susceptible to these types of contaminants.
Source of Water: Quincy, Illinois, EPA considers all surface water sources of community water supply to be susceptible to potential pollution problems, hence, the reason for mandatory treatment for all surface water supplies in Illinois. Mandatory treatment includes coagulation, sedimentation, filtration, and disinfection. Within the Illinois portion of the Mississippi River Watershed, which is illustrated in Figure 3, many commodities, including manufactured goods, petrochemicals, and pesticides are transported along the river system. The production, storage, and transportation of these commodities are a major concern, especially when occurring near surface water intakes. In addition, agricultural runoff within the Illinois portion of the Mississippi River Basin contributes to the susceptibility of the Quincy intakes. With high flow rates and long distances of travel on the Mississippi River, critical areas can be extensive. The critical area for the Quincy intake was determined using data from a joint U.S. Environmental Protection Agency/U.S. Geological Survey project. This project used a computer modeling program (SPARROW) to determine travel times on major rivers in the United States. Accidental spills of hazardous materials into navigable waterways are a major concern because of their frequency in the United States in recent years. Illinois has access to 1,116 miles of inland waterway that can handle commercial barge traffic. These include the Upper Mississippi River, Illinois River Waterway, and the Ohio River. Along these waterways are numerous facilities that load and unload hazardous materials. Analysis of reported spills indicates that between 1974 and 1989, 794 accidental spills of hazardous materials occurred along Illinois waterways. Approximately 92% of these spills occurred along the Mississippi and/or the Illinois River. Figure 2 shows the critical area of concern (Zone 1) for the Quincy surface water intake. Spills occurring in this critical area will travel to the intake in five hours or less, making contingency planning and spill reporting a major concern in this watershed. Further information concerning spill response planning on the Mississippi River may be found in U.S. EPAs website at www.epa.gov/region5/oil and at U.S. Geological Surveys website ftp://ftp.umesc.er.usgs.gov/pub/gis_data/oil_spill.
