City of Coopersville Consumer Confidence Report (CCR)
for the year of 2020
Annual Drinking Water Quality Report
We are pleased to report that your drinking water meets, and often is better than, all state and federal guidelines for safe drinking water.
Our constant goal is to provide you with a safe and dependable supply of drinking water and this report is designed to inform you about the quality of the water we deliver to you every day. 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 and update this report annually. Additional copies of this report are available by calling the Water Department at 616-997-9731.
Is my water safe?
Yes. The City of Grand Rapids meets or exceeds all the requirements of the Safe Drinking Water Act (SDWA). We are pleased to present the 2020 Water Quality Report (Consumer Confidence Report) as required by the SDWA. This report is designed to provide details about where your water comes from, what it contains and how it compares to standards set by regulatory agencies. This report is a snapshot of last year's water quality. We are committed to providing you with information because we care about you and want you to be informed about the water you drink.
Where does my drinking water come from?
Lake Michigan, a surface water source, is the sole source of water treated for the Grand Rapids Water System.
Source Water Assessment
The Michigan Department of Environment, Great Lakes, and Energy (EGLE) completed a Source Water Assessment for the City of Grand Rapids water supply in 2003. This report found that our water supply has a moderately high susceptibility to contaminants. Source water contamination is not likely to occur if potential contaminants are properly used and managed. The Grand Rapids Water Treatment Plant routinely and continuously monitors the water for a variety of chemicals to ensure safe drinking water. The Grand Rapids Water System continues to be involved in and supports watershed protection efforts.
Why are there contaminants in my 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. 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 all of the following:
To ensure that tap water is safe to drink, Environmental Protection Agency (EPA) prescribes regulations that limit the amount of certain contaminants in water provided by public water supplies. Food and Drug Administration (FDA) regulations establish limits for contaminants in bottled water which must provide the same protection for public health. More information about contaminants and potential health effects can be obtained by calling the United States EPA’s Safe Drinking Water Hotline 800.426.4791.
Do I need to take special precautions?
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 may seek advice about drinking water from their health care providers. The Environmental Protection Agency (EPA)/Center 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 Drinking Water Hotline 800.426.4791.
Additional Information for Lead
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. The City of Grand Rapids is responsible for providing high-quality drinking water but 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 have a service line that is lead, galvanized previously connected to lead, or unknown but likely to be lead, it is recommended that you run your water for at least 5 minutes to flush water from both your home plumbing and the lead service line. If you are concerned about lead in your drinking water, you may wish to have your water tested.
The City of Coopersville has 1,391 water services in the water distribution system. Water services from the water main to the curb stop/shut off are owned/responsibility of the City. Water service lines from the curb stop/shut off valve to the home are private and are the responsibility of the property owner. In accordance with requirements from EGLE the City completed the preliminary distribution system material inventory (DSMI) in 2019. Estimated numbers of service connections by service line materials are as follows: Any portion contains lead: 1, contains galvanized previously connected to lead: 0, likely contains lead: 0, likely does not contain lead: 124, material is unknown: 74 and contains neither lead nor galvanized previously connected to lead: 1,190. Information pertaining to the preliminary DSMI was compiled by inspectors from various water meter replacement programs which have been verified by inspection record cards. The City will be completing a comprehensive DSMI by 2025 that will be submitted to EGLE. Under current EGLE lead and copper rules the City of Coopersville is replacing all lead service lines, whether they are City or privately owned, during capital improvement projects in accordance with asset management planning.
Infants and children who drink water containing lead could experience delays in their physical or mental development. Children could show slight deficits in attention span and learnings disabilities. Adults who drink this water over many years could develop kidney problems or high blood pressure.
Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available from the Safe Drinking Water Hotline 800.426.4791 or at http://www.epa.gov/safewater/lead.

Contaminants that may be present in source water include all of the following:
- Microbial contaminants such as viruses and bacteria, which may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife.
- Inorganic contaminants, such as salts and metals, which can be naturally occurring or result from urban stormwater runoff, industrial or domestic wastewater discharges, oil and gas production, mining, or farming.
- Pesticides and herbicides, which may come from a variety of sources such as agriculture, urban stormwater runoff, and residential uses.
- Organic chemical contaminants, including synthetic and volatile organic chemicals, which are by-products of industrial processes and petroleum production, and can also come from gas stations, urban stormwater runoff, and septic systems.
- Radioactive contaminants, which can be naturally occurring or be the result of oil and gas production and mining activities.
