City of Coopersville Consumer Confidence Report (CCR)
for the year of 2023
Annual Drinking Water Quality Report
Prepared in conjunction with the City of Grand Rapids Water System
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 and copies of the service line material for your home or business are available by calling the Water Department at
616-997-9731 or visiting our city’s website at http://www.cityofcoopersville.com/ccr.html.
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 2023 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.
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.
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.
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:
Microbial contaminants such as viruses and bacteria, which may come from sewage treatment plants, septic systems, agriculture livestock operations, and wildlife.
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.
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.
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.
The City of Coopersville has 1435 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 of Coopersville. 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 of Coopersville will be completing a comprehensive DSMI by 2024 that will be submitted to EGLE. Under current EGLE lead and copper rules the City of Coopersville is replacing all lead service lines and Galvanized service lines, whether they are City or privately owned, during capital improvement projects in accordance with asset management planning.
To ensure tap water is safe to drink, the EPA has regulations that limit the amount of contaminants in water provided by public water systems. The table below lists the drinking water contaminants that we detected during the calendar year of this report, unless otherwise noted. Although many other contaminants were tested, only those substances listed below were found in your water. All sources of drinking water contain some naturally occurring contaminants. At low levels these substances are generally not harmful in our drinking water. Removing all contaminants would be extremely expensive, and in most cases, would not provide increased protection of public health. A few naturally occurring minerals may actually improve the taste of drinking water and have nutritional value at low levels. 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. All of the data is representative of the water quality, but some are more than one year old. In this table, you may find terms and abbreviations that might not be familiar to you. To help you better understand these terms, we have provided the definition.

Important Drinking Water Definitions & Units
- 90th Percentile: The minimum level of contamination found in the highest 10 percent of samples collected.
- AL (Action Level): The concentration of a contaminant that, if exceeded, triggers treatment or other requirements that a water system must follow.
- MCL (Maximum Contaminant Level): 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.
- MCLG (Maximum Contaminant Level Goal): 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.
- MNR: Monitored Not Regulated
- MRDL (Maximum Residual Disinfectant Level): The highest level of a disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary or control of microbial contaminants.
- MRDLG (Maximum Residual Disinfectant Level Goal): 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 disinfection to control microbial contaminants.
- NTU (Nephelometric Turbidity Units): Turbidity is a measure of the cloudiness of the water. We monitor it because it is a good indicator of the effectiveness of our filtration system.
- NA: Not applicable
- ND: Not detected
- NR: Monitoring not required but recommended
- ppm (parts per million): Number of milligrams of substance in one liter of water (mg/L)
- ppb (parts per billion): Number of micrograms of substance in one liter of water (μg/L)
- ppt (parts per trillion): Number of nanograms of substance in one liter of water (ng/L)
- TT (Treatment Technique): A required process intended to reduce the level of a contaminant in drinking water
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. This report is available. For a copy, please call our Customer Service at 311 or 616.456.3000.
Note: The data table contains the highest annual test results for all required and voluntary monitoring of regulated substances. The Grand Rapids Water System monitors many regulated and unregulated substances more frequently than required and, as a consequence, these results are included in the table. In addition to the test results listed in the table, we analyzed the water for 87 different contaminants/chemicals in 2022; none of which were found at detectable levels.
