Student Housing Water Quality Report
Safe, Tested Drinking Water for Students Living on Campus
This report provides a summary of the drinking water quality for the Glen Oaks Community College Dorms for the 2025 calendar year. It includes information about where your water comes from, how it is tested, what it contains, and how it compares to standards set by the U.S. Environmental Protection Agency (EPA) and the State of Michigan. Water Supply Serial Number: 2657
Glen Oaks is committed to providing safe, high-quality drinking water for students living on campus.
Where Your Water Comes From
The dorm water supply comes from:
- Two groundwater wells
- Each well is more than 138 feet deep
Groundwater is naturally filtered as it moves through soil and rock. There are no significant sources of contamination in our water supply area.
To protect our water sources:
- Our wells have no Maximum Contaminant Level violations.
- Well construction meets all required standards.
- No potential contamination sources are located within the required isolation area.
How We Test Our Water
The State of Michigan and the U.S. EPA require regular testing to ensure water safety. Glen Oaks met all monitoring and reporting requirements for 2025.
Contaminants and their presence in water: Drinking water, including bottled water, may contain small amounts of contaminants. The presence of contaminants does not necessarily indicate a health risk. For more information, contact the U.S. EPA Safe Drinking Water Hotline at (800-426-4791).
Vulnerability of sub-populations: 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 systems 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. U.S. EPA/Center 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 (800-426-4791).
Sources of drinking water: The sources of drinking water (both tap water and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. Our water comes from 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:
• 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
and residential uses.
• Radioactive contaminants, which can be naturally occurring or be the result of oil
and gas production and mining activities.
• 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.
2025 Water Quality Data
The table below lists regulated contaminants detected during the 2025 calendar year.
Terms and abbreviations used below:
- Maximum Contaminant Level Goal (MCLG): 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.
- Maximum Contaminant Level (MCL): 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.
- N/A: Not applicable
- ND: not detectable at testing limit
- ppm: parts per million or milligrams per liter
- ppb: parts per billion or micrograms per liter
- ppt: parts per trillion or nanograms per liter
- pCi/l: picocuries per liter (a measure of radioactivity)
- Action Level (AL): The concentration of a contaminant which, if exceeded, triggers treatment or other requirements that a water system must follow.
- Level 1 Assessment: A study of the water supply to identify potential problems and determine (if possible) why total coliform bacteria have been found in our water system.
- Level 2 Assessment: A very detailed study of the water system to identify potential problems and determine (if possible) why an E. coli MCL violation has occurred and/or why total coliform bacteria have been found in our water system on multiple occasions
Unless otherwise noted, results reflect testing conducted between January 1 and December 31, 2025.

*Ninety percent of samples collected were at or below the level shown.
Information about lead: Lead can cause serious health effects in people of all ages, especially pregnant people, infants (both formula-fed and breastfed), and young children. Lead in drinking water is primarily from materials and parts used in service lines and in home plumbing. ÌÇÐÄVlog is responsible for providing high quality drinking water and removing lead pipes but cannot control the variety of materials used in the plumbing in your home. Because lead levels may vary over time, lead exposure is possible even when your tap sampling results do not detect lead at one point in time. You can help protect yourself and your family by identifying and removing lead materials within your home plumbing and taking steps to reduce your family's risk. Using a filter, certified by an American National Standards Institute accredited certifier to reduce lead, is effective in reducing lead exposures. Follow the instructions provided with the filter to ensure the filter is used properly. Use only cold water for drinking, cooking, and making baby formula. Boiling water does not remove lead from water. Before using tap water for drinking, cooking, or making baby formula, flush your pipes for several minutes. You can do this by running your tap, taking a shower, doing laundry or a load of dishes. If you have a lead service line or galvanized requiring replacement service line, you may need to flush your pipes 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 water and wish to have your water tested, contact Glen Oaks Community College, Larry Diekman at (269)294-4312 for available resources. Information on lead in drinking water, testing methods, and steps you can take to minimize exposure is available at .
Copper is an essential nutrient, but some people who drink water containing copper in excess of the action level over a relatively short amount of time could experience gastrointestinal distress. Some people who drink water containing copper in excess of the action level over many years could suffer liver or kidney damage. People with Wilson’s Disease should consult their personal doctor.
Nitrate in drinking water at levels above 10 ppm is a health risk for infants of less than six months of age. High nitrate levels in drinking water can cause blue baby syndrome. Nitrate levels may rise quickly for short periods of time because of rainfall or agricultural activity. If you are caring for an infant, you should ask for advice from your health care provider.
