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 2022 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.

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 2022.

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 or visit https://www.epa.gov/ground-water-and-drinking-water.

Some individuals, including infants, older adults, and people with weakened immune systems, may be more vulnerable to contaminants. These individuals should consult their healthcare provider regarding drinking water safety.


2022 Water Quality Data

The table below lists regulated contaminants detected during the 2022 calendar year.

Unless otherwise noted, results reflect testing conducted between January 1 and December 31, 2022.

Regulated Contaminants

Contaminant MCL MCLG Level Detected Range Year Violation Typical Source
Nitrate (ppm) 10 10 7.7 1.4–14 2022 No Runoff from fertilizer; septic systems; natural deposits
Fluoride (ppm) 4 4 0.15 ND–0.15 2022 No Natural deposits; water additive; fertilizer discharge
Sodium (ppm)* N/A N/A 160 8–160 2022 No Natural deposits
Alpha Emitters (pCi/L) 15 0 2.2 ±1.9 N/A 2017 No Natural deposits
Combined Radium (pCi/L) 5 0 0.80 ±0.54 N/A 2017 No Natural deposits
Total Coliform TT N/A N/A N/A 2022 Yes Naturally present in environment

*Note: Sodium is not a regulated contaminant.

Nitrate levels above 10 ppm are a health risk for infants under six months of age. If caring for an infant, consult your healthcare provider.


PFAS (Per- and Polyfluoroalkyl Substances)

Contaminant MCL (ppt) Level Detected Year Violation
HFPO-DA (GenX) 370 <2.0 2022 No
PFBS 420 <2.0 2022 No
PFHxS 51 <2.0 2022 No
PFHxA 400,000 <2.0 2022 No
PFNA 6 <2.0 2022 No
PFOS 16 <2.0 2022 No
PFOA 8 <2.0 2022 No

All PFAS results were below the state’s Maximum Contaminant Levels.


Lead and Copper (Action Level Monitoring)

Contaminant Action Level MCLG 90th Percentile Result Range Samples Above AL Year
Lead (ppb) 15 0 0 0–0 0 2022
Copper (ppm) 1.3 1.3 0.1 0.0–0.1 0 2022

Ninety percent of samples collected were at or below the level shown.

Information about 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. Glen Oaks Community College Dorm 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 lead service line 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 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 https://www.epa.gov/ground-water-and-drinking-water/basic-information-about-lead-drinking-water.

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.

During the past year we were required to conduct 1 Level 1 Assessment(s). 1 Level 1 Assessment(s) were completed. In addition, we were required to take 1 corrective action and we completed 1 of these actions.

During the past year 1 Level 2 Assessments were required to be completed for our water supply. 1 Level 2 Assessments were completed. In addition, we were required to take 2 corrective actions and we completed of these actions.

Coliforms are bacteria that are naturally present in the environment and are used as an indicator that other, potentially harmful, waterborne pathogens may be present or that a potential pathway exists through which contamination may enter the drinking water distribution system. We found coliforms, indicating the need to look for potential problems in water treatment or distribution. When this occurs, we are required to conduct assessment(s) to identify problems and to correct the problems that were found during these assessments.

On the 2021 Consumer Confident Report there was missing verbiage regarding nitrate level above 5 ppm but below 10 ppm. A revised version was submitted.

Monitoring and Reporting to the Department of Environment, Great Lakes, and Energy (EGLE) Requirements: The State of Michigan and the U.S. EPA require us to test our water on a regular basis to ensure its safety. We met all the monitoring and reporting requirements for 2022.

We will update this report annually and will keep you informed of any problems that may occur throughout the year, as they happen. Copies are available at the building and grounds office located at 62237 Shimmel Rd. Centreville Ml. This report will not be sent to you.

We invite public participation in decisions that affect drinking water quality.
