2018 Water Quality Report


This report covers the drinking water quality for the Charlevoix Township Water System for calendar year 2018. This information is a snapshot of the quality of the water that we provided to you in 2018. Included are details about where your water comes from, what it contains, and how it compares to Environmental Protection Agency (EPA) and the Michigan Department of Environmental Quality (MDEQ) standards.

Your water comes from eleven groundwater wells of varied depth within the Lake Michigan watershed, at five different locations. An updated source water assessment for our system was completed by the State in 2016 to determine the susceptibility or the relative potential of contamination. The susceptibility rating is on a seven- tiered scale from “very-low” to “very-high” based primarily on geologic sensitivity, water chemistry and contaminant sources. The susceptibility of our source is low to moderately low. There are no significant potential sources of contamination within the isolation area. We are making efforts to protect our source through a program of routine inspection and maintenance.

If you would like to know more about these reports, please contact Mr. Chuck Center, the township supervisor.

  • Contaminants and their presence in 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 (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. 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).
  • 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.


In order to ensure that tap water is safe to drink, EPA and MDEQ prescribe regulations that limit the amount of certain contaminants in water provided by public water systems. Food and Drug Administration regulations establish limits for contaminants in bottled water which provide the same protection for public health.



2018 Water Quality Data

The table below lists all the drinking water contaminants that we detected during the 2018 calendar year. The presence of these contaminants in the water does not necessarily indicate that the water poses a health risk. Unless otherwise noted, the data presented in this table is from testing done January 1 – December 31, 2017. 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.

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.
  • Maximum Residual Disinfectant Level (MRDL): The highest level of a disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants.
  • Maximum Residual Disinfectant Level Goal (MRDLG): 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 disinfectants to control microbial contaminants.
  • Treatment Technique (TT): A required process intended to reduce the level of a contaminant in drinking water.
  • N/A: Not applicable
  • ND: not detectable at testing limit
  • ppb: parts per billion or micrograms per liter
  • ppm: parts per million or milligrams 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.


Samples Collected at Charlevoix Township

¹ Sodium is not a regulated contaminant.
² The chlorine “Level Detected” was calculated using a running annual average.


³ Ninety (90) percent of the samples collected were at or below the level reported for our water.




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. Charlevoix Township 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 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.



Monitoring and Reporting to the Department of Environmental Quality (DEQ) 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 2018.

We will update this report annually and will keep you informed of any problems that may occur throughout the year, as they happen. Copies of this report are available at the Township Office, by contacting at (231) 547-4611 or online at www.charlevoixtwp.com/water/.

We invite public participation in decisions that affect drinking water quality. Questions and/or concerns regarding your water supply may be addressed during any regular Township board meeting, held on the second Monday of the month at 7pm. For more information about your water, or the contents of this report, you may also contact your system operator, Aaron Nordman at (231) 547-2121. For more information about safe drinking water, visit the U.S. Environmental Protection Agency at www.epa.gov/safewater/.
