Gilbert 2022 Drinking Water Report

Making Safe Drinking Water
Your drinking water comes from a groundwater source: three wells ranging from 87 to 89 feet deep, that draw water from the Quaternary Buried Artesian aquifer.
Gilbert works hard to provide you with safe and reliable drinking water that meets federal and state water quality requirements. The purpose of this report is to provide you with
information on your drinking water and how to protect our precious water resources.
Contact Terah Rinerson, Lead Operator, at (218) 748-2219 or if you have questions about Gilbert’s drinking water. You can also ask for information
about how you can take part in decisions that may affect water quality.
The U.S. Environmental Protection Agency sets safe drinking water standards. These standards limit the amounts of specific contaminants allowed in drinking water. This ensures
that tap water is safe to drink for most people. The U.S. Food and Drug Administration regulates the amount of certain contaminants in bottled water. Bottled water must provide
the same public health protection as public tap 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 Environmental Protection Agency’s Safe
Drinking Water Hotline at 1-800-426-4791.

Gilbert Monitoring Results
This report contains our monitoring results from January 1 to December 31, 2022.
We work with the Minnesota Department of Health to test drinking water for more than 100 contaminants. It is not unusual to detect contaminants in small amounts. No water
supply is ever completely free of contaminants. Drinking water standards protect Minnesotans from substances that may be harmful to their health.

How to Read the Water Quality Data Tables
The tables below show the contaminants we found last year or the most recent time we sampled for that contaminant. They also show the levels of those contaminants and the
Environmental Protection Agency’s limits. Substances that we tested for but did not find are not included in the tables.
We sample for some contaminants less than once a year because their levels in water are not expected to change from year to year. If we found any of these contaminants the last
time we sampled for them, we included them in the tables below with the detection date.
We may have done additional monitoring for contaminants that are not included in the Safe Drinking Water Act. To request a copy of these results, call the Minnesota Department
of Health at 651-201-4700 between 8:00 a.m. and 4:30 p.m., Monday through Friday.
Some contaminants are monitored regularly throughout the year, and rolling (or moving) annual averages are used to manage compliance. Because of this averaging, there are
times where the Range of Detected Test Results for the calendar year is lower than the Highest Average or Highest Single Test Result, because it occurred in the
previous calendar year.

• AL (Action Level): The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.
• EPA: Environmental Protection Agency
• 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.
• 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 for 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 disinfectants to control microbial contaminants.
• N/A (Not applicable): Does not apply.
• ppb (parts per billion): One part per billion in water is like one drop in one billion drops of water, or about one drop in a swimming pool. ppb is the same as micrograms per
liter (μg/l).
• ppm (parts per million): One part per million is like one drop in one million drops of water, or about one cup in a swimming pool. ppm is the same as milligrams per liter
• PWSID: Public water system identification.
