Well Water Wise (3W) Week | May 1-5, 2023

The Anoka County Public Health and Environmental Services (PHES) Department, in cooperation with 15 municipalities and county agencies, is sponsoring the 21st annual Well Water Wise (3W) week promotion May 1-5, 2023 to encourage residents to check the safety of their private well water. For information on private well testing go to the Anoka County Environmental Services Well Water Testing webpage or call 763-324-4260. County residents may pick up a well water test kit at participating city and township offices (listed below) or from Environmental Services, Suite 600 of the Anoka County Government Center, 2100 3rd Avenue in Anoka. Samples are collected by the residents and then dropped off at the Environmental Services desk in Anoka County Government Center. Water samples can be submitted to the county’s Environmental Services Unit for analysis every Monday from 8 a.m. to 4:15 p.m. and Tuesday from 8 a.m. to noon. However we will be accepting submissions every day of the week for Well Water Wise Week!

DURING 3W WEEK, samples can be submitted Monday through Thursday (8 a.m. to 4:15 p.m.) and Friday (before 11:30 AM). The well water testing kit includes details about water collection and submission. A laboratory fee of $35.00 will be charged for coliform bacteria and nitrate-nitrogen analysis.

Unlike public water utilities, private well water is not treated with chlorine to prevent bacteria growth. Simply looking at the appearance of drinking water is not a reliable indicator of whether it is safe to drink. An annual coliform bacteria test is a good way to ensure that your drinking water continues to be free of bacteria. Nitrate-nitrogen occurs naturally in groundwater and wells at concentrations below one milligram per liter (mg/L). Nitrogen can seep into private wells from a variety of sources including septic systems, nitrogen fertilizers, animal feedlots, and landfills. The Minnesota Department of Health has established a Health Risk Limit (HRL) for nitrate-nitrogen at 10 mg/L. Levels above that point may pose an immediate risk to infants and pregnant women. The testing of private wells used for drinking water is the responsibility of individual owners. There are an estimated 25,000 private wells in service throughout Anoka County. Only a small percentage of them are tested annually. For more information about well water testing, call the Environmental Services Unit at 763-324-4260.
