Nitrate-nitrogen (referred to as nitrate) is a common contaminant found in many wells throughout Minnesota. Shallow wells, dug wells, and wells with damaged or leaking casings are the most vulnerable to nitrate contamination. Major sources of nitrate contamination can be from fertilizers, animal waste, and human sewage. It is highly recommended to test your drinking water supply on a regular basis.

How this works?


1. Find a clean sample container such as a plastic sandwich or freezer bag, glass jar, etc. that can hold at least 1 cup of water. Collect a water sample from your well by running the cold water tap for 5 minutes before taking the sample.


2. While the water is running, use a permanent marker to label your container with your first and last name. If you wish to remain anonymous, label the container with a number or a code you will easily remember. If you have more than one sample, add an identifier like Sample #1 and Sample #2.

3. Collect a minimum of a ½ cup of water in the container within 24 hours of arriving at the event. The water sample should be cool upon arrival so keep the sample refrigerated until you leave for the event.

4. If you have water treatment equipment installed (other than a water softener which has no effect on nitrate levels), we recommend taking a sample “before” and “after” to determine if your treatment equipment is working properly.

5. Bring your water sample to the Greenwald Pub between the hours of 2:00 and 7:00 PM on Tuesday, August 16th. The address is 310 1st Ave North, Greenwald MN.

6. Once you arrive at the event, we will ask you to fill out a short survey about your water, your well, and your water treatment system. Your sample will be transferred into one of our leakproof containers. If you can, bring a picture of your well and treatment system, it will help us advise you on water quality issues that may show up in the testing.

7. Your sample will be collected from you and analyzed while you wait – Hopefully no longer than 10 minutes. Our water experts will bring you the results and gladly answer any questions you may have about your well or well water.

8. There will be a discounted opportunity for additional certified water testing a $90.00 value for $70.00.

Can't make the event, but still interested in getting your water sampled?

More Information on Nitrates

At a minimum, private wells should be tested for coliform bacteria once a year and for nitrate every two or three years. If nitrate has been detected previously, the well should be tested for nitrate every year.

Every private well should be tested at least once to determine if arsenic is present in the water, and at what levels (language provided by the Minnesota Department of Health).
