PH Logo Well Water Testing

Does your home use well water?
Heading to the cabin this weekend?
When was the last time you had your well water tested?

Getting water tested is particularly important if you have a well in an area that has experienced flooding.
The Saint Paul - Ramsey County Public Health Laboratory offers well water testing for both home and vacation properties. 
You do not need to be a resident of Ramsey County - this service is available for anyone. 
Tests analyze the concentration of nitrate-nitrogen and the presence of coliform bacteria in drinking water. 

What tests does the lab run on water samples?

Well waters are tested for the presence of coliform bacteria and the concentration of nitrates.

What if you think your water has chemical contamination?

You will need to call a private laboratory (listed in your local yellow pages) for information and cost.

How much does the test cost?

The cost is $25.00. 
Payment is accepted as cash or check (made out to: Ramsey County Public Health) and should be dropped off with your water sample. 

What do I need to do to have my water tested?

Please call to request a sampling kit | 651.266.1321
The sampling kit (containing an information and report sheet, instructions for water collection and sterile plastic sample bag) will be mailed to you. 
We are unable to accept samples in personal containers or bags. 

Once I have collected my water sample, what do I do with it?

Water samples should be chilled immediately by placing the sealed sterile bag in a cooler (with ice) and transported to the lab as soon as possible.
Maintain the sample at refrigerator temperature and plan to arrive within 30 hours of collection.
Remember to bring your completed test request sheet and payment.

Where is the Saint Paul - Ramsey County Public Health Laboratory located?

Our lab is located downtown Saint Paul.  Between 10th and 11th, Cedar and Wabasha Street.

There is free parking in the lot and metered parking around the block.  Once inside the building, take the steps or elevator to the second floor and proceed to room 215, Patient Services.

What are the lab hours?

The Saint Paul - Ramsey County Public Health Laboratory will accept well water samples for testing on Mondays, Tuesdays and Wednesdays between 8:00 am - 4:00 pm.

When will I get the test results?

Test results will be mailed to you in approximately one week.

What will the results tell me?

The testing provides an indication of the safety of your potable water by determining the presence or absence of coliform bacteria and the level of nitrate nitrogen present. 

Please note:  Results are intended for personal use only and should only be regarded as an indication of the water quality at the time of sampling, not an overall evaluation of the entire water system. 
Any water sample collected and submitted by the owner cannot be considered an official sample and cannot be used for Veteran's Administration or FHA loan purposes.
