I found a company that will do a follow up test to identify the type of coliform for $50, so we will see what that turns up in about a week or so!

The original test 6 months ago did have those steps taken, but great info!

Thank you!

Thanks! However, all I’ve found online are home tests that test for if coliform is present (which we know it is), but not how many colonies (which would indicate the problem has gotten worse).

I’ve reached out to the testing company our commercial kitchen uses but those tests are over $100, which feels wrong for us to foot ourselves based on principle.

Do you have any tips on which tests?

All I could find in the state laws was that a landlord has to notify you of coliform levels, but nothing about rectifying it:

The landlord or building manager of a dwelling that is rented for human habitation and for which the water supply is a residential private drinking water well shall obtain a water test every 3 to 5 years for the contaminants specified pursuant to section 2660-T and shall disclose the results of the water test to each tenant of the dwelling within 10 business days after receiving the results from a laboratory. The landlord or building manager shall allow each prospective tenant of the dwelling to review results of the most recent water test prior to signing a lease or moving into the dwelling.
