Buyer Beware: Avoid water treatment scams

Authored on
Bloomington Briefing Published June 28, 2022
Updated on November 2, 2022

The City has been alerted to scams involving water quality in order to sell water treatment systems. Beware of false claims, deceptive sales pitches, inaccurate water quality data and scare tactics used by some water treatment companies and plumbing services to sell expensive and unnecessary home water treatment systems.

The scam typically involves a homeowner being contacted through email, letter, or phone call about free water quality testing or plumbing services. The person might say they’re calling from the state or the county or they may be an actual plumber. Once they are in your home, they will conduct a water test that will indicate the water quality is questionable. The person will then begin a hard sell of a water softener or purification system at an excessive cost to the homeowner. Follow these tips to avoid being misled:

  • If a company claims it is working with the city or a state agency, ask for the person’s name, the name of that agency, and follow up with that agency.
  • Learn about the City’s water quality by reading the annual Water Quality Report at
  • Don’t do business with door-to-door or telephone salespeople who claim your water quality is bad or want you to pay in advance.

Bloomington follows all federal and state standards for water quality and monitors our system on a regular basis to ensure high quality drinking water. If you believe you have been provided false or misleading information or subjected to unfair or high-pressure tactics during a sales visit, contact the Minnesota Attorney General’s office Consumer Complaints division at 651-296-3353, or report a fraud at
