Moline Police Warn Residents About Door-to-Door Water Test Scam

Residents in East Moline are being urged to stay alert after local police warned about a possible scam involving people going door-to-door offering to test water quality.

The warning was posted by the East Moline Police Department on Facebook after reports that individuals may be trying to schedule water tests at homes and then sell expensive water treatment systems.

Below is what residents should know about the situation and how these scams typically work.

East Moline Police Issue Scam Alert

According to the post from the East Moline Police Department, the activity has not been approved by the city.

In the Facebook alert, the department warned:

“It has come to our attention there is a potential scam of people going around the area setting up appointments to test water quality at residences in the city and then trying to sell them water quality improvement systems.”

Police say there are no approved solicitation permits for this activity in the city. That means anyone going door-to-door offering water testing services is not working for the City of East Moline.

Authorities are asking residents to turn these individuals away and contact police if someone approaches them with this offer.

Officials say the goal is to identify who is behind the activity and stop it before residents are pressured into buying expensive systems.

How Door-to-Door Water Test Scams Work

Door-to-door water testing scams are not new. Similar schemes have been reported in communities across the country, including parts of Illinois.

In many cases, salespeople offer a “free” water test and then claim the results show contamination or dangerous chemicals in the home’s water supply. They then pressure homeowners to purchase expensive filtration systems or purification equipment.

Some scammers even perform demonstrations using chemicals or tablets that make the water change color, creating the appearance of contamination—even if the water is safe.

Officials say the tactic is designed to create fear and push homeowners into quick decisions.

Reports in other Illinois communities show scammers attempting to sell systems costing thousands of dollars after claiming water quality problems that don’t actually exist.

What Residents Should Do

Police recommend taking these steps if someone comes to your door about water testing:

• Do not schedule a test from someone who appears unannounced.
• Ask for identification and permits for any door-to-door solicitation.
• Do not allow strangers inside your home for testing.
• Contact local authorities if something seems suspicious.

If you are concerned about your water quality, experts say the safest option is to have it tested through certified laboratories or trusted professionals, not door-to-door solicitors.

For now, East Moline police are asking residents to stay cautious and report any suspicious activity so the situation can be investigated quickly.
