I recently proved the water testing scam to my wife last year.
She made the appointment with a filter company, the gentleman showed up at our residence on-time and took two samples. 1 from my kitchen faucet and 1 from my well water. He placed them on my kitchen counter (with his back towards me) and started adding droplets of chemicals to the vials. He brought them over to me and showed me how dirty the well water is compared to the municipal water.
Then, I asked him why he didn’t place the droplets into the vials in front of me so I could see the equal amounts being placed into the vials. He come up with this bullshi+ line…“Oh, I didn’t think you wanted to see the actual testing being done”. I told him that he was at my house to perform water testing and that he didn’t think I wanted to see the actual testing. I then told him to leave, and that we were all set.
I then took a sample of my well water to my water testing lab the next day and it came out in flying colors. No negatives whatsoever.
I’ll never trust a water testing company ever again.
