Door to door Water scam

A guy just came to my door, with a big lanyard and an ID tag and tablet, insisting that he needed to come in and test the water from my kitchen tap. He said my home had been identified as having dangerous chemicals in the water. He said he’s from some organization that started with the word California, but for the life of me, I can’t remember what the rest of the name was. He was a young guy, seemed nice enough, but was very pushy. And when I told him that no he could not come into my house and he could not test the water in my kitchen, he turned to leave and said “Fine. Enjoy your nasty chemical water then!”

I then called the city and they said it was a scam. This is just a guy trying to sell a water filter so I thought I’d spread the word.
