Thanks Brent. I got that link from Mark Violand a few days ago and put it in our site.
Some years ago a local association supplied samples of waste tank water to a DCNR representative we knew. The guy was very fair minded and a customer of one of the members, and we thought it would be interesting to get his feedback about what exactly was in our waste water.
He came to a meeting to speak to us, and opened with:
"After reading what you extract from carpets, I'm going to have my own carpet cleaned more frequently, and make sure everyone I know gets it done, too. Your tanks were full of high amounts of herbicide, pesticide, and lead (which probably came from lead paint or outdoor pollution)."
I would have loved to have had him give us the reports and write an article, but he had to shy away from doing that, and could only talk from a personal perspective.
There is a lot of bad stuff "out there" that get's tracked "in there". Great to know that we can remove some of it, at least.
