I got the following e-mail from somebody who wanted to know if either anybody knows about the situation he describes or Walpole/Norwood forums to which he could post. If you know about either, post here or mail me and I'll forward:
I am looking at a house in Walpole that is right off Pleasant St On Pleasant St. about a quarter mile from the house is this huge plant! it used to be Bird Shingles Co., now it is Certainteed shingles? We are afraid to buy and then find out it's a cancer neighborhood. I know most towns in Mass. have some old plants that used to dump wherever they wanted but this place kind of scares me. The realtor was like "oh it's no big deal don't worry about it," we LOVE the house but we don't love cancer. Any info would be greatly appreciated.
