In my own research, I found that home testing was not always great. If you wanted an accurate and broad test, you had to send samples out to a lab. It wasn't massively expensive ($50-100), but it was close enough to the cost of a filtration system that it's probably not worth it for an individual. If you want to do it for your town, that's great! Perhaps your local news station would be interested, too.
