Well I called the health dept. Could'nt get a hold of Kevin H. but did talk to another guy and he said we should be o.k. He did suggest taking water samples and have them analyzed before and after the septic is being used. The house won't be finished for a few months yet. So I'll get the vials from them this week and send them off to the lab. Then next spring will get some more samples and compare results. Keeping my fingers crossed!!!!
