I smell what seems to be sewage treatment chemicals coming from one toilet and sink area.This does not smell like sewage. It smells like treatment CHEMICALS. I used to live near a sewage treatment plant. I know the smell.I've been told that my home is ''at the end of the line'' whatever that means, and my doctor has been concerned that I have been exposed to some type of chemicals. Blood tests Have been ordered. Any Ideas? By the way this is a trailer in a very old trailer park, and the bath is at the end (rear) of the trailer only. Thanks.

Hard for us to diagnois but maybe your parks main drain is clogging and the neighbors are trying chemicals which could back up to your end. Have you asked the local neighbors if they are having any drain issues?

I would contact The Health Department and get them involved. Please keep us informed about the outcome. Good luck, Tom
