Sewer Odors in Bathroom. DEAR TIM: We recently have begun to notice a sewer odor from only one of the three bathrooms in our house. It might be the toilet, but it's hard to tell. The smell is not constant and some times it is very strong. Everything in the house drains fine, including the toilet with the odor.
The mixture of chemicals like bleach and ammonia in landfills can produce toxic gases and odor that can significantly impact the quality of air in the vicinity of the landfill. Hydrogen sulphide produced in landfills smells similar to rotten eggs. Landfill gases do not remain on-site.
