Site Conditions, Weather Conditions, or Failing Neighboring Septic Systems or Plumbing Can Produce Local Sewer Gas Odors

Watch out: Because sewer gas contains methane gas (CH4) there is a risk of an explosion hazard or even fatal asphyxiation.

Sewer gases also will typically contain HYDROGEN SULFIDE GAS (H2S). In addition some writers opine that there are possible health hazards from sewer gas exposure, such as a bacterial infection of the sinuses (which can occur due to any sinus irritation).

Depending on the sewer gas source and other factors such as humidity and building and weather conditions, mold spores may also be present in sewer gases.

Also see SEWER GAS ODORS in COLD / WET WEATHER for additional odor tracing and cure advice for odors occurring during wet or cold weather.
