Sewage Contamination Testing
Sewage or fecal contamination of indoor environments poses a serious health risk, as feces are reservoirs for enteric pathogens. These pathogens are normally transmitted by the fecal-oral route and infect the gastrointestinal tract. However, when sewage contamination occurs, these pathogens, along with other intestinal organisms, may also be transmitted through air, water, and food.
AEMTEK offers a complete line of microbial laboratory testing. Testing for sewage screen and/or sewage contamination in indoor environments is performed following EPA or California Water Board recommendations for water testing. Samples from indoor environments such as water, air, surface (swab), or bulk (carpets, wood, furniture, etc.) can be tested for the indicator bacteria (see Aemtek Micro Examiner, April 2005) to assess possible sewage contamination. Indicator tests include:
- Total coliforms
- E. coli
- Microbial contamination source tracking
The presence or absence of the indicator bacteria will aid the investigator in confirming or “rejecting” the presence of fecal contamination.
