Flooding and Sewage Damage Testing

Have you had sewage backup or flooding in your home, office or school? Are you concerned that you and others are exposed to fecal pathogens? Give Indoor Science a call at (312) 920-9393 and we can provide you with a quote for evaluating your property.


What should I do if I have flooding or a sewage back-up?

Unless the affected area is relatively small, it is recommended to hire a water damage professional to help dry and decontaminate the space. The problem is that many water damage contractors inadequately clean and decontaminate the affected area. We have seen rooms that appear to be dry and clean, but sampling reveals an entirely different picture.


Indoor Science doesn’t perform contracting work. Here is how we get involved:

  • We help in the upfront planning to develop a scope of work. When it comes to developing a scope of work, water damage contractors have a conflict of interest which may be exploited. This results in a project costing tens of thousands of dollars, when perhaps it should have only been a few hundred.
  • We oversee the drying process to make sure that key areas of the scope of work are being followed
  • We perform testing upon completion to verify that the space has been properly cleaned and decontaminated.
  • If the water is not dried promptly, we may also recommend performing a mold assessment.


What fecal pathogens are found in sewage backups and floodwaters?

Depending on the source of the floodwater and sewage, there may be whole host of fecal pathogens now present in your property. Some of the most significant fecal pathogens that might be found after sewage backup or flooding include:

  • E. coli O157:H7
  • Hepatitis A
  • Salmonella
  • Campylobacter
  • Vibrio
  • Shigella
  • Giardia
  • Cryptosporidium
  • noroviruses


The clearance testing we perform does not measure all of these fecal pathogens directly. Rather, we use indicators which are easier to measure and analyze in the laboratory.


What does it cost?

Each project is unique, especially with sewage damage.  Call us at (312) 920-9393 for a customized quote.
