Biohazards make up 25% of SERVPRO of Renton's jobs. This crawlspace is from a residential house whose sewer pipe busted and caused standing "black water" in their crawlspace. The household members complained of a horrible smell that they couldn't find where it was coming from.
"Black water" may contain sewage and unsafe chemicals that you and your family members should not try to clean up without professional help.
