1 When sewer gases diffuse into household air, they gradually displace oxygen and suffocate occupants. 2  The effects of oxygen deficiency include headache, nausea, dizziness and unconsciousness. 3  At very low oxygen concentrations (less than 12%), unconsciousness and death will occur quickly and without warning.
1 Increased organic matter (from the sewage) breaking down in the river reduces the amount of dissolved oxygen in the water body as the decomposition process uses up the available dissolved oxygen. 2  Fish and other aquatic life need that dissolved oxygen in the water to live.f certain bacteria are present, it can create human health issues â illness and death in the short term, or long-term effects on reproduction and other bodily processes. In the case of Canmore, the sewage was highly diluted with groundwater.
