Urine and feces because bacteria populations are found in those substances. meaning if too much bacteria is found in the water it will be reductionof amount of dissolved oxygen in the water.

dirty and unsafe
It is certainly unsafe.
(previous answer)"228 ppm of natural gas is not unsafe as long as there is no way for it to increase in concentration. 5000ppm in a confined space is considered explosive. Since 5000ppm is considered the lower explosive limit of natural gas, it is reasonable to assume that enough oxygen has been displaced to possibly cause asphyxiation."(improvement:)As a 33-year veteran HVAC contractor and Gas Fitter instructor, I believe that even 1 ppm of combustible gas is unsafe. The reason is that I have seen "safe" (low-level) gas leaks blossom to hazardous conditions within 1 hour. You cannot assume that 228 ppm of natural gas will remain at that level.Also, the lower explosive limit of natural gas is 4%, which converts to 40,000 ppm.
Cholera is the most deadly disease you can get from drinking unsafe water.

Famines in themselves do not cause disease; they cause malnutrition, which is a preventable condition that can be considered as a disease. There are other diseases that are common in areas where there are famines and most of these have to do with sanitation. The leading killer in the world is cholera which is from drinking unsafe water.
NO. If you count death as being detoxified, then yes.
