Probably human or animal excrement !
what causes due to Chromium as a contaminant in drinking water in excess of permissible levels
The contaminant in the water supply was ammonia leaking from a storage tank. Once the contaminant is identified, likely sources for it can be checked. The experiment was ruined when a contaminant was found in the sterile solution.
Evaporated water is absolutely pure. Every contaminant is left behind.
How are water quality standards determined? Distinguish between water quality criteria pollutants and maximum contaminant levels.
yes people have died from lead intake

Oceans are formed from water; the major contaminant is sodium chloride.
i need help answering
Depends on the aspect of quality that needs to be improved. If the raw water contaminant is chemical that processes such as dissolved air flotation, absorption and sand filtration can be used. If the contaminant is organic, the above process with help also, but the addition of chlorine or other disinfectant would been needed to make the water potable.
A water filter will remove MOST contaminants. However it does not remove all contaminants from tap water. There is not a water filter out there that can remove every single contaminant from your tap water.
Salt can act as a contaminant in freshwater environments when present in high concentrations, as it can disrupt the balance of salinity in the water and harm aquatic life. Excess salt runoff from roads, mining activities, or agricultural practices can lead to contamination of waterways and impact the health of plants, animals, and humans reliant on that water source.
A contaminant is something that does not belong. Contamination is the presence of one or more contaminants.
