Drinking water quality standards describes the quality parameters set for drinking water. Water may contain many harmful constituents, yet there are no universally recognized and accepted international standards for drinking water. Even where standards do exist, the permitted concentration of individual constituents may vary by as much as ten ...
Maximum contaminant levels (MCLs) are standards that are set by the United States Environmental Protection Agency (EPA) for drinking water quality. [1] [2] An MCL is the legal threshold limit on the amount of a substance that is allowed in public water systems under the Safe Drinking Water Act (SDWA).
The alum dosage is also insufficient to cause toxicity in humans, and is often similar to alum doses used in conventional drinking water treatment. [8] To reduce negative biological effects, the accepted limit for dissolved aluminum concentrations in a water body is 50 μg Al/L and pH should be restricted to a range of 5.5-9. [2]

14] Water can be classified by the level of total dissolved solids (TDS) in the water: Fresh water: TDS is less than 1,000 ppm. Brackish water: TDS = 1,000 to 10,000 ppm. Saline water: TDS = 10,000 to 35,000 ppm. Hypersaline: TDS greater than 35,000 ppm. Drinking water generally has a TDS below 500 ppm.
