What is the best indicator of water quality?
The best indicator of water quality is typically the presence of bacteria such as E. coli or coliforms, as they can indicate contamination from fecal matter and other pathogens. Other important indicators include levels of dissolved oxygen, pH, temperature, turbidity, and concentrations of pollutants such as heavy metals and chemicals. Testing for these parameters can provide a comprehensive assessment of water quality.
Why is it necessary to make periodic chemical and bacteriological analysis of water used for drinking?
To detect the presence of poisionous elements such as lead and to detect if there is contamination of the water source of harmful bacteria such as E Coli
