What are the parameters of drinking water quality?

Sl. No. Parameters Drinking Water IS: 10500 – 1991
3. Taste Agreeable
4. Turbidity 5
5. pH value 6.5 to 8.5
6. Total hardness (as CaCO3) 300

How do you analyze water quality?

Chemical analysis includes the on-site analysis (pH, turbidity, and conductivity) and in-laboratory analysis (TDS and TSS).

  1. pH. pH is classed as one of the most important water quality parameters.
  2. Electrical Conductivity.
  3. Turbidity.
  4. Total Suspended Solids (TSS)
  5. Total Dissolved Solids (TDS)

How can you identify water that is safe for drinking?

Water that’s safe to drink should ideally be clear with no odor or funny taste. One way to tell if water is contaminated is to look for turbidity, or cloudiness. While cloudy water isn’t necessarily dangerous to your health, it could signal the presence of unsafe pathogens or chemicals.

How is Wqi calculated?

The WQI is calculated by averaging the individual index values of some or all of the parameters within five water quality parameter categories:

  1. Water clarity: turbidity (NTU*) and/or Secchi disk depth (meters or feet);
  2. Dissolved oxygen: Dissolved oxygen concentration (mg/l);

Who BIS standards for drinking water?

Getting clean and safe drinking water is the right of every citizen….BIS Standards Set for drinking water quality.

Test parameter Acceptable limit Permissible limit (In the absence of alternate source of water)
pH value 6.5-8.5 No relaxation
Turbidity 1 5
Total hardness as CaCo3, mg/l, Max 200 600

What are the objectives of water analysis?

The objective of water quality monitoring is to obtain quantitative information on the physical, chemical, and biological characteristics of water via statistical sampling (Sanders et al. 1987). The type of information sought depends on the objectives of the monitoring programme.

How are standard methods for drinking water analysis used?

Standard methods for drinking-water analysis should be tested under local con-ditions for accuracy and precision, agreed at national level, and applied univer-sally by both water-supply and regulatory agencies. However, the use of standardmethods does not in itself ensure that reliable and accurate results will beobtained.

Why are water samples taken at the point of use?

One objective of surveillance is to assess the quality of the water supplied by the supply agency and of that at the point of use, so that samples of both should be taken. Any significant difference between the two has important implications for remedial strategies.

How does industrial waste affect river water quality?

Effects of industrial wastes, municipal sewage, and agricultural runoff on river water quality have been investigated. The study was conducted within the Chattak to Sunamganj portion of Surma River, which is significant due to the presence of two major industries-a paper mill and a cement factory.

What should be the time between water sampling and analysis?

In general, the time between sampling and analysis should be kept to a minimum. Storage in glass or polyethylene bottles at a low temperature (e.g. 4 °C) in the dark is recommended. Sample bottles must be clean but need not be sterile. Special preservatives may be required for some analytes.
