What should be the parameters of drinking water?

A number of parameters such as pH, turbidity, conductivity, total suspended solids (TSS), total dissolved solids (TDS), and heavy metals such as Cu, Zn, Mg, Fe, Cd, Pb, Cr, As, Hg, and Sn were analysed for each water sample collected during winter and summer periods.

What is permissible limit?

Permissible exposure limit (PEL) is a regulatory limit on the amount or concentration of a substance in the air. This is usually based on an eight-hour time weighted average (TWA), although some are based on short-term exposure limits (STEL). Workplace environmental exposure limit (WEEL) may be expressed as TWA.

What are the 6 main indicators of water quality?

Water Quality Indicators

  • Temperature and dissolved oxygen.
  • Conventional variables (pH, total dissolved solids, conductivity, and suspended sediment)
  • Nutrients.
  • Metals.
  • Hydrocarbons.
  • Industrial Chemicals (PCBs and dioxins/furans)

What are the five qualities of water?

Physical characteristics of water (temperature, colour, taste, odour and etc.) are determined by senses of touch, sight, smell and taste. For example temperature by touch, colour, floating debris, turbidity and suspended solids by sight, and taste and odour by smell.
