Water, Waste Water and Effluents


Accurate Water Analysis is a responsibility to the Country’s Infrastructure. According to estimates, approximately 71% of the Earth’s surface is covered with water. The total amount of water on the earth is about 1.36 billion cubic kilo metres (326 million cubic miles). However, only 2.5% of the Earth’s water is fresh water, of this 98.8% is in the form of ice and ground water, leaving a very low volume for the consumer. Thus, water is the most precious resource.

Testing the suitability of water for the intended use requires adequate expertise and sophisticated instrumentation. What to test for and how frequently is outlined in various documents .

The essential routine parameters for basic potable water quality control are pH, TDS (Total Dissolved Solids) Calcium and Magnesium Hardness (as CaCo3) Alkalinity, Fluoride, Chloride, Sulphate, Nitrate, Arsenic, Dissolved Iron, Salinity, Total Coliforms and E.coli.

Bombay Test House has more than a decade experience in testing water samples for various purposes and specifications.

We undertake the testing for Water as per the standards given below:


  • Packaged drinking water - IS : 14543 - 2004
  • Natural mineral water - IS : 13428 - 2005
  • Surface/ground water - IS : 10500 - 1991
  • Feed water/boiler water - IS : 10496 - 1983
  • Water for Food processing industry as per IS: 4251 - 1967
  • Water for Storage batteries as per IS: 1069 - 1993
  • Drinking water as per WHO/EPA/European community specification
  • Purified water and water for injection (as per EP, BP   USP)
  • Water for Irrigation purpose as per IS:11624-1986
  • Water for swimming pools IS: 3328-1993
  • Water for Paper & Pulp industries IS: 2724

Waste Water

The two most common tests for waste water are BOD (Biochemical Oxygen Demand) and COD (Chemical Oxygen Demand) determinations. BOD is an expression for the quantity of oxygen required for biological degradation of Organic matter in a wastewater sample. BOD measurement is therefore used as a basis for the detection of biologically degradable organic matter in water.

Analysis of Waste Water and Effluents

  • As Per MOEF guidelines
  • AS per BIS specifications
  • As per State Pollution Control Boards
  • Heavy Metals and Pesticides Residues
  • Poly-nuclear Aromatic Hydrocarbons (PAHs)
  • Polychlorinated Biphenyls (PCBs)
  • Volatile Organic Compounds (VOCs)
