Testing Parameters

1. Water and waste water analysis

Raw and treated water from various sources are analysed as per various specifications to assess suitability of water for specific end uses viz. Domestic, Irrigation, Construction, Potable, Recreation and Industrial Applications, analysed as per APHA’s, BIS’s and WHO’s
 
Domestic and trade waste for conformity to relevant standards for discharging into inland surface water, public sewers or non-land for irrigation purposes as desired by Pollution Control Boards
