Environmental Monitoring, Water and Air Testing Laboratory

Water testing laboratory

Our NABL-accredited water testing laboratory analyses drinking water, groundwater, surface water, effluent and treated effluent against CPCB and SPCB norms. Samples can be collected by our team or submitted directly.

Typical water quality parameters tested:

• Physical - pH, colour, odour, turbidity, temperature, total dissolved solids (TDS), total suspended solids (TSS)
• Organic load - biochemical oxygen demand (BOD), chemical oxygen demand (COD), oil and grease
• Chemical - hardness, alkalinity, chlorides, sulphates, nitrates, fluorides, phosphates, residual chlorine
• Heavy metals - lead, chromium, cadmium, arsenic, mercury, iron, zinc, copper, nickel
• Microbiological - total coliform, faecal coliform, E. coli, total plate count

Air quality monitoring

• Ambient air - PM2.5, PM10, SO₂, NO_x, CO, ozone, ammonia, lead, benzene
• Stack emissions - particulate matter, SO₂, NO_x, CO, HCl, volatile organic compounds
• Workplace air - respirable dust and specific chemical exposures

Noise and soil

• Noise - ambient and workplace levels in dB(A), measured day and night against the applicable standards
• Soil - pH, organic carbon, nutrients, heavy metals and contamination screening

Monitoring data feeds directly into statutory returns and the annual Form-V Environmental Statement, and into environmental audits. Gaps in monitoring cannot be filled retrospectively, which is why we work to a fixed calendar.
