Environmental Monitoring
CPCB-recognised stack emission, ambient & indoor air, soil, sludge, hazardous waste and used-oil monitoring for regulatory compliance.
Environmental Monitoring at CVR Labs
As a CPCB-recognised environmental laboratory (recognised under the Environment (Protection) Act, 1986) and NABL-accredited testing facility, CVR Labs delivers environmental monitoring to the standards required by CPCB and State Pollution Control Boards.
Field sampling, on-site measurement and laboratory analysis follow CPCB and IS methods, using calibrated equipment and GC-MS/MS, LC-MS/MS, ICP-MS, ICP-OES, HPLC, AAS, GC, IC and UV-Vis. The resulting data is formatted for consent-to-operate, environmental-clearance compliance and statutory reporting, and is backed by approved Government Analysts.
Services in this category
Stack Emission Monitoring
Isokinetic stack sampling for PM, SO2, NOx, CO, metals and acid gases to CPCB norms.
Ambient Air Quality Monitoring
NAAQS-compliant measurement of PM10, PM2.5, SO2, NOx, CO, ozone, lead and metals.
Indoor Air Quality Testing
Work-environment and indoor air assessment – dust, gases, VOCs, CO2 and thermal comfort.
VOC Monitoring
Speciated volatile organic compound and compressed-gas analysis by GC-MS.
Soil Testing
Agricultural fertility and contaminated-land assessment – nutrients, heavy metals and organics.
Sludge & Sediment Analysis
Characterisation of ETP/STP sludge and sediments for metals, nutrients and disposal compliance.
Hazardous & Solid Waste (TCLP)
TCLP leachate, calorific value and hazardous-characteristic testing for waste classification.
Used / Waste Oil Testing
Used-oil characterisation – metals, PCBs, flash point and recyclability per Hazardous Waste Rules.
What we analyse
Source / Stack Emission
Iso-kinetic stack sampling of particulate and gases per CPCB.
Ambient & Indoor Air
NAAQS and workplace air-quality parameters.
Soil & Solid Waste
Fertility, contamination and TCLP characterisation.
Water & Effluent
Discharge-compliance parameters per CPCB / TNPCB.
Why this testing matters
Regulatory Mandate
CPCB and State Pollution Control Boards require periodic stack, ambient air, soil and waste monitoring as a condition of operating consent.
Worker & Public Health
Airborne particulates, gases and VOCs damage health. Monitoring verifies that controls keep exposures within statutory limits.
Consent & Clearance
Consent-to-operate, environmental clearance and EC compliance reports all depend on data from a CPCB-recognised laboratory.
Liability Shield
Documented, accredited environmental data is your primary defence in inspections, audits and pollution disputes.

Where these results are used
Environment (Protection) Act, 1986
The umbrella legislation under which CPCB recognises environmental laboratories and sets monitoring requirements.
Air & Water Acts — Consent to Operate
Industries must monitor stack, ambient air and effluent as conditions of consent issued by State Pollution Control Boards.
NAAQS, 2009
National Ambient Air Quality Standards define limits for PM10, PM2.5, SO2, NOx, CO, ozone and others.
Hazardous & Other Wastes Rules, 2016
Waste must be characterised (including TCLP) and managed per the rules before disposal.
Noise Pollution Rules, 2000
Ambient and source noise must be monitored against prescribed day/night limits.
