Water Quality Testing
Drinking, packaged, ground, surface, process and waste water tested against IS 10500, IS 14543, IS 13428 and CPCB discharge norms.
Water Testing at CVR Labs
CVR Labs is NABL-accredited and BIS- and CPCB-recognised for water testing. We run the complete physico-chemical, heavy-metal, organic and microbiological panels defined by the applicable Indian Standard, comparing every result against acceptable and permissible limits.
Using GC-MS/MS, LC-MS/MS, ICP-MS, ICP-OES, HPLC, AAS, GC, IC and UV-Vis alongside classical wet-chemistry and membrane-filtration microbiology, our analysts deliver reports that support drinking-water safety verification, BIS certification, factory licensing and pollution-control-board consent compliance. Sampling support and guidance are available on request.

Why this testing matters
Public Health
Unsafe water transmits chemical and microbial disease. IS 10500 and IS 14543 define the limits that protect water consumers.
Statutory Compliance
CPCB / TNPCB consent conditions, BIS certification and factory licensing all require periodic accredited water analysis.
Process Protection
Scaling, corrosion and fouling from out-of-spec process and boiler water cause costly downtime and equipment failure.
Discharge Compliance
Effluent must meet CPCB/TNPCB discharge standards before release. Accredited BOD/COD data is mandatory for environmental clearance.
