In Nalla Cheruvu water of Domadugu colony successful Sangareddy territory wherever villagers are protesting against the contamination of the water by Hetero Drugs manufacturing unit, the Chemical Oxygen Demand (COD) roseate from 64 milligrams per litre (mg/l) successful June, 2021 to 1,676 mg/l by August, 2025. Dissolved Oxygen during the aforesaid play reduced from 5.2 mg/l to 1.2 mg/l.
COD is the measurement of the oxygen needed to chemically oxidise integrated pollutants successful water. The higher the measure, the much contamination it indicates. Dissolved oxygen measurement indicates the contrary: the higher the measure, the amended the wellness of the water.
The figures were mentioned by the Telangana Pollution Control Board (TGPCB) which issued directions to the Hetero Drugs astatine the opening of the year, directing it to get its enactment unneurotic oregon look penal action.

After the latest instance, the TGPCB issued directions to the institution seeking it to get the h2o samples analysed by IIT-Hyderabad. The survey was done by an adjunct prof from the institution’s Civil Engineering wing.
The IIT-H report, cited successful TGPCB order, concluded that the pinkish coloration is simply a grounds of terrible ecological imbalance, driven chiefly by nutrient overloading, and consequent improvement of “anoxic, microbially active” conditions. The physiochemical information shows elevated turbidity and important nutrient enrichment from nitrogen and phosphorus. Under these oxygen-poor conditions, sulfate-reducing bacteria became active, generating hydrogen sulfide and providing the chemic situation indispensable for proliferation of specialised pigmented microbial communities, the study read.
Task Force Committee of the Board, during its inspection, noted mediocre functioning of the industry’s Zero Liquid Discharge strategy and non-compliance with the consent conditions of the Board.
Chemical fingerprinting investigation of the h2o samples revealed uniformity successful the chemicals recovered successful h2o samples from the lake, stagnated h2o extracurricular the compound partition of the unit, and rainwater retention tanks of the industry, which confirms that the effluents discharged by the manufacture were the origin of contamination successful Nallakunta lake.
The committee besides noted repeated non-compliance of consent conditions and Board directions during 7 inspections implicit the past 3 years.
