The Tamil Nadu Pollution Control Board has concluded its inquiry into the Tata Electronics manufacturing site in Hosur after the company responded to concerns outlined in an official warning notice, the board confirmed to Reuters.
In a formal statement, the pollution authority said Tata Electronics "has satisfactorily addressed all queries mentioned" in the notice and that it has "dropped any further course of action on this issue." The company said the board's own analysis of recently collected water samples from the Hosur facility did not indicate contamination.
The Hosur plant, located roughly 25 miles south of Bengaluru, produces back panels and other components used in iPhones. Tata Electronics is identified in the market as a supplier contributing to Apple Inc.'s efforts to broaden iPhone production outside China.
As part of its response to the pollution board, Tata Electronics commissioned an independent assessment by an accredited laboratory. The company said that analysis showed all measured parameters fell within prescribed limits, and those results were submitted to the pollution authority with its formal reply.
The investigation had been launched after farmers filed complaints alleging environmental harm. The pollution control body previously reported that Tata had discharged wastewater into a rainwater harvesting pond inside the manufacturing complex. That pond reportedly overflowed and, according to the authority, contaminated groundwater in open wells on neighboring agricultural lands.
With the pollution board indicating it will not pursue further action, Tata Electronics' responses and test data appear to have resolved the immediate regulatory concerns. The company provided the independent lab findings to support its position and to address the queries raised by the agency's warning notice.
While the pollution panel's statement notes the absence of contamination in its recent samples, the earlier allegations that prompted the probe centered on wastewater discharge into an on-site rainwater harvesting feature and subsequent groundwater impact on adjacent fields. The complaint-driven inquiry ultimately concluded after the regulator was satisfied with the supplier's documentation and remedial responses.
Summary: Tamil Nadu's pollution regulator closed its probe into Tata Electronics' Hosur facility after both the board's sample analysis and an independent laboratory's tests indicated no contamination, following farmer complaints about wastewater overflowing from an on-site rainwater harvesting pond and affecting nearby agricultural wells.
