Despite iPhone parts manufacturer Tata saying recent water samples collected inside its factory in Hosur, India, showed no signs of contamination, Reuters reports that local health officials are still investigating complaints from nearby farmers. Here are the details.

Tata again under scrutiny

Last month, Apple supplier Tata was warned of a possible shutdown at one of its iPhone component plants in India, after the Tamil Nadu Pollution Control Board alleged that wastewater from the facility had contaminated groundwater in adjacent farms.

Earlier this week, Tata said that the regulator had dropped further action against the plant, after the company submitted its response and addressed the issues raised in the warning notice:

On Tuesday, Tata told Reuters in a ⁠statement that the Tamil Nadu Pollution Control Board had confirmed that the company “has satisfactorily addressed all queries ​mentioned” in the warning notice and “dropped any further course of action on this issue”.
