An Indian pollution regulator has alleged wastewater discharged from a Tata components factory for Apple's iPhone has contaminated the groundwater for nearby farms and warned of a ‌forced shutdown unless Tata gives a satisfactory explanation. India's Tata Electronics is central to Apple's push to diversify iPhone production ‌beyond China and is the second-biggest supplier to Apple in South Asia after Taiwan's Foxconn. The Tata plant under investigation is in Hosur in southern Tamil Nadu state ​and makes back panels and other components for iPhones.
