Groundwater up to a depth of 100 feet has been rendered unfit for human consumption due to rampant industrial pollution in Toansa village. Four major pharmaceutical factories Ranbaxy Laboratories, Montari Industries (now closed), Max India, DSM India and a paper mill in the area have poisoned ground water with their toxic wastes to such an extent that the Department of Water Supply and Sanitation in Nawan Shahar has marked its 200 hand pumps with red crosses warning people that the water from these pumps has been contaminated with hazardous chemicals.

Ratlam is an important industrial town in Madhya Pradesh with distillery, dye and pharmaceutical industries. Pollution studies conducted in the Ratlam area show that the groundwater in part of Ratlam town and about 12 villages namely Doshigem, Ghatala, Bajankhedi, Jadwasa Kala and Khurd etc., has become red in color due to discharges from Sajjan Chemicals. The groundwater in these areas is also high in salinity. Sajjan Chemicals, Jayant Vitamins, Stellar Drugs, Alcohol Plant and IPCA Laboratory have been blamed for the increased salinity although all the industries except the latter two have shut down. Shutting down the industries has not solved the pollution problem as hazardous wastes lie in the open. In the factory premises of Sajjan Chemicals, three to four tanks filled with effluents remain untreated.

Significant industrial waste is haphazardly dumped into the Meycauayan River, a source of domestic and agricultural water for 250,000 people living in and around Manila. Substantial contamination comes from small scale lead recycling facilities along the river at Marilao, and from the many tanneries that dump untreated hexavalent chromium into the river. This river also feeds directly into the Manila Bay, and its effluents contaminate shellfish in commercial fishing areas.
