Punjab has been reported amongst the worst performing states in the country when it comes to checking water pollution. With at least seven grossly polluting industrial units dumping their toxic waste directly in rivers and lakes, the state has been noted amongst the worst defaulters in the country. Of the 20 grossly polluting industries not even half, nine units, comply with norms regarding water pollution. The others are discharging toxic waste straight in the rivers and lakes. Punjab ranks seventh on the list of defaulting states with most other states --Bihar, Tamil Nadu, Andhra Pradesh, Assam and Jharkhand -- managing to have not a single such polluting unit.
