Impact of Corrosion on Agriculture - Oil spill in 100 acres farmland

[Valliappan Manickam]

A pipeline carrying crude oil for refining developed cracks and spilt oil in about 100 acres of farmland in a village in Nagapattinam district, officials said.

They said people of Manjavadi village detected the leak after they found their farmlands flooded with oil. The oil was being transported through pipeline from the Oil and Natural Gas Commission owned oil well at Adiyakkamangalam to Narimanam for refining, they said. Officials said it was not clear whether the pipe had broken due to recent heavy rains or the soil becoming loose.

ONGC officials said the pipes might have got corroded due to the saline condition in the area.

In August 2011, a similar rupture along the pipeline near river Devanadhi ruined Samba paddy fields. However, the damage was contained by the river, which washed away the oil slicks into the sea.

But now, the crude oil spill has begun flowing along the Kohur irrigation channel, which irrigates over 300 acres, across the villages of Manjavaadi, Anaimangalam, Kohur, Thenkarai and Vadakarai.

It is telling on the already weak prospects of the samba crop. Several acres of paddy fields irrigated by the oil slick-laden water from the channel have been ruined.
