FAISALABAD: 

A study recently conducted by the Institute of Soil Chemistry and Environmental Sciences at the Ayub Agricultural Research Institute (AARI) in Faisalabad says close to 65 per cent of agricultural land in six important cities of the province has become uncultivable because of farmers using water contaminated with industrial waste and sewage to irrigate the land.

More than half of erstwhile fertile land in Faisalabad, Kasur, Multan, Lahore, Rawalpindi and Gujranwala has become barren or is close to becoming infertile because of the use of contaminated water for irrigation, the report says.

Spokesperson for the AARI told journalists on Monday that they had taken 338 samples of soil from Faisalabad and its surrounding localities and sent them to a laboratory for chemical analysis. The test report revealed that 64 per cent of the samples contained a high quantity of lead and 100 per cent of the samples had zinc over and above the standard set by the World Health Organisation and the Pakistan Environmental Quality Standard.

He said 178 samples were collected from Kasur where 50 per cent of the samples had lead and zinc. He said 154 samples were taken from Gujranwala and lead was found in 60 per cent of the samples and zinc in 48 per cent of samples.

Similarly, 444 samples were collected from Multan and lead was found in 51 per cent of the samples and zinc in 49 per cent of the soil samples. He said 372 samples were taken from Rawalpindi and lead was detected in 73 per cent of the samples and zinc in 61 per cent samples collected.

The spokesperson said 446 samples were taken from agricultural areas in and near Lahore and the test report showed presence of lead in 70 per cent of the samples and zinc in 62 per cent of the samples collected.

“It is the high quantities of lead and zinc in our soil that is rendering it uncultivable…it also leads to pollution in the agricultural production.”

Responding to a question, the AARI spokesperson said that most of the farmers in these cities were using industrial waste and domestic sewerage to irrigate their lands. “Industrial waste is full of harmful chemicals and domestic sewerage contains poisonous items which are then absorbed by the vegetables and grains grown on the land. After a while, the land irrigated with such water becomes completely barren.”

He said the report suggests that the government should take immediate notice of the situation and construct separate drains for industrial waste and domestic sewerage. He also called for laws against the use of such water for irrigation.

    This is known to all concerned that municipal, industrial effluent & agriculture run off go to water bodies and river systems. Reason, no city has sewage treatment facility. Similarly industry avoidance to treat their effluent. This is due to lack of political will and weakness by environment protection agencies. This needs concerted efforts at all levels which is not forthcoming.Recommend
