Chennai:
Water Resources Department will now conduct a study in and around
Pallavaram to ascertain the presence of heavy metals like chromium and
lead in the ground water.
A Water Resources Department official told Express that the ground
water wing would be conducting the study after a report from Indian
Express quoting a study by Anna University raised serious concerns
about the health of those who depend on ground water, which has been
polluted with heavy metals.
The study, ‘Trace Metals Contamination of Groundwater In and Around
Tannery Industrial Area of Pallavaram in Chennai’, which was conducted
by Centre for Water Resources, Anna University on January 2014,
assessed 18 groundwater samples collected from the tannery accumulated
site in Pallavaram and found that and found that the presence of
chromium and lead in groundwater exceed the normal limits.
It found that not only that the groundwater is affected by leaching in
the area but also the waste from the industries dumped at the Periya
Eri is causing groundwater related problems.
Meanwhile, Water Resources Department has asked the chief engineer of
Chennai Corporation for setting up a labaoratory to analyse the
presence of heavy metals in the water samples.
Interestingly, a report of the Comptroller and Auditor General of
India has highlighted that special parameters like heavy metals,
pesticides, inorganic carbon, organic carbon and total carbon which
cause health hazard could not be analyzed in water samples since 2006
due to failure of the DMK regime to take any initiative in setting up
Geo-Chemical Laboratory and appointment of Government analyst.
The lab was recommended by Central Pollution Control Board in May
2006. The report stated that Water Resources Department did not seek
fresh recognition since it could not comply with CPCB norms in respect
of staff pattern.
Special parameters become all the more significant in view of the fact
that department themselves identified presence of heavy metals such as
lead and iron beyond permissible limit in water as early as 2003,” the
report stated.
Currently, general parameters are only being tested, the report added.
It also stated that water quality data relating to special parameters
which cause health hazards for human beings were not captured for
surface water and ground water in Water Quality Data Entry System
database as these tests were not conducted.
