Inspection also found out that nearly 1,000 industries in Pune lacked effluent treatment facilities
An inspection by the Maharashtra Pollution Control Board (MPCB) recently found out that effluent released by industries, specially pharma and chemical, in Maharashtra Industrial Development Corporation (MIDC) area did not follow purification standards. It also found out that nearly 1,000 industries in Pune lacked effluent treatment facilities.
MPCB officials said an inspection in MIDC industrial areas of Ranjangaon, Kurkumbh and Chincholi revealed that treated effluent from common effluent treatment plants (CETP) at these estates was not adhering to pollution control standards.
Parameters such as Ph, biological oxygen demand (BOD), chemical oxygen demand ( COD), suspended solid and total dissolve solid (TDS) level were found to be on a higher side in the effluent treated at the common facilities. The Ph level was found to be 8.3 against the approved standard of 5.5 to 9, BOD was in the range of 190 to 510 miligram per litre against the approved level of up to 100 miligram per litre, COD was in the range of 380 to 1,100 miligram per litre against the permissible limit of 250 miligram per litre. Suspended solid level had to be less than 100 miligram per litre but it was found to be between 96 and 162 miligram per litre.
Effluents released by chemical and pharmaceutical units had higher quantity of BOD, COD and suspended solids, MPCB, officials said, adding that this problem occurred as operation and maintenance of CETPs was not done properly by local industrial associations.
MPCB officials said another area of concern was small scale industries operating in industrial areas of Pimpri and Bhosari. Nearly 1,000 small scale units don't have effluent treatment facilities due to which effluent generated from such units gets released into water bodies, they said. However, MPCB Regional Officer A D Mohekar said there was no grave threat from major engineering companies that operate in Pimpri and Pune as "they don't generate effluents that affect people's health". He said notices have been issued to industries found violating norms. "We have issued 10 notices to industries found violating norms in MIDC areas," he said.
