Data released by the Maharashtra Pollution Control Board (MPCB) on noise levels across 25 locations in Mumbai for the seventh day of Ganesh immersions, found Byuclla, Dadar (East) and Girgaum Chowpatty to be the noisiest at 97.4 decibels (dB), 94.8 dB and 91.6 dB respectively.
MPCB calculated noise levels on the first, second, fifth and seventh day from 25 locations along with five locations from Navi Mumbai and nine locations from Thane.
On the fifth day, Girgaum Chowpatty was the loudest at 90.3 Db, followed by Bhandup and Andheri (near Azad Nagar) at 87.8 dB and 87.6 dB respectively.
“Officials from the department carried noise measuring devices and the data has been put together as per Central Pollution Control Board (CPCB) norms,” said Dilip Khedkar, regional officer, Mumbai, MPCB. “We found high noise levels from immersion processions that had loudspeakers, DJ sets, drums, dhols and other instruments. The maximum noise levels were recorded on the seventh day.”
Khedkar said the Mumbai police need to monitor these sites on the last day of immersions and take action against those violating noise pollution rules.
Noise standards as laid down under the Noise Pollution (Regulation and Control) Rules, 2000, requires residential and silence zones to have noise levels not more than 55dB and 50dB during the day (6.30am to 8.30pm) and 45dB and 40dB during the night (8.30pm to 6.30am) respectively.
The first and second day observed less noise pollution as compared to later days. On September 17, a noise level of 87.4 dB was recorded at Grant Road, which was the highest, while 82.4 dB was recorded at Mumbai Central, the highest for the second day (September 18).
Sumaira Abdulali, convener, Awaaz Foundation said, “It is good the MPCB has come out with data on noise levels while the festival is going on so that appropriate action could be taken on the last day of immersions.”
According to the data, in Navi Mumbai, the Airoli traffic police chowki recorded the highest decibel levels on the first day at 89.1 dB, which is the highest for all four days.
Similarly, 83.9 dB was recorded from Court Naka at Thane on the first day, followed by 83.6 dB recorded from Gaondevi Mandir, Naupada on the seventh day.
“Police officers had issues with the readings that Awaaz foundation took because it is a private body, but these readings are the official ones from the government and need to be taken seriously,” said Ajay Marathe, member, Awaaz Foundation.
