Two of five key stations in Gurgaon defunct for two months, air quality checks hit
Gurgaon: Two of the five continuous ambient air quality monitoring systems (CAAQMS) in the district — Vikas Sadan and Manesar — ceased recording data for the past two months. The disruption in real-time air quality monitoring raised alarms among experts. According to the Central Pollution Control Board (CPCB) guidelines, areas with populations between 10,00,000 and 50,00,000 should have a minimum of five CAAQMS and three manual monitors to ensure comprehensive air quality assessment. Gurgaon, with a population of 15.1 lakh as per the 2011 Census, barely meets this requirement. The malfunctioning of two monitors further exacerbates the city's already inadequate air quality monitoring infrastructure. "The current number of monitors is insufficient for a city of this size and population density. The city needs at least eight monitoring stations to track and manage air quality effectively," said Shubhansh Tiwari, research associate at the Centre for Science and Environment. Experts said the five monitoring stations are not properly distributed across the district, which leads to inaccurate air quality data. "Gwalpahari, Sector-51, and Teri Gram monitoring stations track data from one side of the city while Vikas Sadan is the only one to get data from the old city. Thus, the stations are not ideally located. More stations should be set up where most people live to check the pollutants they are exposed to," he added. The monitoring station at Gwalpahari is run by the India Meteorological Department, while the stations at Vikas Sadan, Teri Gram, Sector 51, and Manesar are under HSPCB. These stations, however, do not give an ideal picture when calculating the data as they do not cover all district zones. "Gurgaon, the third most polluted city in India in 2024, following Byrnihat in Meghalaya and Delhi, lacks sufficient air quality data. With a pressing need for more monitoring stations to track pollution levels, evaluate mitigation strategies, and inform policy decisions, it's concerning that two existing stations are currently non-functional," said Manoj Kumar, air analyst at the Centre for Research on Energy and Clean Air (CREA). "As a non-attainment city, Gurgaon should be included in the upcoming revision of the National Clean Air Programme for focused action," he added. A non-attainment city consistently fails to meet the national ambient air quality standards defined by the Central Pollution Control Board (CPCB). The malfunctioning monitors are located in critical areas, leaving significant gaps in data collection. This lack of real-time data hampers the ability to implement timely and effective measures to combat air pollution. Residents have expressed frustration over the situation, citing health concerns due to prolonged exposure to poor air quality. Acknowledging the issue, HSPCB said efforts are underway to fix the issue. However, the delay in restoring full monitoring capabilities has left many questioning the efficiency of the current system. "The firm that was given the tender for the monitoring stations is demanding an increase in price to maintain and upload the data. We are currently trying to work out a solution," said Vijay Chaudhary, regional officer, Gurgaon (south). The air quality in Delhi-NCR plummets to dangerous levels as the region is blanketed by toxic haze due to a combination of dry weather and local emissions like garbage burning, road dust, and gusty winds. Without a proper understanding of the air quality, residents and monitoring agencies can't take adequate steps to mitigate pollution.
