Gurugram air quality monitoring stations reopened, restoring pollution data; many Haryana districts’ monitors remain offline amid maintenance delays.

Gurugram air quality monitoring facilities have reopened, giving locals access to real-time pollution data. Many stations in Gurugram and other districts have reopened after being shut down because of outdated maintenance contracts. According to experts, routine inspections are essential.

The four monitoring stations in the city have resumed operations after being inactive for several months, giving residents of Gurugram access to real-time air quality data once more. The sensors have been re-calibrated, according to officials, and are now connected to dashboards of the state and federal governments, giving a clear view of the air quality in the city.

This comes after 29 of Haryana’s 31 air quality monitoring stations were out of commission from December 2024 to April 2025 as a result of maintenance contracts expiring. Because of this nationwide stoppage, there was a “data blackout,” which prevented the public and authorities from accessing reliable pollution statistics for almost five months.

Present Situation in Haryana

Throughout the state, the restoration of services is being done in stages:

Operational Districts: In addition to Gurugram air quality stations have returned to service in the following districts: Faridabad, Karnal, Ambala, Bahadurgarh, Palwal, Panipat, Bhiwani, Sonipat, Jind, Nuh, and Sirsa.

Stations Still Closed: There are still no working monitors in a number of important districts, including Panchkula, Ballabhgarh, Charkhi Dadri, Dharuhera, Fatehabad, Hisar, Kaithal, and Yamunanagar.

Update for Gurugram: Although the stations are online, there is currently insufficient data for the TERIGRAM and Vikas Sadan monitors in Gurugram to show the Air Quality Index (AQI).

Repairs and Professional Advice :

Two businesses, ENVEA India and Aacom, have been tasked with maintaining and repairing the stations, which track pollutants like PM 2.5, PM 10, and nitrogen oxides.

Due to the extended shutdown, some reopened stations are experiencing technical problems, such as non-functional diesel generator sets, according to Nirmal Kashyap, head of the Haryana State Pollution Control Board’s air cell. These are being fixed right now.

The monitoring system has been restarted ahead of the winter season, when pollution usually peaks, which has been welcomed by environmental specialists. They warn, nevertheless, that merely turning on the stations is insufficient. To guarantee efficacy and accountability, they have demanded ongoing public data sharing, third-party audits, and routine inspections. Experts also emphasized how urgent it is to learn from previous administrative mistakes and reactivate the remaining stations.
