Goa State Pollution Control Board has been conducting ambient air monitoring at 18 fixed locations under NAMP. Of these 10 locations are in South Goa District and monitoring values shows that Vasco is moderately polluted and Ponda is also showing marginal higher values in month of April . Out of all of Goa's major towns, Vasco appears to be the most polluted. Ponda, Panaji, Mapusa, and Margao follow in quick succession. One of the reasons being Vasco appearing as most polluted area is two coal-handling units located at Vasco, breaching the air quality norms. GSPCB has imposed penalties on them for causing air pollution. Stone-crushing unit, multi-dwelling unit residential complex, two hotels / commercial establishment and one trawler repairing yard are also penalized by GSPCB for violating the air quality norms. Although the State of Goa does not have city categorised under the “Non-Attainment Cities – NAC and Critically Polluted Industrial Estate (CPIE) / Cluster. However, it is proposed to monitor the Ambient Air-Quality (AAQM) at regular intervals. Goa State Pollution Control Board (GSPCB) will continue to carry-out AAQM. In addition, site-specific air-quality monitoring is being conducted by the Board with the help of mobile Online Continuous Ambient Air Quality Monitoring System (CAAQMS). The State is in the process of purchasing 07 Noise Monitoring devices/measurement meters to be delivered to each Taluka Sub-Divisional Magistrate to monitor the enforcement of Noise Pollution (Regulation and Control) Rules, 2000.
