US-EPA Laboratory Air Monitoring Station, Narragansett, Rhode Island

The US-EPA Laboratory is an air monitoring station located on Tarzwell Road in Narragansett, Washington County, Rhode Island. It operates under the oversight of the Rhode Island Department of Environmental Management and the Department of Health, providing critical data on ambient air quality in the region. As part of the US EPA Air Quality System (AQS) network, this station monitors criteria pollutants and other atmospheric parameters to ensure compliance with National Ambient Air Quality Standards (NAAQS). The station's coastal location in southern Rhode Island allows it to capture both local and regional air quality influences, including maritime air masses and emissions from nearby urban and industrial areas. The data collected supports public health assessments, regulatory compliance, and environmental research. The station's long-term operation and recent sampling activity (last sample date August 2025) indicate consistent reporting continuity, which is essential for tracking air quality trends and informing policy decisions in Rhode Island.

The Narragansett area experiences a mix of coastal and suburban air quality influences. The US-EPA Laboratory station's siting near the Atlantic Ocean provides representative data on background marine air, while also capturing pollutants transported from inland sources. Its inclusion in the EPA AQS network ensures standardized monitoring of criteria pollutants such as ozone, particulate matter, and nitrogen dioxide. The station's parameter coverage and reporting continuity are key to understanding local air quality dynamics and supporting regional air management strategies.
