Grayson Lake Air Monitoring Station, Carter County, Kentucky | NATTS Network

Grayson Lake is an air monitoring station located at Camp Robert Webb in Carter County, Kentucky, United States. It is part of the National Air Toxics Trends Stations (NATTS) network, which focuses on long-term monitoring of hazardous air pollutants. The station is operational and contributes to the US EPA's Air Quality System (AQS). The station operates under the regulatory framework of the US Clean Air Act, with data reported by Eastern Research Group. As a NATTS site, it typically measures a suite of toxic air pollutants, including volatile organic compounds and metals, to assess trends in air quality. The station's rural location provides background concentration data representative of regional air quality. Environmental monitoring at Grayson Lake supports the understanding of air toxics exposure in rural Kentucky. The data collected helps inform regulatory decisions and public health assessments. The station's long-term operation ensures continuity in tracking pollutant trends, which is critical for evaluating the effectiveness of air quality management strategies.

Grayson Lake's rural setting in eastern Kentucky provides baseline air quality data away from major urban and industrial sources. The NATTS network emphasizes monitoring of hazardous air pollutants, which complements criteria pollutant monitoring by other networks. The station's siting is representative of regional background conditions, and its continuous operation supports trend analysis for policy evaluation.
