Overview
Lewes SPM SITE, NEAR UD ACID RAIN/MERCURY COLLECTORS is an operational air monitoring station in Lewes, Delaware, operated by the Delaware Department of Natural Resources and Environmental Control. It monitors acid rain and mercury deposition as part
The Lewes SPM SITE, NEAR UD ACID RAIN/MERCURY COLLECTORS is an air monitoring station located at the University of Delaware College of Marine Studies in Lewes, Sussex County, Delaware. This station is part of the United States Environmental Protection Agency's Air Quality System (AQS) network, which provides ambient air quality data for regulatory and research purposes. The facility is operated by the Delaware Department of Natural Resources and Environmental Control (DNREC) and has been active with recent sampling as of June 2025. The station specializes in monitoring acid rain and mercury deposition, which are critical parameters for understanding atmospheric deposition and its impact on ecosystems. While specific technical specifications are not detailed, the station likely employs wet deposition collectors and mercury analyzers consistent with the National Atmospheric Deposition Program (NADP) and the Mercury Deposition Network (MDN). These measurements support compliance with the Clean Air Act and inform regional air quality management. Located near the Delaware coast, this station provides valuable data on the transport and deposition of pollutants from both local and distant sources. Its proximity to marine environments makes it particularly relevant for studying the interaction between atmospheric deposition and coastal ecosystems. The data collected here contributes to national assessments of acid rain and mercury pollution, supporting environmental policy and research on ecosystem health.
Environmental context
The Lewes SPM site is situated in a coastal region of Delaware, where atmospheric deposition of acid rain and mercury can affect sensitive ecosystems such as the Delaware Bay and nearby wetlands. Monitoring these parameters is essential for assessing the impact of emissions from power plants, industrial sources, and urban areas. The station's data helps track long-term trends in deposition chemistry and supports regulatory programs under the Clean Air Act, including the Acid Rain Program and Mercury and Air Toxics Standards (MATS).
