Route 15 Orrington Mercury Vapor Sampling Site - Air Monitoring Station in Maine

The Route 15 Orrington Mercury Vapor Sampling Site is an air monitoring station located in Orrington, Penobscot County, Maine, United States. This facility is part of the national air monitoring network and is operated by Holtrachem Manufacturing Company. It focuses on mercury vapor sampling, contributing to the understanding of atmospheric mercury levels in the region. The station operates under the regulatory framework of the US EPA Air Quality System (AQS), which sets standards for ambient air quality monitoring. While specific technical parameters are not detailed, mercury vapor monitoring typically involves specialized instrumentation to detect trace levels of elemental mercury. Such monitoring is crucial for assessing local and regional mercury deposition, which can impact ecosystems and human health. This site provides valuable data for environmental monitoring in Maine, a state with significant forested and aquatic ecosystems sensitive to mercury pollution. The data supports research on atmospheric transport and deposition of mercury, aiding in the development of regulatory policies and public health advisories. The station's location along Route 15 ensures representative sampling of ambient air in a rural setting.

Mercury vapor monitoring is critical in regions like Maine, where atmospheric mercury from industrial and global sources can deposit into lakes and forests, bioaccumulating in fish and wildlife. The Route 15 site helps track local mercury levels, supporting the EPA's Clean Air Mercury Rule and the broader goal of reducing mercury emissions. The station's rural siting provides baseline data away from urban point sources, aiding in understanding regional transport patterns.
