Candor: EPA CASTNet Site is an air monitoring station located at 136 Perry Drive in Candor, Montgomery County, North Carolina, United States. The facility is part of the EPA's Clean Air Status and Trends Network (CASTNet), which monitors the effects of air pollution on ecosystems and human health. As a rural site, it contributes to understanding regional air quality trends. The station operates under the regulatory framework of the US EPA's Air Quality System (AQS) and follows standard protocols for measuring criteria pollutants and atmospheric deposition. CASTNet sites typically measure ozone, sulfur dioxide, nitrogen oxides, and particulate matter, along with meteorological parameters. The most recent sample date is June 29, 2024, indicating ongoing data collection. This monitoring station plays a key role in assessing the effectiveness of air pollution control programs in the southeastern United States. Its rural location helps differentiate between local and transported pollution sources, supporting research on acid rain, haze, and ecosystem impacts. The data supports environmental policy decisions and public health advisories.
Environmental context
The Candor site is situated in a rural area of North Carolina, where air quality can be influenced by both local sources (agriculture, traffic) and regional transport from urban and industrial centers. CASTNet monitoring focuses on long-term trends in atmospheric deposition and ozone, which are critical for assessing ecosystem health. The site's representativeness of regional conditions is enhanced by its rural siting, avoiding direct local emission influences.
