Overview
Hammond-Purdue/Powers Bldg. Purdue University is an air monitoring station in Hammond, Indiana, part of the CSN Supplemental network. It is operated by Research Triangle Institute and monitors criteria pollutants and speciation.
Hammond-Purdue/Powers Bldg. Purdue University is an air monitoring station located at Purdue University Calumet in Hammond, Indiana, United States. The station is part of the Chemical Speciation Network (CSN) Supplemental program, which focuses on measuring particulate matter speciation to support air quality management and health research. The station operates under the U.S. EPA's Air Quality System (AQS) framework, which sets standards for criteria pollutants and speciation monitoring. As a CSN Supplemental site, it collects data on fine particulate matter (PM2.5) components such as sulfates, nitrates, carbon, and metals. The reporting agency is Research Triangle Institute (RTI) in RTP, NC, which manages the network's quality assurance and data reporting. This monitoring station serves the Hammond metropolitan area and contributes to regional air quality assessments in the Chicago-Gary industrial corridor. Its data supports regulatory compliance under the Clean Air Act and helps inform public health advisories. The station's location near industrial sources and urban areas provides representative sampling for population exposure studies.
Environmental context
The station's location in Hammond, Indiana, places it within the Chicago-Gary industrial corridor, an area with significant emissions from steel mills, refineries, and transportation. The CSN Supplemental network focuses on PM2.5 speciation, which is critical for understanding source contributions and health impacts. The station's siting near Purdue University ensures representativeness for urban and industrial exposure, supporting the EPA's goal of protecting public health and the environment.
Frequently asked questions
The station is located at Purdue University Calumet, Powers Building, 2200 169th St., Hammond, Indiana, USA.
The Chemical Speciation Network (CSN) Supplemental monitors fine particulate matter (PM2.5) speciation, including sulfates, nitrates, carbon, and metals, to support air quality management and health studies.
The station is operated by Research Triangle Institute (RTI) based in Research Triangle Park, North Carolina, under the U.S. EPA's Air Quality System.
Air monitoring in the U.S. is governed by the Clean Air Act and implemented through the EPA's Air Quality System (AQS), which sets standards for criteria pollutants and speciation monitoring.
PM2.5 speciation helps identify sources of particulate pollution, such as industrial emissions or vehicle exhaust, and informs targeted regulations to protect public health.
