Imperial County Residents Help Tackle Air Monitoring

Residents from Imperial County, California are benefitting from a new air quality monitoring network of low-cost environmental sensors that provide real-time pollution data. The county is subject to many air pollution sources such as field burning, unpaved roads, several industrial facilities and its close proximity to the Salton Sea. The City of El Centro, California, which is located in the county, has the fifth-worst air quality in the United States, according to a study by the American Lung Association. While there are several different types of air pollution, particulate matter (PM) is a main concern in Imperial County. PM is a mixture of extremely small particles and liquid droplets that get into the air.

The Arizona Department of Environmental Quality's Water Quality Division

With an average rainfall of only 12.5 inches per year and a population that's growing faster than the country's , Arizona is a state that faces unique challenges, especially when it comes to clean, safe water. The Water Quality Division of the Arizona Department of Environmental Quality (ADEQ) protects and enhances public health and the environment by monitoring and regulating drinking water. And although they make use of the latest scientific methods and new technology, given the current state of Arizona's water system, they also rely upon low-tech equipment and cooperation from members of the community to monitor water quality in the state. Team members in the Groundwater Protection Program work to sample, test and characterize groundwater quality in all 51 of Arizona’s basins.
