Welcome to the LA County Public Works Devil’s Gate Reservoir Restoration Project air quality monitoring website. As part of the restoration project, LA County Public Works is operating an air quality monitoring network that collects continuous data on ambient air quality and meteorological conditions in the Devil’s Gate Reservoir project site.
A total of six monitoring stations are strategically located within and surrounding the restoration project site for compliance purposes and to monitor potential air quality impacts resulting from the restoration project. The table below provides a summary of the monitoring stations and types of air pollutants being monitored. As noted in the table, there are two types of monitoring stations:
NOTE: Air monitoring Stations #3 and #5 were relocated on September 26, 2020 in preparation for the sediment removal activities at the Mining Pit and Johnson Field planned for October 2020. Future locations for these monitoring stations will be reassessed once the excavation of these areas are completed.
The air quality monitoring data collected from the monitoring stations will be used to better manage and provide feedback to LA County Public Works to implement best management practices and emission mitigation measures to reduce potential negative environmental and public health impacts by the restoration project.
The real-time monitoring data collected from the monitoring stations are available for public viewing. The data can be viewed through the following links:
