Heavily impacted river sediment was dredged from areas along the Ohio River and barged to a processing facility located in close proximity to several residences. The processing facility contractor employed the use of a wireless organics vapor monitoring network to measure the effectiveness of active on-site odor control misting and foam dust suppression systems. Vapor concentrations were monitored and recorded. Alarms were transmitted in real time to on-site personnel.
PROJECT OVERVIEW: Deploy proactive monitoring solutions for a construction project being performed in the St. Paul area. A 36- hour continuous concrete pour in close proximity to a community hospital was planned. The hospital had concerns about the effect gaseous emissions from the use of diesel equipment would have on air quality
Twenty-two optical Dissolved Oxygen (DO) sensors were installed in individual wells during a treatability pilot study. The chosen remedy involved the injection of compressed air at two permeable depths within the formation. The customer needed to monitor the delivery of oxygen in order to determine the remedy’s overall effectiveness. The sensors provided real-time DO data to the project team via the Internet to guide decisions, such as increasing air injection pressures or changing injection intervals.
Several sensitive receptors in close proximity to a soil removal project had a potential risk of exposure to both dust and organic vapors.
In 2017 and 2018, California experienced a number of disastrous wildfires. When the fires stopped burning residents returned to their homes to find piles of toxic ash and rubble where they once lived. Thousands of structures were destroyed. Cleanup of the debris was handled as a remedial action. The removal of such debris can be dangerous to sensitive or at-risk populations, particularly for children and senior citizens. Field Data Solutions worked with the contractor to deploy community based monitoring stations that allowed residents real-time access to local data.
