Many remediation and construction projects around the country require continuous air monitoring for particulates (aka “dust”). Data collection and evaluation can be during active operations (i.e. working hours) as well as round-the-clock (i.e. 24/7).
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.
FDS supplied equipment and communication gear at a storm water outfall to support compliance monitoring at a Superfund Site in northern Florida. The purpose of the equipment was to the monitor flow conditions and remotely collect a composite storm water sample when specific data conditions were met.
Twenty-two optical Dissolved Oxygen (DO) sensors were installed in individual wells during a treatability pilot study. 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.
January 10, 2019 - Field Data Solutions (FDS), along with it’s sister company Field Environmental Instruments, just finished a nine-month contract at Naval Station (NS) Newport in Rhode Island. From March to December of 2018, FDS deployed equipment to monitor turbidity in harsh saltwater conditions.
FDS’ expertise was enlisted by a contractor rehabilitating rotting pilings supporting a concrete aircraft carrier pier. Divers had to pump concrete underwater into a mold to repair the pier while following compliance guidelines to protect Narragansett Bay.
A turbidity curtain was used to contain debris inside the work zone. Just outside the curtain, FDS deployed three YSI EXO2 water quality monitoring sondes, attached to a coastal buoy, to monitor possible increases in turbidity as a result of the underwater activities affecting sediments and particulates. This integrated system included real—time monitoring equipment at various depths outside the curtain with real-time adjustments for background concentrations. Data was transmitted via cellular communication to the cloud, where algorithms verified the data adjusted for background, compared the data to action levels, and compiled the information in daily reports for the FDS team at the company’s headquarters in Pittsburgh.
If turbidity levels exceeded those allowed by EPA regulations, the team received text alerts from the FDS monitoring system and alerted the contractor to suspend work until the turbidity returned to below the accepted threshold.
“Although ambient water quality readings were valuable over the nine-month deployment, no exceedances of established thresholds were detected as a result of the pier rehabilitation,” says John Wright of the FDS team.
The work came after three years of FDS working on at least six similar projects at NS Newport.
“We have a lot of expertise in this line of work,” Wright says.
FDS supplied instrumentation and communications hardware for remote real time monitoring of an existing groundwater monitoring and active product recovery system. The project involved installing a Magnehelic pressure transmitter and gauge on the effluent of an existing on-site SVE (Soil Vapor Extraction) unit, coupled with a PID (Photo Ionization Detector) for direct reading of TVOC (Total Volatile Organic Compound) concentrations in the exhaust flow.
At a large-scale soils removal and consolidation project, spanning three construction seasons, organic vapor and dust monitoring instruments were deployed to measure potential air impacts from project implementation.
