GROUNDWATER REMEDIATION AND PRODUCT REMOVAL SYSTEM
ELEMENTARY SCHOOL, NEW YORK
Contract Value:
$349,000
MES was retained to construct a Dual-Phase Vacuum Extraction remedial system at an elementary school to contain and reverse the effects of the spill of nearly 30,000 gallons of No. 2 Fuel Oil which had leaked from a ruptured transfer pipe.
Construction was constrained by intense deadline pressure and physical restrictions which limited equipment access. All construction activities were required to be completed within one summer while students were on break. Construction activities were completed in basements, crawl spaces, narrow hallways, and courtyards with limited access. Many of these environments introduced the complication of Confined Space Entry and required forced ventilation.

Construction included:
- Installation of six (6) two-inch (2”) inch diameter dual-phase wells in a completely enclosed courtyard using a tripod and hammer rig. Equipment access was limited to a 32.5-inch diameter doorway.
- Installation of two (2) two-inch (2”) diameter dual-phase wells into a crawl space from the hallway floor above using a tripod and hammer rig. The hallway ceiling allowed for a maximum of 9.5 feet of clearance after removing ceiling tiles.
- Installation of three (3) two-inch (2”) diameter dual-phase wells in a basement storage area with eight-foot (8’) ceilings using a tripod and hammer rig. Drilling was not allowed through the ceiling above this area. The basement floor was an eight-inch (8”) thick concrete slab which was removed with a jackhammer.
- Installation of three (3) two-inch (2”) inch diameter dual-phase wells outside the building using a drill rig equipped with hollow stem augers.
- Installation piping to manifold all wells through crawl spaces and trenches to a treatment system housed outside the building.
- Installation of a 40-foot long treatment trailer containing vapor and water treatment equipment. Equipment used in this system included liquid ring pumps, liquid and vapor phase carbon vessels, bentonite/anthracite adsorbers, oil/water separation, a fully automated control system with remote monitoring, and access to the motor control center.
- Startup, testing, and O&M of the remedial system.
- Injection of ORC grout using direct push probes outside the school building.
