O&M at Joint Base Cape Cod, MA – USACE New England District
KGS/Trinity performs Environmental Services at Joint Base Cape Cod (JBCC) located in Bourne, Massachusetts for USACE New England District. JBCC encompasses 22,000 acres, 15,000 acres comprise the northern training area, the major training area for Army National Guard soldiers in the Northeast, where soldiers practice maneuvering exercises and bivouacking, or camping, and use the small arms ranges.
The project includes the Operation and Maintenance (O&M) and repair of 13 groundwater extraction and treatment systems consisting of 17 treatment systems and mobile treatment units that employ a treatment train of ion exchange resin (IX) and granular activated carbon (GAC) to treat a combined volume of 2,800 gallons per minute of groundwater contaminated with explosives and perchlorate prior to re-injection via injection wells and infiltration galleries. KGS/Trinity maintains an inventory of spare parts and supplies to ensure that routine repairs are conducted in a timely manner to minimize systems downtime. Treatment system performance sampling is conducted at the influent, midpoint, and effluent of each system and O&M reports documenting system performance and optimization are submitted monthly. Other O&M activities completed include:
- IX and GAC media exchanges
- Extraction and injection well maintenance and pump repair/replacement
- Infiltration gallery maintenance
- Electrical and SCADA maintenance
- DigSafe reception and mark-out of up to 1,500 notices annually
