Landfill Debris Removal - NRTF Dixon
Removed and disposed of auto bodies/parts, caissons, metal and debris
Backfilled excavations and restored natural topography
Avoided unnecessary sampling and analysis
Cut schedule in half

"I would highly recommend the CKY team for other projects." -- ROICC NWSSBD Concord

Landfill Cap - Robins AFB
RCRA landfill cover and leachate collection system
Effective use of geosynthetics and groundwater modeling techniques saved construction costs
2000 feet of horizontal wells
200 GW monitoring wells
CKY roles: design, construction oversight, O&M, LTM

"I would unreservedly recommend CKY for work of similar scope."

Painesville, OH FUSRAP Site Radwaste Cleanup
Removed 1300cy Radium 226-contaminated soil from 1/3-acre parcel
Successfully handled schedule constraints and 64% increase in volume
Implemented cost-saving value engineering procedures 
Non-interfering with the operating Uniroyal Chemical Company site

"CKY performed this project in a satisfactory manner. I thoroughly enjoyed working with the project manager."

O&M of Bioventing Diesel Fuel Cleanup at MCB Camp Pendleton
Troubleshooting and maintaining 2 bioventing systems at former UST sites
Successfully transitioned work from the remedial action contractor
Expect to attain closure of one of the sites in six months

 

Multiphase Extraction and Treatment - NAS Lemoore
Constructed discharge pipe and four-acre infiltration gallery
Constructed 45 extraction wells and piezometers
Constructed all pads, piping and electrical service
Installed 4 extraction units and 1 catalytic oxidizer unit
Installed GAC water treatment system
Provided system operation, monitoring and maintenance

 

Detroit Arsenal PCB Remediation
Excavated and removed 1000cy PCB-contaminated soil
Removed free PCB product
Connected waste oil trench drain piping to an OWS
Obtained MDEQ site closure

"CKY addressed an additional 300 cubic yards of previously unidentified PCB contaminated soil at the Building 201N site in an expeditious manner. We have been very pleased with CKY's execution of the Louisville District PRAC contract in the completion of this and a number of other tasks at the Arsenal."

NCTS San Diego Det. Stockton Debris Removal
Removed/recycled 13,000 cy concrete, asphalt and metal
Restored land contours to original state
Protected endangered species

"It has been my pleasure to be the project engineer working at NCTS Stockton. This excellent CKY team kept the job moving by defining the problem and providing sound engineering solutions."

 

LA AFB Soil Vapor Extraction for Gasoline-Contaminated Soil
Hired as installation contractor
Critiqued RI/FS contractor’s engineering design
Modified and installed the SVE/thermal oxidizer system

"CKY demonstrated good engineering insight and finished this project on time and on budget."

 

LA County MTA - Former Lumber Yard Bioremediation
Designed and installed a 160ft x 60ft Land Treatment Unit (LTU)
System included manifolding for aeration and nutrient delivery
Remediated soil contaminated by lubricating and crankcase oils 
Closed site 3 months ahead of schedule with 50% savings

"CKY’s work demonstrated that land treatment was by far the best alternative for this site."

 

Chemical Stabilization - Norton AFB Small Arms Firing Range
High concentrations of lead (1,550 to 26,000 ppm) and dioxins
Excavated, treated and disposed 3,496 tons of contaminated soil
Stabilized contaminants on site with Portland cement and water
Clean overburden soil screened for lead with an X-ray fluorescence (XRF) analyzer
 and for PAHs with an immunoassay kit prior to use as backfill
Agency site closure granted

Landfill Maintenance - Naval Base Ventura County
