High Vacuum Dual Phase Extraction & Groundwater Treatment Systems Saving the Environment One Drop At A Time

Your Remediation One Stop Shop Cal. Clean has a working relationship with numerous consultants and contractors throughout the US to assist with the assessment, cleanup, and case closure of your site(s). We help manage the remediation project from beginning to end. No lengthy reports to review and submit to the Agency. All data provided to consultant weekly. Cal. Clean is interested in Performance Based Contract (PBC) projects anywhere in the US. With truck mounted extraction systems and water treatment systems located in numerous areas throughout the US, we can mobilize anywhere. We handle your money like it is our own. There are no hidden mark-ups. We get your location to closure much faster without the big capital investment.

Performance Based Contract Projects Reduces Overall Project Costs Quicker Cleanups Better For the Environment q Guaranteed q Cutting Edge Technology Used States Moving Toward PBC/PFP q Lowers v. The q Funds Results Administrative Costs State of Florida has seen a 64% savings Easier to Control Risk Transferred to Contractor Versus Agency

System Advantages Most Cost Effective (Lowest $ / lb. Hydrocarbon Removed) No Capital Or Maintenance Cost Outlays Can Mobilize Quickly and Make Adjustments On The Fly No Shutdown Of Operations Do To Installation Of Trenching Low Noise For 24 -Hour Operations In Neighborhoods Occupies Less Space at Station High Capacity Equipment (SCFM and GPM) Various Permitting Already Obtained 100% Guaranteed Up Time Quality Technical Expertise And Supervision Mobile Fleet Of Truck And Trailer Mounted Extraction Systems Faster Clean-up = Quicker Release Of Long Term Liability Can extract from depths of >270 feet

Enhanced Remediation Techniques Use Air Sparging to enhance HVDPE Use HVDPE to remove diesel free product Introduce Surfactants to assist with diesel cleanups Clean up contaminated vadose only sites quickly with high vacuum systems New well box and underground piping design for HVDPE operations Use periodic extractions (w/interruptible pricing) to address interim rebound

Systems Comparison Cal. Clean HVDPE Truck-Mounted Mobile Systems Standard S. V. E. Pump & Treat Fixed Based Systems (Few Mobile Systems) High Capacity 450 CFM Systems Typical System is 250 CFM But Typical System is 2 -20 GPM But Can Extract 5 -50 GPM Water Cannot Extract Vapors Can Extract & Destroy up to Typical System can Destroy up to Cannot Destroy Hydrocarbon 130 pounds of Hydrocarbons 40 pounds per hour of Vapors per hour hydrocarbons Can Extract up to 29” Hg (394” Typically Extracts up to 10” Hg H 2 O) i. e. . Large Radius of (136” H 2 O) i. e. . Smaller Radius of Not Applicable For Vapors Influence, Less Extraction Wells Influence, More Wells Required, Required for Site Greater Costs Extract Vapor & Groundwater Extract Vapor Only Extract Groundwater Only Can Lower Groundwater Table to Address Vadose, Capillary Fringe & Saturated Zones Cannot Extract Groundwater Can Only Remove Groundwater, No Vapor

Comparisons (misc. ) Cal. Clean HVDPE Standard S. V. E. Pump & Treat Can Mobilize to a Site Within Hours of a Call. Can Attack Source Immediately Typically Takes 9 -15 Months To Install System - Allows Plume Size To Increase Typically Takes 6 -15 Months to Install System - Allows Plume Size to Increase Can Startup At A Site Quickly Takes Many Months Before Startup Cannot Pull Offsite since fixed Can pull offsite when concentrations Drop Off To Allow For Rebound Can Adjust Number of Days of Cannot Adjust Days of operation Operation To Maximize Recovery Constant Onsite Monitoring of No Onsite Monitoring of Influent Vapor Concentrations Cannot Adjust Days of operation Occupies Space At Station Occupies Full-Time Space On "Only" During Onsite Operation Small Station Property Occupies Full-Time Space On Small Station Property Low Noise Operation (Great For High Noise Systems (Complaints Residential Areas) From Neighbors) Low Noise Not Applicable

Comparisons ($$) Cal. Clean HVDPE Standard S. V. E. System Manned At All Times To System Unmanned, Cannot Adjust Stinger Depths to Depths in Extraction Wells Maximize Recovery No Capital Cost Outlay High Capital Cost Pump & Treat System Unmanned, Cannot Adjust Depths In Extraction Wells High Capital Cost Closures Can Be attained Earlier Closures Typically Take 3 to 10 Years Closures Typically Take 5 to 30 Years (possibly in less than 1 year) No Trenching Needed Trenching Required No Shutdown Of Station Shutdown Station for 2 - 4 Weeks Loss of earnings No Long Time Commitment Needed For Use At A Site Long Term Commitment is Needed No Cost Of Decommissioning High Cost Of Decommissioning And Loss Of Value Of System No Weekly O&M Cost(s) Highly Weekly O&M Cost(s) High Weekly O&M Cost(s) Faster Closures = Quicker Release of Liability Slower Closures = Long Time Liability Slower Closures = Long Term Liability
