Seneca Companies
Seattle, Washington – 10/07
Our design: Dual Phase System using a high-vacuum rotary claw blower, treat the water with an oil/water separator and air stripper, and treat the off-gas with vapor phase carbon.

Kansas City, Kansas – 10/07
Our design: The 12-foot by 36-foot metal-sided building houses an SVE and Air Sparge system. The 150 horsepower SVE blower is designed to do 2,500 scfm @ 10” HG vacuum, while the 75 horsepower rotary screw air compressor does 375 cfm. We are also treating the off-gas with a thermal oxidizer.

Earthworks Environmental
The following projects were performed by EarthWorks Environmental, Inc. in developing the Matrix Enhanced Treatment System, “METS”, for widespread commercial use. These projects were completed in real world conditions and were required to meet remediation standards established by regulatory authorities. The soil was treated with no special preparation or enhancement other than screening of excess debris as noted.

The projects were completed using either the METS concept, “Project A”, or METS equipment in a variety of industrial and commercial applications and soil types. The small “Eureka 40″ pre-production unit is designed to process 40 tons of soil per hour while our larger “Yuba 160″ production rig can treat over 160 tons of soil per hour on site and on time.

In all cases, the treatment method involved either a bio or chemical reagent process to completely degrade the contaminant. It was our further goal to encounter increasingly more difficult soils and contaminants. We are continuing in that effort during Project Year 2004 with more difficult soils and increased soil volumes.

Field Project A
Location: Nevada
Treatment: Surfactant w/catalyst oxidizer
Volume of soil: 1000 yd3
Contamination type(s): JP-8
Average level of contamination: 15- 18,000 PPM
Peak levels of contamination: 18,000 PPM
Elapsed time for project: 5 Days
Elapsed time after completion prior to collecting confirmation samples: 21 Days
Number of confirmation samples collected: 20
Results from confirmation testing: < 1ppm Non-detect for JP-8

Field Project #1
Location: North Central California
Treatment: Oxidizer w/fentons reagent
Volume of soil: 250 yd3
Contamination type(s): Diesel fuel/age of spill 1 year
Average level of contamination: 370 PPM/Used oxidizer set at 400ppm balance
Peak levels of contamination: Unknown
Elapsed time for project: 18 hours
Elapsed time after completion prior to collecting confirmation samples: No waiting period
Number of confirmation samples collected: Six(6)
Results from confirmation testing: <1 ppm ND for diesel and BTEX for all samples (sensitivity: 1 ppm).

Field Project #3
Location: California North Coast
Treatment: Bio Enhanced Surfactant
Volume of soil: 1915 yd3
Contamination type(s): Gasoline and MTBE
Average level of contamination: 306 PPM gasoline; 31 PPM MTBE
Peak levels of contamination: Measured at over 7000 PPM, free product some sections where trapped in plastic
Elapsed time for project: Fifteen days
Elapsed time after completion prior to collecting confirmation samples: Twenty days
Number of confirmation samples collected: 38
Results from confirmation testing: Non-detect for gasoline in all samples (Sensitivity: 1 ppm). Non-detect for MTBE in all samples (Sensitivity 100ppb). Sixteen samples showed varying levels of BTEX (Sensitivity at 100ppb), the highest of which was 280 PPB total Xylenes in one sample. After two weeks of additional residence time at flag locations retest proved non-detect.
