Case study - GRO in soil at gasoline UST site
These case studies show the performance using Sitelab’s UVF-3100 analyzer testing gasoline range organic hydrocarbons. This includes benzene, xylene, BTEX and other volatile petroleum compounds in the GRO or VPH C6 to C10 hydrocarbon range. When calibrated using Sitelab`s GRO calibration kit (CAL-025), the UVF analyzer produces test results that correlate well to laboratory regulatory methods using GC instrumation. Both the UVF-3100A and UVF-3100D models are fitted with special optical filters sensitive to...
Case study - EDRO in soil at wharf remediation site
Sitelab Calibration Kit CAL-042 is used for EDRO analysis. The UVF-3100 detects hydrocarbons in the C10-C36 range.A Licensed Site Professional (LSP) used Sitelab to investigate a commercial waterfront property, contaminated with a plume of LNAPL resulting from fuel tanks which once stored heating oil, diesel and gasoline dating back to the 1950s. The site is in Massachusetts, where laboratories are required to test TPH in soil using the Mass DEP’s method for Extractable Petroleum Hydrocarbons (EPH).EPH is...
Case study - Texas crude oil in soil sites
Sunset Well Service, Inc. is an environmental contractor located in the Midland/Odessa area of Texas. They use their UVF-3100D analyzer to help excavate and remediate soils contaminated by produced water and crude oil. Laboratories in Texas test TPH using the TX 1005 GC-FID Method. This method is similar to U.S. EPA Method 8015M, but reports the GRO, DRO and ORO fractions separately.Soils from two spill sites were split and sent to a certified laboratory for confirmation analysis and the field results correlated...
Case study - Nigeria crude oil in soil site
Safic Technologies, Ltd. - Port HarcourtA pilot study was conducted testing soil samples collected from a pipeline spill. Split samples were sent to Sitelab for EDRO analysis and results were the same. Samples were also sent to a Nigerian lab and a highly reputable lab in the United States for confirmation. After testing the samples a second time, the American lab got better results. Labs from different countries report TPH in different carbon ranges.EDRO Calibration Kit Product No. CAL-042 Available in...
Case study - UVF and LIF used together at oil refinery site
A former oil refinery in Kansas has a 100-acre size plume of oil. The NAPL is commingled with gasoline, diesel, crude oil and other petroleum products. An environmental consultant used Sitelab’s UVF to field screen hundreds of soil samples for EPH C11-C22 aromatic hydrocarbons. Split samples sent to a confirmatory lab directly correlated (see graph).Laser Induced Fluorescence (LIF) had also been used on this site. LIF is sensitive to aromatic hydrocarbons, but results are qualitative (as % response). The...
