 TD-500D is a hand held, battery operated field analyzer, which is highly sensitive to heavy fuel oil, waste oils, crude oils, bitumen and coal tars:





Monitoring Produced Sand on Offshore Oil Platforms for Overboard Discharge

Location: offshore oil platform in the South China Sea, Malaysia.  Produced sand is generated from oil and gas production and must be disposed off-site or dumped overboard.  Customer uses TD-500D to help monitor and treat produced sand contaminated with crude oil in order to meet their 10,000 ppm (mg/Kg) discharge limit. 


Sand is tested for hydrocarbons using methanol.  If the use or transport solvents are prohibitive, a surfactant can be used as a substitute, available from Sitelab's partner Turner Designs Hydrocarbon Instruments, Inc (below).

PAH Evaluation Testing Asphalt in France
New regulations by the European Union require laboratory testing for polyaromatic hydrocarbons when recycling or disposing old tar and asphalt from road planings.  Sitelab's UVF-3100D and TD-500D analyzers are very sensitive to the same PAHs detected by the certified laboratory methods.  An evaluation study performed by ESITC shows good accuracy testing PAHs compared to EPA Method 8270 by GC/MS performed by four certified laboratories.

Testing Benzo[a]Pyrene at Bioremediation Facility
King County Department of Transportation in Seattle monitors PAHs to help determine if their bioremediated soil meets or exceeds state cleanup levels for Benzo[a]Pyrene.  The Street Waste Alternative Program (SWAP), manages 10,000 to 15,000 cubic yards of material a year, generated from road maintenance operations.  The soils consist of catch basin sediments and street sweepings which are composted and treated.  The processed soils are tested to ensure that any pollutant levels are within acceptable concentrations prior to reuse for on-site low risk applications. See case study
Testing TPH at Lumwana Copper Mine, Zambia
Equinox Minerals operates the biggest copper mine in Africa, located at Lumwana in Northwest Province, Zambia.  Open pit mining methods are used to access the ore which is hauled to the process plant where it is crushed and processed into final concentrate.  Scientists used Sitelab's hand held TD-500D analyzer and test kits to measure hundreds of soil samples contaminated by petroleum hydrocarbons resulting from their mining operations.

Total Petroleum Hydrocarbon Analysis at New Jersey Brownfield Site
U.S. EPA Region 2 conducted a pilot study for a Brownfield site in Milltown, New Jersey, as part of the TRIAD program.  The site had a long history of different uses with various petroleum contaminates.

Sitelab's TD-500D analyzer and TPH-Oil calibration kit were evaluated testing soil samples collected throughout the site.  Results correlated well to split samples sent to a certified lab using EPA Method 418.1 by Infrared.

PAHs in Creosote at Marina Redevelopment Site

A developer was excavating a wharf on a lake in upstate New York, which was contaminated with creosote soaked logs and soil.  Creosote contains chrysene, benzo[a]pyrene and many other polyaromatic hydrocarbons that are regulated by NY DEC.  The TD-500D was used to check PAH concentrations in order to help segregate which soils could be reused on-site and which soils had to be trucked away to a costly landfill. 

TPH in River Sediments Contaminated by Coal Tar at Former MGP Site

A contractor was cleaning up river sediments contaminated by a former manufactured gas plant in Colorado.  Since the early 19th century, these plants converted coal into gas used for lighting and heating.  The residual coal tars and oils produced on these sites contain high concentrations of PAHs and TPH.  Like many MGP sites, this site contained a subsurface plume of DNAPL oil (dense non aqueous phase liquids).

Coal tar collected from the site's plume was sent to Sitelab for TD-500D analysis and used to prepare a calibration standard for TPH measurement.
