 Concerned about sealcoats used on streets, parking lots and driveways?
     There is growing concern - and regulations in the works - over the use of sealcoating products due to their high PAH content.  In the United States and elsewhere, most sealcoats are made from coal tar which can be toxic to aquatic life and threaten public water supplies from rain and runoff.  Sitelab can be used to quickly check the concentrations of polycyclic aromatic hydrocarbons and determine if it's made from coal tar or alternative petroleum based black top sealants. 

     Residents in the Town of Pomfret, Connecticut, submitted a sample for analysis from a street which had been sealcoated by coal tar.  The sealcoat was found on dog's paws, children's basketballs, shoes, car tires and lawns.  The neighborhood is concerned too about potential PAHs from dust getting into their homes, drinking water wells and scrapings from snow plows.  »SEE VIDEO FROM FOX61 NEWS which featured this story.

 Applications in Europe testing Asphalt for PAH content and Benzo[a]Pyrene
     New regulations by the European Union require laboratory testing for polycylic aromatic hydrocarbons (PAHs) when reclaiming or disposing old asphalt from road planings and pavement.   

    Sitelab’s portable UVF-3100D and TD-500D analyzers have similar sensitivity to these types of compounds. The equipment is easy to operate and samples can be tested in the field in less than five minutes.  Samples are extracted in solvent using disposable test kits and then measured on the instrument which is calibrated using Sitelab’s PAH calibration kit.  Results will directly correlate to certified laboratories using GC/MS methods.

    Total Petroleum Hydrocarbons or "TPH" is defined and detected differrently depending on where you're from.  What is GRO and DRO?  What is VPH and EPH?  How are they similar?  How are they different?

   This presentation describes how different laboratory methods exist from state to state and country to country.  In most cases, laboratories are using the same methods.  Yet even when labs perform the same analysis on the same samples, results can vary quite a bit.  The use of field screening methods and how they correlate to these different methods is important to understand.
     Download presentation    Learn how ultraviolet fluorescence and laser induced fluorescence tools are used together to better dilinate the impact and volume of oil below the ground. 

   This presentation highlights several projects where an environmental consultant uses Sitelab's UVF data to calibrate LIF data using UVOST and TarGOST from Dakota Technolgies, Inc.  This new technique was developed by Subsurface Environmental Solutions, LLC, who specialize in NAPL remediaton.
 
 
  Sitelab Corporation presents at 20th IPEC Conference, San Antonio, TX

    Do you work in the oil and gas industry?  The International Petroleum Environmental Conference (IPEC) focuses on environmental issues and solutions in exploration, production, refining and distribution of petroleum.  Presented by the University of Tulsa, this year marks IPEC's 20th anniversary and offers 3 days of technical sessions.  Topics include the latest developments in fracking, produced water, LNAPL, regulatory issues, remediation of hydrocarbon spills and many more!

 
 
 
  Discrimination between oil based drilling mud and crude oil
      Need to monitor drill cuttings in new wells to see if crude oil, drilling muds or both are present?  Drilling for oil using oil based mud (OBM) facilitates the drilling process but is often confusing for the mudlogging geologist.  An evaluation study was performed testing 8 samples for a customer in California.

   
"The equipment shows a clear distinction between the OBM and formation oil when extracted from their liquid state."  Horizon Well Logging, Inc.  »See Evaluation Report

    The types and quantities of aromatic h
ydrocarbons that exist in crude oil fluoresce very differently and at much higher intensity compared to oil-based drilling muds and their additives.   If drill cuttings require TPH analysis, either instrument is suitable.  But when used together, Sitelab's technology can detect how much and what type of hydrocarbon is present.  It can even estimate the API gravity in the oil or drill cuttings.

   Monitoring TPH in produced sand for overboard discharge
      New regulations are requiring oil companies to test and treat produced sand generated from oil producing wells prior to dumping it overboard from offshore oil platforms.  A customer in Malaysia working in the South China Sea is using Sitelab's TD-500D device to test samples for Total Petroleum Hydrocarbons (TPH) to help monitor their treatment process.  Their discharge limit of crude oil in sand is 10,000 ppm (mg/Kg).

    Methanol solvent is used to extract the samples using Sitelab's test kits.  In locations where the use and transport of solvents are prohibitive, a surfactant can be used as an alternative to methanol, which yields similar TPH results.  Sitelab's TPH-Oil calibration kit used with the TD-500D analyzer is available in methanol or the surfactant.  The equipment is easy to operate and produces fast, accurate measurements.


 
 
  Regulators encourage use of UVF in new UST program guidelines
      North Carolina's Department of Environment and Natural Resources (DENR), Division of Waste Management, has recently approved UVF technology for use in it's Underground Storage Tank Program.   

    "The utilization of a semi-quantitative field technology, such as UVF, which allows on-site confirmation of the presence and lateral and vertical extent of soil and groundwater contamination for a wide range of specific petroleum products (i.e., not only gasoline and diesel, but also degraded fuels and waste oil), is preferable.  Field-screening data should be evaluated to determine where a minimal number of final soil or groundwater samples should be collected (or which previously collected, split samples should be selected) for analysis in the laboratory."  Page 57, Use and Limitations of Field Screening, Guidelines for Assessment and Corrective Action (10/1/2012)

   "We evaluated more than one technology to implement the on-site PAH screening, but ultimately felt that Sitelab offered the greatest understanding of our data needs and more flexibility and interpretive power in your data output."  Customer/Project Manger  »Click for details

     Sitelab Corporation was hired by an environmental contractor to analyze 100 sediment samples collected from a post-dredge area covering a 1 mile stretch of river in Hammond, Indiana.  The data was used to determine which of the 25 sample locations would require further assessment.

   
    In 2012, J.F. Brennan will be installing a cap on the river bottom, which consists of a 12 inch layer of a sand and organoclay mixture.  The cap is designed to prevent future exposure and pathways of the impacted sediments left behin
d.

    Sitelab's PAH fingerprinting data, combined by sample location coordinates recorded by GPS, were used to map the sediment contamination.  Results revealed several "hot spots" and where fresher versus older crude oil exists in the river

  Field method for testing oil sheens on surface water using sheen nets
 

    A pipeline spill in Michigan contaminated a river with crude oil.  Almost one year later, oil sheens continued to be spotted on the river's surface, as do "bio sheens," which look like oil sheens but only contain biological, natural organic matter from leaves and other decomposing vegetation.

    The oil company's contractor collected samples from both contaminated and non-contamianted areas using sheen nets.  The nets were extracted in solvent and analyzed by Sitelab's laboratory for their GRO, DRO and PAH concentrations using the UVF-3100D and TD-500D analyzers together, as part of Sitelab's unique TPH fingerprinting method.  The oil sheen nets fluoresced similar to each other, while the bio sheen nets came up clean and non-detect.  Knowing the difference between the two will help improve monitoring and cleanup.

  U.S. Gulf Coast Oil Spill, 1-Year Later:
 

    In April 2011, Sitelab received a group of samples collected from Perdidio Key in Pensacola, Florida.  The samples included beach sand and several fragments of tar balls washed ashore resulting from the BP oil spill from one year before.  Beach samples were collected from the surface down to two feet deep, at both high tide and low tide in the same area where clean up crews made their daily visit.

     The samples were analyzed by Sitelab using our UVF-3100D and TD-500D instruments.  Results show the tar balls did not appear to leave any residual oil in the sand.  Despite the distance and time spent at sea, these tar balls fluoresced very similar to other tar balls tested by Sitelab.  This report highlights results from different sites along the Gulf of Mexico.

Want to check octane at gasoline stations?

    Ever wonder if the gas you're putting in your car is legit?  That you pay for premium, super unleaded, but only get regular unleaded gas instead?  Sitelab has developed a quick, easy to use method for testing different grades of octane in commercial gasolines.  The higher the octane, the greater percentage of volatile aromatic hydrocarbons are added, which produce linear, higher fluorescence responses on the UVF-3100 analyzer.  Although UVF does not directly measure the octane itself, the data generated can be used for screening gasoline samples from one another in the field.  Octane can then be accurately estimated using Sitelab's unique software algorithms.  Results only take a few minutes and correlate well to the (R + M)/2 method.
