  U.S. EPA Grant Award: Chesapeake Bay Trust
2019-2021: Sitelab Corporation is working with the Chesapeake Bay Trust and the U.S. Environmental Protection Agency to develop and create a certification program testing the PAH content in parking lot sealcoats.  Materials used to manufacture sealcoats vary; most in commercial use are made with coal tars, ethylene cracker residues or are asphalt-based.  Manufacturers who participate will know if their product meets a 1,000 ppm (Gold) or 10,000 ppm (Silver) regulatory limit. 

An ongoing list of certified sealcoat products will inform the public of the general concentration of PAHs in each manufacturer's product.  This information will be used for communities that want to ban sealcoats made with high concentrations of PAHs.  Stay tuned to this webpage as more information becomes available.

  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.

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.

  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.

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  »SEE FEATURE STORY



     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

    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.  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.

  Sitelab Evaluated by BP's Deepwater Horizon Response Team

August 2010: Summary of the final evaluation report for Sitelab's portable petroleum contamination test kits states:

Key Conclusions: Established technology for detecting oil in both water and soil applications.  We have communicated these results to the Deepwater Horizon MC252 Incident Command Posts with a request that they give consideration to the use of your technology."

  Concerned about the Gulf Coast Oil Spill?

 Warren Nance of Gulfport, Mississippi, is a local resident who has started a grass-roots effort to monitor the pre-impact and post-impact effects of crude oil contamination resulting from the BP oil spill in the Gulf of Mexico.  Samples were carefully collected and shipped to Sitelab for laboratory analysis.

Samples of sediment, water, cord grass and mussels were collected from a marsh located several miles north of Dauphin Island, Alabama, which was not yet polluted. Samples of tar balls and dispersant washed up on the beach were also collected and tested.  See image to right for details. 

"I needed a fast, reliable and affordable system for baseline monitoring of TPH levels in plant, sediment, water and animal samples taken from the Biloxi Marsh in Louisiana.  Sitelab took a personal interest in my project and sent me a comprehensive analysis report one day after they arrived at their lab.  I highly recommend their service."  Nance Enterprises, Inc., Gulfport, MS

Gold Mine Sites in Yellowknife, Canada

The Department of Indian and Northern Affairs Canada (DIAND) is using Sitelab test kits to investigate and cleanup old, abandoned gold mine sites throughout the Northwest Territories.  Most of the mines are contaminated by diesel fuel once used to provide heat and power in the remote artic conditions.

Like other customers in Canada, DIAND uses Sitelab's GRO and EDRO calibration kits with the UVF-3100 analyzer.  Results correlate well to the F1, F2 and F3 fractions in TPH for detecting the gasoline range, diesel range and oil range hydrocarbons, which are similar to U.S. EPA method 8015 using GC instrumentation.






Monitoring contamination from crude oil and bitumen is also popular in Canada.

  Sediment Remediation with U.S. Army Corp of Engineers

A contractor working for the U.S. Army Corp of Engineers used Sitelab on-site in order to clean up murky sediments in a fire pond once used by the Navy.  The pond had been contaminated by waste oils, including a recent accident involving a large spill of diesel fuel from an abutting railroad yard.  Engineers paddled by boat and used a probe to collect borings on the pond bottom, which were carefully drained and then tested for diesel range hydrocarbons.
