Testing Drinking Water From Jet Fuel Spill, Pearl Harbor, Hawaii
Winter 2022: The U.S. military and their contractors are using Sitelab UVF-TRILOGY analyzers, model 7200-004-FNGP, to monitor hydrocarbons in drinking water samples.  In late November 2021, a large fuel leak occured at the Red Hill tank farm and contaminated the water supply serving the base.  Thousands of homes were effected. 

The U.S. Navy is working closely with the Hawaii Department of Health, U.S. Environmental Protection Agency and the U.S. Army to restore safe drinking water to Joint Base Pearl Harbor-Hickam housing communities through sampling and flushing, and the recovery of the Red Hill Well. 

“This is really exciting technology, with a complete test in 15 minutes,” said Lt. Cmdr. Richard Forney, Naval Facilities Engineering Systems Command Engineering Working Group Rapid Response Team officer in charge. “The Navy has made an investment in this technology to provide residents with the results as fast as possible.  Rather than losing time to shipping, we’re spending that reclaimed time on fixing any problem we may find, and getting families home.” 

The Sitelab UVF-TRILOGY Benchtop Analyzer uses ultraviolet fluorescent technology to offer accurate sample results.  “The TPH analyzer zeroes in on hydrocarbons, which allows a faster result to be delivered to the resident to validate that the Navy is providing clean, safe water,” said Forney.

  Water Quality Study using UVF to Detect Hydrocarbons and Natural Organics
Merrimack River, Massachusetts: This study was performed to help support a customer looking to distinguish if surface water contains oil sheens or bio sheens using their UVF-Trilogy analyzer.  Bio sheens can look like oil sheens but are naturally occurring and are not caused by petroleum spills.  Water high in organic content from algae, decayed plant matter or from bacteria in stormwater and combined sewer overflows (CSOs), can also be detected without the use of solvent extraction.

To mimic the types of conditions they have, a variety of samples were analyzed locally by Sitelab using it’s two UVF instruments.  The Merrimack River is often polluted by discharges of sewage and features a large number of marinas and commercial fishing boats where spills of gasoline, diesel and oil could occur.  No oil or sheens were found, but the river did exhibit a drop in water soluable organics from Haverhill to the Atlantic Ocean, likely due to a CSO event from heavy rainfall the week before.    

The Merrimack River Watershed Council is a local non-profit which monitors the river and is a good resource for it's condition.  Visit: MERRIMACK.ORG

  U.S. EPA Grant Award: Chesapeake Bay Trust
2019-2022: Sitelab Corporation is working with the Chesapeake Bay Trust, DOEE and the U.S. EPA in Washington, DC 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 tar, ethylene cracked residue 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 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.

"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
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.  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.
