DOWNLOAD EBOOKThis report evaluates the methods of analysis that can be used with the Hanby Test Kits for assessing the total petroleum hydrocarbon (TPH) contamination in environmental matrices. This field screening technique is based on the colorimetric analysis of petroleum products in soil and water matrices, following a solvent extraction and a Friedel-Crafts reaction. The methods include visually comparing the sample to reference photographs, and two spectrophotometric (H.E.L.P. Mate 2010 and 2000) systems designed to establish discrete values. To test these field screening techniques, 90 field and quality assurance (QA) samples were obtained. Both of the spectrophotometric methods experienced instrumental problems, so that fewer than 60% of the samples distributed could be analyzed on-site. Ultimately, the H.E.L.P. Mate 2010 was dropped from the evaluation altogether. Furthermore, because of these complications, no TPH values were reported during the field exercise. The results yielded by the visual and H.E.L.P. Mate 2000 methods were compared for the QA samples; the visual technique was more reliable for showing the presence and estimating the quantity of TPH contamination.

DOWNLOAD EBOOKGround water sampling and analysis are large efforts in terms of manpower and cost. The primary water contaminants from petroleum sources are the aromatic constituents due to their solubility in water. A commercially available field test kit (Hanby Analytical Laboratories, Inc.) was evaluated for application of on-site detection of low level contamination of water by aromatics. The results obtained using this kit are compared with those obtained in the laboratory using gas chromatographic methods.

DOWNLOAD EBOOKA new screening method for fuel contamination in soils was recently developed as American Society for Testing and Materials (ASTM) Method D-5831-95, Standard Test Method for Screening Fuels in Soils. This method uses low-toxicity chemicals and can be sued to screen organic- rich soils, as well as being fast, easy, and inexpensive to perform. Fuels containing aromatic compounds, such as diesel fuel and gasoline, as well as other aromatic-containing hydrocarbon materials, such as motor oil, crude oil, and cola oil, can be determined. The screening method for fuels in soils was evaluated by conducting a Collaborative study on the method. In the Collaborative study, a sand and an organic soil spiked with various concentrations of diesel fuel were tested. Data from the Collaborative study were used to determine the reproducibility (between participants) and repeatability (within participants) precision of the method for screening the test materials. The Collaborative study data also provide information on the performance of portable field equipment (patent pending) versus laboratory equipment for performing the screening method and a comparison of diesel concentration values determined using the screening method versus a laboratory method.
