Onsite Testing
Accurate real time laboratory results during an environmental site investigation or remediation can be an invaluable tool for directing field work and ensuring adequate information is collected. Using ultraviolet fluorescence (UVF) and x-ray fluorescence (XRF) technologies AEL is able support your environmental field work with high quality laboratory data for screening the most prevalent organic and inorganic compounds in soil and water. In addition, when data is downloaded into our GIS based data management and analysis software, real time site-wide data maps and cross-sections can be generated to show contaminant trends and information gaps.
UVF Analysis
UVF analysis can be completed in both soil and water. Target compounds of UVF testing include petroleum hydrocarbons (PHC), total BTEX (Benzene, Toluene, Ethylbenzene, and Xylenes), polychlorinated biphenyls (PCB) and polycyclic aromatic hydrocarbons (PAH). Detection limits vary depending on dilution but generally meet the most stringent cleanup criteria.
XRF Analysis
For XRF analysis target compounds include 15 “standard” elements that can be expanded to 24 by changing the radioactive source. Only effective for use in soil or sediments, detection limits vary based on site conditions and soil type. For priority compounds such as lead and arsenic, detection limits meet most cleanup criteria.
Onsite Analysis Benefits
Screening level results can be available in 5 minutes or less per sample. The maximum number of samples analyzed and reported generally averages 40 to 50 samples per day. Our mobile laboratory is completely self-contained and comes equipped with the most commonly required sampling and analytical supplies. Readily transportable, our mobile lab allows analytical work to be completed at remote sites on a worldwide basis.
Per unit analytical costs vary on sample volume and target contaminant but are much less than comparable laboratory charges. Field support and travel expenses are extra but are similar to those normally required in completing site work.
