Understanding and following the selected procedure is critical in obtaining usable and defensible data. Our team of qualified samplers have experience in collection of multiple media types as follows:​

​

• Groundwater and surface water sampling utilizes specialized equipment and expertise to control flow, reduce impact to volatile compounds during collection, reduce interferences, and ensure the matrix being sampled is stable and represents the zone or area of interest. 

• Lead-based paint sampling for characterization of building to determine disposal requirements (unregulated landfill vs RCRA regulated landfill), treatment (paint removal), demolition requirements (training, monitoring, dust control), Sampling options include on site screening or offsite testing for total lead or the toxicity characteristics leaching procedure.

• Soil sampling methods are dependent upon multiple factors such as sample depth, location of contaminated area, soil matrix, etc. Sampling utilizes various methods such as shovels, spoons, hand augers, excavators, and drilling and follows the ADEC and EPA guidance documents.

• Drum waste sampling techniques are dependent on location, condition of drum, owner knowledge, toxicity of contents, safe practices, logistics for transport, and disposal option. This may also involve characterization for profiling and generation of manifests.

• Sediment sampling can be tricky since this matrix is beneath a water body such as a wetland, pond, river, etc. Another element to consider is the percent moisture in the sample since the lack of solid material elevates the method and reporting limits used to meet established cleanup limits or standards. Methods are established during the data quality objective phase to maximize ability to meet regulatory criteria.

• Wipe samples are collected to characterize a surface area for chemicals such as PCBs. 

• Field screening procedures are used to reduce cost and number of samples required for offsite testing and to meet state criteria.
