Sampling & Analysis

When a proper waste determination cannot be made using material safety data sheets (MSDS) or generator process knowledge, then sampling and analysis must be conducted. Prior to sampling, drums and containers must be inspected, staged, and opened by an environmental waste specialist. Inspection is the process of observing and recording the structural integrity of containers and any physical characteristics which might be pertinent to determining the drum’s contents. During the staging process, drums are grouped according to waste classifications determined during the inspection. The final step is the opening of the containers. This can be done by either manually or remotely.

When performing waste sampling the following procedures should be followed:

  1. Label the sample container appropriately and record all pertinent information along with a chain of custody form. Double bag the sample container in resealable plastic bags.
  2. Put the double bagged sample into a larger lined DOT approved container. Make sure there is enough cushioning material (absorbent, vermiculite, rags, etc.) in the DOT container so that if the sample breaks, it will be absorbed and not leak.
  3. Finalize the chain of custody form for each sample container and place the chain of custody with the sample container.
  4. Lock and seal the shipping container and use a suitable mode of transportation for the type of hazardous waste involved.

When samples are collected from drums, they are considered waste samples and thus should be left in the original sample state without preservatives eliminating any possibility of reaction. However, samples need to be stored on ice or in a fridge away from sunlight to reduce the potential for a reaction.

WasteXpress has highly qualified field technicians that can inspect, stage, open, and sample contents within drums or containers to submit to a certified laboratory for proper analysis. Upon receipt of analysis, our account representatives will go over the results with the generator and then work with them to identify the best route for disposal.
