A variety of wastes are generated during times of site investigation. Investigative Derived Wastes ("IDW"), are often smaller quantities of liquid and solid wastes requiring both consolidation and detailed waste paperwork processing for offsite disposal.

Oftentimes site restrictions or regulatory requirements do not allow for the long-term storage of IDW on-sites and these wastes need to be dealt with both efficiently and in compliance with all waste regulations. Lewis Environmental has been working alongside site developers and their environmental engineering consultants for decades providing the expertise and small project details that efficiently manage these waste streams and remove them from the site in a timely and responsible manner.
