Overview

LiRo-Hill performed a site investigation and remedial alternatives report for the former Spaulding Fibre Plant site in Tonawanda, New York. The work was conducted with funding support and oversight from the New York State Department of Environmental Conservation (NYSDEC) under their Environmental Restoration Program (ERP). The project scope included comprehensive characterization of soil, groundwater and building contamination at a 20-acre manufacturing facility.

About the Project

In order to determine the nature and extent of subsurface contamination, LiRo-Hill developed comprehensive site investigation work plans. The plans incorporated the findings of a review of the plant history, focusing sample locations at historical process areas, building development lines, sewers and drainage systems. LiRo-Hill also proposed preliminary passive soil gas and geophysical studies to focus the subsurface sampling program. LiRo’s work plans conformed to the NYSDEC ERP’s requirements and included detailed quality assurance and health and safety plans. For the site investigation report, LiRo-Hill developed a list of regulatory and risk-based contaminant level screening criteria to support remedial decisions; conducted a health risk evaluation; and developed a site conceptual model for evaluating the location and migration of site contaminants.

Outcome

Based on the results of the site investigation and risk evaluations, LiRo-Hill determined the need for remedial measures and performed an evaluation of remedial alternative which were applied at the site. The alternatives involved source control and other necessary response actions to recover, collect, remove and destroy, control and/or contain chemical contaminants released from the site. A detailed analysis of each selected alternative weighed protection of human health and environment, compliance with regulatory criteria, implementability, reduction of toxicity, mobility or volume, short-term effectiveness, long-term effectiveness, and cost. The remedial alternatives report culminated in a selected site remedy.
