Project Name: Borough of Butler, Site Remediation in Preparation for Redevelopment

Location of Work: Butler, New Jersey

Work Scope: Excel Environmental Resources, Inc. (Excel) was retained by the Borough of Butler to perform a Preliminary Assessment (PA) and subsequent Site Investigation (SI) in order to facilitate the Borough's intended acquisition and redevelopment of a property as part of a plan for revitalizing the downtown area of Butler. Funding for the project in the amount of $100,000.00 was obtained by Excel on behalf of the Borough of Butler, from the Hazardous Discharge Site Remediation Fund (HDSRF). Following are some key aspects of the project:

• As a result of the PA, Excel identified several areas of potential environmental concern (AOC) that were evaluated during a subsequent SI. In an effort to satisfy contract-imposed timeframes established on behalf of a prospective third party developer, Excel accelerated the performance of the SI, with NJDEP approval prior to completion of the PA to facilitate the proposed redevelopment project for the site.



• The SI was performed using a phased approach to streamline investigation activities and to efficiently utilize the project funds to collect as much information as possible in an effort to steer the project towards completion.



• The first phase of the SI was conducted to verify surface and subsurface soil quality, including potential Historic Fill, and groundwater quality at the site.



• Based on the initial SI activities, a supplemental investigation was conducted as part of a second phase of SI to evaluate lateral and vertical soil quality, further evaluate whether constituents reported at concentrations above the NJDEP soil cleanup criteria during the initial SI were AOC-specific or associated with contaminated Historic Fill, and to verify groundwater quality at the site through installation and sampling of monitoring wells.
