Site Investigation and Remediation

Keeping a finger on the environmental pulse

As environmental regulations and treatment technologies evolve, Brown and Caldwell helps clients adjust to and address these changes. Our scientists and engineers are in-tune with some of today’s biggest environmental challenges such as emerging contaminants, water reuse, site closure, and remedial construction to develop cost-effective and timely solutions.

Holistic remedial approach restores wetlands and provides public access

To address over 40 areas of concern (including NAPL) at a former chemical manufacturing site, BC developed a holistic remedial strategy that balances economic redevelopment, ecological restoration, and public access. A focused and fast-track pre-design investigation led to the closure, sale, and redevelopment of over 35-acres of the site. BC efficiently obtained permits and agency approvals to permanently fill freshwater wetlands for construction of the hydraulic barrier wall and cap. Wetland mitigation, ecological restoration, and construction of an eco-park transformed this site from an unusable brownfields site to a public park. The NJDEP Case manager described the site as “the perfect brownfields site.”

Value engineering saves $ throughout design

BC provided permitting, design, engineering services for the 575-acre American Cyanamid Superfund Site. BC designed a site-wide groundwater treatment facility on a small footprint to treat the contaminated groundwater with a flow capacity of 500-gpm. This highly complex, Superfund project was streamlined through regulatory management, an integrated constructability evaluation, and value engineering that will potentially save the client $5.5 million.

Strategic negotiations save client millions

BC is helping a confidential client remediate metals-impacted soil within a 70-acre area. BC negotiated with the local agency for a clean-up value that saved an estimated $400,000 on soil remediation. The team helped with negotiation that supported cost savings to the client of an additional $1 million during the first phase of remediation, and an estimated $3 million for subsequent remediation phases.

Design-build approach succeeds in eliminating VOC mass

BC's turnkey design-build approach eliminated a source-area chlorinated volatile organic compound (CVOC) mass that had thwarted previous remediation attempts by others. Excavation and dewatering to 30-feet below grade was completed on time, within budget, and incident free despite being conducted in a complex geologic environment on a compact urban site.

Turnkey approach delivers timely DNAPL response action

Reacting to an immediate response action requirement due to DNAPL detection, BC designed and constructed a targeted shallow soil excavation for DNAPL removal and an automated extraction/recirculation system for recovery of deep DNAPL in groundwater. Value engineering and field-based decisions streamlined the project, priced it competitively, and controlled costs and risks. The highly compressed delivery helped meet regulatory timeframes and complete the project under budget and without compromising health and safety.

Expedited delivery intercepts and contains runaway plume

To intercept a fast moving, non-attenuating CVOC plume, BC designed and constructed a deep groundwater hydraulic containment system and mile long transmission forcemain under a fixed-price delivery. The system pumps and conveys up to 75-gpm to a treatment plant and reinjects using a double cased reinjection well capable of up to 36-gpm injection. Crossing private properties and directionally drilling the forcemain underneath a state highway, BC delivered ahead of schedule, under budget and incident free. The plume arrived at the extraction well boundary and was contained by the system that protected residents from a potential vapor intrusion risk of the plume.

Continued closure success at Guam disposal facility

Situated on 63-acres of land, the Ordot Dump had been the sole disposal facility for Guam’s waste since the 1940s. BC led the investigation and design team that developed the closure plan and ended an era of long-running environmental issues, including releases of contaminated leachate into local water bodies, methane gas emissions, and odor problems. BC is continuing post-closure activities by performing inspections, O&M, and implementation of the site post closure monitoring plan.
