Johnson Controls Wastewater Treatment and Hunter's Point Remediation Projects win 2013 AAEES Excellence in Environmental Engineering Awards

Projects win Grand Prize in Industrial Waste Practice and Honor Award in Research

April 25, 2013

CAMBRIDGE, Massachusetts—Two CDM Smith projects have received 2013 Excellence in Environmental Engineering awards from the American Academy of Environmental Engineers and Scientists (AAEES). In the industrial waste practice category, the Johnson Controls Inc. integrated stormwater and wastewater treatment facility received the Grand Prize. The project was also selected for the W. Wesley Eckenfelder Industrial Waste Management medal. In the research category, CDM Smith’s innovative remediation research and development at the former Hunter’s Point Naval Shipyard was recognized with an Honor Award.

CDM Smith designed and constructed the integrated stormwater and industrial process wastewater treatment system at Johnson Controls' new lead-acid battery recycling center in Florence, S.C., USA. This facility employs modern environmental controls to protect the public and the environment, allow for water reuse and reduce dependence on municipal supplies.

The state-of-the-art, environmentally friendly facility treats process wastewater, generated by the recycling center, with chemical pretreatment, clarification and sand filtration to meet permit limits for safe discharge to the city sewer system. A portion of the treated effluent is reused in production, with excess discharged to the publicly owned treatment works.

Stormwater from roofs and process-related non-roofed areas is collected and stored in a 2.3-million-gallon high-density polyethylene-lined impoundment. Impounded water is treated for potential lead contamination with sand filtration and then reused as scrubber make-up water, which surpasses existing groundwater quality, displaces groundwater withdrawals and reduces spray nozzle maintenance.

CDM Smith successfully addressed several project challenges, including a very aggressive schedule, complex site hydrology, treatment of variable wastewater and a strict budget. CDM Smith’s fast-track delivery for the entire system, including the treatment building, allowed it to be completed within 10 months and before startup of the recycling center. CDM Smith also provided startup services, operator training and an operations & maintenance manual, and continues to provide supervising operators.

In collaboration with Naval Facilities Southwest Division (NAVFAC), CDM Smith conducted innovative research and development work to remediate sections of the former Hunter’s Point Naval Shipyard in San Francisco. The project enabled a property transfer to the city in 2013 that will revitalize the area.

The Hunters Point Naval Shipyard, located along San Francisco’s southeast waterfront, was closed and abandoned in 1982. The area was declared a Superfund site in 1989, and placed under the Navy Base Realignment and Closure Program in 1991 for remediation and release to the city for redevelopment. Years of industrial use had left behind a combination of hazardous compounds—chlorinated ethenes, ethanes and benzenes as dense non-aqueous liquids (DNAPLs)—contaminating soil and groundwater. Due to the site’s proximity to the bay and the city’s residents, the DNAPLs posed unacceptable risk that threatened the long-awaited transfer of an adjacent property to the city of San Francisco for redevelopment.

CDM Smith worked with NAVFAC to identify design elements that maximized synergies between in situ thermal remediation and in situ bioremediation. The innovative approach provided cost-effective, successful cleanup within an aggressive 18-month timeframe, ultimately allowing the city’s long-awaited redevelopment plans to move forward.

CDM Smith provides lasting and integrated solutions in water, environment, transportation, energy and facilities to public and private clients worldwide. As a full-service consulting, engineering, construction, and operations firm, we deliver exceptional client service, quality results and enduring value across the entire project life cycle.
