ENTACT remediated a former factory site – slated for residential and retail redevelopment – that was impacted by multiple contaminants, including arsenic and lead. The property is in a dense urban area, divided by a city street and bordered by city transit and right of ways (ROWs).

The scope of work included onsite treatment and off-site disposal of 44,000 tons of non-hazardous material; onsite stabilization and off-site disposal of arsenic, volatile organic compound, and contaminant-impacted soils as much as 16 feet below ground level; excavation and off-site disposal of chromium-impacted hot spot areas; utilization of benching and trench boxes for excavation support along the street, transit, and ROW areas; and dewatering and water treatment.
