Urban Site Management: Niles Union Pacific Site Phase II Remediation Project


In a very limited access site next to an established neighborhood, PSEC remediated a hydrocarbon and metals contaminated site, while accommodating the existing encroachment and use as a parking lot. Over an almost two year period, the excavation of over 28,000 tons of material was accomplished in a “hopscotch” pattern, allowing the site to continue to operate.
