According to the United States Environmental Protection Agency, a Brownfield is a property that is environmentally contaminated -- or perceived to be contaminated -- and now vacant, abandoned, idle, or underutilized due to the real or perceived contamination. By using a Pollution Risk Services comprehensive liability transfer agreement (CLTA), real estate sites designated as Brownfields are able to be remediated and returned to regulatory compliance. Though the rules and regulations surrounding Brownfield remediation and redevelopment are often cumbersome, Pollution Risk Services has the experience to efficiently and effectively navigate the obstacles to bring the remediation to a successful conclusion. Once returned to compliance, Pollution Risk Services is able to undertake the redevelopment and return the site to economic and community usefulness.
