Status of NPS CERCLA Activities

2007/2008 Remedial Investigation Findings
Possible risk associated with contaminants in soil
Impacts to surface water unlikely
Impacts to groundwater unlikely but required confirmation
2012 Feasibility Study completed to review alternatives to address

soil contamination

2013 NPS issued Proposed Plan - Soil Cap
Also in 2013, NPS initiated additional groundwater investigation to

confirm 2007/2008 Remedial Investigations findings

Based in part on public comments received, the Proposed Plan

deferred until additional investigations completed

Future Use

Kenilworth Park South

NPS will manage as a Natural Resource Recreational

Area (wildlife habitat and recreational use such as birder, cyclist, walker [Anacostia River Trail Use]). Kenilworth Park North

Active recreational use (i.e. athletic fields) will

continue.
