Document, Report, or Work plan Review - other |
Preliminary Assessment dated June 26, 2007. Evidence of past military use includes the remaining empty concrete structures. A pile of lead-acid batteries (approximately 20) is present in one searchlight bunker. At least one battery is upside down and one has a crack in the casing. A UST is located at the site. UST partially exposed and vent pipe disconnected. No groundwater migration pathway present. Any releases could travel downgradient to the ocean. Soil layer on Barwell Island is very thin, given the rock outcropping and exposed cliffs. |
