| dc.description.abstract | Under contract with the US Army Corps of Engineers, New England District (USACE-NAE), AMEC Environment & Infrastructure, Inc. (AMEC) conducted a sixth and seventh round of indoor air and sub-slab vapor sampling at the Frances C. Richmond Middle School (RMS) at 63 Lyme Road, Hanover, New Hampshire on December 30 and 31, 2014 and January 19 and 24, 2015. AMEC has prepared this data report for the USACE-NAE under contract number W912WJ-11-D- 0005 Task Order 0004. Sampling was performed at 15 locations for indoor air samples, 9 locations for sub-slab samples, and 4 outdoor ambient air locations. During the December 2014 sampling event, sampling was performed using Bottle-VacTM sample containers with analyses performed using the Inficon Hapsite ER portable gas chromatograph with mass selective detector (GC/MS). Analysis of equipment blanks indicated the sampling equipment was contaminated from previous use and the data was rejected. A re-sample event was performed on January 19, 2015 using summa canisters. An assessment of chemical data showed that trichloroethene (TCE) was detected in indoor air samples. TCE was detected from 0.28 micrograms per cubic meter (µg/m3) to 2600 µg/m3 in the indoor air. The result from the Cafeteria sample exceeded the NHDES commercial screening levels for TCE and the SAU 70 Superintendent was immediately notified on January 22nd, 2015. TCE was detected in ambient air samples from 0.35J to 58 µg/m3. The ambient air sample located at the south end outside of the cafeteria was the location of the most elevated TCE result. The Hapsite GC/MS was deployed to the Hanover Middle School on the evening of January 22nd and was used to evaluate indoor air conditions. The Hapsite analyses indicated that indoor air throughout Hanover Middle School did not have detectable TCE concentrations. A confirmatory sample event was performed on January 24, 2015 using summa canisters. An assessment of chemical data showed that TCE concentrations in the indoor air ranged from ND to 0.24J µg/m3. TCE concentrations ranged from ND to 7.5 µg/m3 in sub-slab vapor. TCE in the ambient air samples ranged from ND to 0.44J µg/m3. None of the indoor air samples collected showed values approaching the interim action levels for TCE. There were no sub-slab or indoor air concentrations exceeding NHDES commercial screening levels for TCE in samples collected on January 24th. | en_US |
