An Environmental Indicator inspection occurred at the Brooks Instrument facility on April 21, 2009 with a report forthcoming that should enable EPA to determine whether human exposures to contamination and migration of contaminated groundwater are under control at the Facility. The 2008 groundwater monitoring report concludes that trichloroethene (TCE) concentrations in groundwater have decreased or stabilized during the reporting period, whereas tetrachloroethene (PCE) concentrations have risen slightly. Maximum concentrations of TCE and PCE for this period were 27 ug/L and 19 ug/L, respectively.
The Facility entered into PADEP’s Act 2 Land Recycling Program in February 2007.
The 9.2-acre location was initially developed in 1935 as a textile mill. The Brooks Instrument Division of Emerson Electric Company has occupied this location since 1957 and manufactures and assembles analytical and electrical flow meters. Emerson Electric sold the Facility in December 2007 but retains ownership of the remediation activities of the Facility.
The Facility has been remediating soil and groundwater since 1979, when an inspection by PADEP noted that waste solvents including TCE had been released to the ground surface. Several soil removals have taken place to eliminate potential source areas of contamination, and an air stripper was installed in 1981 to remove TCE and PCE from groundwater. A soil vapor extraction (SVE) system was installed in 2007 to further remediate soils in the grassy area adjacent to the parking lot and garage. In addition, a recovery well was installed in 2009 downgradient of the facility to reduce the likelihood of groundwater contamination migrating off-site.
Primary contaminants at the facility include the chlorinated volatile organic compounds TCE and PCE. Soil and groundwater have been impacted by the contaminants. Significant exposures to contamination are unlikely due to the low levels of remaining contamination and the soil remediation and groundwater recovery efforts underway at the facility.
