220 JACKSONVILLE RD

In 1972-1973, when the four lagoons that once stored wastewater from the site were closed, the remaining waste sludge was removed by a potentially responsible party to an off-site disposal facility. The lagoons were backfilled with clean soil. In September of 1991, EPA issued a Record of Decision (ROD), choosing a remedy for the soil and source control. The remedy included soil vapor extraction (SVE) and a low-permeability cap. The design of the remedy was completed in 1994. The SVE system operated from March 1994 until soil cleanup levels were met in October 1995. Cap construction was completed in April 1994. In December of 1990, the ROD for the groundwater (OU2) and contaminated drinking water wells (OU3) was issued. The groundwater remedy included extracting groundwater, treating it through air stripper towers with vapor phase carbon adsorption, and discharging it via storm sewer to a nearby creek. The cleanup remedy also included the use of air stripper towers with vapor phase carbon adsorption at existing contaminated drinking water wells. In September 2007, EPA issued an Explanation of Significant Differences (ESD) that modifies the approach to groundwater remediation at the Site, eliminating the institutional control component in the ROD for OU2 and OU3 that ensured continuous public water supply operation and treatment by the Hatboro Borough Water Authority. The ESD also requires institutional controls in connection with the on-site treatment system as well as contaminated groundwater attributable to the Site. The third five-year review was completed in September 2008, and identified three items requiring follow-up: operation and maintenance (O&M), potential vapor intrusion, system optimization. PADEP is the lead on O&M and system optimization. Data from this effort will be relayed to the Hatbroo Borough and documented in a upcoming five-year review addition.
