Title: Site Characterization, OSTP RCRA Facility Investigation
Client: Pantex Plant, Mason & Hanger Corporation
Amarillo, Texas
This project was a RCRA facility investigation to determine the vertical and horizontal extent of metals contamination below the
concrete sludge beds at the DOE Pantex Plant Old Sewage Treatment Plant (OSTP). Historically, the OSTP treated wastewater streams containing sanitary sewage and industrial
effluent from the Pantex Ordnance Plant, Amarillo Air Force Base, and the Pantex Plant. In addition, the sludge beds had received the by-product sludge residue removed from other treatment
plant units. Work performed included evaluating existing data from previous site investigations; preparing project work plans, including the health and safety plan (HASP), sampling and
analysis plan (SAP), and quality assurance project plan (QAPjP); taking core samples through the concrete sludge beds to obtain soil samples to a depth of 30 feet; installing two
groundwater monitor wells and collecting groundwater samples; analyzing the samples for heavy metals, particularly lead and mercury; preparing plume maps; validating the data; and
preparing the Final Implementation Report. Based upon results of this investigation, as well as ETAS Corporation's evaluation of data collected from previous investigations, the OSTP
was recommended for closure in accordance with the Texas Natural Resource Conservation Commission (TNRCC) Risk Reduction Rules (RRR).
