Rajesh (Raj) SinghRajesh (Raj) Singh works at Kleinfelder in Exton, PA as a senior remediation engineer responsible for technical oversight on remediation projects throughout the firm. Raj works closely with technical staff and project managers to ensure that projects are conducted on time, within budget, and with the highest level of technical quality. His expertise includes feasibility study, treatability study, engineering design, drawings, specifications and construction management of remedial systems for groundwater, soils and sediments. He has significant experience and knowledge in the complexities associated with implementation of Solidification/Stabilization (S/S) technology in the field. He has been a Program Manager for a $35 million closure/remediation of three NPDES permitted impoundments using cement-based in-situ S/S. The impoundment sediments were impacted by petroleum hydrocarbons, tar, PCBs and metals (arsenic, hexavalent chromium, total chromium, lead, antimony and other metals). As part of the S/S closure project, he directed waste characterization, treatability testing, process scale-up, engineering plans and specifications, bidding assistance, and contractor bid evaluation. He also managed the construction oversight and obtained no further action approval from the NJDEP for three impoundments. In addition to this work with ITRC S/S Team, Raj is a frequent speaker and presenter on S/S technology at professional conferences. Raj earned a bachelor's degree in Civil Engineering from Allahabad University, India in 1983 and a master's degree in Environmental Engineering from Rutgers University, New Brunswick, New Jersey in 1986.
