Project Navigator, Ltd. (PNL) has been facilitating outreach to the Hinkley Community focusing recently on the findings from USGS’s ongoing Cr6 Background Study. With the expectation of a final report by 2020, Community members have been learning of the multiple causes of Cr6 concentrations in groundwater.

Hinkley residents gathered in April, 2019 at the Hinkley Community Center to listen to presentations by PNL’s Dr. Raudel Sanchez, and USGS’s Dr. John Izbicki covering, respectively, the overall status of PG&E’s Cr6 groundwater remediation program, and the Background Study. Representatives from the Lahontan Regional Water Quality Control Board and the Pacific Gas and Electric (PG&E) also made comments.

Project Navigator, Ltd. welcomes new hire, Matt Jackson, to its Houston office

PNL is pleased to announce a key addition to our construction management capacity with the addition of Mr. Matt Jackson to the team. Matt is joining PNL in Houston, TX and brings over 28 years of experience in environmental and civil construction. Most recently, Matt served as a Program Manager for RECON, where he managed a group of Project Managers and was responsible for providing support in oversight, cost estimate development, proposal preparation, cost tracking, and scheduling of various large-scale, multi-faceted projects. His particular focus was on solidification/stabilization, demolition, impermeable clay cap construction and other large “dirt work” projects. This included a $185MM portfolio of projects for a major oil company where refineries in the US, Puerto Rico and Canada were decommissioned, demolished and remediated so the properties could be sold. He also lead the efforts to develop RECON’s international business in Asia, Mexico, Puerto Rico, and Central America markets.

Matt’s charge, supported by client demands for an ever present focus on remedy quality, project execution safety and cost-effectiveness, is to add value to our Clients’ projects through our construction management group, and to grow PNL’s EPC practice. PNL’s practice has already managed remedy implementation at CERCLA Sites nationwide, with project values up to $50 million, and included remedy elements from landfill construction to stack demolition to sediment capping. Matt will report to Marc Ferries, PE, Houston Office Manager, and can be reached at (832) 960-4987.
