We specialize in practical, cost-effective solutions to complex environmental problems.
PNG conducts investigation and remediation of hazardous substances and petroleum releases throughout the Pacific Northwest with sites involving impacted soil, sediment, groundwater, and vapor. Over three decades of professional experience provides in-house expertise with contaminants including VOCs, PAHs, PCBs, Metals, Pesticides & Herbicides, Asbestos, and mixtures of a variety of LNAPLs and DNAPLs. Our successful application of remedial technologies range from the typical hydrocarbon techniques to multiple in-situ destruction options, enhanced NAPL recovery, bioremediation, barrier walls, and excavation/dredging. PNG projects are well received by the Oregon and Washington regulatory agencies, as we strive to focus the investigative efforts to only the essential physical, chemical, and biological data necessary to quickly select and implement a remedy. Our approach is always tailored to our Client's goals, whether applying a routine and proven technology, pilot testing and implementing cutting-edge remedies, or performing, testing and evaluating models necessary to develop risk-based closures.
As small business owners, we understand and appreciate the fiscal and logistical challenges created from often unexpected environmental problems. Our small size and concentration on environmental investigation and cleanup projects allows PNG to be highly cost-competitive. For larger projects, we routinely team with other small firms to increase our capabilities and supplement our expertise. Through years of successful and efficient project completion, PNG has built a reputation for efficiency, resulting in a strong working relationship with insurance companies. A majority of our cleanup work for industry is now funded by insurers.
Site assessment and remedial investigations
Risk assessment and risk-based analysis
Feasibility Studies and EE/CAs
Field scale pilot testing
Remedial design and implementation
Remedial system performance evaluations
TSCA analysis and cleanup
Property transfer due diligence
Environmental cost analysis/audits
Contamination source evaluation and release history
Cost recovery, allocation and mediation support
Expert witness testimony and litigation support
A founding goal of limiting our staff size to a core of experienced environmental professionals has allowed PNG to build a solid practice in the expert witness/litigation support arena. Starting with expert evaluation and oversight of cleanup activities in Oregon and Southern Washington, our practice has grown to include sites throughout the western U.S. Typical tasks in these litigation projects include:
Review of incurred and claimed cleanup costs
Independent development of past and future site investigation and cleanup costs (based on PNG's hands-on experience)
Regulatory analyses related to agency mandates
Defining the extent of a cleanup through application of applicable standards and development of risk-based site-specific standards to affected media
Research of historic site practices including extensive historical aerial photography analyses
Environmental forensics such as source identification, timing of releases, and determining the fate of chemicals
Evaluation of NRDA damages
Development of allocation and contribution positions
For these environmental projects, PNG routinely manages technical discovery, performs expert evaluation of other consultant investigation and cleanup efforts, and develops independent remediation scenarios and costs based on applicable federal and state standards and guidance. We often are able to apply practical, risk-based analyses to existing site data and develop alternative remedial schemes. PNG has extensive experience with preparation of deposition outlines, declarations and interrogatories, mediation materials, and trial exhibits. The foundation for our testimony in mediation and trial is built on the active investigation and cleanup work our staff has been conducting for over 25 years.
