Richard W. Blackmer, PE
Senior Principal Engineer

Mr. Blackmer has over 30 years of professional experience managing and conducting technical studies in remediation engineering at contaminated sites and at brownfield redevelopment projects.  Mr. Blackmer is an expert in conceptual site model development using geologic, hydrogeologic, geophysical, geochemical, and biological methodologies. He is also an expert on in-situ and ex-situ physical, chemical, thermal, and biological remediation technologies. Mr. Blackmer applies these combined skills to develop technically sound and cost-effective remedial strategies to remediate environmental contamination. Mr. Blackmer has performed feasibility analysis, design, and implementation of remediation approaches for soil, soil vapor, and groundwater impacted with a variety of chemicals of concern, including chlorinated solvents, petroleum hydrocarbons, metals, perchlorate, NDMA, 1,4-dioxane, and several other compounds included on emergent chemicals lists.  Mr. Blackmer has practical experience in the enhancement of traditional remediation approaches through innovative methods of distribution of remedial amendments using environmental fracturing, hydraulic fracturing, and multi-screened horizontal wells. Mr. Blackmer is also an expert regarding the operation, maintenance, and performance optimization of remediation systems.  He has designed and implemented pilot testing programs for state-of-the-art groundwater treatment devices, including MTBE and 1,4-dioxane treatment using a modified In-Well Air Stripping methodology, MTBE remediation using a super critical fluid extraction with membrane structures and liquid carbon dioxide and perchlorate and nitrate treatment using a biological approach with an anoxic fluidized bed carbon canister.    With his broad base of experience, Mr. Blackmer possesses the unique ability to troubleshoot existing remediation systems that are either not performing up to expectations or not accomplishing the remedial objectives, recommend modifications to the remediation system design or operational approach, and implement recommendations in a timely and cost-effective manner.

Klaus P. Rohwer, PG, LG, LHg
Senior Principal Geologist

Mr. Rohwer has over 30 years of experience as an expert in planning, managing, and implementing projects to characterize and remediate environmental contamination in many geologic and hydrogeologic settings.  As a Client advocate, Mr. Rohwer has proactively conferred and negotiated with local, State, and Federal regulators to establish concise  project strategies based on project-specific objectives, including: the assessment of media and chemicals of concern; development of conceptual site models; identification of sensitive receptors and exposure pathways; quantification of human health and ecological risks; evaluation of corrective measures; and the selection and implementation of corrective measures.  Mr. Rohwer has exercised these expertise to characterize and remediate chlorinated solvents, petroleum hydrocarbons, metals, hydrazine, and emergent chemicals in alluvial, fluvial, lacustrine, coastal, glacial, and bedrock systems.  Mr. Rohwer also provides expert-level technical consultation to support realized or potential legal action, including: discovery document review, analysis, and cataloging; technical position development, interpretation and opinion; exhibit preparation; third party review; and management and technical support to multi-party mitigation and arbitration.  He works both as a technical consultant as well as an outsourced project manager.

Eric H. Wiebe, PG, CEG
Senior Principal Hydrogeologist

Mr. Wiebe’s primary focus for our Clients is in strategic planning and expert-level technical review and analysis on water resource development, protection, and environmental cleanup to closure programs throughout  the U.S. and four other continents.  Mr. Wiebe is a second-generation hydrogeologist in California, and has 37 years of experience in the applications of hydrogeology, geochemistry, engineering geology, and environmental remediation engineering.  Mr. Wiebe provides technical direction on water resource and environmental projects, both nationally and internationally, including the development and protection of new groundwater resources, design-support and analysis of municipal and hazardous waste landfills, remediation of industrial, commercial, and former military manufacturing  facilities impacted by anthropomorphic organic chemicals, petroleum hydrocarbons, explosives and accelerants, and metals in both soil and groundwater, and provides hydrogeologic and geochemical expertise to several water supply agencies.   He has utilized both standard and innovated methods for groundwater assessment, extraction, and treatment.  Mr. Wiebe has worked both as a technical consultant to Clients as well as an outsourced project manager for his Clients, routinely provides expertise for environmental engineering Red Team design reviews for projects throughout the globe, and has developed numerous life-cycle cost estimates for large multi-project environmental portfolios, Superfund Sites, and water-resource protection projects.

Christopher B. Stoker
Principal Risk Assessor

With over 28 years of experience, Mr. Stoker is responsible for designing, developing, and overseeing all aspects of the company’s human and ecological risk assessments.  This includes indoor air assessment, receptor and exposure scenario development, toxicity assessment and selection of constituents of concern, contaminant fate and transport analysis (vapor intrusion modeling, air dispersion modeling, groundwater modeling, cross media transport), data evaluation and management, statistical analysis, and risk characterization.  He is the technical lead during negotiations with regulatory agencies over the development of vapor intrusion assessment programs, multi-media cleanup goals, and potential land use covenant conditions.  Mr. Stoker works closely with our Clients to identify project-specific goals and strategies, optimize the Client’s position with regulatory agencies, and minimize future liabilities.  He frequently manages the development of site remedial strategies incorporating the evaluation of remedial alternatives and technologies designed to enhance  site closure.  As a senior Project Manager, Mr. Stoker is the primary point of contact for day-to-day communication with the Client and regulatory agencies (DTSC-HERD, OEHHA, RWQCB, U.S. EPA, etc.).  The commercial industries that Mr. Stoker has served include aerospace, chemical, utility, municipal, hazardous waste incineration, petrochemical, mining, insurance, legal, and property development/management.  Mr. Stoker has provided management on U.S. DOD and commercial contracts as well as providing technical lead on numerous U.S. DOE, Federal, State and local agency projects.
