Our scientists, engineers, and geologists are highly experienced in the design, operation, and management of remediation systems, including groundwater pump and treat, vacuum extraction, dual phase extraction, LNAPL recovery, and air sparging. One of our specialties is system evaluation and optimization based on site-specific technical and economic analyses, as well as analysis of existing remediation systems.
Statistical and Geostatistical Services | Monitoring System Optimization
We perform statistical analyses based on the nature, distribution, and regulatory needs of environmental data. We select and apply the most appropriate evaluation strategies and statistical procedures, including parametric or nonparametric analyses, comparison of multiple populations, and trend analysis for time series data. Using a variety of geostatistical analytical methodologies, including semivariogram modeling and kriging, we analyze the spatial structure or correlation of environmental data to provide guidance for spatial mapping, uncertainty assessment, and sample design.
Our monitoring optimization program (MOP) quantitatively evaluates the technical value of wells at a site, optimizing monitoring well networks for practical effectiveness. Led by Dr. Meng Ling, an expert in monitoring program optimization, the optimization consists of three phases: (1) a site and historical evaluation; (2) a statistical monitoring assessment; and (3) a summary evaluation. Significant and substantial benefits are achieved by monitoring well optimization, including cost savings, increased safety, and reduced site disruption. MOP optimizes both the number of monitoring wells and the frequency of sampling, so results are both immediate and long term. [Publications] [Statistical and Geostatistical Services Brochure]
