Characterization & Planning

Characterization & Planning

LATA is skilled in the conduct of site-specific building, soil and groundwater characterization to determine the nature and extent of contamination, and to support remediation and waste management decision-making. Our services include fate and transport modeling, human health and ecological risk assessment, remedial alternatives evaluation and feasibility studies, conceptual and detailed remedial design and implementation planning, and post-remedial action cleanup confirmation.

LATA designs each characterization approach in accordance with requirements relevant to the regulatory/stakeholder jurisdictions including RI/FS processes under CERCLA and RFI/CMS processes under RCRA. LATA identifies data needs and data quality objectives (DQOs) sufficient to support key decisions, while avoiding the kind of over-sampling that can lead to excessive cost without attendant benefit.

Our characterization and planning expertise includes designing statistically appropriate investigation programs, developing required plans and procedures, collecting samples that are representative of the media of interest, and use of field screening tools to focus sampling. We have extensive experience with data collection at all quality levels, from the use of handheld field survey instruments to record immediate data readings to collecting samples for field, laboratory, or fixed-based laboratory analysis. We choose the right techniques to meet the requirements, while ensuring that only the data required to support our clients ‘decision-making are obtained.

LATA can link characterization output to GIS and 3-dimensional data visualization tools that summarize and integrate spatially oriented site characterization data to support site conceptual model understanding and clean-up decisions. Our planning includes projection of waste volumes, least-cost disposal pathways and the identification of waste minimization techniques to control cost.
