Application of Environmental Sequence Stratigraphy and facies models benefit groundwater remediation projects by improving the ability to:1、 Interpret lateral continuity between borehole data and correlate site data in three dimensions;2、 Identify groundwater flow paths and preferential contaminant migration pathways;3、 Map and predict contaminant mass transport (high permeability) and matrix diffusion- related storage (low permeability) zones;4、 Identify data gaps and assess the need and cost benefit of high resolution site characterization;5、 Determine appropriate locations and screen intervals for monitoring and remediation wells, and;6、Improve efficiency of remediating and monitoring of contaminated groundwater.
