Draft Group RFI Reports

Data Gap Site Characterization Process Timeline: • Work Plan Approval -10 weeks after submittal

• Includes Public Meeting, input • Sampling and Data Evaluation, 1st Round – 20 weeks

• Field Sampling and Analysis • Data Evaluation • DQO Evaluation, ID Data Gaps

• Sampling and Data Evaluation, 2nd Round – 8-9 weeks • If Data Gaps are ID’d

• Goal – Identify if any chemicals found in vadose zone pose a threat to groundwater or if chemicals found in groundwater pose a threat to surface receptors through vapor migration • Soil, soil vapor, rock core, and groundwater data were evaluated

• Summary of evaluation to date:

• CMS for Groundwater Protection: • 1 CUA cluster – (1)

• VOCs • Collect Additional Groundwater Data:

• 5 CUA clusters – (1, 2, 3, 4, 6) • Conduct Vadose Zone Mass Flux to Groundwater Modeling:

• 2 CUA clusters • Hydrocarbons, VOCs – (1) • VOCs, Pthalates, Hydrocarbons – (4)

• Vadose Zone Evaluation will be re-visited after sample collection and

data evaluation

Groundwater Evaluation

•Goal – Evaluate Groundwater data gaps, extent, and impacts on plume scale

•Summary of evaluation to date: • Groundwater sampling to evaluate nature and extent of

groundwater impacts • 13 wells

• Plume stability will be evaluated after collection of additional groundwater data

•Groundwater evaluation will not be complete until

• Proposed groundwater sampling is complete • Vadose zone evaluations are complete
