NotesGaps in sampling events are a result of either dry wells or inaccessible wells. In addition, the Group I Parcel wells are sampled on a semi-annual basis as of July 2016, with the exception of wells near the Group II Parcel. Parcel S well samples pending-- = Analysis not performed< = Concentration is less than reported limitU = Concentration was not detected above the reported limitJ = Indicates an estimated value.J+ = Indicates a value estimated high Legend for Exceedance:R = Result rejected during validationNS = No Standard Blue Text Excceds an SL(N) = Normalized sample locations created from combining parent and field duplicate samples following EPA protocol Shaded Exceeds Groundwater SLLab comments and definitions can be found in associated laboratory and validation reports.

SLs shown on this table were presented in the Multi-Site Risk Assessment Framework Addendum Revision 5 (Exponent, July 2016). Groundwater SL shown on this table are 10-6 risk value or the MCLs. Risk-based groundwater SLs, tapwater SLs, and VI SLs are non-enforceable SLs.

NotesGaps in sampling events are a result of either dry wells or inaccessible wells. In addition, the Group I Parcel wells are sampled on a semi-annual basis as of July 2016, with the exception of wells near the Group II Parcel. Parcel S well samples pending-- = Analysis not performed< = Concentration is less than reported limitU = Concentration was not detected above the reported limitJ = Indicates an estimated value.J+ = Indicates a value estimated high Legend for Exceedance:R = Result rejected during validationNS = No Standard Blue Text Excceds an SL(N) = Normalized sample locations created from combining parent and field duplicate samples following EPA protocol Shaded Exceeds Groundwater SLLab comments and definitions can be found in associated laboratory and validation reports.

SLs shown on this table were presented in the Multi-Site Risk Assessment Framework Addendum Revision 5 (Exponent, July 2016). Groundwater SL shown on this table are 10-6 risk value or the MCLs. Risk-based groundwater SLs, tapwater SLs, and VI SLs are non-enforceable SLs.
