NOTES: 1. HGU = HY DROGEOLOGIC U NIT. 2. TCA+ = 1,1,1-TCA AND BREAKDOWN PRODU CTS (1,1-DCE AND 1,1-DCA). 3. THIS FIGU RE DEPICTS THE TCA+ GROU NDWATER QU ALITY DATA WITHIN HGU s, AS DEFINED IN THE JANU ARY 2018 CONCEPTU AL SITE M ODEL (CSM ) REPORT.

4. HGU s DIP TO THE NORTHWEST AND THEREFORE HGU s 1, 2, 3, AND 4 ARE NOT U NIFORM LY PRESENT BENEATH THE ENTIRE SITE AS THEY SU BCROP (i.e., INTERSECT THE BEDROCK SU RFACE) FROM EAST TO WEST ACROSS THE SITE. HGU SU BCROP BOU NDARIES FOR HGU s 1, 2, 3, AND 4 ARE SHOWN AND THE RESPECTIV E HGU s ARE NOT PRESENT EAST OF THESE LINES.

5. ALL CONCENTRATIONS ARE IN PARTS PER BILLION (PPB). 6. THE TOTAL SU M OF TCA+ DETECTIONS PRESENT IN GROU NDWATER ARE INCLU DED IN THE ISOCONCENTRATION CONTOU RS.

7. THE DATA BOXES SHOW ALL GROU NDWATER CONTAM INANT DETECTIONS FOR TCA+. TCA+ SAM PLE RESU LTS AT AND BELOW THE NEW JERSEY DEPARTM ENT OF ENV IRONM ENTAL PROTECTION (NJDEP) GROU ND WATER QU ALITY STANDARDS (GWQS) ARE SHOWN IN PARENTHESES. TCA+ SAM PLE RESU LTS GREATER THAN THE NJDEP GWQS ARE SHOWN WITHOU T THE PARENTHESES. WELLS WITH SAM PLES THAT HAV E NO DETECTIONS OF TCA+ ARE M ARKED “ND”.

8. THE DATA SU M M ARIZ ED ON THIS FIGU RE INCLU DE THE SITE-WIDE SEM I-ANNU AL SAM PLING EV ENT CONDU CTED IN 3Q 2017 AND INTERIM REM EDIAL M EASU RES (IRM ) PERFORM ANCE M ONITORING DATA.

9. DU RING THE 3Q 2017 SAM PLING EV ENT, ALL WELLS WERE SAM PLED V IA PASSIV E DIFFU SION BAG (PDB) FOR THE V OLATILE ORGANIC COM POU NDS (V OCs) BETWEEN OCTOBER 17, 2017 AND OCTOBER 31, 2017. DU RING IRM PERFORM ANCE M ONITORING EV ENTS WELLS WERE SAM PLED V IA LOW-FLOW FOR V OCs BETWEEN AU GU ST 1, 2017 AND NOV EM BER 9, 2017. WESTBAY PORT SAM PLING (DW-65, DW-69, DW-70, AND DW-72) FOR V OCs WAS CONDU CTED BETWEEN SEPTEM BER 27, 2017 AND OCTOBER 4, 2017.

10. THE M OST RECENT HISTORICAL DATA WERE U SED FOR WELLS THAT WERE NOT SAM PLED DU RING THE CU RRENT REPORTING PERIOD TO INTERPOLATE TCA+ CONTOU RS. THESE DATA ARE SHOWN IN GRAY DATA BOXES.

11. IN SOM E CASES, ADJACENT WELLS SCREENED AT DIFFERENT DEPTH INTERV ALS HAV E CONCENTRATIONS THAT DIFFER BY M ORE THAN AN ORDER OF M AGNITU DE. IN THESE CASES, THE WELL WITH THE HIGHEST CONCENTRATION WAS U SED FOR CONTOU RING PU RPOSES.

12. TOTAL TCA+ ISOCONCENTRATION CONTOU RS ARE SHOWN DASHED WHERE INFERRED. 13. GROU NDWATER QU ALITY DATA OF OFF-SITE WELLS ON THE BRIAD PROPERTY (NORTH OF ROU TE 3), COLLECTED BETWEEN JANU ARY AND DECEM BER 2016, WERE U SED FOR CONTOU RING THE EXTENT OF TOTAL TCA+ IN THIS AREA. REFER TO RANSOM RIR APRIL 2017.

14. DELU XE WELLS LOCATED ON-SITE AND OFF-SITE WERE LAST SAM PLED BY ROCHE IN 2015 OR 2016.

15. SELECT WELLS SAM PLED DU RING THE 3Q 2017 SAM PLING EV ENT AND THE IRM PERFORM ANCE M ONITORING EV ENTS WERE DECOM M ISSIONED SU BSEQU ENT TO SAM PLING.
