Due Date: 7/31/2026 Date Received: 7/30/2026 Responsible Person: Whitmyer, Nathan Statistical Exceedence?: Yes Branch: KZ - Kalamazoo District Office Review Notes: Several constituents exceeded Part 201 GRCC (Generic Residential Cleanup Criteria) in this sampling event: TDS at MW-48 and UD-1, dissolved arsenic at MW47d, and dissolved iron at MW-22s, MW-48, and UD-1. These are generally consistent with past events and historical concentrations. Vinyl chloride (3 ug/L) was also slightly above the GRCC at the UD-1 location in this event. In addition, there were several low-level VOC detections in groundwater from MW-49 in this event: benzene (4.6 ug/L), acetone (33.2 ug/L), and cis 1,2dichloroethene (1.7 ug/L). While The detections are likely anomalous/potential lab artifacts, VOCs will be analyzed from this well again in the 3rd quarter 2026 to confirm. Several constituents exceeded Part 201 GRCC (Generic Residential Cleanup Criteria) in this sampling event: TDS at MW-48 and UD-1, dissol ed arsenic at MW47d, and dissolved iron at MW-22s, MW-48, and D-1. These are generally consistent with past events and historical concen rations. Vinyl chloride (3 ug/L) was also slightly above the GRCC at the UD-1 location in this event. In addition, there were se eral low-level VOC detections in groundwater from MW-49 in this e ent: benzene (4.6 ug/L), acetone (33.2 ug/L), and cis 1,2dichl roethene (1.7 ug/L).

Dissolved iron at MW-22s (17.8 mg/L), MW-4b (2.3 mg/L), and UD-1 (16 mg/L); TDS at UD-1 (816 mg/L) and MW-48 (557 mg/L); and dissolved arsenic at MW-47d (0.0221 mg/L) exceeded the Part 201 GRCC (Generic Residential Cleanup Criteria) in this sampling event. Vinyl chloride (4.1 ug/L) was also slightly above the GRCC at the UD-1 location in this event. Statistically significant increases (SSIs) were observed at the UD-1 location (TDS, ammonia, and chloride). The exceedances are simi ar to past events. Dissolved iron at MW-22s (17.8 mg/L), MW-4 (2.3 mg/L), and UD-1 (16 mg/L); TDS at UD-1 (816 mg/L) and MW-48 (5 7 mg/L); and dissolved arsenic at MW-47d (0.0221 mg/L) exceeded he Part 201 GRCC (Generic Residential Cleanup Criteria) in this ampling event. Vinyl chloride (4.1 ug/L) was also slightly abo e the GRCC at the UD-1 location in this event.

Due Date: 7/31/2024 Date Received: 7/30/2024 Responsible Person: Whitmyer, Nathan Statistical Exceedence?: Yes Branch: KZ - Kalamazoo District Office Review Notes: Several constituents exceeded Part 201 GRCC (Generic Residential Cleanup Criteria) in this sampling event: dissolved iron at MW-22s; TDS and dissolved iron at UD-1; dissolved arsenic at MW-47d; and TDS at MW-48. These are generally consistent with past events and historical concentrations. Vinyl chloride (3.7 ug/L) was also slightly above the respective GRCC at the UD-1 location in this event. These are generally consistent with past events and historical concentrations. In addition, several VOCs were detected at MW-49 (benzene 2.7 ug/L, vinyl chloride 1.3 ug/L, and cis 1,2-dichloroethene 3.3 ug/L). VOCs have never been detected in this well before and these concentrations are below any current groundwater criteria. The detections are likely anomalous, and VOCs will be analyzed from this well again in the 3rd quarter 2024 to confirm. Several constituents exceeded Part 201 GRCC (Generic Residential Cleanup Criteria) in this sampling event: dissolved iron at MW-22s; DS and dissolved iron at UD-1; dissolved arsenic at MW-47d; a d TDS at MW-48. These are generally consistent with past events and h storical concentrations. Vinyl chloride (3.7 ug/L) was also sl ghtly above the respective GRCC at the UD-1 location in this eve t. These are generally consistent with past events and historic l concentrations. In addition, several VOCs were detected at MW- 9 (benzene 2.7 ug/L, vinyl chloride 1.3 ug/L, and cis 1,2-dichlo oethene 3.3 ug/L). VOCs have never been detected in this well befo e and these concentrations are below any current groundwater crite ia. The detections are likely anomalous, and VOCs will be ana yzed from this well again in the 3rd quarter 2024 to confirm.

The exceedances are similar to past events. Statistically significant increases (SSIs) were observed at MW-22s (ammonia, TDS, dissolved barium, and chloride); MW-48 (TDS and dissol ed barium); the UD-1 location (TDS, ammonia, dissolved arsenic, chl ride, and dissolved barium); and at MW-47d (dissolved arsenic).
