Deficient Reporting |
Water quality samples were collected in early October and submitted to DWR's contract analytical laboratory. However, an unresolvable contract issue developed between DWR and the laboratory. As a result, the October samples were not analyzed. No samples were collected in November 2025 and December 2025 due to the plant being offline for plant maintenance. Water quality samples were collected on 1/26/2026 and were submitted to DWR's new analytical laboratory. |
