Attachment 14.8 - utility water sampling data.pdf

This document is a utility water and steam sampling data report for Martinez facility covering four quarters in 2024-2025. The sampling schedule includes four quarterly collections: Quarter 1 (December 16, 2024), Quarter 2 (February 5, 2025), Quarter 3 (April 7, 2025), and Quarter 4 (July 7, 2025).

The report tracks five water quality parameters across two sample types designated as MON:19:1 and POU:19:1. Parameters measured include pH (ranging from 6.11 to 8.51), Conductivity (ranging from 6 to 495 microsiemens), Total Alkalinity (ranging from <5 to 75 mg/L), Total Hardness (ranging from <1 to 106 mg/L), and Bacteria levels (ranging from <1 to 37 CFU/mL). Reference standards are provided for each parameter, with acceptable ranges including pH 6.5-9.5, Conductivity <500, Total Alkalinity <400, Total Hardness <150, and Bacteria <500. All quarterly measurements remain within established reference standards, with Total Hardness values highlighted in yellow throughout the report, indicating these readings warrant particular attention despite compliance with limits.
