MONITORING AND REPORTING -3- S. M. S. BRINERS, INC. SURFACE IMPOUNDMENT CLOSURE SAN JOAQUIN COUNTY Protection Standard. Existing water quality monitoring stations and data can be proposed for incorporation in the revised monitoring system and program. The proposal shall include: 1 . Proposed conceptual design and location of water quality monitoring points including those at the point of compliance (Section 2550.7) ; 2. Proposed monitoring parameters, constituents of concern, and their monitoring frequencies (Section 2550.7 and Section 2550.8) ; 3. Proposed concentration limits and/or methods for establishing concentration limits (Sectin 2550.4) ; and, 4. Proposed statistical methods for determining statistically significant evidence for a release from surface impoundments. Ground Water Monitoring The existing ground water monitoring system consists of monitoring wells and production wells used for monitoring. Monitoring wells are identified as MW-1, MW-2, MW-3A, MW-3B, MW-4A, MW-4B. Production wells are identified as A, B, C, P1, P2, P3, P4, P5 and P6. Wells MW-1, MW-2, MW-3A and MW-4A monitor shallow zones of the Upper Laguna Formation, while MW-3B and MW-4B monitor deeper zones of the Upper Laguna Formation. The Discharger shall continue to monitor these wells for the constituents and parameters specified below at the specified frequency. Report in Reporting Parameter/Constituent Units of Freauencv Temperature (field) °C Quarterly Specific Conductance (field) µmhos/cm Quarterly pH (field) pH units Quarterly Total Dissolved Solids mg/l Quarterly Chloride mg/l Quarterly Field and laboratory tests shall be reported in the quarterly monitoring reports. Total Dissolved Solids results shall be submitted on a site contour map. All parameters shall be graphed so as to show historical trends at each well .
