WASTEWATER TREATMENT FACILITY SAN JOAQUIN COUNTY Sampling and Constituents Units Soil Profile Revortiniz Fre uenc Nitrate (as N) mg/kg Standard' Annually, Total Kjeldahl Nitrogen mg/kg Standard' Annually, ' Samples shall be collected at 0.5 feet, 3 feet, and 6 feet in depth.. ' Samples shall be collected in September. GROUNDWATER MONITORING Prior to completion and/or sampling of any groundwater monitoring wells, the Discharger shall submit plans and specifications to the Board for review and approval. Once installed, all new wells shall be added to the MRP and shall be sampled and analyzed according to the schedule below. Prior to sampling or purging, equilibrated groundwater elevations shall be measured to the nearest 0.01 foot. Depth to groundwater measurements shall be collected from all wells on the same day. The wells shall be purged at least thtee well volumes until pH and electrical conductivity have stabilized. Sample collection shall follow standard EPA analytical method protocols. Groundwater monitoring shall include, at a minimum, the following: Sampling Reporting Constituent Units Type of Sample Frequency Frequencx Depth to Groundwater 0.01 ft Measurement Quarterly Quarterly Groundwater Elevation 0.01 ft Calculated Quarterly Quarterly Gradient ft/ft Calculated Quarterly Quarterly Gradient Direction Degrees Calculated Quarterly Quarterly pH S.U.

Z Annual samples shall be collected in the first quarter(January-March)sampling event. REPORTING In reporting monitoring data, the Discharger shall arrange the data in tabular form so that the date, sample type (e.g., effluent, groundwater, etc.), and reported analytical result for each sample are readily discernible. The data shall be summarized in such a manner to clearly illustrate compliance with waste discharge requirements and spatial or temporal trends, as applicable. The results of any monitoring done more frequently than required by the Monitoring and Reporting Program, including wastewater data collected for industrial wastewater discharge permits, shall be reported in the next scheduled monitoring
