Wells shall comply with <br /> requirements of the Department of Water Resources. The following constitutes the groundwater <br /> monitoring program: <br /> Constituents Units Tyne of Sample <br /> Elevation' feet (MSL) ---- <br /> Specific Conductivity µmhos/cm Grab <br /> Nitrates (as N) mg N/1 Grab <br /> Total coliform organisms MPN/100 ml Grab <br /> ' The elevation shall be used to calculate the gradient and direction of groundwater flow,which shall <br /> be reported with the monitoring report. <br /> r <br /> REPORTING <br /> Monitoring results shall be submitted to the Regional Board by the 20th day of the month <br /> following sample collection.
