Record elevation <br />of the water Zeve1 in the well at time of sampling. <br />b. Sample water for complete chemical analysis semi- <br />annually. <br />Z. Alluvial Aquifers *** <br />a. Measure field water quality parameters monthly (pH, <br />conductivity, and temperature). Record elevation <br />• of the water Zeve1 in the well at time of sam~7ling. <br />b. Sample water for complete chemical analysis quarterly. <br />**" Aquifers monitored and monitoring Zocations will be dealt with on an <br />individual basis.
