Transmissivity of the alluvial aquifer; <br />2. sto rativi ty; <br />3. depth of mottling; <br />4. depth of ground water; and <br />S. depth and width of alluvium <br />. A cuartcrly n~nnitorinq program will be established to determine any <br />changes to the alluvial aquifer that may occur. The Division c~~ill develop <br />a Iist of sampling parameters during the tinal rcvzew process. <br />/op <br />
