Finnemore andsche paper, they discuss three options to consider as potential methods ucing the mounhenomenon. The first is increasing the size of the disposal field. upon the averaly flow calculations found in Table 8, Page 17, it is anticipated the al area is sufficsize to accommodate the projected flow volumes after Phase 1 build- he disposal areased on mathematical computations for sizing found in the S.J.C. ge Standards anparameters. The second method is elongating the shape of the area covered by the disposal field. As noted on the Site Plans, the disposal area is a rectangular 1.6 LxW at 417 ft L x 249 ft W. Thirdly, operating the field intermittently should decrease the mounding effect. Effluent can be pumped by two or more pumps that could alternate between the two or more sub-disposal filter beds, thus creating intermittent dosing of each area. If it is determined at some point in the future, that mounding effects are preventing proper effluent treatment and disposal, the area designated as the 100% replacement/reserve areas may have to be activated. Activation of the 100%reserve area may occur prior to attaining the projected gpd I flow volumes referenced on Page 17 after the phased completion and full occupancy. 3.3 Domestic Well Groundwater Chemistry SSS§4.3,4.4,4.5 Extensive chemistry was conducted on water from the on-site domestic well. The on-site irrigation well approximately 30 ft north of the domestic well. This well was not tested since it almost assuredly does not have a grout seal. Consequently, analysis of water from this irrigation well would not be truly representative of water drawn from specific aquifers. Sampling of the domestic well was done from a hose bibb on the north side of the well. The pump was allowed to run 15 minutes and cycle lOx before the sample was taken. The bacteriological sample was taken first. Before sampling, the hose bibb was "flamed"to sterilize the exterior. Sampling for the other constituents was done with specific containers referenced on the Chain of Custody form. All of the samples were placed in a cooled ice chest and immediately transported to FGL Laboratories in Stockton, California. The following Table summarizes the analytical results of the major constituents tested: Page -13- Chesney Consulting
