Five of the r typically consists of twelve shallow tests achieved a satisfactory percolation rate.mower found to consist rmeable deep eofower permeability sand,and bounded by less permeable layers. The surface soils soils however several tests indicate a satisfactory percolation rates can be achieved in the shallow zone alone. Due to the heterogeneous sails encountered,the deep depth to ground water,clayey surface soils,we do not . believe that the rapid percolation-rate will cause abuildup of nitrates in ground water above 10-mg/L-N. This issue was discussed in more detail in the Addendum letter dated November 27,2000. Summar After a review of previous work conducted at the site and work completed during this effort,we have concluded that the new parcels are suitable for use with a septic system using leach lines and seepage pits. ading study, datedOctober 12, 2000,indicates a development density of 2.0- The soil suitability 1 nitrate lose a build up of nitrates in the ve safe acres or greater is suitable or the area.and will not cauground All neeeW°lots are drinking water levels established by the Environmental Protection Agency (EPA).
