fi [7] CONCLUSIONS <br /> The results of the percolation tests indicate that there is a fast <br /> percolation of the shallow test boring on Parcel No. l at 5 min/in. <br /> However, the DR indicated a slower rate at 30 min/in, a relatively <br /> significant difference. <br /> f i <br /> I <br /> Therefore, it is recommended that the firm installing the septic <br /> system be aware of theotential di <br /> P fferences in soil structure, and <br /> to compensate for any soil discrepancies by the use of engineered <br /> backfill, or a larger leach field area. <br /> � I <br /> t <br /> As noted above, the water table is approximately 18 feet below the <br /> soil surface. Therefore, the groundwater level in this area is <br /> below the five foot minimum distance between the bottom of the <br /> leach field, and the highest anticipated depth to .groundwater, as ' <br /> of the date of this report. <br /> l <br /> Based upon the documented information from the percolation testing <br /> procedures and the highest depth to <br /> P g p groundwater, the proposed <br /> septic system should not produce additional nitrate contamination <br /> of the underlying groundwater. Since the subject property is not <br /> f subject to flooding, there should be no adverse impact to surface <br /> l waters. <br /> E <br /> I <br /> 4 <br /> 5 <br /> si Quality Jr�ontrol Inspection 4 <br /> s _ � <br />
