The percolation test has revealed that the onsite soils have a <br />moderately rapid percolation at shallow depths (<3.5 feet bgs). <br />2.2 Groundwater Analysis <br />2.2.1 Regional Groundwater <br />A discussion of regional groundwater, including depth to groundwater is included in Section 1.4.1. <br />No significant seasonal trends were evident from the sources consulted. <br />2.2.2 Potential Ground Water Contamination Issues <br />A discussion of issues related to potential groundwater contamination is included in Section 1.4.2. <br />2.2.3 Current and Future On-Site Ground Water Uses <br />The proposed Vineyard Chapel addition will be connected to the existing onsite domestic well.
