Permeability <br /> is slow in Archerdale soil.Archerdale soil typically has the same chemical properties between 0-60 <br /> inches bsg. The pH level ranges between 6.6 - 7.3 units with a salinity of less than 2.0. 1 <br /> 7.2. MASS TRANSPORT PROPERTIES OF UNDERLYING SITE SOILS <br /> This deep well-drained rich soil has a high available water-holding capacity.The natural fertility of <br /> this soil lends it very well to sustainable farming practices. Permeability is slow, available water <br /> capacity is high and the shrink-swell potential is high. Septic leech fields should have an increased <br /> absorption field to overcome the slow permeability. <br /> I` <br /> 8.0. GROUND WATER ANALYSIS <br /> The previous property water supply well was not sampled for nitrate analysis. The well is located <br /> on the adjacent parcel and access was not granted by the property owner for sampling. The newly <br /> installed water supply well on the property was not sampled. <br /> 8.1. DESCRIPTION OF LOCAL GROUND WATER <br /> E <br /> The San Joaquin County Flood Control and Water Conservation Districts Lines o.� qual Depth to <br /> Water Spring 1999 indicates the depth to round water is 90 feet or less. Ground water is <br /> Ground p g p g <br /> Z ]f appears to flow to the southeast in the direction of the Calaveras River. AGE performed a ground <br /> f water query on the California Department of Water Resources (CDWR) Internet site, <br /> http://well.water.ca.gov_. Based on the CDWR the current depth to ground water surrounding the <br /> subject property was 100 feet to 120 feet bsg (Appendix D). <br /> 1 Based upon a record review conducted at EHD by an AGE representative depth to water was <br /> indicated on well permits for the surrounding area to be between 156-feet and 280-feet bsg.The well <br /> on the adjacent property was to a total depth of 156 feet. <br /> Advanced GeoEnvironmental,Inc. <br /> 1 <br />
