Sunrise Trucking—Nitrate Loading Section Page 11 of 16 <br /> Our Project Number: NA157003G <br /> October 23, 2015 <br /> 2.1 Chemical and Physical Properties of Soil <br /> 2.1.1 Chemical and Physical Soil Properties <br /> For a discussion of on-site soil properties, refer to Section 1.5. <br /> 2.1.2 Mass Transport Soil Properties <br /> The percolation test has revealed that the soils from 0.75 to 3.50 feet are permeable and will allow <br /> for moderate to rapid infiltration of water. The longer the effluent remains near the surface, the <br /> more treatment is enhanced due to natural processes within the soil. If the permeable soils exist <br /> to the depth of the groundwater table, it is possible that surface contaminants may be transported <br /> fairly rapidly. <br /> 2.2 Groundwater Analysis <br /> 2.2.1 Regional Groundwater <br /> A discussion of regional groundwater, including depth to groundwater and flow gradient is <br /> included in Section 1.4.1. No significant seasonal trends were evident from the maps 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 /> There is currently one well on the site, used to supply drinking water, as noted in Section 1.4.3. <br /> 2.3 Sources and Impact of Nitrate to Groundwater <br /> ' 2.3.1 Current Off-Site Sources of Nitrate <br /> I Septic systems, agriculture, and dairies in the area may be the most significant sources of nitrate <br /> in groundwater. Septic tank use in the vicinity is discussed in Section 1.3.4. <br /> ©2015 Neil O.Anderson&Associates,Inc. <br /> A Terracon Company <br />
