June 11,2003 <br /> Job Number:LG03-137 <br /> Page 11 <br /> The nitrate loading study indicated that the site is sensitive to a buildup of nitrates in the ground <br /> water due-to the high nitrate level in the well water, the small parcel size, and the low estimated <br /> recharge from rain water of the aquifer. If the customer use increases above 5 per day over the <br /> long term,.a potential build up of nitrates may occur within the shallow ground water zone. _ <br /> We believe'the presence of dark colored clayey soils will be beneficial condition-and we have <br /> assumed they will achieve a 35%denitrification rate.,Another potentially beneficial factor is the <br /> land use has changed from a retail pottery business to a relatively lower use of the.RV-sales <br /> facility.'This assumes that more customers.visit a pottery store than an RV,sales facility. <br /> Based on the results of this study, our office believes the-proposed project is suitable for use with <br /> the existing septic system provided,the following recommendations are followed: . <br /> 1 For large atherin s ors ecial events beyond the use assumptions made in ths <br /> report, we recommend the use of portable toilets. <br /> 2) Replace the toilet with a-low flow system to satisfy the assumptions of 1.7 gallons <br /> per flush described in this report. <br /> 3) Drink bottled water in place of the well water. We would recommendthat the <br /> water-quality of the well be,periodically monitored to establish abase line for the <br /> nitrate level within the aquifer: At some pointin the future if the well water <br /> quality does not improve, a replacement well should be installed: <br /> 4) , We recommend that the condition of the existing septic tank be checked by a <br /> . <br /> qualified septic system service company. Since the septic system is 23 years old, <br /> it should be;checked to verify the system is,in a satisfactory condition prior to <br /> opening for business. <br /> 8.0 LIMITATIONS . <br /> The conclusions of this report are based on the information provided regarding the existing and <br /> proposed development, the use of the subject property,`and the site conditions as they existed at <br /> the time we excavated our test holes and performed the percolation tests. It was assumed that the <br /> test holes and percolation test results are representative of the subsurface conditions.in the <br /> general area. <br /> p ti <br />
