The <br /> project involves constructing twenty-three new septic systems <br /> on the approximate 27-acre property. In addition, the <br /> residences will be connected to the city water system. ' <br /> Therefore, with groundwater at a depth of approximately 80 <br /> feet, in our opinion the likelihood of a significant change <br /> in the nitrate level of the groundwater beneath the site <br /> because of the additional systems is remote. If additional, \_ <br /> more-concentrated development using domestic wells is planned <br /> in the area, we suggest that consideration be given to <br /> completing a nitrate loading study. <br /> This completes our Scope o1 worx at thl.2 line. Baa a on the above <br /> information, it is our opinion that the proposed subdivision is <br /> suitable for septic system use. The septic systems should be <br /> located and constructed following County requirements and the <br /> recommendations presented in thio report. Continuous monitoring of <br /> the septic systems should be maintained throughout the duration of <br /> their use. Once this report is reviewed by Environmental Health <br /> services, we would be pleased to furnish a proposal for providing <br /> whatever additional information they may require for their <br /> evaluation. <br /> We trust this report presents the information required at -this <br /> time. If you have any questions regarding this report and the <br /> attached information, pleaoc aontaot ue. <br /> Respectfully submitted, <br /> RLEINFELDER, INC. <br /> Steven R.
