We are submitting this permit application for the construction of a new well and septic system to serve the home. The attached site plan identifies the location of the home and the proposed well, septic system and alternate site. No conflicts exist between this proposed system and any other well or septic system on this lot or adjacent lots. The ground surface on the lot slopes gently to the northeast at shallow grades. There are no slopes greater than 25% within 50 feet downslope of either the primary or alternate site. Contours and drainage arrows are shown on the site plan indicating the grade and direction of flow. Stormwater drainage will not impact this septic system. The new trenches will be constructed parallel to the slope as much as possible. The new system will be a minimum of 100' from all wells and surface water, 10' from any water service and more than 5' away from the septic tank. Please refer to the attached test hole logs and plan and profile pages for the septic design. If this design is followed, there will be no adverse impacts to adjacent properties.

A water sample take from the well on 4/12/2022 reflected a climb in nitrate concentration from 0.02 mg/L to 7.34 mg/L. The sudden increase in nitrates is thought to be the potential result of surface water contamination due to a low area around the well collecting seasonal breakup/runoff water. To initigate .the surface water concern, bentonite was placed around the well casing at about 3' below the surface in an attempt to intercept any water that may be traveling down the outside of the well casing. Additionally, about 8 yards of fill was spread around the well to help sheet water away from the well and keep water from collecting near it. The efficiency of this repair may not be measurable until similar runoff circumstances occur later in the year or during the next breakup season. The intention of this repair is to take steps toward mitigation in an economical and incremental manor, as it is difficult to guarantee the level of effectiveness of any action taken concerning aquifer or well contamination.
