Anderson Applicant: Myrtle Bearden Your request for a waiver of the required 100 feet horizontal separation from the septic tank to the private well has been approved. The approved separation distance is 68.0 feet. See engineer's waiver request letter for justifications. This waiver approval applies to the existing septic tank only. Any future upgrade to the on-site wastewater disposal system will require all separation distances be met or another approval from this department.

The well is up gradient and located on the opposite side and inside the house from the tank. The nitrate sample results were ND. The plastic tank installed is a better tank than the original steel tank that was allowed to be within 50' of the well at time of construction. Water levels, the soil sorption and permeability of the area would indicate low probability of any influence between the well and septic tank. Area well logs show silty gravel and bedrock and test holes show slow percolating soils (20-40 min / inch). Area nitrate results are also very low and mostly ND. Attached is a representative sample of MOA record docs of the immediate area. The existing well would be almost sure to be free from any form of sewage contamination or influenced by the location of the septic tank. We do not expect there to be any adverse effect on the subject or adjacent lots by the location of this existing well and septic tank and request issuance of the waiver. Please contact Brent M. Western or me if you have any questions. Sincerely, 441144)(--- Michael N.
