Because of this the waiver fee will be applied toward lot 6. The depth of the leach field is approximately to feet. The tank and the absorbtion field were installed May 27°, 1981. The well on lot 8 also encroaches this septic system on lot 8. this encroachment has been in existence since 1981 ans has a waiver for this encroachment. The well on lot 8 is alos down gradient to from the septic system. Lot 8 well was tested on a previous IIAA and had low nitrates. Well Data Lot 6 well: Well data in the area show low nitrates and the well on lot 6 showed low nitrates on a previous IIAA.

Box 196650 Anchorage, AK 99519-6650 Attention: Joe Goodall RE: Ptarmigan View Estates, Lot 8 Waiver Request— Nitrates Information Dear Joe, I requested a waiver for the distance from the subject lot's septic drainfield to the well on Ptarmigan View Estates Lot 6, to a distance of 90 ft. In conjunction with that waiver request, I sampled the water from Lot 6 and had it ana!yzed for bacteria and nitrates. The analysis yielded 1 colony oother bacteria' and 7.65 mg/l nitrates on April 6, 2005. Although the nitrates are less than the allowable limit of 10 mgn, the level is higher than other wells in the area. Therefore, you asked for further information regarding a potential source of the nitrates. I surveyed the area on April 21, 2005, and found that the distance between the septic tank cleanout on Lot 6 and the center of the well on Lot 6 is 75.67 ft, when measured with a total station. This could potentially be the source of the nitrates in the well. do not believe that the source of the nitrates in the well are from the drainfield on Lot 8, due to the fact that the drainfield is 13 ft downhill from the well, and the well is 203 ft deep with impermeable layers between the aquifer and the surface. The house on Lot 8 has been sold, and an application has been made for a Health Authority Approval. The well on Lot 6 was drilled after the septic system was installed on Lot 8, and I do not believe that the sale of the property should be delayed due to the encroachment. If you need further information, please call me Yours truly, G MI'el va`�y Cindy Vt. Ellis, P.E. President Watkins Engineering, Inc. P.0 Box 110443, Anchorage, AK 99511 (907)349-1851 cwellis@gcl.net April 18, 2005 Municipality of Anchorage Development Services Department Building Safety Division On -Site Water and Wastewater Program P.O. Box 196650 Anchorage, AK 99519-6650 RE: Ptarmigan View Estates, Lot 8 Waiver Request for Absorption System to Lot 6 Well To Whom It May Concern: We respectfully request a waiver for the distance from the soil absorption system on the subject lot to the private well on the adjacent Ptarmigan View Estates, Lot 6, to 90 ft. The soil absorption system for Lot 8 was installed and approved on May 27, 1981. The well for Lot 6 was drilled and completed on September 19, 1981. Therefore, the owner of Lot 8 is not responsible for the waiver fee. I believe that the reduced distance from the well to the soil absorption system will not lead to contamination of the well or the aquifer for the following reasons: 1) Satisfactory water analysis from the subject well, 2) Well depth of 203 ft provides substantial vertical separation, 3) Soil strata between the aquifer and the surface provide an adequate barrier, and 4) Difference in elevation, with the well 13 ft or more higher than the ground level at the trench. _ The water analysis on the Lot 6 well from a sample on 4/7/05 reported 7.65 mg/l nitrate, 0 coliform, and 1 colony/100 ml other bacteria. The lab report is attached. The Lot 6 well log is attached, showing clay and silt from 72 ft to 196 ft which provides a barrier to vertical migration of septic effluent. The well has a total depth of 203 ft. When drilled, the static water level was 68 ft in the bottom of the well, or 135 ft from the top of the casing. The current static water level on Lot 8 is 120 ft. Watkins Engineering, Inc., April f8, 2005 Ptarmigan Yew Est Lot 8 Waiver Request, page 2 of 2 The topography of the area prevents migration of fluids from the soil absorption system toward the well. Relative elevations are shown on the attached site plan. There is a difference of 13 ft or more between ground level at Lot 6 well and Lot 8 soil absorption system. Based upon these facts, I believe that the potential for contamination of the subject well and the aquifer is minimal. Therefore, I request that the required distance from the well to the soil absorption system be waived to the existing 90 ft. Thank you for consideration of this request. If you need any further information, please call me at 349-1851. Sincerely, �4 Cindy W?nis,P.E.
