The waiver has been amended to include the encroachment of the west end of the absorption field on lot 25 to the water well on lot 24 of 95 feet. This amended waiver letter also serves to grant a lot line waiver from the absorption trench on lot 25 to the east property line that fronts Miller Road. The approved separation is 5 feet. This waiver approval applies to the existing on-site wastewater disposal system to well separation and lot line separation only. Any future upgrade to the absorption field will require all separation distances be met or another approval from this department. If there are any further concerns of questions regarding this waiver, please call our office at 343-4744. Sincerely, Daniel J.

Health & Human REFERENCE: Lot 25; Lake Hill Acres #1 Request for waiver modification WR 970019 Request for property line waiver In June, 1997 your department issued a 95 foot waiver (WR 970019) for the separation distances 15om the private well on Lot 24 Lake Hill Acres to the drainfields on Lots 24 & 33, Lake Hill Acres #1. Recently we were comracted to test the well and septic on Lot 25, Lake Hill Acres for purposes of obtaining a Health Authority Approval. Prior to testing the septic system, the missing monitoring tubes and cleanouts had to be installed at the end of each trench. Once installed, it was evident that an encroachment existed to the well on Lot 24. Request you modify the existing waiver (WR 970019) to include the septic system on Lot 25; Lake Hill Acres #1. Also we request you issue a property line waiver on the subject property for the separation distance between the leachfield on Lot 25; Lake Hill Acres #1 and the east property line to five (5) feet. We do not anticipate any adverse effects by issuance of this waiver, as the property line is adjacent to a road right-of-way (Miller Road).

Health & Human Services Division of Environmental Services On-Site Services Section P.O Box 196650 Anchorage, Alaska 99519-6650 Attn: Dan Roth Subject: Waiver of separation distance from private well on Lot 24, Lake Hills Acres #1 to drainfield on same lot, and drainfield on Lot 33, Lake Hills Acres #1. Dear Dan: The subject property has a 3 bedroom house, served by a private well and septic system. The drainfield was installed in 9/82 and the well was drilled later on 10/30/82. The distance from the drainfield sump, to the xvell is approximately 98 feet. Since the trench is 30 inches wide, it is reasonable to assume that the edge of thc rock is only about 96.5 feet from the well. To be conservative, I am going to assume the separation distance is 95 feet. In addition to this encroachment, the well is also only 98.5 feet from the septic c/o on Lot 33, Lake Hills Acres. This measurement was performed using DHHS's surveying instrument (Dan Roth was present). The location of the remaining portion of the trench on Lot 33 is unknown. Again, I am going to assume a separation distance of 95 feet. Justification for this waiver is summarized as follows: GENERAL: Given the fact that the house on Lot 33 has a daylight basement, it is highly unlikely that the drainfield will ever overflow onto the ground surface, since in order for this to occur, the basement (home on Lot 33) would have to flood (several feet deep) with sewage. The subject well is uphill from the septic system on Lot 24, consequently, it is not possible for overflowing sewage to run towards the well. The only feasible path of contamination would be subsurface migration of the wastewater from the drainfields towards the well. Analysis of the contamination potential will be evaluated based upon the ADEC point system. R, POINT SYSTEM EVALUATION: Geological: According to the well log, the water table is approximately 160 feet below the ground surface. On the day of my inspection (4/19/97) the water was 178 feet below:the top of the casing. Bedrock was not encountered, therefore, the bedrock profile is not a consideration. a. Distance .fi'om the bottom qf the rbait~.filed to groundwater (160 foot static level in n,elO; The bottom of the trench (Lot 24) is approximately 8 feet below gradel The separation distance from the bottom of the trench to the static water in the well is approximately 150 feet. This corresponds to 7.26 points. b. &~i/so~ptio~ be/o~, the lre~Tch: According to the well log, the soils (down to the water table) are primarily a mix of sand & gravel, with occasional boulders, and some hardpan. To be conservative I am going to assume a value that is the average of clean gravel (0 points) and clean sand (1.5 points), which corresponds to .75 points. c. Soil permeability below the tre,ch: I am going to treat the entire soils profile as a sandy gravel, which corresponds to a point value of .9 d Water table gradient: When performing the well adequacy test (pumping at a rate of 5.01 gpm for 102 minutes) there was no drawdown. In short, the hydraulic gradient is 0%. This corresponds to 2.9 points. e. Horizontal separation.fi'om u, ell to septic tank: Given a 96 foot separatiOn distance, the point value is 2.8. Total Points: 14.6 According to the ADEC waiver guidelines, a point value 12-16 indicates no bacterial contamination is possible, and that chemical pollution (from household sources) is unlikely. Recent water samplin~analysis (4/14/97) tbund no bacteria, and nitrate levels of .723 mg/l. In short, after almost 14.5 years, the water quality has yet to be effected by this encroachment. copies of the lab results were submitted with the Health Certificate package. Given the facts presented, it is my opinion that there is minimal risk in granting the requested waiver (95 feet from well to septic systems on Lot 24, and Lot 33). If you have any questions, please contact me at 337-6179, or on my digital pager at 1-800-481-1162. Thank you for your assistance. Sincere/~. Princi c.c.
