Box 1966S0 Anchorage, Alaska 99S~-6650 Reft Health Authority Approval (HAA) Application for Lot Lang Subdivision To whom it may concern: 1. WELL ADEQUACY TEST: Attached is the HAA application for the subject lot. An adequacy test was run on the well by pul~ping 4.905 GPM (average flo~ rate) for a total of 138 minutes. The total volume pumped was 677 gallons. The static water level, at the beginning of the test, was too.es feet from the top of the well casing. The drawdown on the well, at the end of the adequacy test, was 101.85 feet from the top of the well casing. Thirty minutes later, the well had completely recovered to lO0.S$ feet. Based upon this data, it can be concluded that the well is capable of producing 450 GPO, as required for a three bedroom home. 2. SEPTIC SYSTEM ADEQUACY TEST: The septic system ~dequacy test was performed concurrently with the well test. Water was introduced into the clean-out, located at the end of the trench, at a rate of 4.905 GPM for a total of lJB minutes (677 gallons). The water level in the system was monitored with a float located in the monitoring tube. During the test the water level in the monitoring tube rose a total of 8.5 inches (79.6 gallons per inch). The recovery of the system was monitored fo~ 90 minutes after the water was shut off, and the results were plotted on log vs. log paper (attached). Based upon this data, the system is adequate for a three bedroom house (450 GPD). 3. SEPARATION DISTANCE TO WELLS AND SEPTIC SYSTEMS ON ADJACENT LOTS: As can be seen from the attached as-built survey, there are no developed lots within lO0 feet of my client's well. The closest well is located on the lot (a BLM tract) to the west of Lot i, Lang 8/D. It is my belief that this is a class "C" Nell which serves two private Telephone - Fax 3~8-3-0-46 · 84? 1 Brookridge [')rive · Anchorage. Al:tskn 99504 O~ nO OJ NOIS3E!
