Box 196650 ANCHORAGE, ALASKA, 99501 July 28, 1988 Subject: Septic System Upgrade Permit Tract B, Hillsborro Tom LaVelle Gentlemen: On July 21 the existing trench on subject lot was exposed due to adequacy test failure. The water level in the standpipe was observed to be at ground level and the water depth in the tank was measured to be 59 inches. Both observations indicating a severely surcharged system. Upon exposure of the trench no evidence of imported sewer rock was seen, it appeared that the the distribution pipe was buried in the on site gravely material. This system was installed in 1976 and approved by the Health Department at that time. Design for an upgrade is submitted. The attached soil log shows a gravely material with a percolation rate less than 2 mtn/in to 9 feet. Below 9 feet is a relatively dense sandy silt which was rated as 150 in 1976. A small seep was observed at the interface of the gravel and the silty material. The seven day monitoring period did not show standing water in the monitoring tube,~ indicating that the_ ~ ..... observed. .... water~ _ was _temp°rary ....... in nature._ . Paragraph 15.65.060 of the AO # 86-21 requires that a filtration layer 2 feet thick be installed when soils with a percolation rate of less than 2 mtn/inch are used for a soil absorption system. Our d~ig~ ~)es ~0~ ~p~cify this filtration la~r since the e~iSting sandy_s~i!t !~yer :!n~[[e~ ~s~ f~l ~perior to an im~0~d layer in PUrifying ~hi~ S~%[~ effluent. we will also argue that in this case a trench can be installed in the gravely soil, and that in a short time sufficient organic build up will occur to s~c~e ~a ~ ~i0~ - di~6ha~g~ tO ~r~d~ ~0i~ ~h~n t~J[S~ t~n&~ ~' e~cavated '~o evidence of septic soils could be seen with in two feet of the stand pipe. The excavation was 10 feet deep and the distance to the standpipe approximately 2 feet when the bank broke and the the pit flooded with septic water, qbvious!x tb~ 9r~ag~q m~t very effectively prevented thesseptic water from percolating Tobben Spurkland P.E. Subject: Septic System Upgrade Permit Tract B, Hillsborro Tom LaVelle pg. 2 Base on the above observation and the fact that the existing sandy/ silty material meets the intent of 15.65.060 we ask for approval of the propose system.

At the beginning of the test water level was found at 120 feet below top of casing. At a pumping rate of 7.25 gallons per minute the water level dropped to 202 feet after 55 minutes of pumping and remained at that level for the remainder of the test, 25 minutes. A total of 550 gallons were pumped. The well recovery rate was monitored for 30 minutes. The well recover to 141 feet during this period, a 74% recovery. TEST FOR E.COLI AND TOTAL NITROGEN: Water was tested for E.Coli and total nitrates on July 23, 1988 E.Coli 0. Total Nitrates .40 mg/1. Max. allowable Total Nitrates 10mg/1. TEST RESULTS: This well meets the requirements of the Municipality of Anchorage. THIS WELL WILL PRODUCE MORE THAN 3 GALLONS PER MINUTE FOR THAN FOUR HOURS MORE The Municipal requirement for well flow is ]_50 gallons of water per bedroom per day. This well exceed this requirement. The assessment of the condition of the well applies only to the conditions as of the day tested. The flow rate may change due to subsurface conditions that may not be observed from the surface, and changes in the land use and other factors that may impact the aquifer feeding the well.
