Co., MN l <br /> A Compliance Inspection was completed for the existing on--site sewage treatment <br /> system located on this property. The system consists of 2-1000 gallon septic tanks, 1- <br /> 1000 gallon pumping chamber & a pressurized mound system built in 1997. Soil boring <br /> #1 found mottled (redox features) at 1.7' below the ground surface. Soil boring #3 <br /> found the original soil at elev.102,5 &fihe bottom of the rock bed at elev.104.2 leaving <br /> 1.7' of sand below the rock bed & a 3.4' separation from the bottom of the rock bed & <br /> redox features. Soil boring #2 found mottled soil at 2.2' below the ground surface. Soil <br /> boring #4 found the original soil at elev,102,5 & the bottom of the rock bed at <br /> elev.104.2 leaving 1.7' of sand below the rock bed & a 3.9' separ bottom <br /> of the rock bed & redox features, This system is classified sin compliance w� h <br /> Minnesota Chapter 7080 rules. <br /> The tanks were pumped by Elmer J. Peterson Co. who found the 1st & 2nd tanks <br /> leaking & are classified as non-compliant, The tanks will need to be replaced & a Tank <br /> Entegrity Report completed for the compliance to be complete. <br /> On record at the City on June 2, 1998, S-P Testing found the system to be hydraulically <br /> overloaded due to the tanks leaking & poor drainage around the mound, Also sand <br /> was only found 12' from the rock bed, 19' was required. The sand during the inspection <br /> on 9-22-10 was found 10' from the rock bed & a diversion was excavated aroung the <br /> south end off the mound. It appears that the drainage & added sand was completed at <br /> that time but the tanks are still leaking. <br /> Nothing other than gray water (laundry, showers, etc.) human waste & toilet tissue <br /> should be disposed of into the septic tanks. Garbage disposals are not recommended, <br /> due to adding more solids & fine solids passing through to the system. Recommend to <br /> divert iron filters out of the system, recommend to divert the <br /> 1 <br />
