Percolation <br /> tests were run on both. The 25 ' failed and the 5 ' -6" <br /> test hole has a percolation rate of 30 minutes per <br /> inch. <br /> Parcel No. 2 Six exploratory test holes were dug on Parcel No. 2 . <br /> They were at depths of 4 ' -211 , 5 ' -5" , 7 ' -0" , 8 ' -4" , 9 ' -6" , <br /> and 25 ' -0" . Percolation tests were performed on the <br /> 9 ' -6" hole and the 25 ' hole . Both tests failed . <br /> Parcel No. 3 Two preliminary holes were dug on Parcel No. 3 . <br /> were at depths of 9 ' -10" and 24 ' -6" . A percolation <br /> test was performed on the 24 ' -6" hole . The test <br /> failed . A test was not performed on the 9 ' -6" hole <br /> because clay was encountered for the entire depth. <br /> Three foot tests were not performed on any parcel <br /> because heavy clay was encountered at this depth on <br /> all 10 exploratory holes . <br /> A discussion was held on July 16, 1993 at the Health <br /> Department office between Manuel Valadao , owner , <br /> Dwain Tosch, Civil Engineer, and Carl Borgman, <br /> Supervising Enviromental Health Specialist regarding <br /> percolation tests . Mr . Borgman informed Manuel Valadao <br /> and Dwain Tosch that percolation tests had to be <br /> performed on 25 ' deep holes and if the test failed <br /> a 12 , 000 square foot septic area should be used . <br /> This was reaffirmed on July 21 , 1993 by Mr . Borgman <br /> to Manuel Valadao. <br /> A soil profile was not performed because depth to <br /> well water is in excess of 110 ' . <br /> Water Analysis <br /> A domestic well and an irrigation well were sampled <br /> for Nitrates and DBCP. Test results were : Nitrates - <br /> Domestic Well - 6 . 1 mg/L, Irrigation Well - 23 . 8mg/L. <br /> DBCP was not detected in either of the wells . <br /> Recommendations <br /> Parcel No. 1 - Leach lines and pits are recommened . <br /> Parcel No. 2 - A 12 , 000 Sq. Ft . minimum usable area <br /> with leach lines and pits . <br /> Parcel No. 3 - New Home - A 12 , 000 Sq.
