GROUNDWATER INFORMATION The Map, Lines of Equal Depth to Groundwater, Spring 1999 shows approximately 105'to static �- water. Jahant Slough drains did drain the area but much of the smaller channels to the Slough have been filled in. The pond on the southerly portion was probably part of the surface drainage at one time. The surface runoff flows westerly. y The well ted by FarW s r DBCP and Nitrates. The results were: Nitrates- .5 m and DBC -<0.01 u The water is potable with respect to these two tests. There is no c of title as there is no third party involved in the sampling and testing of the well. The lab furnishes a log sheet which is included in this report. ` SOIL PROFILE INFORMATION PThe soil removed from the holes is classified at the time of removal and also the difficulty in r, drilling the holes helps define the soil. The soil observed at the site is classed as silt loam. It is mostly clay with silt and interspersed layers of sand. The field profile is noted as follows: s L K1=5.5 feet Sandy Clay, moist L16-8.5 feet Hard drilling, clay "5-11.5 feet Sand 11.5-25 Clay, with hard pan layers and interspersed with sandy silty clay layer near 25'. Pits are required to provide access to the sand layer. PERCOLATION TEST INFORMATION /The location of the test hole is plotted on the T.M. A 42" hole and a 25'hole were drilled and after examination of the soil a hole to the sand layer was augured for testing. All holes conformed ` to EHD Policy 02-02. The percolation test date was 5-12-06. The holes were pre-soaked for 24 hours, starting at 0900 on 5-11-06. All holes were sleeved(see Smith& Associates hole prep sheet)with PVC and 2" of gravel was placed in the bottom of each hole prior to sleeving. All holes were dry at 0900, 5-12- 06. km The test form has been signed by the EHD representative who was present for the last two readings. Acre does not appear to be any need for an engineered system to be considered. An on site system is performing satisfactorily at present on the subject parcel. If a second dwelling is constructed in the future the test location is indicative of a probable satisfactory strata being present to support the SFR. 2.
