(SSS§ 4.2, 4.3, 4.4, 4.5, 4.6). As noted, there.are two wells on the subject property-.A domestic well in the southwe t.:cornerof Parcel A and an irrigation well that is:shown to be presently on the property-line between Parcels.A and B. The property line is.proposed-to-be changed by Mike Farley, P.L.S. to illustrate a'.10-ft setback from this irrigation well. On January 15, 2010, these two wells were sampled under EHD guidelines: . Each well was turned-on,and allowed to pumped water for 15 minutes prior to sampling to ensure ' that aquifer forrnation water.was sampled°and not stagnant well water. The domestic well was sampled from a discharge.tube next to the well head. The irrigation well was sampled from the drip line emitter next to the well.- Plastic bottles were used`for the nitrate samples, and VOC bottles with preservative were used for:the DBCP samples. The VOC bottles were filled completely so that there was no-head space.- Both samples were placed in a cooled ice chest and then transported to: A & L Agricultural Laboratories on January 15, 2010, under the Chain of Custody found in Appendix 4. Table 2 below illustrates the test results for each of the sampled wells: TABLE-2 :WELL-WATER TEST RESULTS WELL TESTED,LOCATION: NITRATE DIBROMOCHLOROPROPANE AND SAMPLE ID NUMBER CONCENTRATION (DBCP)CONCENTRATION- Domestic t Domestic Well on'Proposed Parcel .A . 19 ppm as Nitrate BDL SAMPLE ID: (MCL=45 ppm) (MCL=0.2 ppb) DOMESTIC WELL MCL=MaXiinum Contaminant BDL= Below Detectable Limits Level Detection limit=0.01 pg/L Irrigation Well Currently Shown on 19 ppm as Nitrate .Not Tested in Accordance with Property Line Between.Propose'd (MCL=45 ppm) EHD Requirements Parcel,13 and C SAMPLE ID: IRRIGATION WELL {§ 7.0) CONCLUSIONS The perc test results for three of the four proposed Parcels indicate passing or acceptable permeability at the shallow depths representative of leachlines (or chambers) for Parcels A, C and D. Parcel B bad failing rates for both shallow and deep test borings. Only Parcel C had acceptable perc rates at the deeper test depths representative of sumps. Deeper perc tests were conducted at sump depth (approx. 10-12 ft)because the soil structure, consisting of a silty sand-sandy silts possessed what appeared to be sufficient permeability, while soil below the 12-14 ft depth down to 25 ft consists of a clay material. Deep perc test results reveal that the silty sand-sandy.silt material is too.dense because of the encountered cemented silts hardpan to allow acceptable permeability, except on proposed Parcel C.
