Sunrise Trucking— Soil Suitability Section Page 6 of 16 Our Project Number: NA157003G October 23, 2015 mg/L-NO3 (3 mg/L-N). Areas having 24.75 mg/L-NO3 (5.5 mg/L-N) or more are those in which nitrate concentrations may be increasing (Hull, 1984). �- ' DBCP (dibromochloropropane) is a nematocide and soil fumigant for vegetables and grapes. It is thought to cause health problems consisting of kidney damage, liver damage, and cancer. The use of DBCP was discontinued in 1979. EDB (ethylene dibromide) was used in gasoline to prevent lead deposits and build up. It was also used in pesticides and fumigants. Exposure to EDB is linked to many adverse health effects stemming from organ damage to cancer. Agricultural activities, industrial activities, and the use of septic systems in the area should be considered potential groundwater contamination sources. The concerns for groundwater contamination in this area are deemed moderate due to the depths involved. 1.4.3 Water Sample Location Based on a review of permits provided by EHD for the site,there is one waterwellon the property. Because groundwater is a source of drinking water for the site, two samples were collected from a spigot adjacent to the well for testing of'DCB'P, EDB, and Nitrate. 1.4.4 Ground Water Sample Analysis The water sample for nitrate was collected in a sterile plastic container; the water sample for DBCP/EDB was collected in two sterile glass vials. Samples were transported on ice and ' remanded under chain of custody to McCampbell Analytical, Pittsburg. A copy of the chain of custody and lab report from McCampbell Analytical has been included in Appendix E. Sample results are displayed in the following table: DBCP* (Ng/L) EDB*(pg/L) Nitrate as N**'(mg/L) 1 MCL= 0.2 pg/L MCL= 0.5 pg/L MCL=.4U' g/L Water Sample 1 X X �4- Water Sample 2 ND ND X ' Bold Detected above EPA maximum contaminant level(MCL) ND Not detected at the laboratory reporting limit.
