To: Adrienne Ellsaesser [EH] <br /> `Subject: RE: Spingolo Trucking, 1011 Broadway, Stockton <br /> Odd results yes, but 69 mg/kg TPHg at 60 feet bsg seems real enough; the 65-ft data may be due to cross contamination <br /> from shallower depth—but then the well bore will still have passed through an impacted zone. Assuming the well <br /> casing/screen extends to or through 60 Feet bsg, we'd require removal of the well contents. Many wells penetrate or are <br /> screened in impacted soil but yield ND analytical results for water samples. I think there are several possible contribution <br /> factors that may account for this: <br /> 1) The sorbed contaminants in soil have been reduced by natural attenuation and dissolving into water such that the <br /> flux rate is equaled or exceeded by the natural attenuation rate; <br /> 2) The water sampled in the well was derived primarily from un-impacted zone(s)which diluted what contaminants <br /> did flux into water below the detection limit;or <br /> 3) A combination of 1)and 2); or <br /> 4) The well screen is submerged, the well is pumped at the bottom, but fails to evacuate the casing, and the sample <br /> was collected by bailer, which essentially samples unpurged casing water long subjected to biological <br /> degredation. <br /> Nuel <br /> From: Adrienne Ellsaesser [EH] <br /> Sent: Friday, October 25, 2013 1:03 PM <br /> To: Nuel Henderson [EH] <br /> Subject: FW: Spingolo Trucking,. 1011 Broadway, Stockton <br /> So would over drilling be required of MW-3?Given Jims soil results? Seems odd that the water is ND if at 47 ' <br /> with soil contaminants at 60 '. Water should be impacted right? <br /> From: Barton,Jim@Waterboards [mailto:jim.barton@waterboards.ca.gov] <br /> Sent: Wednesday, October 23, 2013 8:27 AM <br /> To: Adrienne Ellsaesser [EH]; Nuel Henderson [EH] <br /> Subject: RE: Spingolo Trucking,_1011 Broadway, Stockton <br /> Hi Adrienne, <br /> Yes this is the case where the owner is not responding to our directive (letter dated,12-20-2012)to destroy the <br /> wells.
