4yrAll-1. HIG h TECh ENTERPRISES <br /> 0 <br /> 21 February 2003 <br /> To: Mr. Ajay S. Ranchhod <br /> 4225 E. Hammer Lane <br /> Stockton, CA 95212 <br /> (209) 570-2258 ' Cell Phone <br /> From: Edward W. Finucane, PE, QEP, CSP, CIH <br /> Subject: Report#030203-L-F, concerning the analysis of the contents of the septic tank that <br /> serves both of the following two living units: <br /> 18019 So. Manthey Road 18043 So. Manthey Road <br /> Lathrop, CA 95330 Lathrop, CA 95330 <br /> On-site sampling of the septic tank (on 12 February 2003) and the analysis (on 18 February 2003) of <br /> the contents of the same tank that serves the two units listed above produced results that show alarm- <br /> ing levels of seven common organic chemicals (see the tabulation below and the Appendix to this Re- <br /> port for the complete analytical results, namely, GeoAnalytical Laboratories, Inc. Report No. P043- <br /> 03).The following non-zero concentration level results of this sampling are shown below: <br /> No. EPA Method Analyte Detection Limit Actual Results <br /> 1 EPA 8260B toluene 1.0 pg/liter 193 mg/liter <br /> 2 o-xylene 1.0 pgAiter 127 mg/liter <br /> 3 isopropylbenzene 1.0 pg/liter 15.8 mg/liter <br /> 4 p-isopropyltoluene 1.0 pg/liter 16.4 mg/liter <br /> 5 n-propylbenzene 1.0 pgAiter 20.0 mg/liter <br /> 6 1,2,4-trimethylbenzene 1.0 pgAiter 43.7 mg/liter <br /> 7 1,3,5-trimethylbenzene 1.0 pg/liter 32.9 mg/liter <br /> In my judgment, ALL of these organic chemicals are likely components of a common commercial <br /> product known generically as "white gasoline"—i.e., Coleman Lantern Fuel, etc. <br /> Results obtained under EPA Methods 8260B were developed using a combination gas chromatogra- <br /> phy and quadruple mass spectrometry. Please note that the units of concentration listed above differ <br /> from those in the Lab Report. The tabulation above shows results as "mg/liter", a unit that is, in ef- <br /> fect,milligrams per kilogram,or, basically,Varts per million by weight or mass. The Lab Report pro- <br /> vided results in parts per billion by weigh or mass. My best guess is that some volume of"white <br /> gasoline" was dumped, either directly into the septic tank, or transferred to it by having dumped this <br /> material into any of the plumbing fixtures in either of the two structures serviced by this septic tank. <br /> Should you have any questions on any of the data, or any of the conclusions of this Supplemental <br /> Report,please do not hesitate to contact me. Thank you very much for permitting me to be of service <br /> to you in this matter. oF�O <br /> QR N fr''gCSp~ <br /> Sincerely, � pWFiN�Fy � <br /> (d �j', ,, ' w w No. 13749 rn ® t <br /> �/"' `J �'�'�"` d2c-2- Exp: 12-31-03 i'-+--- -- ---- --L. <br /> p EDWARD—W.FINUCANE <br /> Edward W.
