� ri it, - J - <br /> C A M B R I A <br /> CONCLUSIONS AND RECOMMENDATIONS <br /> Groundwater samples collected from monitoring wells this quarter generally contained reduced <br /> petroleum hydrocarbon concentrations when compared to last quarter and are within the <br /> historical norm for this site The groundwater flow direction is easterly at an approximate <br /> hydraulic gradient of 0 003 Cambria recommends reducing oxygenate analysis (other than <br /> MTBE) from quarterly to annually This recommendation is based on the quarterly fuel <br /> oxygenate data that has been collected since May 2000 These data suggest that fuel oxygenates <br /> are not present beneath this site in significant concentrations Annual sampling of fuel <br /> oxygenates should be sufficient to monitor any concentration changes Cambria will implement <br /> the reduced fuel oxygenate analyses upon approval from EHD <br /> CLOSING <br /> If you have any questions regarding the contents of this document, please call Joe Neely at <br /> (707) 933-2361 <br /> Sincerely, <br /> am ria Environ ntal Technology, Inc <br /> Curtis Payne <br /> Project Engineer <br /> OD G�G� <br /> Joe W Neely, RG mac, S�eH W �FGc� <br /> Senior Project Geologist <br /> RG 6927 <br /> ° No 6977 ° <br /> OF CALICG� <br /> 0 <br /> 1399 2 <br />
