Concentrations of BTEX constituents <br /> ranged from non-detect to 0.075 mg/kg. Total lead was detected at 11.1 mg/kg. <br /> Based on the fact that: 1) the site is known to contain impacted soil and groundwater; 2) <br /> there is an operating groundwater remediation system onsite; and 3) the analytical results <br /> indicate that the stockpiled soil contains less hydrocarbons than that present in soil beneath <br /> the fuel dispenser and product Lines, EMCON respectfully requests permission to backfill <br /> the fuel dispenser and product line trenches with the stockpiled soil. f <br /> x <br /> If you have any questions regarding this matter, please contact us. Your timeliness on this <br /> issue is very much appreciated. f <br /> Sincerely, l <br /> EMCON <br /> Harold R.
