L In a letter dated February 15, 1995, the SJCPHS noted "Staff field notes indicated slight odors (petroleum hydrocarbons) detected yet analytical data generated fail to support these observations", at locations assumed to correspond with sample locations #7, #8, and #10. L The SJCPHS requested additional sampling be performed adjacent to the southwestern dispenser island (at locations #7, #8, and #10) to eliminate conflicting or contradictory L
