1. The document describes a case study using a Fuel Fluorescence Detector (FFD) to rapidly delineate diesel impacts in soil over the course of a remediation project. 2. The FFD was used to delineate diesel impacted soil within 3 days, and collaborative soil sampling was conducted to correlate FFD responses to analytical results to establish a threshold for impacts. 3. Real-time FFD data was integrated into engineering estimates and remediation bid specifications, allowing soil volumes and the remediation scope to be accurately defined, saving an estimated $250,000.
