| ||
| |
| Industry: | Industrial / Transportation |
| |
| Challenge: | Remediate abandoned right-of-way within several city blocks in advance of FDOT highway expansion project |
| |
| Solution: | Install Propagations and vertical wells to remediate soil and groundwater using sequential fenton-like and permanganate treatments |
| |
| | |
| Site Setting or Use: | FDOT Right-of-Way | |
| Location: | Florida | |
| COCs: | TCE and DCE | |
| Treatment Interval Soil Type: | Fine sand | |
| Depth to Groundwater: | 15 ft bgs | |
| Plume Size: | 0.75 acre | |
| Injection Array: | 6 Props.* plus 10 vertical wells | |
| Baseline Conditions: | Total CVOC 300 ug/l | |
| Current or Final Conditions: | All wells either BDL or below FDEP goals | |

| |
| Industry: | Industrial / Clothing Manufacturer |
| |
| Challenge: | Removal of LNAPL No. 6 fuel oil from below building foundation without disruption to business operations |
| |
| Solution: | Series of ConductivPlanz injections achieves results at 60% cost savings |
| |
| | |
| Site Setting or Use: | Clothing Manufacturer | |
| Location: | New Jersey | |
| COCs: | No.6 fuel oil | |
| Treatment Interval Soil Type: | Clay, ash, silt | |
| Depth to Groundwater: | 16 ft bgs | |
| Plume Size: | 13,000 sq. ft | |
| Injection Array: | 6 Conductiv-Planz | |
| Baseline Conditions: | Free Product TPH avg 200,000 ppm | |
| Current or Final Conditions: | Site in final polishing phase | |
| ||
| |
| Industry: | Industrial / Former Printing Operation |
| |
| Challenge: | Site was stalled in monitoring phase for 5 years. ERFS goal was to meet state requirements and finally close out project |
| |
| Solution: | After 3 treatments within 9 months, CVOC remained below standards throughout one year of post-treatment monitoring, resulting in SRCO (NFA) by FDEP |
| |
