All Case Studies NSZD Monitoring (Fossil Fuel Traps) UV Surveys (Clear-Well)
A field study started in 2023 to demonstrate the Clear-Well technology. Two locations were installed using a direct-push rig.
A soil column was contaminated with LNAPL. Multiple cycles of water table levels were conducted, to generate a wide zone where the NAPL was observed.
A soil column was initially contaminated with LNAPL. After an initial survey was conducted, the water level was dropped.
A soil column was surveyed multiple times a week using both white and UV lights (365 nm), after planting a basil plant on top.
This is an old 60 acre railyard in Oregon, USA. The site owner went into an agreement with the State Agency under the State Voluntary Cleanup Program.
Soil contamination results in significant changes in the soil microbial ecology. Petroleum contaminants, and related organic compounds such as those generated by forest fires, are naturally present in natural environments.
A study was initiated in 2016 to investigate NSZD, based on CO₂ fluxes at the surface, as part of a remediation project at a large oil spill in the Northeast U.S.
CRC Care, an independent organization dedicated to the remediation of contaminated soil, water, and air; published on March 2020 its technical report no. 47.
This is a detailed report about an investigation at a Navy Air Station in which a multi-tiered approach was used to address
A 2015 remediation project on an LNAPL-contaminated site compares different methods to measure NSZD rates.
This presentation describes a phytoremediation project at a petroleum impacted site in California’s San Joaquin Valley.
Fossil Fuel Traps were developed at the Center for Contaminant Hydrology at Colorado State University over a five-year period after researchers there recognized the limitations of
