Dry Cleaner Site (Solvents/Bio) - Case Study
Aestus was asked to assist with a dry cleaners site which was operational from 1945 to 1977. The state led cleanup involved a soil excavation and series of bioremediation injectates. The existing monitoring well network showed PCE concentrations above regulatory standards following the remediation attempt. Aestus used our non-invasive ultra-high resolution subsurface scanning method to image the ...

Low-Cost Microbiotests For Toxicity Monitoring During Bioremediation Of Contaminated Soils
Abstract: This paper addresses in the first place the need to apply toxicity tests with batteries of species from different trophic levels for an (ecologically meaningful) determination of the toxic hazard of contaminated soils. Furthermore, \'direct contact\' tests must be performed as well as assays on pore waters, leachates or percolates.Most toxicity tests available to date are dependent on ...

Bioremediation of soil
In our experience, Bioremediation is best accomplished with Bio-augmentation, the addition of large numbers of selected micro-organisms grown in the production laboratory. In addition to bio-augmentation, several physical and chemical parameters must be controlled in order to obtain optimal growth and maximum degradation of soil contaminants. The major factors that are controlled during ...

Real Estate Development: Southern California Campus at Former Aerospace Manufacturing Facility - Case Study
In 2015, Intrinsyx was retained by a Fortune 100 client with a campus being developed (late 2018 opening) at a highly contaminated former aerospace manufacturing facility. We worked with the client’s Environmental Health & Safety team, their architectural firm, their landscaping firm, as well as state and federal regulators. We developed a tailored planting scheme for their campus using ...

Brownfield Site Phytoremediation for Oil Company - Case Study
The site was a petroleum tank farm from the early half of the 20th century. Contaminants on-site include petroleum hydrocarbons, benzene and ethylbenzene, and PAHs naphthalene and 2-methylnapthalene. Most contaminants are in subsurface and groundwater, with the exception of PAHs that extend from the surface to ...

MEW Superfund Site: TCE Groundwater Plume - Case Study
Working with NASA-Ames Environmental Remediation Group and the EPA, this site was our first field deployment of Endophyte Assisted Phytoremediation, at one of the region’s largest Superfund sites with TCE groundwater contamination. Intrinsyx planted 300 hybrid poplar trees as 12-inch cuttings. Within a year, the benefits of using our PDN3 bacterial endophyte to inoculate trees were visible, ...

CH#954 - Diesel/Gasoline Remediation
SITE OWNER: A Truck and Fueling Plaza SITE SURVEY: A tank area that had contained both diesel and gasoline tanks was discovered to have several leaks. The tanks from the pit area were removed. Definition and characterization revealed that not only the tank area was contaminated, but the contaminate plume had migrated under an area where a new building was being constructed. Initial ...
