Delivering Sulfate to LNAPL Body for Enhanced Source Zone Depletion (ESZD)

Groundwater Monitoring &Remediation, EarlyView.
Abstract This field pilot study evaluates the feasibility of applying sulfate to a light non‐aqueous phase liquid (LNAPL) body for achieving enhanced source zone depletion (ESZD) at a refinery site. Two rounds of gypsum land application (GLA) delivered sulfate to an 8000 ft2 area encompassing LNAPL‐containing monitoring wells MW‐2 and MW‐3, while MW‐1 ...

Microaerobic biodegradation of aromatic hydrocarbon mixtures: strategies for efficient nitrate and oxygen dosage

Applied Microbiology and Biotechnology
The biodegradation of organic aromatic compounds in subsurface environments is often hindered by limited dissolved oxygen. While oxygen supplementation can enhance in situ biodegradation, it poses financial and technical challenges.

Development of a Bioreactor-Based Model for low-density polyethylene (LDPE) Biodegradation by Aspergillus brasiliensis

Universitas Scientiarum
Low-density polyethylene (LDPE) is a widely used polymer due to its chemical resistance, highflexibility, and mechanical properties. However, its low degradation rate, coupled with its low lifespanand widespread accumulation, poses significant ...
