Did you know contaminated sites can naturally clean themselves over time?
š± Understanding NSZD: Nature's Cleanup Process
Natural Source Zone Depletion (NSZD) is a process where petroleum-based contaminants (NAPLs) are reduced through natural biodegradation, volatilization, and dissolution.
For many years, it was believed that NAPLs could only biodegrade after first dissolving into groundwater. Research has since shown that natural processes can remove contaminants more effectively than previously understood, providing valuable insights for site remediation.
A better understanding of NSZD helps environmental professionals make more informed remediation decisions, optimize site management strategies, and potentially reduce long-term remediation costs while supporting more sustainable outcomes.
