Groundwater Monitoring &Remediation, Volume 45, Issue 3, Page 58-68, Summer 2025.Abstract A series of field measurements were used to evaluate the mutual interaction between the perched water zone and the regional aquifer under the specific site conditions of the contaminated site. The perched water zone apparently developed after the demolition of a building used for chemicals by leaving low permeability relics of the building ...

Indoor Air Background Concentrations of Volatile Organic Compounds (VOCs) in California Residences
Groundwater Monitoring &Remediation, Volume 45, Issue 2, Page 40-55, Spring 2025.Abstract A study was performed to measure typical “indoor air background” concentrations of volatile organic compounds (VOCs) in residential buildings in the state of California that were not known to be impacted by subsurface sources. A total of 57 buildings were sampled between February 2023 and February 2024, with one sample collected per building ...
