This article shows the interesting results of a pioneer effort by IAG/USP researchers to use
ground-penetrating radar (GPR) for humanitarian purposes, guiding the rescue of victims in …

Ground-penetrating radar (GPR) is a non-destructive tool that can be used to help detecting
water leaks in water distribution networks. This study, which was undertaken in the …

Moisture is one of the most important factors causing building stone decay and rain
penetration is one of the leading factors. Particularly, wind-driven rain spells, which are …

222Radon (Rn) was proposed in the late 1990s as a naturally occurring tracer for light non-
aqueous phase liquids (LNAPLs) in the subsurface, due to its preferential partitioning …

The application of the 222 Radon (Rn) deficit technique using subsurface soil gas probes for
the identification and quantification of light non-aqueous phase liquids (LNAPL) has …

Contamination of groundwater by harmful substances poses significant risks to both drinking
water sources and aquatic ecosystems, making it a critical environmental concern. Most on …

The present work studies the remediation of a B20 (20% biodiesel, 80% diesel) biodiesel

Nonaqueous-phase liquids (NAPLs) usually move through the vadose zone not in a
homogeneous spread manner but in the form of disconnected blobs, and they remain in the …

The management and remediation of abandoned hydrocarbon-contaminated sites require
detailed information on the distribution of contaminant plumes. In areas where groundwater …
