Fate and transport of TCE aqueous and non-aqueous phases in a karstified limestone physical groundwater model under different flow rates
(2019-12-06)
This research assesses the fate and transport of non-aqueous and dissolved trichloroethene (TCE) in a karstified limestone physical model (KLPM). The KLPM integrates a limestone block (15 cm x 15 cm x 77 cm) and simulates ...
Enhancement of TCE volatilization and vapor extraction from variably-saturated clay using salt and alcohol solutions
(2015)
One of the most common dense non-aqueous phase liquids (DNAPLs) found in polluted underground systems in the U.S. is trichloroethylene (TCE). Most of the remediation technologies for chlorinated solvents like TCE have been ...
Detection and monitoring of DNAPLs in the subsurface under transient conditions using cross well radar
(2008-04)
Contamination of soils and groundwater, accidental spills, poor storage facilities, and inadequate disposal practices cause serious detriment of the environment and can pose a serious threat to human health. Common ...
Relationship assessment between contamination of groundwater ant tap water in Karst systems
(2018)
Karst groundwater systems are a significant source of drinking water, but also are highly vulnerable to contamination.Contamination may reach tap water and pose potential threat to
public health. This study aims at ...
Assessment of potential exposure pathways in karst groundwater systems in Northern Puerto Rico using GIS
(2011)
The North Coast Karst Aquifer System of Puerto Rico is the most productive aquifer of the island. Same characteristics that makes it highly productive, makes it vulnerable to contamination. This research assess potential ...
Effect of variable environmental conditions on fate and transport of explosive-related chemicals near soilatmospheric surface
(2009)
Landmines and other buried explosive devices (BEDs) pose an immense threat to military personnel, civilian population, and the environment in many places of the world, requiring large efforts on detection. Chemical detection ...
Vapor phase transport of explosive related compounds through unsaturated sandy soils
(2008-08)
Chemical detection of buried explosives devices through chemical sensing is influenced by factors affecting the transport of chemical components associated with the devices. Explosive-related chemicals (ERCs), such as ...
Efficiency evaluation of an advanced oxidation processes (AOP) package plant for MTBE removal from natural waters
(2007-05)
To provide safe drinking water to small communities in Puerto Rico, this project evaluates the performance and reliability of a small-scale, advanced oxidation processes (AOP) package plant for water treatment. Specifically, ...
Monitoring phthalates and chlorinated volatile organic compounds in groundwater and tap water
(2015)
Pollutants such as phthalates and chlorinated volatile organic compounds (CVOCs), which threaten the public health and the environment, have to be monitored and analyzed to minimize their exposure. Phthalates and CVOCs are ...
Historical assessment of chlorinated volatile organic compounds (CVOCs) and phthalates contamination in the northern karst aquifer of Puerto Rico using GIS
(2014-12)
Contamination in Puerto Rico (PR) is extensive with more than 150 contaminated sites and a vast contamination of water resources. Among the most impacted areas is the northern coast karst aquifer. This project (1) evaluates ...
