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 ...
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 ...
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 ...
Integrating groundwater resources in existing water supply infrastructure using spatial tools
(2012-05)
Management and development of groundwater resources introduces the challenge of collecting necessary information to understand the system. The information must integrate the aquifer system characteristics and the limitations ...
Development of testbed for assessment of enhanced soil vapor extraction of trichloroethylene in unsaturated clayey soil
(2014)
Trichloroethylene (TCE) is a volatile organic compound (VOC) commonly found in many contaminated sites. It is a dense non-aqueous phase liquid (DNAPLs) considered harmful to human health. DNAPL pose particular threats ...
