dc.description.abstractKarst 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 determining the link between groundwater and tap water contamination in the northern karst region of Puerto Rico. The study focuses on Chlorinated Volatile Organic Compounds (CVOCs) and phthalates due to their ubiquitous presence in the environment and potential for health impacts. Water quality data in groundwater and tap water is collected from historical records and field measurements, and analyzed statistically and spatially. Results show that contamination in groundwater with CVOCs is more extensive than with phthalates. Except for trichloromethane (TCM), CVOCs are more frequently detected in groundwater, whereas phthalates and TCM show higher detection in tap water. Results show that groundwater contamination is reaching tap water sources, but the amount reaching these sources is contaminant-dependent.en_US
dc.description.abstractLos sistemas de agua subterránea son una fuente significativa de agua potable, pero altamente vulnerables a la contaminación. La contaminación puede alcanzar el agua potable y representar una potencial amenaza a la salud pública. Este estudio pretende determinar la relación entre la contaminación de agua subterránea y el agua potable del sistema del karso de la costa norte de Puerto Rico. El estudio se enfoca en los compuestos volátiles orgánicos clorinados (CVOCs) y los ftalatos debido a su ubicua presencia en el ambiente y potencial impacto a la salud. Datos de calidad de agua subterránea y de agua potable son colectados de archivos históricos y de medidas de campo, y analizados estadísticamente y espacialmente. Los resultados muestran que la contaminación de agua subterránea con CVOCs es más extensa que la de los ftalatos. Excepto por triclorometano (TCM), CVOCs son más frecuentemente detectados en agua subterránea, mientras que los ftalatos y el TCM muestras mayor detección en el agua potable. Resultados muestran que la contaminación de agua subterránea ha alcanzado las fuentes de agua potable, pero la cantidad de las fuentes es dependiente del Contaminante.en_US
