The influence of hydrogeological and anthropogenic variables on phthalate contamination in eogenetic karst groundwater systems.

ABSTRACT: This study investigates the occurrence of six phthalates and distribution of the three most-detected phthalates in the karst region of northern Puerto Rico (KRNPR) using data from historical records and current field measurements. Statistical data analyses, including ANOVA, Chi-Square, and logistic regression models are used to examine the major factors affecting the presence and concentrations of phthalates in the KRNPR. The most detected phthalates include DEHP, DBP, and DEP. At least one phthalate specie is detected above DL in 7% of the samples and 24% of the sampling sites. Concentrations of total phthalates average 5.08 ± 1.37 μg L^-1, and range from 0.093 to 58.4 μg L^-1. The analysis shows extensive spatial and temporal presence of phthalates resulting from disp
