In this work, the presence of selected emerging
contaminants has been investigated in two reservoirs, La Fe
(LF) and Rio Grande (RG), which supply water to two drinking water treatment plants (DWTPs) of Medellin, one of the
most populated cities of Colombia. An analytical method
based on solid-phase extraction (SPE) of the sample followed
by measurement by liquid chromatography coupled to tandem
mass spectrometry (LC–
MS/MS) was developed and validated for this purpose. Five monitoring campaigns were performed in each reservoir, collecting samples from 7 sites
(LF) and 10 sites (RG) at 3 different depths of the water column. In addition, water samples entering in the DWTPs and
treated water samples from these plans were also analysed for
the selected compounds. Data from this work showed that
parabens, UV filters and the pharmaceutical ibuprofen were
commonly present in most of the reservoir samples. Thus,
methyl paraben was detected in around 90% of the samples
collected, while ibuprofen was found in around 60% of the
samples. Water samples feeding the DWTPs also contained
these two compounds, as well as benzophenone at low concentrations, which was in general agreement with the results
from the reservoir samples. After treatment in the DWTPs,
these three compounds were still present in the samples although at low concentrations (<40 ng/L), which evidenced
that they were not completely removed after the conventional
treatment applied. The potential effects of the presence of
these compounds at the ppt levels in drinking water are still
unknown. Further research is needed to evaluate the effect of
chronic exposure to these compounds via consumption of
drinking water. [-]
