Characterization of Groundwater Quality and Human Health Risk Assessment

The study aimed to appraise groundwater quality in the Mekong Delta using a index (GWQI) and estimate human health risks associated with consumption. Groundwater samples were collected at sixty wells distributed An Giang, Kien Hau Giang Dong Thap provinces. Twelve water parameters measured, including pH, total dissolved solids (TDS), hardness, coliform, nitrate (NO3ˉ), nitrite (NO2ˉ), ammonium (NH4+), sulfate (SO42-), iron (Fe), manganese (Mn), arsenic (As) cadmium (Cd). results compared national regulation on quality. findings of this indicated that was contaminated microorganisms some heavy metals (Fe, Mn, As). This related anthropogenic activities, such as improperly treated domestic wastewater agricultural industrial wastes. Based GWQI, 30% classified very good for drinking purposes. However, over 26% all unsuitable drinking. In terms risk assessment, children rather susceptible cancer adverse effects through As-contaminated than adults. consuming adults up 4.28×10-3that is higher acceptable risk. highest aggregate hazard quotient metal-contaminated 9.54, which means they could suffer effects. an indispensable source freshwater Delta; thus, home treatments are recommended protect public health, in-depth assessment should be conducted.
