Poor water quality has been reported along with a variety of negative health outcomes in the Saharawi refugee camps in Algeria. We assessed the concentration of elements in drinking water and urine in refugee women and children. Twenty-four samples of distributed public drinking water were collected, along with urine samples from 77 women and 296 children. Using inductively coupledplasmamassspectrometry,weanalyzedwaterandurinefor31and10elements,respectively. In addition, the water samples were analyzed for ﬁve anions by ion-exchange chromatography. Data were described according to two areas: zone 1 with puriﬁed water and water with naturally better quality, and zone 2 with only partially puriﬁed water. Most elements in drinking water had signiﬁcantly higher concentration in zone 2 compared with zone 1. Sodium, chloride, nitrite, and nitrate were the parameters that exceeded the WHO Guidelines for Drinking Water Quality. Among both women and children, urinary concentration of vanadium, arsenic, selenium, lead, iodine, and uranium exceeded reference values, and most of the elements were signiﬁcantly higher in zone 2 compared to zone 1. Even though water puriﬁcation in the Saharawi refugee camps has increased during the last years, some elements are still exceeding the WHO guidelines for drinking water quality. Moreover, urinary exposure of some elements exceeded reference values from the literature. Further effort should be made to improve the water quality among the Saharawi refugees.
