Drinking water quality is considered to be of vital importance for all human beings and animals but its significance is much more heightened when consumer is a teenager. In view of foregone, groundwater quality assessment of 150 public schools situated in flooded areas of Southern Punjab, Pakistan, was carried out. Analysis results revealed that 49 and 37 % water samples are contaminated with coliform and faecal coliforms, respectively. On the other hand chemicals constituents in samples, including calcium (43 %), magnesium (11 %), potassium (37 %), sodium (31 %), sulphate (39 %), hardness (31 %), total dissolved solids (TDS) (35 %) and chloride (15 %) were higher than World Health Organization (WHO) limits. The situation is more serious as fluoride, iron and arsenic were also found in high concentration in 15, 60 and 58 % samples, respectively. Health risk assessment data indicated that mean chronic daily intake (CDI) values for children and adults were 0.592 and 0.537 μg/kg/day for arsenic and 0.012 and 0.011 μg/kg/day for iron, respectively. Calculated arsenic health risk index (HRI) > 1 for 88 and 58 % water samples for children and adults respectively, which highlights possible health risks associated with intake of contaminated water.

En vista de lo anterior, se llevó a cabo una evaluación de la calidad de las aguas subterráneas de 150 escuelas públicas ubicadas en áreas inundadas del sur de Punjab, Pakistán. Los resultados del análisis revelaron que 49 y 37% de las muestras de agua están contaminadas con coliformes y coliformes fecales, respectivamente. Por otro lado, los componentes químicos en las muestras que incluyen calcio (43 %), magnesio (11 %), potasio (37 %), sodio (31 %), sulfato (39 %), dureza (31 %), sólidos disueltos totales (TDS) (35 %) y cloruro (15 %)en 43, 11, 37, 31, 39, 31, 35 y 15% de las muestras fueron mayores que los límites de la Organización Mundial de la Salud (OMS). La situación es más ya que el fluoruro, el hierro y el arsénico también se encon
