Perspectives of low cost arsenic remediation of drinking water in Pakistan and other countries

---

Abstract.
Arsenic concentrations above acceptable standards for drinkingwater have been detected in many countries
and this should therefore is a global issue. The presence of arsenic in subsurface aquifers and drinking
water systems is a potentially serious human health hazard. The current population growth in Pakistan
and other developing countries will have direct bearing on the water sector for meeting the domestic,
industrial and agricultural needs. Pakistan is about to exhaust its available water resources and is on the
verge of becoming a water deficit country.Water pollution is a serious menace in Pakistan, as almost 70%
of its surface waters as well as its groundwater reserves have contaminated by biological, organic and
inorganic pollutants. In some areas of Pakistan, a number of shallowaquifers and tubewells are contaminated
with arsenic at levels which are above the recommended USEPA arsenic level of 10 ppb (10 ugL−1).
Adverse health effects including human mortality from drinking water are well documented and can be
attributed to arsenic contamination. The present paper reviews appropriate and lowcost methods for the
elimination of arsenic from drinking waters. It is recommended that a combination of low cost chemical
treatment like ion exchange, filtration and adsorption along with bioremediation may be useful option
for arsenic removal from drinking water.
