dc.description.abstract	Arsenic is a non-metallic constituent, resent naturally in groundwater due to some minerals and rocks. Arsenic is not geologically uncommon and occurs in natural water as arsenate and arsenite. Additionally, arsenic may occur from industrial discharges or insecticide application. World Health Organization (WHO) and Pakistan Standard Quality Control Authority have recommended a permissible limit of 10 pb for arsenic in drinking water. Arsenic at lower concentrations can e determined in water y using high tech instruments like the Atomic Absorption Spectrometer (hydride generation). Because arsenic concentration at low limits of 1 pb cannot be determined easily with simple spectrophotometric technique, the spectrophoto metric technique using silver diethyldithiocarbamate was modified to achieve better results, up to the extent of 1 pb arsenic concentration	en_US
