title: Organic contaminates in water.
abstract: The carbon adsorption method was used for separating organic matter from large samples of drainage, river and tap water. The carbon chloroform extract (CCE) was separated into different solubility fractions and the neutral fraction was separated into aliphatic, aromatic and oxy-compounds using column chromatography. The aromatic fraction was subjected to TLC, IR and UV analysis. The pesticide endrin was present in both river and tap water at concentrations of 0.7 and 1.5 ppb, respectively.
