The textile industrial development along the road of Rancaekek-Cicalengka are the contributors of pollutants in the river because for almost the textile indutries along the road of Rancaekek-Cicalengka have to dispose of their waste products to Cimande River and Cikijing River that will lead to Citarik River as Citarum upstream. Then, the polluted river water are used by people as a growing medium of food crops such as kangkung. Hence, the objectives of this research were to determine the concentration of heavy metals contained in kangkung and their relation with the concentration of heavy metals in the water as a growing medium. The concentration of heavy metals were analyzed by Inductively Coupled Plasma (ICP). The heavy metal which measured include Cd, Cu, Cr, Pb, Mn, and Zn. Samples preparation for water were acid digestion and for kangkung samples were acid extraction based on Standard Method EPA 200.2. The results of this research indicate that the water has been polluted by Cr, Cu, and Zn with a concentration of each metal measurable range between 0.0767 mg/l to 0.4587 mg/l (Cr); 0,0617 mg/l to 0.135 mg/l (Cu); 0.1245 mg/l to 0.6972 mg/l (Zn). While, kangkung become unfit for consumption because it has been contaminated by Cd and Cr in every area, Cu in D area (Linggar Village), Pb in A area (Linggar Village), and Mn in B areaa (Linggar Village) and D area (jelegong Village) which concentrations ranged from 0,53 mg/kg to 9.34 mg/kg (Cd); 10.76 mg/kg to 248.357 mg/kg (Cr); 8.5 mg/kg to 109.43 mg/kg (Cu); 105.58 mg/kg to 1,459.75 mg/kg (Mn); and 0.28 m/kg to 18.2 mg/kg (Pb).
