This research was to determine the burden of water pollution in the Citanduy tributaries. Sampling was carried out by purposive sampling using the storet method. Sampling was done with a distance of each point as far as 1 km for 3 sampling points, namely Parakanyasag Village coordinate 7017 '46.4 "S 108 ° 13'04.3" E with areas dominated by rice fields without industry. The second point in the Village of Cicariuk at coordinates 7 ° 18'08.9 "S 108 ° 13'07.4" E, this point is the central point of the batik industry in Cigeureung. The third point is in Gg.
