%X Monitoring of water quality pollution can be conducted in various ways,  including using bioindicator such as gastropods. The aim of this research was to  determine the water quality of Gajah Wong river based on the diversity of gastropods.  The study was conducted in September- Oktober 2012 at 3 stations of the upstream  part of of Gajah Wong watershed. Station 1 is located at Sardonoharjo, station 2 at  Harjobinangun, and station 3 at Hargobinangun. The method used in this research  was the technique of kicking and jabbing with 3 replications. The water quality of  Gajah Wong river was calculated by taking account gastropod diversity using the  Shannon-Wiener diversity index. The difference of parameters tested was analyzed  using one way ANOVA, and the relationship between environmental parameters with  the number of individuals gastropod was tested using correlation-regression analysis.  The results found 12 species of gastropods with the lowest number of total species at  station 2 (261 individuals), while the highest number of total species at station 1 (324  individuals). The ANOVA test showed significant differences of the number of  gastropods in the researched stations. According to the Shannon-Wiener diversity  index, Gajah Wong river was slightly contaminated with the lowest diversity index at  station 1 of 2,43 and the highest index value at station 3 with a value of 2,90. The  correlation coefficient test in the parameters tested showed a positive correlation but  no significant relation between environmental factors and the number of gastropods.
