Description
Summary:This study examined the water quality of Saguling Reservoir as potential raw water for Bandung metropolitan area. Determination of water quality in this study consisted of trophic status determination based on total phosphorus, total nitrogen (ammonia and nitrate), and water clarity. Data were obtained 4 times a year for 16 years (1999-2013). We determined the overall water quality status by comparing data with criteria specified in Ministerial Regulation (Permen) of the Environment Number 28 of 2009 on the Water Pollution Load Capacity of Lakes or Reservoirs. Data from 11 stations were analyzed, which indicated a hypertrophic state with very high pollution. Nanjung Post (upstream of the reservoir) had the highest levels of total P, total N, and chlorophyll a compared with the Muara Ciminyak Post and Muara Intake Post (the middle and downstream regions of the reservoir). Seasonal changes had no effect on the trophic status, regardless of dry, normal, or wet conditions.
