N2 - Agricultural land dominates Brantas River watershed, so it is potentially polluted due to excessive use of agrochemicals. This study aims to calculate the carrying capacity of atrazine and map its distribution from Brantas to Porong River. Carrying capacity is calculated using mass balance approach based on the Decree of the Minister of Environment Number 110 of 2003. Mapping is done using IDW interpolation on ArcGIS Pro. There are 19 sampling points in the upstream-middle part and 21 points in the middle-downstream part. All sample points had atrazine levels exceeding the quality standard of 0.002 mg.L−1. The carrying capacity was calculated to be −368,820.16 kg.day−1 in the upstream-middle part and −63,382.24 kg.day−1 in the middle-downstream part due to the APL being greater than MPL. Based on the mapping results, atrazine concentrations in the upstream-middle section have the highest range in Segment 1 (4.0–11.6 mg.L−1) and in the middle-downstream section in Segment A (11.4–17.6 mg.L−1).
