LAS contamination was correlated with population density and ammonia nitrogen. Environmental fate was subject to suspended solids rather than biodegradation. Longer alkyl chain lengths were more absorbed to large suspended solids (>11 μm). LAS concentration at 3 sub-basins was over predicted no effect concentrations. Environmental risk areas and susceptible areas due to LAS were spatially identified.
