Rapid Creek is a tropical mangrove lined tidal creek within a largely urban setting of Darwin in the Northern Territory. Increasing development in the catchment has led to a significant number of diffuse pollutant sources to the creek, mainly from urban stormwater discharge to the creek delivering elevated nutrient, hydrocarbon and metal pollutant loads to the coastal creek system. The primary objective of the study was to assess whether the surficial sediments of the creek's mangroves are polluted with metals, nutrients and hydrocarbons. Sediments were examined along the estuarine reach of the creek along three elevation
transects extending from the landward to seaward edge. Each transect comprised 3 sample sites represented by replicate samples.,
