Groundwater contamination at a landfill: a case study of coastal park landfill, Cape Town
Published 2023“…This study aimed to determine the fluxes in groundwater quality at the Coastal Park landfill in Cape Town, South Africa, and to analyse how groundwater quality changes with local rainfall. Changes in borehole water levels, pH, conductivity, dissolved oxygen, ammonia, nitrate and phosphate were analysed over consecutive weeks of seasonal rainfall from boreholes that were upstream and downstream of two large landfill cells; one being lined and the other unlined. …”
