Estimation of submarine groundwater discharge in Plover Cove, Tolo Harbour, Hong Kong by 222Rn

Abstract Algal blooms in Tolo Harbour, Hong Kong have received much attention and submarine groundwater discharge is speculated to be a significant pathway carrying nutrients into the constricted estuary. Plover Cove, a small cove in the Harbour, was selected for SGD analysis using 222Rn budget. The volumetric SGD rates are estimated to be about 8000 m3/day for neap tide and about 17,000 m3/day for spring tide. Result of nutrient analysis of the porewater indicates that the nutrient loading through this pathway is speculated to be crucial for eutrophication in Tolo Harbour. Current practice for the management of algal blooms in Hong Kong, in which nutrient loading through SGD was ignored, has to be reviewed and the control measures of groundwater contamination are obviously required.
