Increased development of the Castle Hayne (carbonate) aquifer has occurred in Onslow County as a result of reduced withdrawals from the Cretaceous aquifers. Increased groundwater withdrawals from these aquifers and their close proximity to the Atlantic Ocean increase the potential for movement of saltwater into the aquifers. The most recent comprehensive groundwater study conducted in Onslow County was completed in 1989 (Lyke and Winner, 1990); an up-to-date groundwater flow model is needed to assess the long-term effects of groundwater withdrawals on groundwater levels and saltwater movement in the area.
