This is often aggravated by insufficient renewal to the freshwater aquifer, which often occurs in times of drought (Ryan, 2008). Unfortunately saltwater intrusion can't be stopped, but the rate at which it occurs needs to be slowed. A management plan for saltwater intrusion needs to involve a number of different approaches. In areas where salinization is caused by storm surge, it is thought that coastal barriers could be built in order to prevent or slow the storm surge. Where saltwater has been introduced because of storm surge, some manner of opening the barriers would be necessary in order to allow the saltwater to be washed out of the freshwater system. This would involve a substantial engineering requirement. Opponents to this approach argue that engineering a natural process would end up doing more harm because of the impact the structures would have on natural systems. Conversely, the loss of wetland habitat influences many things including tourism in coastal area (Ryan, 2008).

In areas that are burdened with saltwater intrusion because of over pumping of the overlying freshwater aquifers, the management solution should involve cooperation from multiple levels. The main dilemma of pumping groundwater at a pace that is not sustainable must be looked at. On the other hand, the impact of the saltwater intrusion must be calculated. This is usually done by approximating how many wells have previously been impacted and what the projection is for potential impacts given the current pumping rates. It is thought that the cost of reducing groundwater withdrawals is more than the cost of re-establishing...
