The surficial aquifer is the primary source of freshwater for the heavily developed coastal area in eastern Palm Beach County, Florida. Well fields are generally located in a discontinuous zone of higher secondary permeability, the northernmost extension of the Biscayne aquifer in the surficial aquifer, that extends from the Juno Beach area south to Broward County and varies in width .

    To address concerns about the effects of water-resource management practices and rising sea level on saltwater intrusion, the U.S. Geological Survey in cooperation with the Broward County Environmental Planning and Community Resilience Division, initiated a study to examine causes of saltwater intrusion and predict the effects of future.   One of the greatest environmental dangers in South Florida lurks under our feet. When it comes to disasters, saltwater intrusion isn't as sexy as ocean seas swallowing up Florida's coastline or as Author: Susan Stabley.

    Best Practices for Prevention of Saltwater Intrusion Author: Ministry of Forest Subject: Saltwater intrusion occurs when saline (salty) water is drawn into a freshwater aquifer. Saltwater intrusion can affect one well, or multiple wells in an aquifer, making the . Second of three parts. Saltwater is creeping farther inland into the soil and surface waters of North Carolina’s coastal plain. This “saltwater intrusion,” as scientists call it, has an ability to transform freshwater landscapes long before they’re permanently drowned by the rising sea.

Of the counties in southeastern Florida, Broward County has experienced some of the most severe effects of saltwater intrusion into the surficial Biscayne aquifer because, beforemost public water-supply well fields in the county were constructed near the principal early population centers located less than 5 miles from the Atlantic Ocean.

To obtain fresh water, the city has been forced to obtain half of its water from Broward County’s western well fields and is currently hoping to. Saltwater intrusion in southern Broward County (Dania, Hollywood, and Hallandale) is different than that observed in the central and northern parts of the county (fig.

The heads in the area are lower than in any other part of Broward County, with the exception of local areas near well fields such as the Five Ash/Prospect well field.

Saltwater has intruded into many of the coastal aquifers of the United States, Mexico, and Canada, but the extent of saltwater intrusion varies widely among localities and hydrogeologic settings. In many instances, the area contaminated by saltwater is limited to small parts of an aquifer and to specific wells and has had little or no effect on overall groundwater Cited by: increased the potential for saltwater intrusion into the aquifer in coastal areas of west-central Florida, Ground-water withdrawals are likely to increase because of the expected population growth, especially in coastal areas.

To gain a better understanding of the potential for and mechanisms of saltwater intrusion,Cited by: 4. Unified Sea Level Rise Projection (37 pp, K, About PDF) Exit Southeast Florida, with a large population located at low elevation, is among the most vulnerable regions of the country to climate change.

The region is comprised of four counties (Monroe, Miami-Dade, Broward, and Palm Beach) that share similar geographic traits and coastal vulnerabilities to sea level rise.

Coastal groundwater flow investigations at the Cutler site of the Biscayne Bay south of Miami, Florida, gave rise to the dominating concept of density-driven flow of seawater into coastal aquifers indicated as a saltwater wedge. Within that wedge, convection-type return flow of seawater and a dispersion zone were concluded to be the cause of the Biscayne Cited by: 3.

In the early half of the 20th century, Miami-Dade County witnessed the closure of three public water supply well fields due to saltwater intrusion – two of them shut down permanently.

A consequence of climate change is the intrusion of saltwater into freshwater systems. Coastal Louisiana is currently experiencing higher than expected salinities in traditionally freshwater marshes and waterways.

Studies of the effects of saltwater intrusion on resident animals are usually limited to documenting community changes. Recent land-based seismic reflection surveys at Ft. George Island, Florida () show a large solution feature in the northeastern part of the island (Odum and others, ).Reflectors within the upper Hawthorn Group show evidence of downwarping and displacement (approximately 65 feet of vertical subsidence) as the interbedded carbonates, clay, and sand strata deform plastically.

• The completion of key Everglades restoration will deliver more freshwater to the Everglades. These projects are countermeasures to the effects of saltwater intrusion on South Florida's drinking water supply.

This risk assessment framework is used to map risk of saltwater intrusion in the coastal bedrock aquifers of the Gulf Islands, BC. The mapping is carried out in ArcGIS Details concerning how each variable was mapped and the intermediate results are provided in the following by: Saltwater intrusion is the movement of saline water into freshwater aquifers, which can lead to groundwater quality degradation, including drinking water sources, and other consequences.

Saltwater intrusion can naturally occur in coastal aquifers, owing to the hydraulic connection between groundwater and e saline water has a higher mineral content than.

Broward County, Florida January 5, I Project Background Most of Broward County’s shoreline are in a state of chronic erosion. The State of Florida has estimated that 21 of the 24 miles of Broward’s beaches are critically eroded, and in some areas there is little beach left at high tide.
