Salt Water Intrusion in the Tampa Bay Area By: Marko Steiger Personal Background/Introduction Areas Affected by Salt Water Intrusion Water a limited resource The limited potable drinking water supply could be one of the most serious problems to a life support system. Drinking water standards established by the US Environmental Protection Agency (USEPA) in 1962 require that drinking water contain no more than 500 mg/L of total suspended solids (TSS), a common measure of salinity. Seawater contains approximately 30,000 mg/L of TSS, 60 times higher than the USEPA standard for drinking water. Therefore, it is evident that even a small amount of seawater can cause problems when mixed with freshwater reservoirs. Also, salinity in irrigation water can be detrimental to agriculture, reducing yields and killing crops. Ghyben-Herzberg equation Salt water intrusion is the migration of saltwater into freshwater aquifers under the influence of groundwater development. The Freshwater-Saltwater interface can be expressed by the Ghyben-Herzberg equation. It shows that the change of seawater thickness in the aquifer depends on the change of fresh-water thickness. However, the increase of saltwater thickness has been amplified by as many as 33 times, depending on the specific weight of
