Ground Water Vulnerability Assessment: Contamination Potential Under Conditions of Uncertainty
for classification as "high water recharge land" must meet the following criteria established by the commission:
The parcel must be located in the high recharge areas designated on maps supplied by each of the five WMDs.
The high recharge area of the parcel must be at least 10 acres.
The land use must be vacant or single-family residential.
The parcel must not be receiving any other special assessment, such as Greenbelt classification for agricultural lands.
Two bills related to the implementation of the Bluebelt program are being considered by the 1993 Florida legislation.
THE SAN JOAQUIN VALLEY
Pesticide contamination of ground water resources is a serious concern in California's San Joaquin Valley (SJV). Contamination of the area's aquifer system has resulted from a combination of natural geologic conditions and human intervention in exploiting the SJV's natural resources. The SJV is now the principal target of extensive ground water monitoring activities in the state.
Agriculture has imposed major environmental stresses on the SJV. Natural wetlands have been drained and the land reclaimed for agricultural purposes. Canal systems convey water from the northern, wetter parts of the state to the south, where it is used for irrigation and reclamation projects. Tens of thousands of wells tap the sole source aquifer system to supply water for domestic consumption and crop irrigation. Cities and towns have sprouted throughout the region and supply the human resources necessary to support the agriculture and petroleum industries.
Agriculture is the principal industry in California. With 1989 cash receipts of more than $17.6 billion, the state's agricultural industry produced more than 50 percent of the nation's fruits, nuts, and vegetables on 3 percent of the nation's farmland. California agriculture is a diversified industry that produces more than 250 crop and livestock commodities, most of which can be found in the SJV.
Fresno County, the largest agricultural county in the state, is situated in the heart of the SJV, between the San Joaquin River to the north and the Kings River on the south. Grapes, stone fruits, and citrus are important commodities in the region. These and many other commodities important to the region are susceptible to nematodes which thrive in the county's coarse-textured soils.
