Restoration Project to Enhance Weil Field Wetlands

摘要

Due to a hydraulic connection between the surficial and Upper Floridan aquifers in the Tampa Bay area, creative management techniques are becoming extremely important for minimizing ground-water pumping impacts to wetland features. The Section 21 Well Field, currently operated by Tampa Bay Water in Florida, was first developed by the City of St. Petersburg in 1960. It provided the city with potable water supplies for several decades. The field is now part of a regional water supply source for the Tampa Bay area. The well field property is characterized by lakes and cypress wetlands. Pumping from the six wells at rates of up to 20 mgd has contributed to lowered water levels and depressed hydrologic conditions in lakes and wetlands on the well field property. During the mid 1990's, LBG performed an evaluation of hydrologic conditions in and around the field and concluded that in addition to the drawdown effects from pumpage, there were additional causes for hydrologic stress resulting from drought, drainage, and development.
