Abstract:

The paper reports on a study to assess the water resource availability of two artesian aquifers (the mid-Hawthorn and lower Hawthorn) in Cape Coral, Florida. The impacts of future withdrawal scenarios were derived using the P. E. Trescott, G. F. Pinder and S. F. Larson two-dimensional finite difference flow model. The results of the study indicate that the mid-Hawthorn aquifer is currently being overstressed with 80 percent of the water withdrawn coming from leakance from other aquifers. Continued excessive pumpage of the mid-Hawthorn will result in periodical failure of municipal wellfields and/or irreversible deterioration of the water quality.
