Economic evaluation of nitrate in groundwater : A contingent valuation survey in Northwest Florida
Title
Economic evaluation of nitrate in groundwater : A contingent valuation survey in Northwest Florida.
Creator
Carmen J. Lyttle-N'Guessan
Abstract/Description
A double-bounded dichotomous choice contingent valuation survey was administered to 2,000 residents of Franklin and Gulf Counties, Florida, with the objective of documenting any bias as a result of the institutional basis in the hypothetical payment vehicle. The mean willingness to pay (WTP) estimates for state and private payment vehicles are $4.39 and $5.08 per month respectively, significantly different at the 0.15 level. This is evidence of the importance in choosing the institutional...
Show moreA double-bounded dichotomous choice contingent valuation survey was administered to 2,000 residents of Franklin and Gulf Counties, Florida, with the objective of documenting any bias as a result of the institutional basis in the hypothetical payment vehicle. The mean willingness to pay (WTP) estimates for state and private payment vehicles are $4.39 and $5.08 per month respectively, significantly different at the 0.15 level. This is evidence of the importance in choosing the institutional foundation for the payment vehicle. The major determinants of WTP appear to be education, perception of existing water quality and the attitudes of respondents towards the environment. However, WTP responses may vary temporally and spatially with differences in demographics and goods and services valued.

Comparative evaluation of management practices and levels of heavy metals on playgrounds and golf courses in Leon County, Florida
Title
Comparative evaluation of management practices and levels of heavy metals on playgrounds and golf courses in Leon County, Florida.
Creator
Toya Booker
Abstract/Description
In this research various management practices of selected playgrounds and golf courses were evaluated for their impact on heavy metal concentration. The playgrounds and golf courses are in Leon County, Florida. The five selected playgrounds were Levy, Messer, Myers, Tom Brown, and Forestmeadows Parks. The golf courses were Gaither, Killearn North, East, and South, Seminole, and Summerbrooke. Soil samples were collected from each golf course and playground. For the golf courses, five samples...
Show moreIn this research various management practices of selected playgrounds and golf courses were evaluated for their impact on heavy metal concentration. The playgrounds and golf courses are in Leon County, Florida. The five selected playgrounds were Levy, Messer, Myers, Tom Brown, and Forestmeadows Parks. The golf courses were Gaither, Killearn North, East, and South, Seminole, and Summerbrooke. Soil samples were collected from each golf course and playground. For the golf courses, five samples were taken from each green and tee for each hole. For the parks, three sets of samples were taken fiom the playfield, the surrounding grassy areas, and from another part of the park at least 150 feet away to be used as a control. The soil samples were analyzed for Nitrates, pH, Aluminum, Copper, Lead, Zinc, and Arsenic concentrations. Dry matter and pH were also determined. The Nitrate content was done at the Agricultural Research Station in Tifton, GA. Micro-Macro Laboratories in Athens, GA performed the metal analyses using the Atomic Absorption Spectroscopy. Our results indicate that there were differences among greens and tees for Nitrates, pH, and metal concentrations on golf courses. The Nitrate content for tees at Gaither, Killearn (South), Killeam (East) were higher than the greens at other golf courses, but at Killeam (North) the greens Nitrate content was higher than the tees. For Levy Park, the Nitrate content of the actual play area was higher than the outside, but not significant compared to the control. In Messer Park the outside Nitrate content was higher than the actual, but not significant compared to the control. In Meyers Park the actual Nitrate content was higher than the outside, but not significant compared to the control. In Tom Brown Park the outside and actual Nitrate content was higher than the control. In F orestmeadows park the outside and actual was higher than the control. There were also significant differences shown within each playground for heavy metals. The aluminum values on the outside and actual areas of each playground were significantly different from the control. Copper values varied among playgrounds and golf courses. At Levy and Tom Brown Park, the outside area was higher than the control. At Forestmeadows Park, the outside and actual were higher than the control. Zinc values also Varied among playgrounds and golf courses. At Levy, Messer, and Meyers parks the actual and outside were higher than the control. At Tom Brown Park, the outside and actual were similar, but they were higher than the control. At Forestmeadows Park, the outside and actual were different from the control. Management practices for each golf course were found to be unique for each golf course and playground
