Impacts of Ground Water Contamination on Property Values: Agricultural Run-off and Private Wells
نویسندگان
چکیده
Few studies have examined the impacts of ground water quality on residential property values. Using a unique data set of well tests, we link residential real estate transactions to home-specific contamination and conduct a hedonic analysis of sales in Lake County, Florida, where pollution concerns relate primarily to agricultural run-off. We find that recent testing and contamination of ground water there correspond to a 2–6 percent depreciation in home values, an effect that diminishes over time. Focusing on nitrogen-based contamination, we find that prices decline mainly when concentrations exceed the regulatory health standard, suggesting as much as a 15 percent depreciation at levels twice the standard.

National Water-Quality Assessment (NAWQA) Program collected or compiled data on ground water from 1926 private wells in rural areas across the United States from 1986 to 1999. These private wells, also called domestic wells, are owned and operated by the homeowners and provide water for household uses, including drinking, food preparation, watering lawns and gardens, bathing, and washing clothe...
متن کاملGroundwater quality assessment using the water quality pollution indices in Toyserkan Plain
Background: Iran is located within the dry and semi dry regions, thus almost 90% of the required water is secured via the use of groundwater. Owing to the increasing pollution of water resources, this study was performed to evaluate water quality pollution indices for heavy metals (As, Zn, Pb and Cu) contamination monitoring in Toyserkan Plain during spring and summer in 2012. Methods: A tot...
متن کاملNitrate distributions and source identification in the Abbotsford-Sumas Aquifer, northwestern Washington State.
The Abbotsford-Sumas Aquifer is a shallow, predominantly unconfined aquifer that spans regions in southwestern British Columbia, Canada and northwestern Washington, USA. The aquifer is prone to nitrate contamination because of extensive regional agricultural practices. A 22-month ground water nitrate assessment was performed in a 10-km2 study area adjacent to the international boundary in north...
