很少有研究探讨地下水质量对住宅物业价值的影响。使用一个独特的数据集的井测试，我们联系住宅真实的房地产交易，以家庭特定的污染，并在湖县，佛罗里达，在那里的污染问题主要涉及到农业径流的销售进行享乐分析。我们发现，最近的测试和地下水污染对应于房屋价值的2- 6%的贬值，随着时间的推移，这种影响会逐渐减少。关注氮基污染，我们发现，价格下降主要是当浓度超过监管健康标准时，这意味着在两倍于标准的水平上贬值高达15%。
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.
