Using data from Washington state and empirical methods to control for confounding factors, we estimate the effects of water quality impairments on residential housing prices. We also examine the role of individual water quality parameters such as fecal coliform and dissolved oxygen that are used to judge the attainment of water quality standards. Results indicate that impairments have a negative effect on home values. Using a hedonic model that includes fine-resolution spatial fixed effects, we find that being located adjacent to an impaired waterbody leads to an annualized depreciation of $1942. We find that water quality impairments due to fecal coliform have the largest effects. Given the importance of evaluating the economic benefits of water quality, the use of impairment data to evaluate these benefits on a larger scale could lead to improved allocation of resources to protect the myriad beneficial uses that depend on water quality.

使用来自华盛顿州的数据和经验方法来控制混杂因素，我们估计了水质损害对住宅价格的影响。我们还研究了用于判断是否达到水质标准的粪便大肠菌群和溶解氧等个别水质参数的作用。结果表明，损伤对房屋价值有负面影响。使用包括精细分辨率空间固定效应的享乐模型，我们发现位于受损水体附近会导致年折旧 1942 美元。我们发现粪便大肠菌引起的水质损害影响最大。鉴于评估水质经济效益的重要性，
