美国各地的大小系统，无论人口和地理位置如何，都容易受到污染。今天，与过去不同，我们对如何保护地下水免受污染有了更好的理解。在公众教育的帮助下，过去将地下水污染置于危险境地的做法不再被允许。现行法规通过井口保护和交叉连接控制等项目保护地下水的未来。当安全饮用水法规似乎势不可挡时，人们应该记得，它们也可能成为自身水系统污染的受害者。有许多机构有资金帮助需要紧急财政援助的受污染农村供水系统。发现自己的系统受到污染的水务运营商可以记住，在使用可用资源时，确实存在可行的解决方案。本文包括一个拖车村移动家庭公园的案例研究，该公园的水井被四氯乙烯（PCE）污染。

Large and small systems across the United States, regardless of population and geographical location, are susceptible to contamination. Today, unlike the past, we have a better understanding of how to protect our groundwater against contamination. With the help of public education, past practices that put groundwater contamination at risk are no longer allowed. Current regulations are protecting the future of our groundwater with programs such as wellhead protection and cross connection control. When safe drinking water regulations seem overwhelming, one should recall that they too could be the victim of contamination in their own water system. There are many agencies with the funding to help contaminated rural water systems in need of emergency financial assistance. Water operators that find their system contaminated can remember that workable solutions do exist, when one uses the available resources. This paper includes a case study of Trailer Village Mobile Home Park whose wells were contaminated with tetrachloroethylene (PCE).
