联邦政府通过几项监管计划解决了地下水污染问题，包括《安全饮用水法案》、《井口保护计划》、《地表水处理规则》和《地下水消毒规则》。为了使这些规定有效，公用事业公司有利于对地下水源的水文地质有基本的了解；也就是说，地表水如何补给含水层并流向收集设备，如井、泉水或渗透廊道。不幸的是，我们对许多地下水系统的流动特征知之甚少；尤其是小型系统，它们不具备对补给和地下水流动进行广泛水文调查所需的资源。 操作员的温度监测可能有助于提高对地下水系统的了解。本文旨在证明长期地表水和地下水温度数据收集对井口保护、地下水消毒规则评估和地下水消毒评估的益处。

The federal government has addressed issues of groundwater contamination through several regulatory programs including the Safe Drinking Water Act, the Wellhead Protection Program, the Surface Water Treatment Rule, and the Ground Water Disinfection Rule. In order for these regulations to be effective, it is beneficial for utilities to have an elemental understanding of the hydrogeology of the groundwater source; that is, how surface water recharges the aquifer and flows to a collection device such as a well, spring, or infiltration gallery. Unfortunately, little may actually be known concerning the flow characteristics for many of our groundwater systems; especially small systems that do not have the resources necessary to make extensive hydrologic investigations of recharge and groundwater flow. Temperature monitoring by operators may help to improve the understanding of the groundwater system. The purpose of this paper is to demonstrate the benefits of long term surface water and groundwater temperature data collection for wellhead protection, Ground Water Disinfection Rule evaluations, and groundwater disinfection evaluations.
