尽管地下水源的运行要求远低于地表水 水源、水系统运营商和管理者应制定计划 定期评估每个地下水源。收集和评估相关信息 信息将使水系统决策者能够检测到运行环境的变化 特性和水质。井口保护活动的定期审查 zone可以提醒系统管理员将来可能影响其源的更改。 了解可能影响地下水源的因素有助于决策 在问题或潜在问题成为重大问题之前，缓解或解决这些问题 紧急事件。了解每个来源的运营成本也会增加有价值的信息 在考虑对资源和可用替代品的持续或未来投资时。

Even though groundwater sources are much less demanding to operate than surface water sources, water system operators and managers should have a program in place to routinely evaluate each of their groundwater sources. Gathering and evaluating pertinent information will allow water system decision makers to detect changes in operational characteristics and water quality. Periodic review of activities in the wellhead protection zone can alert system managers for changes that may affect their source in the future. Knowing the factors that may affect a groundwater source allows decisions to be made to either mitigate or resolve problems, or potential problems, before they become major emergencies. Knowing the operating costs of each source also adds valuable information when considering on-going or future investments in the source and available alternatives.
