地下水环境监测井评估体系构建研究

为科学开展监测井评估，选择井口保护装置/井口状况、井管内径、上部井管保存状态、是否串层、井结构保存状态、井的连通性6个指标，建立监测井维护评估和监测井功能评估方法，构建地下水环境监测井评估体系。监测井维护评估最终的评估结果分为无需修复、修复和报废，用于指导地下水环境监测井维护管理，使之满足长期监测要求；监测井功能评估最终的评估结果分为监测功能良好、监测功能一般和不具有监测功能，用于判定监测井的监测功能状况，是否可以执行当前监测任务。研究可为健全地下水环境监测网络，规范开展地下水环境监测提供技术支撑。

Study on the Construction of Groundwater Environment Monitoring Well Evaluation

In order to scientifically carry out monitoring well evaluation, this paper selected six indicators: wellhead protection device / wellhead condition, inner diameter of well pipe, preservation state of upper well pipe, whether to string layers, well structure preservation status and well connectivity, established the maintenance evaluation method and the function evaluation method of monitoring well. The final evaluation result of maintenance assessment is that there is no need to repair, repair and scrap, which is used to guide the maintenance and management of groundwater environment monitoring wells to meet the long term monitoring requirements. The final evaluation result of function evaluation is that the monitoring function is good, general and does not have the monitoring function. It is used to determine whether it can perform the current monitoring task. The research can provide technical support for improving the groundwater environment monitoring network and standardizing the groundwater environment monitoring.
