摘　　要：为了查明地方病区地下水的形成条件、赋存规律、补径排特征和地下水化学特征需要建造监测井,采取地下水样品。本文就监测井的建造材料和成井工艺及取样技术做出论述,提出在地方病区最好选用PVC-U井管、携砾滤水管,建造分层止水、分层取样的监测井,辅以地下水定深取样和双帕克分层采样系统,采集有代表性的地下水样品。For the purpose of detecting the formation condition, occurrence regularity and chemical characteristics as well as the recharge, runoff and drainage characteristics of groundwater, the building of monitoring well for sample collection is necessary. This paper deals with construction materials, well completion technology and sampling techniques, and presents the optimization of PVC-U well pipe and gravel filter as well as the differential shut of water and stratified sampling of monitoring well in the endemic disease area. Typical groundwater samples are collected through the depth preset sampling and double-packer systems.
