Well casing and well screen:<\/p>\n

Today, most of the monitoring wells will be constructed of polyvinyl chloride (PVC) or stainless steel, followed by low carbon or galvanized steel. Other materials (ABS, PE, PP) are rarely suitable for the construction of environmental monitoring wells, or the size of production is usually not suitable for the construction of monitoring wells.<\/p>\n

In selecting the appropriate well material, the installation of a monitoring well requires consideration of potential sources of chemical interference. In general, the interference to groundwater quality caused by wellbore and well screen includes adsorption, desorption and leaching, corrosion and chemical degradation of well material, production residue resulted from the production, storage and processing of well material. In the installation process, there is also potential interferences as result of adhesion of plastic and plastic materials, heat welding.<\/p>\n

The diameter of the well is mainly dependent on the purpose of the well construction, and other factors may include the following:<\/p>\n
