Monitoring Well Rehabilitation Using the Surge Block Technique

Source

Monitoring wells at a site where the ground water is contaminated with organic solvents were rehabilitated using the surge block method. Several different methods were reviewed for their ability to remove sediments from the well as well as from the soils adjacent to the outside of the well screen. The surge block technique was selected as a method that would accomplish both objectives. The surge block technique is described and is compared with other well rehabilitaton methods. The results of presurging and postsurging groundwater quality from selected monitoring wells are presented. The surge block method was shown to increase the hydraulic capacity of the wells and removed sediment from the bottoms of the wells. Continued monitoring of the wells will indicate whether these benefits are short term or are related to accumulations of sediments at the bottoms of the wells.
