NGWA develops industry best suggested practice for water well system professionals
The National Ground Water Assn. (NGWA) has developed an industry best suggested practice (BSP) for water well system professionals to use regarding the emergency disinfection of flooded residential water wells.

Steps involved in emergency well disinfection, as outlined in the BSP, include:
Residential Water Well Disinfection Following a Flood was developed by a work group of NGWA member professionals drawing from extensive experience and referenced research. Available as a PDF, it can be downloaded. While free to NGWA members, there is a nominal charge to nonmembers.
