(WESTERVILLE, OH — February 19, 2013) The National Ground Water Association has developed an industry best suggested practice (BSP) for water well system professionals to use regarding the emergency disinfection of flooded residential water wells.
Residential Water Well Disinfection Following a Flood:
Variables noted in the BSP that can influence proper well disinfection procedures include, but are not limited to, local geologic conditions and a well’s design, dimensions, and condition.
NGWA’s recommendations address two classifications of private water wells: (1) wells that are not generally at risk based on their construction and maintenance, and (2) wells that are at risk due to construction deficiencies and/or lack of maintenance that compromise the integrity of the well.
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 at www.NGWA.org/Bookstore (type "flood" into the keyword search box). While free to NGWA members, there is a nominal charge to nonmembers.
NGWA, a nonprofit organization composed of U.S. and international groundwater professionals — contractors, equipment manufacturers, suppliers, scientists, and engineers — is dedicated to advancing groundwater knowledge. NGWA’s vision is to be the leading groundwater association that advocates the responsible development, management, and use of water.
