AWWA A100-97

This standard covers the minimum requirements for vertical water supply wells. The purpose of this standard is to provide the minimum requirements for water wells, including geologic/hydrologic conditions and water quality and well construction. This standard can be referenced in specifications for constructing water wells and can be used as a guide for vertical water supply wells. The stipulations of this standard apply when this document has been referenced and then only to water wells used in water supply service applications. Major topics covered are: investigation of geologic/hydrologic conditions and groundwater quality; material requirements; well casing; well screens; gravel pack; well construction; well development; well disinfection; decommissioning of test holes, partially completed wells, and abandoned wells; performance testing; and water quality testing. Appendices cover: gravel pack installation methods; grouting and sealing, methods of placement; plumbness and alignment, procedure for testing; well development; water sampling, suggested methods; factors influencing the duration of pumping test; decommissioning of test holes, partially completed wells, and abandoned completed wells; geophysical borehole logs; types of wells; and, collapse strength of well casing.
