NGWA’s eight-year effort to establish the standard expectations for water well system professionals to meet culminated in ANSI’s approval of ANSI/NGWA-01-14, a water well construction standard.

“This is a very good day for our industry. I trust this standard will help us all design and build better products and services for our customers,” said Todd E. Hunter, CWD/PI, a member of NGWA’s Standards Development Oversight Committee and an NGWA Board officer. “I thank everyone involved for the countless hours spent putting this together.”

Thom M. Hanna, RPG, also a member of NGWA’s Standards Development Oversight Committee said, “There is more guidance in some places than others, but there are a lot of areas where there is no guidance.” These areas are where NGWA’s standard offers guidance on properly designed and constructed wells by providing minimum criteria in areas including the following:

  • Well site selection
  • Casing and casing installation
  • Well screens, filter pack and formation stabilizer
  • Grouting
  • Plumbness and alignment
  • Well development
  • Testing for performance
  • Data recording
  • Disinfection with chlorine
  • Water sampling and analysis
  • Permanent well and test-hole decommissioning

The NGWA had to meet ANSI’s standard development process and wait through a 15-day appeal period to receive the approval. Upon final approval, ANSI/NGWA-01-14 will be NGWA’s first-ever third-party-sanctioned standard and will set a baseline of expectations for residential, agricultural, monitoring, industrial and public supply water wells.

Stated goals of the standard are to contribute to public health and safety and to the protection of resources, as well as to serve as an outcomes focus for NGWA’s voluntary water-well system professional certification program. While developing the standard, NGWA followed ANSI’s required core principles of openness, balance, lack of dominance and consensus.

ANSI/NGWA-01-14 will be available in the NGWA bookstore soon.
