A100-84: AWWA Standard for Water Wells (PDF)

This standard covers well diameters ranging from 8 in. through 30 in. (203 mm through 762 mm) and is designed to meet the needs of industries, municipalities, or similar interests. The history of the standard, major revisions from previous editions, information regarding the use of the standard, and a special notice regarding screen inlet velocity are discussed in the foreword. Sections 1 through 13 discuss the following topics: scope of the standard, definitions, abbreviations, referenced standards, contractor submittals, permits, and protection of groundwater resources; formation sampling, geophysical logging, water sampling and analyses, reports, and identification of principal aquifers; construction methods, drilling fluids, and final reports on construction; well casing diameter, wall thickness, material, drive shoes, installation, seating or sealing, and completion of well site; well screen diameter, screen length, screen aperture size, material, screen strength, screen construction, screen joints and spacers, and sealing bottom of screens; gravel pack thickness and location, materials and impurities, graduation, samples, delivery and storage, methods of installation, and disinfection; grouting and sealing requirements, materials, and methods of placement; tolerances of plumbness and alignment and depth of applied tolerances; well development tests, measurements of operating parameters during development, and development records; performance testing methods, water level measurements, pumping test interruption, and records and reports; well disinfectants, disinfection procedures, and disinfection of gravel-pack wells; water quality testing considerations, sampling procedures, and analytical procedures; and sealing requirements and records of abandonment procedures for test holes, partially completed wells, and completed wells. Appendices address gravel pack installation methods; methods of placement for grouting and sealing; procedure for testing plumbness and alignment; methods of measuring operating parameters during development; well disinfection; suggested methods for water sampling; corrosion; factors influencing the duration of pumping tests; abandonment of test holes, partially completed wells, and completed wells; geophysical bore-hole logs; types of wells; and collapse strength of steel well casing.
