The well casing must be certified by the manufacturer to meet ASTM Standard A 53-90b and may not be mill reject. Casing corrected to meet standards is acceptable.
If steel well casing five inches in diameter or larger will be pressure-grouted with cement grout from the top of the producing formation up to the bottom of the pitless adapter or unit or to the ground surface, casing with a minimum wall thickness of 0.250 inches must be used.
