Section 534.430 - Means to measure level of water in well required1. Except as otherwise provided in subsection 3, each well that is drilled must have:(a) An access port near the top of the casing or in the casing cover that is not less than 2 inches in diameter;(b) A commercially manufactured sanitary well cap that may be easily removed to determine the level of water in the well; or(c) A reliable electronic means to measure the level of water in the well.2. An access port must have a watertight, screw-type cap seal or a removable plug to prevent contamination and must be kept closed.3. On wells that are 8 5/8 inches in diameter or smaller, the access may be a 1-inch hole at the top of the casing or in the casing cover with a removable plug or bolt.4. As used in this section, "access port" means an opening in the top of a well casing in the form of a tapped hole and plug or a capped pipe welded on the casing to permit entry of a device to measure the water level of the well.Nev.
