The well is to be flushed until the turbidity of the water is < 1 NTU before the system may be used for drinking water.[2] Trade name may include numeric suffix corresponding to the quantity of fluid to which the pre-measured packaged product is added.

[1] These products are designed to be flushed out prior to using the system for drinking water. Before being placed into service, the well is to be properly flushed according to the manufacturer's use instructions. Certification of these products is based on the well drilling model with the following assumptions: - The amount of well drilling fluid used is 3780 L (1000 U.S. gallons) to which the drilling fluid has been added at the manufacturer's recommended level. - The aquifer contains 3.1 million liters of water (815,000 gallons) based on a 0.5 acre aquifer of 6.1 meter depth (20 ft.) and 25% porosity. - The bore hole is 61 meters in total depth (200 ft.), the screen is 6.1 meters in length (20 ft.), and the bore hole is 25.4 cm. in diameter (10 in.). - The amount of well drilling fluid removed from the well during construction is equal to the combined volumes of the casing and the screen, plus an additional amount removed through the well disinfection and development (90% removed). - This product should not be used in constructing wells in highly porous formations, such as cavernous limestone.[2] This product is designed to be used off-line following manufacturer's use instructions. The well is to be flushed until the turbidity of the water is < 1 NTU before the system may be used for drinking water.[PC] Polyacrylamide Products Certified by NSF International comply with 40 CFR 141.111 requirements for percent monomer and dose.

[1] This product is designed to be used off-line and flushed out prior to using the system for drinking water, following manufacturer's use instructions.[2] The pH and conductivity of the influent and effluent water should be monitored to ensure that all traces of the product have been removed before placing into service.
