A slug test was made with a piezometer that had a casing radius of 2.54 cm and a screen of radius 2.54 cm. A slug of 4000 cm³
of water was injected; this raised the water level by 197.3 cm. The well completely penetrated a confined stratum that was 2.3 m thick. The decline in head with time is given in the following chart:
