Periodically collect the discharge water and check for <br /> clarity and total settleable solids (TSS) with an Imhoff <br /> cone. Development is considered complete when the discharge <br /> water is relatively clear, the TSS reading is at or below <br /> 150, parts per million by weight (0. 075 ml of material in the <br /> Imhoff cone) ,- and a minimum of three well volumes of water <br /> have been removed. For slow recharging wells, development <br /> is considered complete upon removal of the minimum of three <br /> well volumes _ <br /> E_ Measure and record the water level after completion_ <br /> F_ Transmit to Engineer. <br /> G. Water may be discharged to the ground surface_ <br /> SURFACE COMPLETION: <br /> A_ Install a protective steel casing and concrete pad as shown <br /> on the drawings_ <br /> B_ Install bollards for monitoring well as directed by the <br /> engineer_ <br /> C_ The Contractor shall paint steel casing and bollards with <br /> two coats of rust-preventive, safety-yellow colored paint at <br /> the completion of the project- - <br /> D_ The Contractor shall survey the top of.
