Crystals will be required to Kill and control algae in water which is flowing than in a body of stagnant water. If possible, curtail the flow of water before treatment and hold dormant for approximately three days after treatment or unti l the algae have begun to die. When preparing a Copper Sulfate Crystals solution in water, the mixing container shou ld be made of plastic, glass, or a painted, enameled, or copper-lined metal container. It is usually best to treat a lgae on a sunny day when the heavy mats of filamentous algae are most likely to be floating on the surface where they can be sprayed directly. If there is some doubt about the concentration to apply , it is best to start with the lower concentration given in the Specific Instructions below. Treatment of algae can result in oxygen loss from decomposition of dead algae. This loss can cause fish suffocation . Therefore, to minimize this hazard , treat no more than one-half of the water area in a single operation and wait at least 14 days between treatments. Begin treatments along the shore and proceed outward in bands to allow fish to move into untreated water. NOTE: If treated water is to be used as a source of potable water, the metallic copper residual must not exceed 1 ppm (4 ppm Copper Sulfate Crystals). CALCULATIONS FOR THE AMOUNT OF WATER IMPOUNDED AND FOR THE AMOUNT OF COPPER SULFATE CRYSTALS TO BE USED: Calcu late water volume as follows: (1) Obtain surface area by measuring of regu lar shaped ponds or mapping of irregular ponds or by reference to previously recorded engineering data or maps. (2) Calculate average depth by sounding in a regular pattern and taking the mean of these readings or by reference to previously obtained data. (3) Multiply surface area in feet by average depth in feet to obtain cubic feet of water volume. (4) Multiply swiace area in acres by average depth in feet to obtain total acre-feet of water volume. CALCULATE WEIGHT OF WATER TO BE TREATED AS FOLLOWS: (1) Multiply volume in cubic feet by 62.44 to obtain total pounds of water, or (2) Mu ltiply vo lume in acre feet by 2 ,720 ,000 to obtain pounds of water. CALCULATIONS OF ACTIVE INGREDIENT TO BE ADDED: To calculate the amount of Copper Sulfate Crysta ls needed to achieve the recommended concentration, multiply the weight of water by the recommended concentration of Copper Sulfate Crysta ls. Since recommended concentrations are normally given in parts per mi llion (ppm), it will first be necessary to convert the value in parts per million to a decimal equivalent. For e xample , 2 ppm is the same as 0.000002 when used in this calculation. Therefore, to calculate the amount of Copper Sulfate Crystals to treat 1 acre-foot of water with 2 ppm Copper Sulfate Crystals (or 0.5 ppm metallic copper), the calculation wou ld be as follows : 0.000002 X 2,720,000 = 5.441bs. Copper Sulfate Crystals CALCULATION OF WATER FLOW IN DITCHES, STREAMS, AND IRRJGATION SYST EMS: The amount of water flow in cubic feet per second Is found by means of a weir or other measuring device. SPECIF IC INSTRUCTIONS SEWER TREATMENT -ROOT DESTROYER* ROOT CONTROL GENERAL INFORMATION : Plant roots can penetrate through small cracks and poorly sealed joints of sewer lines. If not controlled , these small roots will continue to grow larger in number causing breakage, reduced flow, and eventually , flow stoppage . Copper Sulfate Crystals has been known to be an effective means to contro l roots in residential and commercial sewers. COMMERCIAL, INSTITUTIONAL, AND MUNICIPAL SEWERS: ROOT CONTROL IN SEWERS: As a preventive measure, apply into each junction or terminal manhole 2 pounds of Copper Sulfate Crystals every 6 to 12 months. At time of reduced flow (some water flow is essential), add Copper Sulfate Crystals. If flow has not completely stopped , but has a reduced flow due to root masses, add Copper Sulfate Crystals in the next manhole above the reduced flow area. For complete stoppage, penetrate the mass with a rod to enable some flow before treatment. ROOT CONTROL IN STORM DRAINS : Apply when water flow is light. If no water flow, as in dry weather, use a hose to produce a flow. Apply 2 pounds Copper Sulfate Crystals per drain per year. It may be necessary to repeat treatments in 6 month intervals, if drains become nearly plugged. SEWER PUMPS AND FORCE MAINS: At the storage well inlet, place a cloth bag containing 2 pounds of Copper Sulfate Crystals. Repeat in 6 or 12 month intervals, if necessary, RESIDENTIAL OR HOUSEHOLD SEWER SYSTEMS: 4 6.3.A. - Page 127
