Abstract
A method of chemically treating bodies of water such as lakes by accurately dispensing a treatment agent into the water in an amount based upon the volume of water being passed over continuously determined by detection means for the speed of the boat carrying the dispensing means for the speed of the boat carrying the dispensing means and the depth of the water being passed over. When the water is being neutralized by the chemical addition, the pH of the water may also be continuously monitored. A boat particularly designed and adapted for practicing the method is also disclosed. The boat includes a main tank partially supported or floated by the water at least when the tank is loaded and also stabilized and partially or additionally supported by lateral pontoons when loaded. The boat includes sparging, or mixing, and spraying means to dispense the treatment agent.
