Even when best management practices are employed, dealers can have 2000 to 7000 gallons of fertilizer/pesticide rinsewaters each year that cannot be used on nonlabel crops or indiscriminately applied or disposed of without violating Environmental Protection Agency (EPA) pesticide label application regulations. A novel, easily implemented solution for reduction of these rinsewaters has been developed at the University of Alabama at Huntsville (UAH) working with researchers from the Tennessee Valley Authority`s (TVA) National Fertilizer and Environmental Research Center (NFERC), Muscle Shoals, Alabama. Researchers have developed a passive flat-plate solar evaporator. It is a stainless steel/glass unit approximately 8inches {times} 7inches {times} 5inches, and can be produced on an assembly line basis for less than $4000 each. NFERC technologists will use these units for environmental research and demonstration projects at other universities and dealers this year. Each unit can evaporate 900--1200 gallons of water per year.
