Lake Darling was once among the state's most polluted. Silt had shrunk the 1952 reservoir from 305 to 267 acres and high bacteria levels often closed it to swimming. Today, thanks to 80% participation of landowners and farmers, terraces and farm ponds have cut sediment reaching the lake from about 16,000 tons a year to less than 7,000.Charles W.

Solve and click "Comments" to give the answers!A hog farm produces 5,000,000 gallons of liquid waste annually. It is stored in an earthen lagoon until it can be surface incorporated into a 400 acre field. The composition of the liquid waste, on a weight basis is 95% water and 5% solids. An elemental analysis of a dried sample of the solid fraction showed it to be 45% carbon, 40% oxygen, 10% hydrogen, 1% nitrogen, 3% phosphorus, and 1% potassium. The dried solid fraction also contains 12 ppm of lead. There was no lead in the soil prior to this waste being applied to it.<br /><br />1. Determine the dry weight (tons) of solids that the farmer annually applies to each acre.<br />2. In how many years would the state’s tolerable limit of 5 pounds of lead per acre-furrow-slice be reached if the farmer’s liquid waste application rate is 100 tons per acre per year.Charles W.
