Stateline water-quality monitoring of streams in Arkansas with potential nonpoint contamination from cattle and poultry operations. Monthly stream sampling in Arkansas to determine potential contamination from nearby poultry operations. Carolina ground water. Carolina ground water.
Sources being evaluated include poultry waste, swine waste, human waste, and commercial fertilizer.
