Author(s): Gerstein, J M; Lewis, D J; Rodrigues, K; Harper, J M; Kabashima, J | Abstract: Nonpoint source (NPS), common in agriculture, reaches the environment as runoff from a field, not output from a waste pipe. Its control and regulation are also different from other types of pollution that may seem more familiar.
