Impacts of Non-Point Source Pollution Regulations on Mississippi Agriculture [PDF]

Journal of Agricultural and Applied Economics, 1979
The Federal Water Pollution Control Act of 1972, PL92-500, established the goals of making the nation's streams and lakes swimmable and fishable by 1983 and eliminating both point and non-point pollution discharge by 1985. Implementation of this act, even if carried out uniformly and on the basis of scientifically determined information, could have far-
