Abstract |
The upper portions of the Chesapeake Bay and its tidal tributaries are currently suffering from an insidious eutrophication problem as evidenced by the increased frequency and persistence of undesirable algal blooms and the dramatic changes in the Bay's natural flora which have recently been experienced. Water quality monitoring data collected between 1968 and 1971 have shown an upward trend in phosphorus levels and indicated that inorganic nitrogen may presently be the growth rate-limiting nutrient since it is almost nonexistent during peak bloom conditions. In order to limit the maximum algal standing crop to 40 ug/l chlorophyll a, it was determined that total phosphorus and inorganic nitrogen concentrations should not exceed 0.12 mg/l and 0.8 mg/l, respectively. The achievement of these concentrations necessitates the institution of a considerable abatement program in the Susquehanna River Basin and the Baltimore metro area. (Modified author abstract) |
