Conclusions of the study were consistent with current findings on NPS of pollution, namely that increased percentage of impervious areas associated with urbanized areas correlate with increased organic and inorganic substances. To provide a meaningful, implementable tool, based on these findings, the USDA developed groupings of Best Management Practices (BMP's) applicable to each specific subwatershed (Appendix A). The wastewater treatment plants in the Great Swamp watershed have been a major source of contention over the years. The 1991 Final EIS on the Upper Passaic River Basin 201 Facilities Plan plus the Great Swamp Water Quality Study evaluated the impacts of the Chatham Township (#1) and Morris-Woodland WWTP on the Black and Loantaka Brooks respectively, as well as on the Great Swamp National Wildlife Refuge. It was determined that under base flow conditions and even more so during storm flow conditions, "the discharges of treated wastewater from the Morris-Woodland and Chatham Township WWTP'S generated significantly elevated nutrient concentrations (orthophosphate, total phosphorus, and total soluble inorganic nitrogen) in their receiving waters. The principal exception to these findings occurred on Loantaka Brook, where the difference in nitrate concentrations in the brook upstream and downstream of the Morris-Woodland 14 WWTP discharge were negligible." Malfunctions of the Morris Township Woodland WWTP resulted in major fishkills in Loantaka Brook during the summers of 1988 and 1990. Nonpoint sources were also determined to be contributing substantial nutrient loadings to Loantaka and Black Brooks particularly by way of stormwater runoff. The Great Swamp Water Quality Study reported the positive impact this wetlands complex had on base flow water quality in the Great and Black Brooks. Nutrient measurements taken upstream and at the end of the swamp indicated equal or diminished concentration. This function was repeated during storm events. The findings confirmed the hypothesis that the Great Swamp acts as a nutrient sink. With DEP's required upgrade to Class 4 treatment, nutrient loadings from both WWTP's are anticipated to be reduced. The improved nutrient removal is expected to prevent future surface water algal blooms; and UV disinfection technology will eliminate chlorination of the wastewater. The reduction in point source pollution suggests that emphasis be placed on control of NPS's of pollution. Increased hydraulic loadings to tributary streams as a result of future development and associated impervious surfaces were predicted. In addition "projected increases in the development of undeveloped lands will increase the non-point source (stormwater) loadings of tributary streams, while reducing base flows. . ." 15 Extensive collection of water quality and quantity data, albeit disjointed, has provided a basis for discussion regarding this watershed’s management. The inconclusive nature of many of the studies demand a commitment to continued and long term data collection. 14 US EPA, Final Environmental Impact Statement on the Upper Passaic River Basin 201 Facilities Plan, in Morris, Somerset and Union Counties, New Jersey, Sept. 1991, 5-38. 15 US EPA, Final Environmental Impact Statement 5-40. 88 Surface Water
