Communities are becoming increasingly involved in land and water management decisions that affect their quality of life. Access to data and information for making informed decisions, however, has been a limiting factor, both in terms of availability and understanding. This project addresses a dominant cause of impaired water quality in urban lakes: the widespread use of phosphorus-containing fertilizers on phosphorus (P)-rich soils in urban and suburban watersheds and the discharge of this excess P in storm water runoff.
We propose to conduct a community-based experiment comparing the downstream effects of broad-scale application of standard and P-free fertilizers in urban watersheds, use real-time, in-stream flow monitors to assess the effects of alum injection to remove phosphorus from storm water runoff, and corroborate the results with an in-lake real-time sampling station.
Approach:Environmental Parameters and Information Delivery: We will record runoff volume and P loading from watersheds, in-stream flow and P concentrations, and in-lake dissolved oxygen, pH, temperature, conductivity and turbidity. Information on historic and current water quality will be delivered via the Internet, information kiosks, and programmatic activities.
Expected Results:This project provides public access to information important to understanding dominant factors affecting the quality of surface waters in highly urban environments. The ultimate project result is behavior modifications lead to improved water quality.
Improvements in Risk Assessment: Public understanding of factors affecting the quality of surface waters will be improved by providing information needed to make sound decisions on personal actions that have cumulative environmental effects. Data and information management and delivery systems will be designed for easy adaptation to other communities, and will be linked with similar real-time water monitoring projects in other urban areas across the nation.
