WERF Awards Contracts To Continue Nutrient Research

The Water Environment Research Foundation (WERF; Alexandria, Va.) awarded two contracts to Brown and Caldwell (Walnut Creek, Calif.) that build upon WERF’s current nutrient research.

The first contract is for the project, “Model Guidance for Developing Site Specific Nutrient Goals – Demonstration, Boulder Creek, Colo.” The research team is using available monitoring data for Boulder Creek to evaluate potential nutrient management scenarios and using WERF’s guidance to develop water-body-specific nutrient goals. The project will demonstrate the viability of WERF’s method for setting water-body-specific nutrient targets in Colorado. It also will identify key results that can be transferred to other locations in Colorado and throughout the U.S.

The second project, “Nutrient Recovery through Urine Separation,” is a part of WERF’s research through the U.S. Environmental Protection Agency’s National Center for Resource Recovery and Nutrient Management. The Brown and Caldwell team is working with Hampton Roads (Va.) Sanitation District (HRSD) to plan and implement urine collection and storage systems, conduct field- and lab-based experiments addressing scale and odor issues associated with urine collection and storage, and construct a struvite pilot plant at HRSD.
