Ecological Engineering Research Program

The Ecological Engineering Research Program (EERP) at the University of the Pacific is the lead scientific agency on several water quality and ecosystem restoration projects focused on understanding and improving water quality in the San Joaquin River (SJR). EERP projects include the development of a mass balance on phytoplankton and oxygen demanding materials in the SJR, evaluation of organic carbon sources and fate in the SJR, studies of wetland ecosystems, and studies examining the impact of current agricultural best management practices (BMPs) on water quality.

Research Interests

  • Scientifically based best management practices (BMP) for agricultural non-point source discharges
  • Algal growth process in the San Joaquin River (SJR) including community dynamics, settling and grazing by zooplankton
  • Influences of diffuse source discharges on algal growth
  • Organic carbon cycling in wetlands
  • Scientific investigation of sustainable agriculture in the Central Valley
  • Management of agricultural ecosystems in Mediterranean and arid climates
  • Analysis of recovered hydraulic fracturing fluid
  • Development of treatment for recovered hydraulic fracturing fluid for re-use and anvironmentally safe disposal

Lab Capabilities

The EERP has extensive lab capability with three dedicated labs: water quality, analytical, and biomass energy.  They are currently supporting the San Joaquin Dissolved Oxygen - Total Maximum Daily Load Project.  For more in-depth information visit the link below or click here.

Field Operations

EERP field operations make in-situ water quality and flow measurements, collect river, agricultural, and estuarine surface water samples to understand the fate and transport of non-point source pollution and to provide scientifically based recommendations for agricultural best management practices. Field operations support student and faculty research while working in collaboration with stakeholders.
