Prima Deshecha Landfill Bioassessment Monitoring

MBC performed bioassessment monitoring at the landfill project site prior to construction and after construction. The landfill is located in San Juan Capistrano, CA which is operated by the County of Orange, Waste & Recycling Department. MBC performed the streambed biological assessments following California Stream Bioassessment Procedure (CSBP) as well as the So. California Index of Biotic Integrity (IBI) . The CSBP measures a stream’s benthic macroinvertebrate (BMI) community and its physical, biological and chemical disturbance before and after the landfill activities which could affect a variety of invertebrate species that have varying sensitivities from these disturbances. The IBI uses species-specific tolerance values and community composition to determine habitat health. The bioassessment also incorporated Surface Water Ambient Monitoring Program (SWAMP) physical habitat assessment protocols. Following the construction activities, the results of both surveys were compared to assess any impacts.
