California Stream Condition Index (Csci) Score Analysis Of Streams Sampled From 1998 To 2017 In The San Francisco Bay Region, Jenna Rais
Master's Projects and Capstones
Human impacts to California’s streams have altered the state’s riparian and hydrological landscape. This is a critical issue with regard to natural resources, including ecosystem services such as water availability and water quality. Regulations have a limited amount of impact on the improvement of this landscape and can also become complicated by politics. Scientific advances have developed ways to quantify and describe the quality of streams, this includes the development of the California Stream Condition Index (CSCI) which is based on benthic macroinvertebrate (BMI) population numbers and functions. This index allows scientists to not only score the quality of a …
Evaluation Of The Development And Effectiveness Of Copper Total Maximum Daily Loads (Tmdls) To Achieve Marine Water Quality Criteria, Joanna Florer
Evaluation Of The Development And Effectiveness Of Copper Total Maximum Daily Loads (Tmdls) To Achieve Marine Water Quality Criteria, Joanna Florer
Master's Projects and Capstones
Elevated concentrations of certain chemicals in surface water are known to be toxic to aquatic organisms (e.g., barnacles, algae, and fish). For a number of these chemicals (e.g., tributyltin [TBT], copper) federal and state water quality standards exist to protect aquatic organisms. As a means to comply with water quality standards, regulatory agencies establish Total Maximum Daily Loads (TMDLs) to reduce concentrations of toxic chemicals from entering waterways. A TMDL determines the maximum amount of pollutant loading a water body can sustain and still achieve water quality standards; they are developed to ensure that surface water concentrations meet applicable criteria. …
