CASQA conducted a comprehensive review of existing approaches and tools for use in evaluating source contributions (outcome level 4) from key source categories and target audiences. This work effort was coordinated amongst three CASQA subcommittees (Effectiveness Assessment, Best Management Practices, and Watershed and Impaired Waters).
As a part of the comprehensive review of existing approaches and tools for use in evaluating source contributions (outcome level 4), in March 2018 CASQA developed a web-based database that allows users to identify the tools that may be used to estimate or calculate the source contributions. The database is searchable by entering key input parameters based on the Pollutant/Condition of Concern (POC / COC), Source, and/or Best Management Practices (BMP) combination(s). It is anticipated that the database will be updated as new information and tools are developed.
- For a full discussion of the development and use of the database, download the CASQA Source Contribution Tools and Methodologies Guidance document (PDF) (July 2018).
- To view the current, defined relationships, download the matrix of Pollutant/Condition of Concern and BMP relationships (PDF) or the matrix of Pollutant/Condition of Concern and Source relationships (PDF).
To Use the Online Database
- Select from any or all of the filters to identify the desired combination of input parameters. View the example search scenarios below for ideas.
- As the selections are made, other filters will be automatically updated to reflect available options based on the previous selection. Results will automatically update upon each selection. SC indicates “Source Control” and TC indicates “Treatment Control”
