CCME’s Sediment, Soil and Water Quality Indices provide a convenient means of summarizing complex data and facilitating its communication.

The SeQI, SoQI and WQI calculators are Microsoft Excel workbooks which contain macros. Your network settings may affect your ability to download the calculator and/or your default macro settings in Microsoft Excel may affect your ability to open the calculator file. If you get a “macro error message”, go to the Microsoft Excel menu bar, select Tools, click on Macro, click on Security, and change the setting from high to medium or low. You may have to close and re-open the file. When you open the file, you will find directions under the “Getting Started” button.

For optimal functioning of the SeQI, SoQI and WQI calculators, it is recommended that you save a copy of the Microsoft Excel file to your computer, rather than opening and using it online.
