Charge Balance Error (CBE) Calculator

The Charge Balance Error (CBE) Calculator evaluates the analytical accuracy of groundwater chemistry data by comparing the total cation and anion concentrations in milliequivalents per liter (meq/L). A CBE within ±5% generally indicates reliable water quality analysis.

How to Use

1. Enter the concentrations of major cations and anions in mg/L.

2. Click Calculate to convert the values to meq/L automatically.

3. View the Charge Balance Error (%) and the corresponding data quality assessment.
