Groundwater was analyzed and found to have the following composition, with all concentrations as CaCO3:

1. Draw a bar diagram of the untreated water.

2. Establish the hardness distribution.

3. Calculate the chemicals requirements (chemical dosage) for softening the water.

4. Estimate the hardness of the treated water.
