As rainwater falls it is naturally soft. Entering the ground and into waterways, it gathers a variety of minerals, including chalk, lime, calcium and magnesium, transferring the water from soft to hard.

These minerals also assist in providing taste and nutrition for our drinking water. Baton Rouge claims the second-best drinking water in the country.

Years ago, at the approach of a shower, Mom would position a pot on the patio to capture the “soft rain.” She also insisted that it was much softer than the tap water for shampooing her hair.

Yesterday’s column noted clothes that remained “on the line” during a shower. She didn’t know that hard water makes clothes look dingy as soap is less effective because of magnesium and calcium.
