The purpose of this experiment was to determine how effective electromagnetic waves could be at reducing calcium hardness in a body of water as well as see how the makeup of the water (free calcium levels, total calcium levels, pH, alkalinity, and surface tension) were affected over the span of testing. A vary of four different nominal calcium hardness levels, ranging from 80 mg/L \u2014 240 mg/L of calcium in terms of calcium hardness were tested over a span of thirty minutes with samples being taking once every ten minutes. Data collection indicates that there is a noticeable decrease in free calcium, total calcium, and pH over a span of thirty minutes using the electromagnetic device, however, no noticeable trend can be made for the alkalinity and surface tension. Errors can be stated to be caused by lack of protocol for calcium hardness creation as well as needed updates for procedures such as alkalinity and surface tension testing. It can be deduced that the process is favorable, but it cannot be concluded as to whether to not this device can become a sustainable alternative to salt-based water softeners.
