What 105 PPM Means for Your Home in Aurora
At 105 ppm, Aurora's water is classified as slightly hard. You may notice minor water spots on dishes and glassware after they dry, and there might be a thin film on glass shower doors over time. However, these effects are cosmetic rather than damaging. Your plumbing and appliances are not at significant risk of scale damage at this level. Most households in Aurora operate perfectly well without a water softener. If the minor spotting bothers you, a simple rinse aid in your dishwasher or an occasional vinegar wipe on fixtures is usually sufficient. Some homeowners with sensitive skin or eczema may still prefer a softener for bathing comfort.
Water Source and Treatment at Aurora Water
Aurora's water is supplied by Aurora Water and sourced primarily from a combination of surface water and groundwater sources. This blended approach helps the utility balance water quality, availability, and seasonal demand. The 105 ppm hardness in Aurora reflects the weighted average of these different sources, and actual hardness may fluctuate slightly depending on which sources are active at any given time. The water has a pH of 7.5, which is near neutral, and total dissolved solids of 155 ppm (moderate).
Estimated Cost of Hard Water in Aurora
The Water Quality Association estimates that hard water costs the average household about 30 cents per grain per gallon per person per year in combined expenses from increased soap and detergent usage, reduced appliance efficiency, higher energy bills from scale-encrusted water heaters, and premature appliance and plumbing replacement. For a typical Aurora household of 2.5 people with water at 105 ppm (6.1 gpg), this translates to approximately $5 per year. Over 10 years, that adds up to $46 in avoidable costs — often more than the total cost of installing and operating a water softener.
