Water Quality Details for Alexandria, LA
What 90 PPM Means for Your Home in Alexandria
At 90 ppm, Alexandria'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 Alexandria 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 City of Alexandria Utilities
Alexandria's water is supplied by City of Alexandria Utilities and sourced primarily from underground aquifers accessed through deep wells. Groundwater has been naturally filtered through rock and soil, which makes it generally free of biological contaminants but higher in dissolved minerals. The 90 ppm hardness in Alexandria results from water percolating through limestone, chalk, or dolomite formations underground, dissolving calcium and magnesium along the way. The water has a pH of 7.3, which is near neutral, and total dissolved solids of 140 ppm (moderate).
Estimated Cost of Hard Water in Alexandria
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 Alexandria household of 2.5 people with water at 90 ppm (5.3 gpg), this translates to approximately $4 per year. Over 10 years, that adds up to $40 in avoidable costs — often more than the total cost of installing and operating a water softener.
