How Hard Water Affects Your Family
While hard water is not considered a direct health hazard, its effects are noticeable daily. The high mineral content prevents soap from lathering properly, leaving behind a residue on your skin and hair.
- Skin and Hair: Many residents experience dry, itchy skin, irritated scalp, and dull, brittle hair. The soap film can clog pores and aggravate conditions like eczema.
- Bathing: It becomes difficult to feel truly clean, as a sticky soap scum layer is left behind on skin after showering.
- Sensitive Skin: When preparing baby formula or bathing infants, the mineral-heavy water can be particularly harsh on sensitive skin.
Choosing the Right Filtration System for Oberlin
With water hardness at 13.7 GPG, you have a couple of effective options depending on your goals.
- Salt-Free Water Conditioner: For many households, a salt-free conditioner is sufficient. It won't remove the minerals, but it changes their structure to prevent them from forming hard scale inside pipes and on heating elements. This is a great, low-maintenance option for appliance protection.
- Whole-House Water Softener: If you also want the 'soft water' benefits—no soap scum, better lather, softer skin—a traditional salt-based softener is the best choice. For drinking water, it's often paired with an under-sink reverse osmosis (RO) system to remove the sodium and provide purified water.
The Payback: A whole-house softener (around $1,500 installed) pays for itself in approximately 10.4 years through savings of $144 per year on energy, detergent, and deferred appliance replacement costs. This doesn't even factor in the $600-900 per year an average family spends on bottled water, which an RO system eliminates entirely.
