Lakewood Water Quality Profile

  • Water Hardness: 12.0 GPG (205.2 PPM)
  • Hardness Level: Very Hard
  • Water Source: State Avg (Outlier Cap, California)

With a hardness of 12.0 GPG, Lakewood's water contains more than triple the mineral content of the national average of ~5 GPG. Every gallon running through your home carries dissolved calcium and magnesium that precipitates out as hard scale.

How Very Hard Water Affects Your Appliances

The cost of 12.0 GPG water shows up on your utility bills and in repair costs. Each year, about 2.8 lbs of rock-hard scale can build up inside your plumbing. This limescale forces your gas water heater to work harder, consuming up to 20% more fuel and cutting its lifespan down to just 9 years from the standard 12-15. You'll see the evidence as a white film on your kettle and find yourself using 30-50% more soap and detergent.

Impact on Skin and Hair

While hard water is not a health risk, its effects on skin and hair are undeniable. The minerals react with soap to form a film, preventing a clean rinse. This often results in dry skin, eczema flare-ups, a persistently itchy scalp, and dull, brittle hair. It is a daily nuisance that affects your personal care routine.

Filtration Guide for Lakewood

For Lakewood's 12.0 GPG water, a salt-free water conditioner is an effective solution to prevent appliance-damaging scale. For the full benefits of soft water—including softer skin and spot-free dishes—a traditional whole-house water softener is recommended. Given a typical installed cost of $1,500, the system pays for itself in roughly 11.9 years from annual savings of $126 in energy and supplies. Complementing this with an under-sink reverse osmosis system for drinking water will also eliminate the need for costly bottled water.

Frequently Asked Questions

Why is Lakewood's water so hard?

Lakewood's water hardness of 12.0 GPG comes from its blended sources. Much of the supply is imported from the Colorado River and Northern California via aqueducts. This water travels over hundreds of miles of rock and soil, picking up minerals like calcium and magnesium along the way.

With 12.0 GPG hardness, do I need a whole-house system or is a faucet filter enough?

A faucet filter only treats a small amount of water for drinking. To protect your pipes, gas water heater, dishwasher, and washing machine from the 2.8 lbs of annual scale buildup, a whole-house system like a water conditioner or softener is necessary.

How does hard water affect my energy bill from the Los Angeles Dept of Water & Power?

Hard water scale acts as insulation inside your water heater's tank. This forces the heating element or gas burner to run longer to heat the water, wasting energy and increasing your bill. With 12.0 GPG water, this can lead to a 15-20% increase in water heating costs.

Data Transparency & Methodology

Water and savings figures for Lakewood, California are generated by our plumbing analytics engine (v1.1). Methodology highlights:

Water hardness (PPM / GPG)

Sourced or inferred from municipal water-quality reporting (including Consumer Confidence Report–style hardness / mineral data where published). Values represent typical service-area water for modeling scale risk—not a lab test for your specific tap.

Economics (scale, appliances, payback)

Engineered estimates — scale buildup potential, water-heater wear, and water-softener payback use industry-typical curves (grain capacity, regeneration salt use, and heater efficiency assumptions) applied to your local hardness and usage profile. Figures are illustrative; a licensed plumber should validate sizing.

Electricity rates (optional cost context)

Where water-heating or pump energy cost appears, EIA state average retail electricity prices ($/kWh) may be used as a benchmark—not your exact utility time-of-use bill.
