Covina Water Quality Data
- Water Hardness: 12.0 GPG / 205.2 PPM
- Hardness Level: Very Hard
- Water Source: Regional Blend (Imported & Groundwater)
At 12.0 GPG, Covina's water is more than double the U.S. national average of approximately 5 GPG. This measurement means that for every gallon of water that passes through your pipes, a significant amount of dissolved calcium and magnesium—equivalent to 12 grains of rock—is being carried with it.
The Financial Cost of Hard Water on Your Home
The high mineral content in Covina's water directly translates to higher household costs. Over a year, your home's plumbing and appliances can accumulate 2.8 lbs of calcium carbonate scale. This buildup has significant consequences:
- Water Heaters: Scale acts as insulation between the gas burner or electric element and the water. At 12 GPG, your heater may work up to 20% harder to heat water, inflating your utility bills. This constant strain shortens its lifespan from a typical 12-15 years down to just 9 years.
- Washing Machines & Dishwashers: Hard water requires 30-50% more soap and detergent to create a lather, increasing your spending on cleaning supplies. The mineral residue also leads to stiff, faded laundry and spotted dishes.
- Kettles & Coffee Makers: The visible white crust you see inside these small appliances is a clear indicator of the scale building up unseen in your larger, more expensive systems.
Effects of Hard Water on Skin and Hair
While hard water poses no direct health risks for consumption, it significantly impacts daily life. The high mineral content prevents soap from lathering and rinsing properly, leaving a film on your skin and hair. This can lead to:
- Dry, itchy skin and aggravated eczema conditions.
- Dull, brittle hair and an irritated scalp.
- Soap scum buildup on shower doors, tubs, and sinks.
For families, preparing baby formula with very hard water can be a consideration, although it is generally considered safe.
Choosing the Right Filtration System for Covina
With a hardness level of 12.0 GPG, treating your water is a financially sound decision. Your options depend on your goals:
- Salt-Free Water Conditioner: This is an excellent choice for preventing scale buildup without introducing salt into your water. It protects your plumbing and appliances from mineral deposits.
- Whole-House Water Softener: For those who also want the 'soft water' benefits (better lathering, smoother skin), a traditional salt-based softener is the most effective solution. An installed system, costing around $1,500, can pay for itself in 11.9 years through annual savings of $126 on energy, detergents, and appliance longevity.
- Drinking Water: For purified drinking water, an under-sink Reverse Osmosis (RO) system is a great addition to either whole-house system. It removes nearly all dissolved solids and eliminates the need for bottled water, which costs the average family $600-$900 per year.
