Highland Park Water Analysis

  • Water Hardness: 5.0 GPG (85.5 PPM)
  • Hardness Level: Moderate
  • Water Source: Municipal System (Surface Water)

At 5.0 GPG, Highland Park's water is on par with the U.S. national average. This measurement means every gallon of water carries a mineral content equivalent to crushing up about five standard aspirin tablets and dissolving them. Over time, these minerals precipitate out of the water and form scale deposits inside your plumbing and water-using appliances.

The Financial Cost of Moderate Hardness

Annually, your home's plumbing system will see about 1.2 lbs of calcium carbonate scale build up from Highland Park's water. This buildup is most costly inside your water heater. Scale acts as insulation, forcing a gas water heater's burner to work harder and longer to heat the water, directly increasing your Public Service Electric & Gas Co utility bill.

This constant strain reduces the expected lifespan of a water heater from the standard 12-15 years down to approximately 12.5 years. You'll also spend more on detergents for laundry and dishwashing, as the minerals in hard water inhibit the effectiveness of soaps.

How Hard Water Affects Your Family

Moderately hard water is safe to drink but can be harsh on your body. The minerals prevent soap from lathering and rinsing completely, leaving behind a residue that can cause dry skin, exacerbate eczema, and leave hair feeling dull and difficult to manage. This same residue creates the familiar soap scum on shower tiles and glass doors.

Choosing the Right Filtration for Highland Park

With a moderate hardness of 5.0 GPG, a full whole-house water softener is not a cost-effective solution. The modest potential savings of $54 per year results in a payback period of almost 28 years for a typical system installation. A more practical strategy involves targeted filtration:

  • For Apartments & General Use: A quality pitcher filter or faucet-mounted filter is an excellent choice. It will significantly improve the taste of your drinking water by removing chlorine and some minerals.
  • For Homeowners: An under-sink Reverse Osmosis (RO) system offers the highest quality drinking water and completely eliminates the expense and waste of bottled water. For moderate hardness, whole-house treatment is not typically recommended.

Frequently Asked Questions

Why is the water in Highland Park moderately hard?

Highland Park's water is primarily sourced from surface waters like the Raritan River. As water travels over and through the ground, it dissolves naturally occurring minerals like calcium and magnesium from rocks and soil, resulting in a moderate hardness level of 5.0 GPG.

What's the best water filter for a Highland Park apartment?

For an apartment, a simple, non-permanent solution is best. A high-quality water pitcher or a faucet-mount filter provides excellent tasting water for drinking and cooking without any installation. A whole-house system is unnecessary for this water hardness level.

How much does 5.0 GPG hardness affect the taste of my coffee or tea?

The minerals in moderately hard water can make coffee and tea taste slightly bitter or chalky. The minerals can also lead to a cloudy film on the surface of hot beverages. Using filtered water from a pitcher or under-sink system will result in a noticeably cleaner, better taste.
