Torrance Hard Water

How Hard Is Torrance Water?

Torrance’s most recent water quality report doesn’t publish a hardness figure, so a free in-home water test is the best way to know how hard your water is. According to the latest report, Torrance bought about 68% of its water from the Metropolitan Water District and drew the other 32% from local West Coast Basin groundwater wells and a groundwater desalination project, so mineral levels can vary depending on which supply reaches your home.

Frequently Asked Questions

Is Torrance tap water safe to drink?

Yes, Torrance’s tap water meets all state and federal safety standards. The most recent water quality report did detect some substances below their legal limits, such as TTHMs (54.8 ppb average), HAA5 (10.7 ppb average), and uranium (0.07 pCi/L in local groundwater). Arsenic, total chromium, and lead were not detected, though the report doesn’t list Chromium-6 separately.

Is Torrance’s water hard?

Torrance’s most recent water quality report doesn’t list a hardness figure, and because the city blends imported water with local groundwater, hardness can vary from home to home. A free in-home water test will tell you exactly where your water stands. Hard water can lead to limescale buildup, dry skin, and reduced appliance efficiency.

Does Torrance’s water contain PFAS (“Forever Chemicals”)?

Torrance’s most recent water quality report doesn’t list PFAS results for compounds such as PFOA or PFOS, so a free in-home water test is a good place to start. For added peace of mind, many residents choose reverse osmosis or advanced carbon filtration systems to further reduce potential contaminants.

Does Torrance add fluoride to its water?

Yes, fluoride is added to Torrance’s water, and the distribution system averaged about 0.7 ppm, within state and federal guidelines for preventing tooth decay.

What other contaminants are in Torrance’s water?

The most recent water quality report detected the following, all within regulatory limits:

Barium (0.12 ppm in imported MWD water; 0.089 ppm in local groundwater)
TTHMs (54.8 ppb average)
HAA5 (10.7 ppb average)
Uranium (0.07 pCi/L in local groundwater)
Manganese (44.7 ppb in local groundwater, near the 50 ppb secondary standard)
Aluminum (80 ppb in imported MWD water)
Chloride (121.5 ppm in local groundwater, from seawater influence)
Total Dissolved Solids (695.6 ppm average in local groundwater; 540.5 ppm in imported MWD water)

Where does Torrance get its water?

According to the most recent water quality report, Torrance sourced about 68% of its water from the Metropolitan Water District of Southern California (MWD), which imports surface water from the Colorado River through the Colorado River Aqueduct and from Northern California through the California Aqueduct. The remaining 32% comes from local West Coast Basin groundwater wells and a groundwater desalination project.

What is the pH level of Torrance water?

Torrance’s most recent water quality report doesn’t publish a pH value, so a free in-home water test is the best way to find out whether your water leans acidic or alkaline.

Should I use a water filter or softener in Torrance?

Yes, due to hard water and trace contaminants, many residents benefit from whole-house water filters, reverse osmosis systems, and water softeners to improve water quality, taste, and protect appliances.

Does Torrance water have a high total dissolved solids (TDS) level?

Yes. Torrance’s local groundwater averages 695.6 ppm TDS (range 630–760), and imported MWD water, about 68% of the supply, averages 540.5 ppm. Both are above the 500 ppm level California recommends for taste and below the 1,000 ppm upper limit. Reverse osmosis systems are recommended for reducing TDS.
