Does Seattle Have Hard Water? The Truth Revealed
Seattle generally has soft water, which means it has low concentrations of minerals like calcium and magnesium. This is because Seattle’s water source is primarily surface water from the Cascade Mountains, which is naturally soft. However, the perceived “hardness” can vary slightly depending on the specific location and time of year.
What is Hard Water?
Hard water contains dissolved minerals, primarily calcium and magnesium. While not harmful to drink, it can cause several inconveniences. These include soap scum buildup, difficulty lathering soap, and mineral deposits in pipes and appliances.
Signs of Hard Water
Even though Seattle is known for its soft water, it’s helpful to know the signs of hard water, just in case:
- Soap scum on shower doors and sinks
- Difficulty getting soap to lather
- Scale buildup on faucets and showerheads
- Dry skin and hair
- Spotty dishes after washing
Why Seattle’s Water is Soft
Seattle’s water source is predominantly from the Cedar River Watershed and the South Fork Tolt River Watershed, both located in the Cascade Mountains. The water from these sources flows over granite bedrock, which doesn’t readily dissolve minerals. This results in naturally soft water. According to the Water hardness definition, water with less than 60 mg/L (milligrams per liter) of calcium carbonate is generally considered soft.
Testing Your Water’s Hardness
If you’re concerned about the hardness of your water, you can purchase a water hardness testing kit from most hardware stores or online retailers. These kits typically use test strips or liquid reagents to determine the mineral content of your water. You can also contact Seattle Public Utilities (SPU) to inquire about water quality reports for your area.
FAQs About Seattle Water
Is Seattle water safe to drink?
Yes, Seattle’s water is safe to drink. Seattle Public Utilities (SPU) regularly tests the water supply to ensure it meets or exceeds all federal and state safety standards.
Does soft water affect plumbing?
Soft water can actually be beneficial for plumbing. It helps prevent scale buildup and can even dissolve existing mineral deposits, extending the life of your pipes and appliances.
Why does my water sometimes look cloudy?
Cloudy water is often caused by dissolved air. This is more common during colder months when the water temperature is lower. The cloudiness should disappear within a few minutes.
Does Seattle add fluoride to its water?
Yes, Seattle adds fluoride to its water supply to promote dental health.
Where can I find more information about Seattle’s water quality?
You can find detailed information about Seattle’s water quality on the Seattle Public Utilities (SPU) website.
Summary
Seattle is known for having soft water due to its pristine water sources in the Cascade Mountains. While the perceived hardness can vary slightly, the water generally has low mineral content. If you’re concerned about your water’s hardness, you can easily test it yourself or contact Seattle Public Utilities for more information.
