|---|---|---|
| Catskill | 6.2 | 1.5 |
| Delaware | 8.1 | 1.8 |
| Croton | 9.4 | 2.3 |
These low levels of calcium and magnesium make NYC’s water soft. It has an average hardness of just 1.1 grains per gallon. Water with a hardness over 7 gpg is hard, and over 10.5 gpg is very hard.
Differences Between Hard and Soft Water
Hard water has more calcium and magnesium than soft water. This can cause problems like:
- Scale buildup in pipes and appliances
- Reduced efficiency of water heaters
- Increased soap and detergent consumption
- Dry skin and hair after washing
Soft water, like NYC’s, avoids these issues. Its low mineral content means less scale, longer appliance life, and better washing. So, New Yorkers enjoy soft water without needing extra treatments.
