Hard water

Lansing draws from the Great Lakes, the largest freshwater system in the world. At 168 PPM, the water is hard from the basin's limestone geology. In older industrial cities around the Great Lakes, lead from aging service lines is often a more urgent concern than hardness.

What Lansing's Water Means for Your Home

Lansing's water is hard at 168 PPM. This level of hardness causes gradual scale accumulation on plumbing fixtures, inside water heaters, and on dishware. While not as aggressive as cities in the 200+ PPM range, homeowners who install a water softener or salt-free conditioner typically notice improved soap lathering, cleaner dishes, and longer appliance lifespans.

Beyond hardness, Lansing's water quality is generally within EPA guidelines for regulated contaminants. Chlorine is present at 1 mg/L as a disinfectant residual, which is normal for municipal water systems. If you notice a pool-like taste or experience dry skin, a whole-house carbon filter is the most common and affordable solution. For homeowners who want to understand the full picture, requesting your utility's annual Consumer Confidence Report provides neighborhood-level data.

Recommendations for Lansing Homes

💧 Water Softener or Conditioner
At 168 PPM, Lansing's water is hard. You will see gradual scale buildup on fixtures and inside water heaters. A salt-based softener removes hardness completely, while a salt-free conditioner prevents scale without removing the minerals. Your choice depends on whether you want soft-feeling water or just scale prevention.

Frequently Asked Questions About Lansing Water

Is Lansing tap water safe to drink?
Lansing's water meets EPA legal standards for drinking water safety. However, legal limits and health-optimal levels are different things. Review the contaminant table above for specific numbers and how they compare to both legal limits and health guidelines.
Do I need a water softener in Lansing?
It is worth considering. At 168 PPM, Lansing's water is hard. You will notice gradual scale buildup in pipes and on fixtures over time. A salt-based softener extends appliance life and improves soap efficiency. A salt-free conditioner is a lower-maintenance alternative if you primarily want to prevent scale.
What water filter is best for Lansing?
The best filter depends on which contaminants you want to address. See our softener vs. filter guide to understand the difference between these categories.
Where does Lansing's water come from?
Lansing's drinking water is sourced from Groundwater wells and treated by Lansing BWL. Lansing draws from the Great Lakes, the largest freshwater system in the world. At 168 PPM, the water is hard from the basin's limestone geology.
What is the hardness of Lansing water in grains per gallon?
Lansing's water hardness is 9.8 grains per gallon (GPG), which equals 168 parts per million (PPM). This is classified as hard. To convert: 1 GPG = 17.1 PPM.
Does Lansing water damage tankless water heaters?
Yes. Most tankless water heater manufacturers recommend water hardness below 7 to 11 GPG (120 to 188 PPM). At 9.8 GPG, Lansing's water exceeds this threshold. Scale buildup inside the heat exchanger reduces efficiency and can void the manufacturer's warranty. A water softener installed upstream of the tankless heater is the standard solution.
Is Lansing water safe for babies and infants?
Lansing's water meets all EPA safety standards and is generally considered safe for preparing infant formula. The hardness minerals (calcium and magnesium) are not harmful. If your home has older plumbing, running cold water for 30 seconds before use is a good precaution to flush any lead from pipes.
How much does hard water cost a Lansing household per year?
At 168 PPM, hard water costs the average Lansing household an estimated $800 to $1,200 per year in hidden costs. This includes 15 to 25 percent higher water heating bills from scale insulation, 50 to 75 percent more soap and detergent usage, shorter appliance lifespans (water heaters, dishwashers, washing machines), and increased plumbing maintenance. A water softener typically costs $600 to $1,500 installed and $50 to $100 per year in salt, which means most Lansing households see a return on investment within 1 to 2 years.
