How Summer Heat Affects Your Home’s Water Quality

As temperatures rise across Vermont during the summer months, homeowners in Washington, Lamoille, Addison, Orleans, Caledonia, Chittenden, Essex, Franklin, Grand Isle, Orange, Rutland, Windham, and Windsor counties may notice changes in their water quality. Warm weather can introduce or worsen certain water issues, especially for those relying on private wells or aging municipal infrastructure. Understanding how summer affects water quality—and how to address these seasonal shifts—can help keep drinking water safe, fresh, and healthy all season long.

The Impact of Heat on Water Systems

Summer heat can influence water quality in several ways, both in well water systems and municipal sources. These changes can alter taste, safety, and overall usability.

Common Heat-Related Water Issues:

Bacterial Growth: Higher temperatures can accelerate microbial activity in water sources, increasing the presence of coliform bacteria and algae.

Lower Water Tables: Drought conditions or increased water use can lower well levels, pulling in sediment or introducing contaminants.

Pipe Leaching: Heat can exacerbate the leaching of metals such as lead or copper from old plumbing systems.

Increased Demand on Municipal Systems: Greater water usage can strain city supplies and reduce the effectiveness of treatment, leading to changes in taste or odor.

Private Well Owners: What to Watch For

Homeowners with private wells are especially vulnerable to heat-related water quality changes. Unlike municipal water, well water is not treated or tested unless action is taken by the homeowner.

Summer Concerns for Well Water:

• Elevated bacteria levels due to runoff and warming ground temperatures
• Increased turbidity or cloudiness
• A rise in iron, manganese, or sulfur due to shifts in water table chemistry

Municipal Water Users: Heat Can Still Have an Effect

Even treated city water can experience seasonal changes. While municipal treatment plants maintain standards, heat can affect how water travels to and through the home.

Possible Symptoms:

• A chlorine or musty odor
• Discoloration from sediment stirred up in pipes
• Taste changes due to algae blooms in source water

Best Practices to Keep Summer Water Safe

Whether relying on well water or city water, there are several preventative steps homeowners can take to ensure clean, safe water all summer long.

Preventative Measures:

Test Water Regularly: At the start of summer and after major rain events or droughts

Install Proper Filtration: Use sediment filters, activated carbon systems, or UV disinfection where needed

Flush Faucets and Hoses: Remove stagnant water that may have built up in outdoor plumbing

Maintain Plumbing Fixtures: Check for leaks, corrosion, and pipe aging

Stay Hydrated with Filtered Water: Ensure drinking water is free of seasonal contaminants
