Norfolk County’s Rising Groundwater Crisis: How Climate Change Is Causing Chimney Foundation Leaks in Massachusetts Homes

Norfolk County homeowners are facing an unprecedented challenge that’s emerging from beneath their homes: rising groundwater levels that are increasing in fall and early winter due to projected increases in precipitation, while creating unexpected pathways for water damage through their chimney foundations. Over the last 50 years, groundwater levels have actually been going up in Massachusetts, mostly attributed to more intense and frequent rainstorm events.

This environmental shift is creating a perfect storm for chimney-related water damage that many homeowners aren’t prepared for. When the water table rises, water can come up through the bottom of chimneys that are open to the ground, flowing out through clean-out doors in basements.

Understanding the Climate Connection

Climate change threatens drinking water supplies, especially in Middlesex, Norfolk, and Plymouth Counties, but the impact extends beyond water availability. Groundwater levels have increased over the last 50 years, and over the next 50 years, groundwater recharge is projected to increase in the late fall and early winter with increased precipitation.

However, the seasonal patterns are becoming more extreme. The increase in the amount and intensity of precipitation will increase flood risk in all communities studied, and in coastal areas, increased precipitation may combine with higher groundwater tables and sea levels to exacerbate damage.

How Rising Groundwater Affects Chimney Foundations

Traditional chimney construction often includes a foundation that extends below ground level, creating potential entry points for groundwater. Water can enter at the chimney base or from ground level or below, and ground and surface runoff often enter the base of a chimney that extends below ground.

Groundwater entering a basement clean-out box indicates poor exterior drainage or high water table. The problem becomes particularly acute because water typically starts coming in a day or two after heavy rains and will continue for two, maybe three days, with water visibly pouring into clean-out areas.

A chimney that sits outside the home’s foundation is built on its own footing and resembles a mini-basement, making it similarly susceptible to seepage problems that will eventually produce water in the adjoining basement or crawl space.

Warning Signs for Norfolk County Homeowners

Homeowners should watch for several key indicators of groundwater-related chimney foundation issues:

• Water pouring into a basement, coming out of the chimney cleanout during heavy rainstorms
• Water continuing to pour out of clean-out boxes long after rain has stopped, indicating groundwater intrusion
• Water running unchecked into the fireplace and walls beside and beneath it when chimney bricks are cracked or mortar is eroding
• Increased groundwater levels resulting in subsurface flooding of basements and other infrastructure

Annual average groundwater recharge is projected to decrease by approximately 18 percent towards the end of the century, making it important for counties to balance drinking water demand with projected decreases in groundwater availability. However, the immediate concern for homeowners is managing the current increase in groundwater levels.
