Murfreesboro Water Quality: Understanding Your Plumbing and Water Damage Risks

For homeowners in Murfreesboro, maintaining a healthy home often starts with understanding what flows through their pipes. Our local water, drawn from the East Fork of the Stones River and J. Percy Priest Lake, provides life to our community. But its unique characteristics, combined with Murfreesboro’s climate and geology, can pose specific challenges to plumbing systems and raise the risk of water damage over time. Here at Murfreesboro Water Damage & Restoration, we’ve personally seen how these factors contribute to everything from pinhole leaks to widespread mold issues in properties across Blackman, Downtown Murfreesboro, and near MTSU.

Murfreesboro’s Water: From Stones River to Your Tap

Our municipal water supply originates from two vital surface water sources: the East Fork of the Stones River and J. Percy Priest Lake. The Murfreesboro Water Resources Department (MWRD) and the Consolidated Utility District of Rutherford County rigorously treat this water, using processes like filtration, chlorination, and membrane filtration to ensure it meets federal drinking water standards. In fact, membrane filtration was specifically upgraded in 2021 at the Stones River Water Treatment Plant, effectively removing 100% of Cryptosporidium and particles larger than 0.1 microns.

However, “meeting federal standards” doesn’t always tell the whole story about the long-term health of your plumbing. Independent analyses indicate that while safe to drink, the water here contains certain elements that warrant attention.

The Silent Threat: How Water Chemistry Affects Your Plumbing

One significant characteristic of our area’s water is its moderate to elevated mineral content, commonly known as hard water. This isn’t just an inconvenience for soap lathering or spotted dishes. Over time, hard water minerals like calcium and magnesium contribute to scale buildup within your pipes, water heaters, and appliances. This accumulation reduces water flow efficiency, forces appliances to work harder, and ultimately shortens their operational lifespan, making them more prone to failure.

Beyond hardness, disinfection byproducts (DBPs) are a concern. These form when disinfectants, like the chlorine used in water treatment, react with organic matter present in the source water. Murfreesboro’s water has shown detectable levels of Total Trihalomethanes (TTHMs), including Bromodichloromethane and Chloroform, as well as Haloacetic Acids (HAA5 and HAA9). While these are within federal legal limits, independent health guidelines suggest these levels can be significantly higher than ideal; for instance, TTHMs were detected at 335 times EWG’s health guideline, and HAAs even higher. These compounds, over decades, can contribute to the degradation of plumbing materials, leading to an increased likelihood of leaks and pipe failures, particularly in older homes.

Plus, emerging contaminants like Per- and Polyfluoroalkyl Substances (PFAS), also known as “forever chemicals,” have been detected in our water supply. There are documented concerns about PFAS leaching from sites like the Middle Point Landfill into the Stones River and J. Percy Priest Lake, which have been identified as “threatened” waterways by
