Gardnerville & Minden’s Home for Water Treatment

Yes, the tap water in Gardnerville and Minden is generally considered safe to drink and meets all federal and state drinking water standards. The Town of Minden and Gardnerville Water Company supply water to these communities, primarily from high-quality underground aquifers in the Carson Valley. According to recent Water Quality Reports, there were no violations for regulated contaminants. However, trace levels of substances such as nitrate, arsenic, and fluoride have been detected—each remaining well within safe limits set by the EPA. Disinfection byproducts like total trihalomethanes (TTHMs) and haloacetic acids (HAA5) may be present in small amounts but also comply with federal regulations. Individuals with specific health concerns or compromised immune systems should consult with a healthcare provider for personalized advice.

Yes, the water in Gardnerville and Minden is classified as hard to very hard, with mineral concentrations—especially calcium and magnesium—typically ranging between 150 to 300 parts per million (ppm). This level of hardness can cause scale buildup on faucets and fixtures, reduce the efficiency of water heaters, and make soaps and detergents less effective. Many local residents use water softeners to protect plumbing systems and improve water quality in their homes.

As of the most recent testing available, PFAS compounds (per- and polyfluoroalkyl substances) have not been detected at levels exceeding EPA advisory guidelines in the Gardnerville or Minden water supply. However, PFAS are considered emerging contaminants, and the EPA is working to finalize stricter regulations for compounds like PFOA, PFOS, and PFHxS. While local water providers continue monitoring, concerned residents may benefit from installing a certified filtration system—such as a reverse osmosis unit—to reduce potential PFAS exposure.

Minden's most recent water quality report does not report on fluoride levels. Gardenerville's 2021 water quality report reported levels of fluoride reaching 1.6 ppm, however, the most recent reports do not mention fluoride.

The tap water in Gardnerville and Minden comes from local groundwater wells that draw from deep, protected aquifers beneath the Carson Valley. These aquifers are recharged by snowmelt from the Sierra Nevada and seasonal rainfall, making the region less dependent on surface water sources. Water is treated with a combination of disinfection, filtration, and quality monitoring to meet state and federal safety standards.

Because water in the Carson Valley region is hard to very hard, a Culligan water softener can help prevent mineral buildup on pipes and appliances, reduce soap scum, and improve overall water feel and performance. To address taste and safety concerns—such as trace arsenic, chlorine byproducts, or potential PFAS, many homeowners opt for a reverse osmosis filtration system. The most comprehensive solution includes both softening and filtration, ensuring cleaner, better-tasting water throughout the home while protecting plumbing systems and enhancing appliance longevity.
