Does Your Tap Water Have pH Problems?
Understanding the pH of your tap water is not just a matter of curiosity—it’s a vital step in safeguarding your health, enhancing your water quality, and prolonging the life of your plumbing and appliances. The pH level can significantly affect the taste of your drinking water and the ability for your body to absorb essential nutrients. By regularly testing your tap water, you can ensure a perfectly balanced pH, which is key for promoting your well-being and successfully maintaining your home. Don’t leave it to chance; make informed choices for both your health and your environment by knowing what is in your water supply!
Measuring the pH of Tap Water
Understanding the pH of your tap water is crucial for both health and maintenance reasons. Ideally, water should have a neutral pH of around 7. However, water classified as acidic has a pH below 7, while alkaline water has a pH above 7. The Environmental Protection Agency (EPA) considers a pH range of 6.5 to 8.5 as acceptable for drinking water supplies.
Across the U.S., water pH levels vary based on geographic location, water source, and treatment processes. Some areas naturally have more acidic water due to the surrounding geology, while others tend to have alkaline water because of minerals present in groundwater or surface sources.
The EPA recommends that public water systems keep a pH level of 6.5 to 8.5, but these levels arenot regulated in any way. Low pH water is considered a “secondary” water contaminant, but theeffects of acid water go beyond taste. It can hit you hard in the wallet, as well.
Possible Causes of pH Variations in Tap Water:
- Source Water: The pH of tap water can fluctuate based on whether it originates from groundwater, reservoirs, rivers, or imported supplies.
- Water Treatment: The addition of chemicals like lime or sodium carbonate during the treatment process helps stabilize pH and prevent pipe corrosion.
- Water Pumps and Distribution Systems: Water pumps used in municipal distribution systems can introduce variations in pH due to mechanical processes and pipeline conditions.
Monitoring pH Levels in Your Tap Water
Water agencies across the U.S. utilize chemical treatments, such as caustic soda and lime, to effectively manage and regulate pH levels and alkalinity in drinking water. This critical process is a key component of corrosion control strategies, reducing the risk of harmful metal leaching into the water supply.
What a Low pH of Tap Water Means for a Household
A low pH in tap water means that the water is acidic (pH below 7). Acidic water can present several challenges for households, particularly in regions with naturally soft water or where acidic rain impacts local water sources. If left unaddressed, acidic water can cause significant damage to plumbing systems, impact water fixtures and appliances, and even pose potential health concerns.
Key issues related to acidic water include:
- Plumbing Damage: Acidic water can corrode pipes, leading to leaks and costly repairs.
- Health Risks: Acidic water may leach metals like copper and lead from pipes, potentially contaminating drinking water.
- Aesthetic Issues: Households may notice stained sinks and tubs, unusual water colors, and an unpleasant metallic or sour taste.
- Appliance Wear and Tear: Water heaters, dishwashers, and washing machines may experience premature breakdowns due to internal corrosion.
Signs Your Home Has Acid Water
If your home’s tap water has a low pH, you may notice the following warning signs:
- Blue/green stains in sinks, tubs, and other fixtures due to copper pipe corrosion.
- Rust stains in fixtures, especially if your home has iron pipes.
- Low water pressure, potentially caused by corroded pipes narrowing over time.
- Metallic or sour taste in drinking water due to dissolved metals.
- Malfunctioning appliances, such as water heaters, washing machines, and dishwashers, as acidic water causes internal damage.
- Skin and hair issues, similar to the effects of hard water, as acidic water can be harsh on your body.
Sources of Acid Water in U.S. Tap Water
Several environmental and human-made factors contribute to acidic water conditions:
- Groundwater Composition: Some regions rely on groundwater as a primary drinking water source. Unlike limestone, which neutralizes acidity, granite-based geological formations do not, leading to naturally lower pH levels.
- Acid Rain: Industrial pollution, vehicle emissions, and other environmental factors can contribute to acid rain, which infiltrates groundwater basins and surface water reservoirs, affecting pH levels.
- Agricultural Runoff: Fertilizers and pesticides can introduce acidic compounds into water supplies, affecting both surface and groundwater sources.
Impact of Acidic Water on Household Plumbing and Appliances
When tap water has a low pH, it can cause extensive damage to household plumbing and water-related appliances:
- Pipe Corrosion: Acidic water slowly eats away at metal pipes, leading to leaks, pinhole fractures, and structural weaknesses. As pipes corrode, harmful metals like copper, lead, and iron can dissolve into the water, creating serious health concerns.
- Staining and Water Discoloration:
- Blue/green stains in sinks, tubs, and toilets indicate copper pipe corrosion.
- Rusty water may appear if iron pipes are corroding due to acidic conditions.
- White or yellow water can indicate dissolved solids reacting with plumbing materials.
- Reduced Appliance Lifespan: Appliances that rely on water, such as water heaters, dishwashers, and washing machines, can suffer from premature wear. Corrosion inside these systems may cause leaks, malfunctions, and increased maintenance costs.
Addressing acidic water issues early can prevent costly repairs and improve water quality in the home.
Effects on Water Taste and Quality from Acid Water
Acidic water can alter the taste and safety of drinking water, affecting households across the U.S.:
- Sour or Metallic Taste: Water with a low pH often tastes unpleasant due to increased levels of dissolved metals like copper and iron.
- Increased Contaminant Levels: As acidic water corrodes pipes, it can introduce metals and other harmful substances into the drinking water supply. This can pose serious public health concerns, particularly in areas with older infrastructure.
- Potential Impact on Health: While slightly acidic water itself is not inherently dangerous, long-term exposure to heavy metals leached from plumbing can cause health issues. Water treatment devices, such as pH neutralizers, can help mitigate these risks.

Are There Benefits of Alkaline Water?
The benefits of water with a level above a pH of 7 are well-documented, but not scientifically proven.
In fact, alkaline water can contribute to scale buildup in your household plumbing and bitter tasting coffee. This kind of water has been marketed to consumers for years, but the evidence that any consumption of this type of water is beneficial from a health standpoint is a pseudoscience.
You’ve probably heard the hype about alkaline water benefits. Is there a correlation between alkaline water and good health? It seems like every other year there’s a new trend in water.
By nature, regular tap water has a neutral pH. You might remember testing different liquids inchemistry class by dipping a strip in them to determine their pH — you can get those same strips at a hardware store to test your water to see what kind of balance your tap water has, but chancesare it will fall around 7, which is neutral.
Myths that involve alkaline water include:
- Health benefits mixed with lemon
- Anti-aging claims
- Illness prevention
Is Culligan Filtered Water Alkaline?
Culligan water is no more or less alkaline than your typical bottled water you’ll find in stores.
Our bodies are designed to function effectively with plain, neutral pH water. They’re designed to find their own balance, and while many health trends come and go, the biggest takeaway is that simple hydration is the key. The more water you drink (to a point) the healthier you’ll be, whether that water is slightly more alkaline, or slightly more acidic.
Want to experience all the benefits of alkaline water? You’ll likely be just as well off saving your money and drinking fresh, filtered tap water. As long as the water you’re drinking is free from harmful contaminants, you’ll benefit from getting your daily recommended ounces (the rule of thumb is at least 64 ounces per day, or eight, 8-ounce glasses) of water.
