what is good drinking water ph

Water pH plays a crucial role in our health and hydration. It affects how water tastes, how it interacts with our body, and even its ability to clean and nourish. So, what is pH? In simple terms, pH measures how acidic or alkaline water is. This scale ranges from 0 - 14, with 7 being neutral. Below 7, water is acidic. Above 7, it's alkaline.

When we talk about drinking water, pH matters a lot. It can influence the water's taste and, more importantly, our health. The proper pH level in drinking water can ensure it's safe and beneficial for our body's needs. Let's dive into what makes good drinking water pH and why it's essential.

The Science of pH

pH scale

Understanding the pH scale is like learning a new language—the language of water. This scale, which ranges from 0 to 14, tells us if water is acidic (below 7), neutral (exactly 7), or alkaline (above 7). Each point on the scale indicates a tenfold change in acidity or alkalinity. For instance, water with a pH of 6 is ten times more acidic than water at 7.

Measuring pH isn't just for scientists. It's something water quality experts do to ensure our drinking water is just right. They use special tools, like pH meters or litmus paper, to determine where water lands on the pH scale.

Why does this matter? Because the pH level of water can affect everything from its taste to how well it supports our body's natural functions. It can even influence how effectively water carries minerals and nutrients. So, knowing the pH of your drinking water isn't just interesting science—it's key to understanding its quality and impact on health.

Health Implications of Water pH

Water pH isn't just a number. It has real effects on our health. Let's break down what happens with different pH levels in water.

Acidic Water and Health

Drinking water with a low pH, meaning it's acidic, can be a concern. Acidic water may corrode pipes, leading to metals like lead or copper leaching into your water supply. This isn't just bad for your plumbing—it can affect your health. Consuming high levels of these metals can lead to serious health issues.

Alkaline Water: Pros and Cons

On the flip side, alkaline water, with its high pH, is often touted for health benefits. Some say it can help neutralize acid in the bloodstream, improving metabolism and energy. However, it's not all clear-cut. Drinking too much alkaline water might upset the body's natural pH balance, potentially leading to digestive issues or affecting how well your body absorbs nutrients.

Water pH and Body Balance

Our bodies have a slightly alkaline pH level. Drinking water that's close to neutral helps support this balance. It's like giving your body the right fuel—it can help everything run smoothly, from digestion to detoxification.

In essence, the pH of the water we drink can influence our overall health in several ways. It's not just about quenching thirst; it's about supporting our body's natural balance and function.

Ideal pH Range for Drinking Water

Finding the sweet spot for drinking water's pH isn't just guesswork. It's guided by science and health standards. Authorities like the Environmental Protection Agency (EPA) weigh in on this, aiming to keep our water safe and healthy.

What the Experts Say

The EPA suggests the ideal pH for drinking water is between 6.5 and 8.5. This range is considered safe and palatable, meaning it tastes good too. 

The Optimal pH Balance

So, why this range? Water with a pH between 6.5 and 8.5 strikes a balance. It's mild enough to be gentle on our digestive system and support our body's pH balance. Yet, it can also minimize corrosion in pipes, which can introduce harmful metals into our water.

Moreover, water within this pH range tends to taste better. Ever notice a slightly bitter or metallic taste in water? That can happen when the pH is off. Staying within the ideal range means the water is more likely to taste clean and refreshing.

In short, the ideal pH range for drinking water serves a dual purpose: it safeguards our health while ensuring the water is pleasant to drink. By adhering to these guidelines, water providers help ensure that what comes out of our tap is safe and enjoyable to consume.

Factors Influencing Water pH

The pH of drinking water isn't set in stone. It can vary, influenced by both the natural world and human activities. 

Natural Factors

The land your water travels through plays a big role. Water picks up minerals and compounds from soil and rocks, which can either raise or lower its pH. For example, water moving through limestone (which contains calcium carbonate) tends to be more alkaline.

Seasonal Changes

Seasons also leave their mark. Rainfall patterns, snowmelt, and even temperature can affect water pH. More rain might mean more acidic water, as rainwater absorbs CO2 from the air, forming a weak acid.

Human-Made Factors

water pollution


Industrial emissions, agricultural runoff, and even urban wastewater can introduce substances into water sources that significantly alter pH. Acids from rain, farming chemicals, and city waste can make water more acidic.

Water Treatment Processes

Conversely, water treatment plants work hard to correct these variations. They add chemicals to neutralize acidity or alkalinity, aiming to bring water within the safe and palatable pH range. This careful balancing act ensures that the water reaching our homes meets health standards.

Both natural and human-made factors mean that water's pH can be a moving target, requiring constant monitoring and adjustment. It's a testament to the efforts to ensure our drinking water supports our health and well-being.

Adjusting Water pH

Sometimes, the water that reaches us isn't quite at the ideal pH. But don't worry—there are ways to adjust it, whether it needs a nudge up or down the pH scale. Let's explore how we can bring water back into balance.

Increasing Water pH

Alkaline Filters

These filters add minerals to the water, nudging its pH higher. They're a go-to for making water more alkaline, which can be especially helpful if your water is naturally acidic.

Water Ionizers

Ionizers electrify the water, separating it into acidic and alkaline streams. The alkaline water is what you drink, and it's higher in pH. It's a tech-savvy way to get your water just right.


Simple additives, like baking soda, can raise water's pH. It's a straightforward method that adds alkalinity to water, making it less acidic.

Decreasing Water pH

Reverse Osmosis

This filtration removes minerals and impurities, often lowering the water's pH. It's effective for dealing with overly alkaline water, making it closer to neutral.

Water Distillers

Distillation purifies water through evaporation and condensation. This process can also remove elements that make water alkaline, reducing its pH.


Just as you can add substances to make water more alkaline, you can also add acidifiers, like citrus juice, to reduce the pH. It's a simple fix for slightly alkaline water.

Adjusting the pH of your drinking water can make it healthier and more enjoyable. Whether using advanced technology or simple household items, it's all about finding the best balance for you.
