Understanding pH and Its Impact on Drinking Water Quality


What is pH?

pH is a measure of the acidity or alkalinity of a water system, which is crucial in determining the quality of wastewater. It ranges from 0 to 14, with a pH of 7 considered neutral. Values below 7 indicate acidity, while those above 7 are alkaline. The pH scale is logarithmic, representing a ten-fold difference in acidity or alkalinity with each whole number change. Nutrients and compounds in the water can also affect the pH level.

How does pH affect drinking water?

The pH level of drinking water, just like in lakes, can have a significant impact on its quality for people. High or low pH levels can affect the taste of drinking water and foods, making it unpleasant to drink or consume.

Extreme pH levels can also cause chemical contaminants to be more prevalent in the water, which can be harmful to human health. To ensure safe consumption, it’s recommended to use filters to regulate the pH levels of drinking water.

What affects the pH of tap water?

Several factors, including the quality of the source and treatment processes used by local utilities, can influence the pH level of tap water. Groundwater sources tend to have higher alkalinity due to their contact with rocks and minerals containing calcium carbonate, which can affect the flower people receive. However, using a filter can help improve the quality of tap water by removing impurities and potentially harmful substances. Additionally, treatment methods such as chlorination and fluoridation can raise the acidity levels in drinking water, making it important to consider using a filter for improved water quality.

Drinking Water Quality

Drinking water quality standards set by regulatory agencies include guidelines for safe levels of contaminants such as lead, arsenic, and pesticides. However, these standards do not address changes in taste or odor caused by variations in pH levels.

Wastewater Treatment

Wastewater treatment plants closely monitor pH levels to ensure the quality of treatment and discharge into natural bodies of water. High or low pH levels in wastewater can disrupt biological processes needed for effective treatment, ultimately affecting the overall quality of the treated water.

Common Drinking Water pH Levels and Their Significance


The pH level is an essential factor that affects both its taste and health benefits. Different types of water have different pH levels, and understanding these levels can help you make informed decisions about the quality of your drinking water.

What is the pH Level of Water?

The pH level of water refers to its acidity or alkalinity. The scale ranges from 0 to 14, with 7 being neutral. A pH level below 7 indicates acidity, while a pH level above 7 indicates alkalinity. The ideal range for drinking water is between 6.5 and 8.5.

Common Drinking Water pH Levels

Regular tap water usually has a pH level between 6.5 and 8.5, which is considered safe for consumption. However, well water can have a lower pH level due to the presence of minerals such as iron or manganese in the soil.

If the well water’s pH level drops below 6.5, it can cause copper to leach into the water from pipes or plumbing fixtures that contain copper components like brass fittings or valves.

On the other hand, bottled waters may have varying ph values depending on their source and treatment process, with some having high ph levels.

Importance of Drinking Water’s PH Level

Drinking water’s pH level plays a crucial role in determining its taste and health benefits:

  • Taste: The ideal range for drinking water’s taste is between 6.5-8.5 due to its neutral level of acidity, which provides a pleasant taste without any metallic or sour aftertaste. This range is also reflected in the water’s ph values, with a low ph level indicating an unpleasant taste.
  • Health Benefits: Alkaline-based diets, which aim to increase the ph values in the body, are becoming increasingly popular as they are believed to provide numerous health benefits such as reducing inflammation in the body, improving digestion, boosting energy levels, and even optimizing water systems. 
  • To further enhance the benefits of alkaline-based diets, it is recommended to consume purified water or install a water filter to ensure that the water consumed has an alkaline ph level.

However, there isn’t enough scientific evidence supporting these claims yet; hence it’s essential to maintain a balanced pH level for drinking water.

Safe pH Ranges of Drinking Water

The Environmental Protection Agency (EPA) has set a standard range of 6.5-8.5 as the safe pH range for drinking water, which indicates a neutral level. Any value outside this range could indicate contamination or other issues with your water supply, and you should contact your local water authority immediately.

The Dangers of Acidic Water with a pH of Less Than 7


Water is essential for human life, and it’s important to ensure that the water we drink is safe and healthy. One crucial factor in determining water quality is its pH level. A pH level below 7 indicates acidic water, which can have several dangers associated with it.

Corrosion in Pipes and Fixtures

Acidic water with a pH level of less than 7 can increase the risk of corrosion in pipes and fixtures. Low pH levels cause the water to become more aggressive, leading to erosion and other damage to metal pipes and plumbing fixtures. This can result in leaks, clogs, or even burst pipes.

To prevent this from happening, homeowners should consider installing a neutralizing filter that raises the pH level of their tap water. These filters work by adding minerals like calcium carbonate or magnesium oxide to the water supply, which helps balance out the acidity.

Health Problems

Low pH levels in tap water can cause acid reflux and other health problems. When we drink acidic water, it can lead to an upset stomach or heartburn-like symptoms. Over time, this can cause more severe conditions like ulcers or even cancer.

It’s crucial to test your tap water regularly for its pH level if you experience any gastrointestinal issues after drinking your tap water. If you find that your tap water has low pH levels, switching to bottled alkaline or mineral-rich spring waters may be a safer option for your health.

Contamination in Lakes and Ponds

Acidic water with a high pH level can dissolve metals, leading to potential contamination in lakes and ponds. When rainwater falls on soil containing metals such as copper or lead, it dissolves them into solution form before flowing into nearby bodies of freshwater. However, if the water has a neutral level, the risk of metal contamination is significantly reduced.

If these bodies of freshwater have a naturally low pH level due to factors such as acid rain or volcanic activity, they become even more corrosive when combined with metal ions. On the other hand, bodies of freshwater with high pH levels can also become contaminated when exposed to metal ions. This contamination can make the water unsafe for drinking or aquatic life.

To prevent this from happening, homeowners should avoid pouring acidic substances like vinegar or lemon juice down their drains. These substances can cause low pH levels in the water supply and contribute to contamination over time.

Neutralizing Acidic Water

Neutralizing acidic water with baking soda or soda ash can help maintain a safe acidity level. Baking soda is an alkaline substance that neutralizes acid by reacting with it chemically. Soda ash works similarly but is more effective at raising the pH level of water.

Homeowners can add a small amount of baking soda or soda ash to their tap water supply to raise its pH level and make it less acidic. However, it’s important not to use too many of these substances as they can also have adverse effects on your health if ingested in large quantities.
