Water is essential for all life on Earth, but did you know that the quality of that water can have a significant impact on both our health and the environment? One crucial aspect of water quality often overlooked is its pH level.
pH is a measure of the acidity or alkalinity of water, and it plays a critical role in determining its overall quality. In this article, we’ll explore why understanding water pH levels is important and impacts everything from your daily life to the planet. So, let’s dive in and explore the world of water pH levels.
What is PH?
pH is one of the most important concepts in chemistry, as it measures the concentration of hydrogen ions in a liquid. A scale from 1 to 14 allows us to measure acidity or alkalinity, with 7 being neutral. Anything below 7 is an acid, and anything above 7 is an alkali – or base.
The pH should sit at 7 in pure distilled water, but any contamination or other substances may alter the pH balance.
When measuring pH levels in liquid solutions, it’s important to be aware that the concentration of hydrogen ions can be affected by various factors, including temperature changes and the presence of certain ions and molecules.
To get an accurate reading, a calibrated digital meter must often be used due to the dynamic nature of pH values.
Without knowing what kind of substance you are working with and its corresponding pH level, dangerous outcomes could occur if chemical reactions are mishandled or analyzed improperly.
Why Is PH So Important?
Water pH levels are critical to the health and balance of aquatic ecosystems, as it determines the amount of available nutrients, oxygen levels, and even the toxicity of chemicals. When water pH levels are off-balance, it can cause several problems for the plants, animals, and other organisms that live in and around the affected body of water.
One key reason why pH is so important is that most aquatic life forms have adapted to a particular pH range. When the pH level fluctuates outside of this range, it can cause various problems for the organisms living in the water.
For instance, when pH levels are too low or too high, aquatic creatures may be unable to digest their food properly, leading to malnourishment or even death.
The same is true for humans. When we drink water with an off-balance pH level, it can cause a variety of health issues. For instance, consuming acidic water regularly can cause tooth enamel erosion and other digestive problems.
How Do I Measure PH?
Measuring the pH of water samples is critical for organizations like the U.S. Geological Survey, which analyzes hundreds of thousands of water samples annually. Portable field pH meters are invaluable for analyzing and measuring pH levels at the sampling site.
These portable devices are designed to be used in tight, confined spaces, often outside in changing environmental conditions.
They feature a cup into which the sample is poured, and then a glass electrode connected to a retractable arm is placed into the sample to measure the pH level.
In more controlled lab settings, larger machines measure pH levels. These machines are much more accurate and feature adjustable arms, enabling the sensor depth to be adjusted just above or below the surface of the liquid being tested while also providing added protection from potential damage or contamination from extended exposure times.
Most importantly, though, these machines include digital readouts, which allow results to be recorded accurately and quickly with less potential for human error.
How Does PH Affect Water?
The pH of water is a significant factor in determining its quality and suitability. Generally speaking, higher pH levels make certain elements, such as minerals and metals, more available to the body.
This makes heavy metals more toxic when the pH is lower and less toxic when the pH is higher. Additionally, a high or low pH can indicate other contaminants or bacterial life in the water.
A much narrower range of acceptable pH levels exists for specific uses such as drinking water. Water that falls too far outside this range is likely unsafe for drinking without treatment to neutralize acidic or alkaline content within it first.
In either case, a person’s ability to effectively utilize water depends largely on how closely its pH aligns with certain standards of acceptability shown through extensive testing and research.
What To Do If the Ph Isn’t Right In My Water?
If your water’s pH levels are not optimal, it is important to take steps to correct the issue. First, it is important to identify what is causing the imbalance, as this will help you determine how to resolve the problem best.
The most common causes of pH imbalances are contamination from pollutants, over-aeration of groundwater, or runoff from agricultural activities.
If the source of the pH imbalance is identified, potential solutions for restoring balance include aeration, chemical treatments, and even adding minerals like calcium or magnesium.
In some cases, natural processes like photosynthesis and evaporation may be used to restore balance. In other cases, it may be necessary to use more extreme measures such as reverse osmosis filtration systems or water softeners.
Things That Effects Water PH
Water pH levels are an important factor in determining the overall health of aquatic ecosystems. The pH level of water is a measure of its acidity or alkalinity, and it can dramatically affect the types of organisms that live in the water.
Changes in pH can also affect how well aquatic plants and animals absorb essential minerals from the water. Many things affect ph, which is:
Carbon Dioxide and pH
The impact of carbon dioxide on the pH level of water is undeniable. Carbon dioxide is the most common cause of acidic water (¹⁵), with photosynthesis, respiration, and decomposition all contributing to pH fluctuations. The extremity and duration of the change depend on the alkalinity of the water.
However, there are usually noticeable diurnal variations (¹⁶). It is more prominent in environments where respiration and decomposition rates are high.
In addition to simply being present in a dissolved state like oxygen, carbon dioxide also can react chemically with water to form carbonic acid: CO2 + H2O <=> H2CO3.
This reaction leads to an acidic environment, which can have a detrimental effect on many aquatic species. As such, it is important to manage CO2 levels in bodies of water carefully to ensure the health and well-being of its inhabitants.
Temperature and pH
Temperature is also a major factor in water pH levels. Generally, cold-water species prefer slightly acidic waters (pH 6-7). Warmer water tends to become more alkaline, as microorganisms tend to consume carbon dioxide at higher temperatures.
This can be especially apparent in large bodies of water such as oceans and lakes, where warm surface layers are often more alkaline than colder, deeper layers.
Natural PH Influences
Natural pH influences play an important role in determining water’s overall acidity or alkalinity. Limestone can neutralize changes in radiation caused by acids or bases in water. Calcium carbonate and bicarbonates keep water close to a neutral pH. These minerals in soil increase nearby carbonate levels and can make the water slightly basic.
Rainwater is usually slightly acidic, with a pH of around 5.6, before pollutants enter our atmosphere. Many things, like volcanic ash and bacteria, can change the pH of rain and water bodies.
Environmental changes can alter the pH levels of water, becoming more acidic or basic due to geological and meteorological factors and new elements introduced to the environment.
Man-Made pH Influencers
Many people know the dangers of acid rain and how it can damage ecosystems and even human health. However, few are aware of the human-influenced fluctuations in pH levels that can occur. Anthropogenic causes of pH fluctuations are usually related to pollution.
Acid rain is one of the best-known examples of human influence on water pH. Any precipitation with a pH level of less than 5.0 is known as acid rain ²¹.
When these acids come into contact with water, they cause a decrease in their pH level. The rain gets more acidic when it mixes with chemicals in the air.
Acid rain can come from many sources like mining, smelting, coal burning, and cars, making it hard to pinpoint its origin. But no matter where it originates, the impacts on ecological systems and human health are clear.
