Various industrial processes use water that must be of an exact type of pH reading, and chemicals are then added to change the pH levels. This altered pH in the water is later discharged into sewage treatment plants and bodies of water. Other factors which may change the pH levels in bodies of water are associated with organic material present ...

A minor increase in pH levels can cause a oligotrophic (rich in dissolved oxygen) lake to become eutrophic (lacking dissolved oxygen). Even minor pH changes can have long-term effects. A slight change in the pH of water can increase the solubility of phosphorus and other nutrients – making them more accessible for plant growth ¹⁰.

pH is a measure of how acidic/basic water is. The range goes from 0 to 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base. pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.

There are a number of factors that contribute to the pH level in your tank including the trace mineral content, the type of substrate you use, and the chemical concentration in your tank water. If any of these things changes, it could lead to a change in the pH value of your tank water. Other things that might cause a change in pH include the ...

Unfortunately, not all water is pure and is rarely ever at this actual level. So why do the pH levels of water change? There are many contributing factors that can effect the acidity and alkalinity of water. The first and most prominent of these is the bedrock and soil composition in which the water is located.

Both sodium and calcium hypochlorite will have a minor affect on pH levels. Calcium hypochlorite is often used in treating potable water and as a means of disinfectant in water treatment plants. Both compounds are easily introduced into the body and can change the pH levels that can be measured by testing urine and saliva.

WHY CARE ABOUT pH? A quatic life is adapted to the natural pH levels in their bodies of water, and even slight changes in pH can have negative impacts on the health of the aquatic community. Moderate changes in pH can affect fish egg production, fish and insect gills, and amphibian populations.. A change in the pH of water can alter the behavior of other chemicals in the water.

The pH scale is logarithmic, so every one-unit change in pH actually represents a ten-fold change in acidity. In other words, pH 6.0 is ten times more acidic than pH 7.0; pH 5 is one hundred times mores acidic than pH 7.0. What causes the pH of a stream to vary? The pH of a body of water is affected by several factors.
