What is pH and why does it matter for your water?

What is pH?
pH is a measurement of electrically charged particles in a substance. It indicates how acidic or alkaline (basic) that substance is. The pH scale ranges from 0 to 14:
  •          Acidic water has a pH lower than 7. The most acidic substances have a pH of 0. Battery acid falls into this category.
  •          Alkaline water has a pH of 8 or above. The most alkaline substances, such as lye, have a pH of 14.
  •          Pure water has a pH of 7 and is considered “neutral” because it has neither acidic nor basic qualities.

Freshwater pH varies across the world depending on weather patterns, human activity, and natural processes.
Water with a very low or high pH can be a sign of chemical or heavy metal pollution.
Water that doesn’t fall in the “safe” pH range of 6.5 to 8.5, particularly if it’s alkaline, isn’t necessarily unsafe. However, very alkaline water can have an unpleasant smell or taste, and it can also damage pipes and water-carrying appliances.

Acidic water with a pH of less than 6.5 is more likely to be contaminated with pollutants, making it unsafe to drink. It can also corrode or dissolve metal pipes.

So what are the pH levels of the things we drink

Above are some commonly found brands that promote having a certain pH level. Also for some example of other drinks and common house hold items; apple juice 3, orange juice 3.5, coffee 5.5, milk 6.2, baking soda 8.5, soapy water 10, bleach 12.

Alkaline water has become a popular drinking water choice over the past few years. Some people say that drinking slightly alkaline water with a pH between 8 and 9 can improve your health. They say it may make you age more slowly, maintain a healthy pH in your body, and block chronic disease like cancer.

Despite the many health claims made by alkaline water drinkers and sellers, there’s little to any scientific evidence that alkaline water is healthier than other kinds of drinking water.
But there are a few studies suggesting alkaline water may benefit the health of people with certain medical conditions, such as acid reflux, high blood pressure, diabetes, and high cholesterol. High alkaline, electrolyzed water may also be helpful after dehydration caused by exercise.

So in conclusion while there is some research about the benefits to drinking water with a slightly higher than neutral pH, it wont actually harm you either to be consuming water slightly below or above the neutral 7 pH.
