So, what does pH mean for water? Basically, the pH value is a good indicator of whether water is hard or soft. The pH of pure water is 7. In general, water with a pH lower than 7 is considered acidic, and with a pH greater than 7 is considered basic. The normal range for pH in surface water systems is 6.5 to 8.5, and the pH range for groundwater systems is between 6 to 8.5.
Email address: pH is used to measure the acidity of your swimming pool, and you need to maintain this pH level consistently within a pH range of 7.4-7.6. This ideal range is considered balanced for pool water, even though this range is technically on the basic side of the scale. Less than 7.4 is acidic, more than 7.6 is more basic.
