pH and Water

Resource: Water Science School - pH and Water (USGS)

pH is the measurement of water acidity. pH ranges from 0 to 14 with 7 being a neutral solution of pure water at 25 °C. A pH value less than 7 is acidic and a value greater than 7 is basic. Measuring the pH helps determine the solubility of nutrients, such as nitrogen and phosphorus, and heavy metals. A constituent can have differing effects on aquatic life depending on the amount that can be dissolved in the water (its concentration).
