WebpH is a measure of acidity or alkalinity of water on a log scale from 0 (extremely acidic) through 7 (neutral) to 14 (extremely alkaline). It is the negative base-10 log of the hydrogen ion (H+) activity in moles per litre. Hydrogen ions predominate in waters with pH less than 7; hydroxyl ions (OH-) predominate in waters with pH greater than 7.

WebpH is a measure of hydrogen ion concentration and indicates the relative acidity or alkalinity of water. pH significantly higher or lower than the neutral value of 7 is deleterious to most aquatic life. pH measurements outside of a certain range may indicate problems such as excessive decay of organic matter (eutrophication) or acid mine drainage. Web1. Phosphates are usually present in the environment in low concentrations, which limits plant growth. High phosphate levels can come from man-made sources such as septic systems, fertilizer runoff and improperly treated waste-water.
