    Statewide pH 2012-2015

    What is pH?

    Substances can be acidic, basic, or neutral. This is described by pH. It is measured on a scale of 0-14, with 0-7 being acidic, 7 neutral, and 7-14 basic. The pH scale is compared to the Richter scale, meaning that one change in pH, for example 6.0 to 7.0, represents a tenfold increase.

    The pH of water bodies is an indicator of the health of a system. Rain typically hits the earth as 5.5 pH, but is buffered by Utah's soils and aquatic plants to become more neutral.

    Utah Water Watch volunteers have collected nearly 1250 Tier 1 stream pH measurements since 2012. That's almost one pH measurement collected somewhere in Utah each day for the last four years. Great Work!
