Karen C. Rice Owen P. Bricker 1989 <p>All water that reaches watershed systems comes directly or indirectly from precipitation. Normally, this water contains very small amounts of dissolved solids and is only slightly acidic. As a result of chemical reactions in watersheds, however, stream water generated from precipitation normally is less acidic and contains larger concentrations of dissolved solids than does the precipitation falling onto the watershed.</p> application/pdf 10.1021/es00181a001 en ACS Publications Acidic deposition to streams: A geology-based method predicts their sensitivity article
