2000-4-20  Dolomite also slowly dissolves in the growing medium over time, helping to counteract the acidifying effects some fertilizers and/or irrigation water can have on growing medium pH. The need for new research on pH has been identified by industry as important due to observation of low pH in many soil and water samples.

Chapter 2 WATER QUALITY WHO

The effects of human activities on water quality are both widespread and varied in the degree to which they disrupt the ecosystem and/or restrict water use. Pollution of water by human faeces, for example, is attributable to only one source, but the reasons for this type of

Flow, dissolution, and precipitation in dolomite

with carbonate minerals of which over 50% is dolomite [Krauskopf, 1967]. [3] Groundwater quality and flow patterns can be strong-ly influenced by water-rock interactions in formations con-taining carbonate. Dissolution and precipitation are two dominant processes controlling groundwater chemistry and dynamics in these situations. Understanding

Flow, dissolution, and precipitation in dolomite

2003-6-6  [1] The evolution of hydraulic conductivity and porosity during the process of dedolomitization was examined in a series of laboratory experiments by analyzing the effects of concurrent dolomite dissolution and calcium carbonate precipitation. Linear flow experiments were performed in columns of crushed sucrosic dolomite by injecting different concentrations of HCl at various flow rates.

Aquarium Water Quality: Total Alkalinity and Hardness

Water passes through the rocks in the ground as it makes its way to rivers and lakes, and picks up minerals on the way. When limestone and dolomite dissolve in water, one half of the molecule is calcium or magnesium (the "hardness") and the other half is the carbonate (the "alkalinity"), so
