Increasing the concentration of some components in rainwater intensifies aggressive rainfall, further aggravating the degradation processes of soils, especially agricultural land. Thus, the type of rainwater in which predominantly strong mineral acids residues are predominant, could be called Acid. Rain water, in which the anionic species of strong acids are not predominant, but only those caused by the solubilization of carbon dioxide, we call it a Moderate, and the type of water called Amoniacal is the one where ammonia (NH3) is the basic component. Researching pluvial water scrubbing capacity, due to the storage of suspended minerals for a longer time, enables us to investigate the real causes that lead to silting of lakes and ponds or the clogging of adjacent fields. Thus, rainwater Acid of maximum concentration solubilizes the most powerful limestone rock. CO2 and NH3 are the main components that preserve the lime particle wash / hydration properties. With dilution of the mineral component of the rainwater, the lime wash activity is best preserved in Ammonia rain water.
