In air stripping processes, the groundwater pH may rise due to the loss of ,acidic, carbon dioxide through the air stripping. The increased pH causes precipitation and scaling of minerals such as calcium, magnesium, ,iron, and manganese. Injection of an acid solution may be needed to prevent the rise in pH and subsequent mineral precipitation.
