One of the main questions about travertine springs is their origin, as well as the secondary processes that have ch...
Corrosion and scaling in drinking water sources can lead to economic and health damages. These processes produce by-products in distribution systems, reduce chemical water quality, and are the cause of health issues among consumers. The aim of this study was to evaluate the corrosion and scaling potential of water supply sources of Marivan villages, Iran. In total, 106 water samples were collec...
The Great Artesian Basin (GAB) underlies about one fifth of mainland Australia.
