Study of Groundwater Vulnerability to Contamination in Part of the Klaten District Area, Central Java-Indonesia

Water demands and risks of groundwater pollution in the Klaten District consistently increase as the human population grows over the years. This study aimed to examine the intrinsic and specific groundwater vulnerability levels (low, moderate, high) and analyze the spatial distribution and degree of...
