Landfills are one of the groundwater pollution sources in the world. This study focuses on two landfills; the first has a lining system and the second does not have lining system to assess the generated leachate quantity and percolation to the groundwater aquifer at a specific sites, using the approaches of (i) the Hydrologic Evaluation of Landfill Performance model (HELP) and (ii) the water balance method (WBM). Furthermore, landfill components were analyzed to study their influence on the quantity of percolated leachate to groundwater. The Geographic Information System (GIS) was used as a...

Worldwide, many lives are lost because of the spread of infections in health facilities. Microbial organisms spreading in everything around us (air, water, food and inanimate surfaces). Most of these infections can be prevented by well-established processes for decontamination and cleaning of soiled instruments. This study aimed to evaluate the environmental infection control (EIC) measures in the general ICUs in Gaza. A total of 196 microbiological samples for air, water, and inanimate surfaces were surveyed. Both ambient air and inspiratory air from mechanical ventilator machines were...
