AbstractThe Incident Command Tool for Drinking Water Protection (ICWater) provides real‐time assessments of the travel and dispersion of contaminants in streams and rivers. It is structured around the RiverSpill model which has been enhanced to make use of the 1:100 000 scale National Hydrography Dataset Plus, Version 1.0 (NHDPlusV1). NHDPlusV1 is a hydrologically connected river network that contains over 3 million reach segments in the United States. This allows for both downstream and upstream tracing (which serves in forensic analysis). Mean flow and velocity have been calculated by the US Geological Survey (USGS) and Environmental Protection Agency (EPA) for each reach. These mean values are updated by flow from web accessible real‐time gauging stations. Example databases available within ICWater include: dams, reservoirs, water supplies, gauges, municipal and industrial dischargers and transportation networks. A contaminant database is also included which identifies biological, chemical and radiological contaminants and their toxicities. Navigating the river network upstream coupled with mass‐balance calculations from breakthrough curves allows for backtracking of the contamination to determine the origin and source strength.

AbstractMany countries have applied many measures, including preventing inappropriate activities in areas where drinking water is abstracted to protect drinking water resources. However, reaching good water quality based on human health has not been achieved in drinking water basins. Drinking‐Water Protected Areas Determination has been defined as a powerful protection method to restrict inappropriate activities affecting water quality and quantity. These areas are determined based on basin properties to provide sustainable drinking water management. This study aims to present a framework for drinking water protection by giving methodological study steps. Strengths, deficiencies and inadequacies in drinking water protection practices were shown by examining the implementations of Turkey and European Union member countries. Thus, by adding new methods to these applications, a standard approach was created to be applied to each different drinking water basin.

Abstract: This study aims to determine the application of product quality standards for refilling drinking water in the East City of Gorontalo City and to find out the form of legal protection for consumers in the use of drinking water depots. The researcher uses a type of normative research that includes legal principles, legal systematics and legal comparisons and is supported by empirical research through primary data sources, namely data based on information obtained directly at the research location. The results showed that the fulfillment of the Quality Standards for Drinking Water Depots in Gorontalo City was not fully appropriate, one of which was in fulfilling the certification issued by the local government in ensuring hygiene and sanitation at least once a year. The form of legal protection for consumers is carried out by the Health Service in supervising and applying administrative sanctions to the management of drinking water depots.Keywords: Legal Protection, Consumers, Water Depot.
