Water-use estimates by county are available for the United States, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands which support the State-level water-use estimates published in USGS Circular 1441, Estimated Use of Water in the United States in 2015. Publication data files for other 5-year reports are also available.
The Global Surface Water Explorer is a simple web-mapping tool that shows all of the water datasets and allows users to navigate the globe visualizing the water datasets without installing any software. It also allows users to view the complete history of water detections over the 37-year period by clicking on the map. The tool is intended as a data viewer and does not provide any analytical features - if you would like to do your own analysis on the data then access the data using Data Download or Google Earth Engine.

Currently all of the mapped datasets are available to download (i.e. occurrence, change, seasonality, recurrence, transitions and maximum extent). The water history datasets and metadata datasets will be made available in the near future.
The Global Surface Water data are available to download in tiles 10x10 from the map shown below. Click on the tile to show a list of the available datasets. Each one of these datasets is a hyperlink to the *.tif file.
The full global surface water datasets can be downloaded by using this Python 2 script or using this Python 3 script . The zip file contains the Python script and a set of instructions for using it. An handy alternative way to download this data is to use the following script wrote by Petr Tsymbarovich, available at this GitHub link.
It is possible to download all the Global Surface Water Datasets via FTP using the Filezilla Client . Once downloaded and installed Filezilla, write in the Host field the link jeodpp.jrc.ec.europa.eu and then browse to GSWE folder to get all the Global Surface Water Explorer data. Alternatively, it is possible to get the data using the link -opendata/GSWE/
Each of the downloadable files contains a colormap which will display the files in desktop GIS tools (such as QGIS or ArcGIS) using the symbology that has been used in the Global Surface Water Explorer. However, these colormaps do not contain the labels for the values. These can be added to the files by using the following symbology files. For instructions on how to use these files see the 'Using Symbology Files' section of the Data Users Guide.
Water is at the core of sustainable development. Water resources, and the range of services they provide, underpin poverty reduction, economic growth and environmental sustainability. From food and energy security to humanand environmental health, water contributes to improvements in social wellbeing and inclusive growth, affecting the livelihoods of billions.
Behind the global headline figures, considerable disparities in access remain between countries. While many developed countries have now achieved universal access, coverage with safely managed drinking water sources varies widely in developing regions. The lowest levels of coverage are found in the 46 countries designated as the Least Developed Countries by the United Nations, particularly those in sub-Saharan Africa. In 36 countries, less than half of the population used safely managed drinking water services in 2020.
Since 1990, WHO and UNICEF have tracked progress on global water and sanitation goals through the Joint Monitoring Programme for Water Supply, Sanitation and Hygiene (JMP). The JMP monitors trends in coverage; helps build national monitoring capacity in developing countries; develops and harmonises questionnaires, indicators and definitions to ensure comparability of data over time and among countries; and informs policymakers of the status of the water supply and sanitation sector through annual publications. The JMP draws guidance from a technical advisory group of leading experts in water supply, sanitation and hygiene, and from institutions involved in data collection and sector monitoring. Further information about the JMP and its methodology can be found at the JMP website.
Citizens, nature and industry all need clean rivers and lakes, groundwater and bathing waters. The Water Framework Directive is about getting polluted waters clean again and ensuring clean waters are kept clean.
Since 2000, the Water Framework Directive has been the main law for water protection in Europe. It applies to inland, transitional and coastal surface waters as well as groundwaters. It ensures an integrated approach to water management, respecting the integrity of whole ecosystems, including by regulating individual pollutants and setting corresponding regulatory standards. It is based on a river basin district approach to make sure that neighbouring countries manage the rivers and other bodies of water they share.
The key objectives of the WFD are set out in Article 4 of the Directive. It requires Member States to use their River Basin Management Plans (RBMPs) and Programmes of Measures (PoMs) to protect and, where necessary, restore water bodies in order to reach good status, and to prevent deterioration. Good status means both good chemical and good ecological status.
The Directive covers surface water pollutants in two ways: by identifying and regulating those of greatest concern across the EU (the priority substances listed in Annex X to the WFD) and by requiring Member States to identify substances of national or local concern (river basin specific pollutants included by Member States in their River Basin Management Plans).
The Enforcement and Compliance History Online (ECHO) system incorporates Public Water Systems data from EPA's Safe Drinking Water Information System (SDWIS) database. These downloads provide national data for key EPA/State Drinking Water Dashboard metrics, which are some of the SDWIS data elements most commonly used in the enforcement and compliance program.
The Safe Drinking Water Information System (SDWIS) contains information on public water systems from the Public Water System Supervision (PWSS) Program, including monitoring, enforcement, and violation data related to requirements established by the Safe Drinking Water Act (SDWA).
Address (Cities Served, State, State Name, and State Code) - City(ies) and state(s) where the system provides drinking water. In some cases, the address may indicate the mailing address of the system owner. For systems in Indian Country, the state is the state primarily served by the system, if EPA can determine that from available locational data, or else the mailing address state of the system owner. Note: Data on areas served may be incomplete and have not been quality assured.
CONTAMINANT_CODE (AKA CONTAMINATION_CODE) - A code value that represents a contaminant for which a public water system has incurred a violation of a primary drinking water regulation. A full description of the codes can be accessed in the SDWA_REF_CODE_VALUES.csv.
FACILITY_DEACTIVATION_DATE - The date the facility was deactivated (no longer actively serving water) or removed from federal oversight because it no longer met SDWA criteria as a public water system (MM/DD/YYYY format).
FILTRATION_STATUS_CODE - A code reported by the state to indicate whether a non-emergency surface water source or a non-emergency ground water under the influence of surface water source is required to install filtration by a certain date or is successfully avoiding filtration.
IS_SOURCE_IND - Indicates whether the water system facility is designated a source (either a Consecutive Connection (CC), Infiltration Gallery (IG), Intake (IN), Non-piped (NP), Roof Catchment (RC), Reservoir (RS), Spring (SP), Well (WL), or Non-piped non-purchased (NN)).
PRIMACY_TYPE - Indicates whether the water system is regulated by a state, tribal, or territorial primacy program. Note that EPA direct implementation programs, except for Wyoming, are tribal primacy programs.
PWS_TYPE_CODE/PWS_TYPE_SHORT - Indicates the type of public water system (PWS). A public water system is a system for the provision to the public of piped water for human consumption, which has at least 15 service connections or regularly serves an average of at least 25 individuals at least 60 days out of the year. PWS_TYPE_SHORT indicates whether a system is Community or Non-Community. Possible values for PWS_TYPE_CODE include:
SUBMISSION_STATUS_CODE - Code that indicates whether an active water system was reported, rejected, or not reported during the recent inventory submission. This field is not applicable to inactive water systems. Generated by ODS.
WATER_TYPE_CODE - Character code identifying the type of water source. Ground water (GW), Surface water (SW), Ground water under the influence of surface water (GU). See the Water Topics page on the EPA website for full definitions of these terms and more.
Abstract:The importance of water security has gained prominence on the international water agenda, but the focus seems to be directed towards water demand. An essential element of water security is the functioning of public organizations responsible for water supply through direct and indirect security approaches. Despite this, there has been a tendency to overlook the water security strategies of these organizations as well as constraints on their operation. This paper discusses the critical role of water supply in achieving sustainable water security and presents two case studies from Central Asia on the management of water supply for irrigated agriculture. The analysis concludes that existing water supply bureaucracies need to be revitalized to effectively address key challenges in water security.Keywords: water security; supply water security; irrigation bureaucracy; polycentric water management; transboundary; Central Asia 2ff7e9595c
