For the past three years our agencies have coordinated like never before to help ensure that all Americans have access to safe, reliable water supplies essential for our communities, our economy, and for recreation and the environment. On October 13, 2020, Executive Order 13956, titled “Modernizing America’s Water Resource Management and Water Infrastructure” was issued formally establishes an interagency Water Subcabinet that will streamline the Federal government’s approach to managing America’s water resources and work to upgrade our Nation’s water infrastructure, safeguard public health, and create jobs. The Water Subcabinet includes the U.S. Department of the Interior (DOI), U.S. Environmental Protection Agency (EPA), the U.S. Department of Agriculture (USDA), the Department of the Army (Civil Works), the U.S. Department of Commerce (DOC) represented by the National Oceanic and Atmospheric Administration (NOAA), and the U.S. Department of Energy (DOE). Pursuant to Executive Order 13956, the Water Subcabinet is delivering the following items: • Section 4 “Reducing Inefficiencies and Duplication” – The first assessment of Federal water related task forces, working groups, and other formal cross-agency initiatives (Federal interagency working groups) being considered for coordination, consolidation, or retirement. This assessment, along with recommendations for coordination, consolidation, and retirement, will be updated and provided to CEQ, OSTP, and OMB quarterly, beginning January 2021, per the methodology described in the Section 4 Federal Action Plan. • Section 5 “Improving Water Resource Management” – The initial report and recommendations, which examine specific National water resources and infrastructure issues. • Section 7 “Integrated Infrastructure Planning” – The report and recommendations to support integrated planning and coordination among agencies to modernize our Nation’s water infrastructure. • Section 8 “Water Sector Workforce” – The Report on Recommendations to Ensure Maintenance and Sustainability of America’s Water Workforce. 3 Sec. 4. Reducing Inefficiencies and Duplication. Currently, hundreds of Federal water related task forces, working groups, and other formal cross-agency initiatives (Federal interagency working groups) exist to address water resource management. Within 90 days of the date of this order, the Water Subcabinet shall, to the extent practicable, identify all such Federal interagency working groups and provide recommendations to the Chairman of the Council on Environmental Quality (CEQ), the Director of the Office of Management and Budget (OMB), and the Director of the Office of Science and Technology Policy (OSTP) on coordinating and consolidating these Federal interagency working groups, as appropriate and consistent with applicable law. Pursuant to section 4 of Executive Order 13956, the Water Subcabinet submits the following report and recommendations (“Section 4 Action Plan”). Reducing Inefficiencies and Duplication Introduction Within the Federal government and across the Nation, numerous Federal departments, agencies, and bureaus facilitate Federal water related task forces, working groups, and other formal cross-agency initiatives (Federal interagency working groups) that are tasked with similar, if not identical, missions, goals, and objectives across geographic and subject matter areas. Duplication and redundancy creates inefficiencies and delays policy implementation, resulting in wasteful spending, dilution of dedicated resources, and confusion between participants and decision makers, as well as beneficiaries and external stakeholders. More fundamentally, such duplicative efforts risk of undermining the mission of the working groups themselves. Through increased coordination and streamlining the Federal interagency working groups, Federal, state, and local participants will achieve: • Increased productivity and effectiveness in accomplishing the intended mission of the Federal interagency working groups; • More efficient and focused use of resources for better delivery of services and implementation of activities at the regional, state, and local levels; • Improved communication and time management; • Greater transparency and accountability to better capture progress and success, expedite processes, and increase responsiveness in decision making; and • A clear and up to date vision of the current status, challenges, and accomplishments of these working groups. Methodology To reduce unnecessary duplication across the Federal government, the Water Subcabinet will undertake quarterly or other regularly scheduled assessments of existing Federal interagency working groups and provide consistent recommendations to coordinate, consolidate, or retire existing Federal interagency working groups. The Water Subcabinet will initiate the following practices: 4 • Quarterly Data Call of All Federal Interagency Working Groups o Member agencies of the Water Subcabinet will, beginning in January 2021, update quarterly the list of Federal interagency working groups and provide recommendations to the Chairman of CEQ, the Director of OMB, and the Director of OSTP on coordinating, consolidating, or retiring existing and new Federal interagency working groups. o To organize and assess associated and related Federal interagency working groups, recommendations will be categorized using either a Geographic (i.e., the Great Lakes region) or Subject Matter (i.e., forecasting) area. Moving forward, additional categories may be established as deemed appropriate. • Designation of One Federal Lead o The Department, Agency or Bureau that is designated as the lead entity in an identified Geography or Subject Matter area, will be tasked with ensuring quarterly updates are provided and making recommendations for coordinating, consolidating, or retiring related interagency working groups. o Upon adoption by the Executive Office of the President of the recommendations, the lead Department, Agency or Bureau working in close coordination with the Water Subcabinet, shall implement the recommendation to coordinate, consolidate, or retire the existing Federal interagency working groups. • Assessment & Recommendations o Working groups within an individual Geographic or Subject Matter area, the Water Subcabinet shall be assessed for coordination, consolidation or retirement based on based on, but not limited to, the following criteria: . Mission Accomplished – Has the Federal interagency working group met its specified mandate? . Frequency and Relevance – When did the Federal interagency working group last meet? How often does the Federal interagency working group meet? . Origin and Authority – How was the Federal interagency working group created (i.e., Legislation, Executive Actions including Executive Orders and Presidential Memorandum, Court Settlement, etc.)? Under what authority does the working group convene? What authority, if any, does the working group administer? Recommendation Recommendations to CEQ, OMB, and OSTP must include the following metrics for consideration: • Justification – Summary of the data call, categorization, and assessment process; • Propose New Organizational Alignment for the Federal Interagency Working Groups – As described and supported by the Justification summary; and • Appropriations Summary – The Water Subcabinet will provide a snapshot analysis of the current appropriations of each Federal interagency working group

This 8 makes a moist parcel lighter than a dry parcel of the same temperature and 9 pressure. This effect is referred to as the vapor buoyancy effect and has of- 10 ten been overlooked in climate studies.

To maintain the 14 uniform buoyancy distribution, temperature increases toward dry atmosphere 15 columns to compensate reduction of vapor buoyancy. The temperature differ- 16 ence between moist and dry columns would increase with climate warming 17 due to increasing atmospheric water vapor, leading to enhanced OLR and 18 thereby stabilizing Earth’s climate.

Although spring water or groundwater products are often sold as “pure,” http://anrcatalog.ucdavis.edu their water quality is different from that of pure water. In partnership with Naturally, ground water contains mineral ions. These ions slowly dissolve from soil particles, sediments, and rocks as the water travels along mineral surfaces in the pores or fractures of the unsaturated zone and the aquifer. They are referred to as dis- solved solids. Some dissolved solids may have originated in the precipitation water or river water that recharges the aquifer. A list of the dissolved solids in any water is long, but it can be divided into three groups: major constituents, minor constituents, and trace elements (Table 1). The http://www.nrcs.usda.gov total mass of dissolved constituents is referred to as the total dissolved solids (TDS) concentration. In water, all of the dissolved solids are either positively charged ions Farm Water (cations) or negatively charged ions (anions). The total negative charge of the anions always equals the total positive charge of the cations.

  • A Public Health Legal Guide to Safe Drinking Water
    A Public Health Legal Guide to Safe Drinking Water Prepared by Alisha Duggal, Shannon Frede, and Taylor Kasky, student attorneys in the Public Health Law Clinic at the University of Maryland Carey School of Law, under the supervision of Professors Kathleen Hoke and William Piermattei. Generous funding provided by the Partnership for Public Health Law, comprised of the American Public Health Association, Association of State and Territorial Health Officials, National Association of County & City Health Officials, and the National Association of Local Boards of Health August 2015 THE PROBLEM: DRINKING WATER CONTAMINATION Clean drinking water is essential to public health. Contaminated water is a grave health risk and, despite great progress over the past 40 years, continues to threaten U.S. communities’ health and quality of life. Our water resources still lack basic protections, making them vulnerable to pollution from fracking, farm runoff, industrial discharges and neglected water infrastructure. In the U.S., treatment and distribution of safe drinking water has all but eliminated diseases such as cholera, typhoid fever, dysentery and hepatitis A that continue to plague many parts of the world. However, despite these successes, an estimated 19.5 million Americans fall ill each year from drinking water contaminated with parasites, bacteria or viruses. In recent years, 40 percent of the nation’s community water systems violated the Safe Drinking Water Act at least once.1 Those violations ranged from failing to maintain proper paperwork to allowing carcinogens into tap water. Approximately 23 million people received drinking water from municipal systems that violated at least one health-based standard.2 In some cases, these violations can cause sickness quickly; in others, pollutants such as inorganic toxins and heavy metals can accumulate in the body for years or decades before contributing to serious health problems.

  • Case Study: Water and Ice
    Case Study: Water and Ice Timothy A. Isgro, Marcos Sotomayor, and Eduardo Cruz-Chu 1 The Universal Solvent Water is essential for sustaining life on Earth. Almost 75% of the Earth’s surface is covered by it. It composes roughly 70% of the human body by mass [1]. It is the medium associated with nearly all microscopic life pro- cesses. Much of the reason that water can sustain life is due to its unique properties. Among the most essential and extreme properties of water is its capabil- ity to absorb large amounts of heat. The heat capacity of water, which is the highest for compounds of its type in the liquid state, measures the amount of heat which needs to be added to water to change its temperature by a given amount. Water, thus, is able to effectively maintain its temperature even 1 when disturbed by great amounts of heat. This property serves to main- tain ocean temperatures, as well as the atmospheric temperature around the oceans. For example, when the sun rises in the morning and a large amount of heat strikes the surface of the Earth, the vast majority of it is absorbed by the ocean. The ocean water, however, does not exhibit a drastic increase in temperature that could make it inhospitable to life. In constrast, when the sun sets in the evening and that heat is taken away, the oceans do not become too cold to harbor life. Water also has high latent heats of vapor- ization and melting, which measure the amount of heat needed to change a certain amount of liquid water to vapor and ice to liquid, respectively.
