– Vulnerability Assessments (VA)
– Emergency Response Plans (ERPs)
– Research
– Funding
5
Investments Generate Jobs
• $1 billion in water infrastructure construction creates 40,000 jobs (American Public Works Association)
• $ 1 billion in water efficiency projects creates 22,000 construction, plumbing and manufacturing jobs (Alliance for Water Efficiency)
• Recent infrastructure investments of $45.2 billion raised GDP by 2.7% and created 2.7-3.7 million jobs (WH Council of Economic Advisors)
7
Investments Spur Environmental Technology Exports
• Water is large and growing business:
– $800B global environment technologies market
– $309B is U.S. industry share
– 1.7 million jobs; 61,000 small businesses
– $111B is water technologies and services
• Estimated U.S. trade surplus of $13B on environmental technologies.
• U.S. leading edge approach to environmental management issues does enhance exports.
• EPA partnership with Commerce & trade promotion agencies is growing.

3. Some Issues and Technology Needs
• Nutrient pollution
• Hydraulic fracturing
• Next generation water and wastewater treatment technologies
• Wet weather pollution management and water re-use
• Climate 'Nonstationarity' in Infrastructure Design
• Emerging contaminants & pathogens of concern
9
Nutrient Pollution
• Issue: Further reduction in nitrogen and phosphorus concentrations are needed to achieve ecological goals. Nonpoint sources of pollution are major contributors but have unique measurement, monitoring, and management challenges
• Example Needs:
– Improved models and tools for assessing point and nonpoint sources and management strategies. These need to be technically sound, flexible, and suitable for decision makers. Approaches will vary based on major systems (e.g. Great Lakes, New England, etc..)
– Remote sensing techniques for real time monitoring and reporting water quality of fresh, estuarine and coastal waters.
– Inexpensive sensors, data acquisition and other tools for measuring the performance of differing nonpoint source management practices.
– Nutrient removal treatment technologies
10
Hydraulic Fracturing
• Issue: The U.S. has vast reserves of natural gas that are commercially viable as a result of advances in horizontal drilling and hydraulic fracturing technologies. EPA is working with states and other key stakeholders to help ensure that natural gas extraction does not come at the expense of public health and the environment. There is a critical role for technology in supporting responsible development of these shale gas resources.
• Example Needs:
– Industry and stakeholder input/response to ongoing EPA study of the potential impacts of hydraulic fracturing on drinking water resources .
– Input to May 2012 Draft Permitting Guidance for Oil and Gas Hydraulic Fracturing Activities Using Diesel Fuels and follow-on EPA rules and guidance.
– Technologies for treating and/or reuse of fracking fluids and stormwater from well sites.
– Sensors and data management systems for ensuring the integrity of the resource development and utilization process.
11
Next Generation Water and Wastewater Treatment Technologies
• Issue: Demand is increasing for new approaches to treat and reuse water and wastewater. This is being driven by increases in energy prices, shortages of water supply, projected climate impacts, emerging contaminant concerns, and other factors.
• Example Needs: – Decision support tools to compare conventional and novel/alternative water
service approaches. – Treatment technologies for groupings of volatile organic chemicals at low
concentrations (e.g. aeration and granular activated carbon). – Technologies for treating ammonia, fluoride and other contaminants of
relevance to small systems. – Advanced technologies for energy recovery at drinking water and wastewater
treatment facilities. – Improved water conveyance technologies and innovative approaches for
rehabilitation and replacement of aging water infrastructure. – Private sector commercialization of ORD developed water technologies.
12
Wet Weather Management • Issue: By weaving natural processes into the built environment, green
infrastructure (GI) provides not only stormwater management, but also flood mitigation, air quality management, and other benefits to advance sustainable communities. Technology development and assessment is needed to realize the full potential of GI systems.
• Example Needs: – Develop and evaluate integrated green and grey approaches at the sewer-
shed or urban watershed scales. – Measure effectiveness to improve current urban hydrologic cycles and
management approaches to reduce risks. – Address any gaps regarding GI performance and costs (e.g., long-term
O&M costs vs. grey infrastructure) – Determine GI BMP benefits for aquatic ecosystems and ecological
functions at the watershed level. – Develop predictive models for designing green/grey urban systems.
13
Climate ‘Nonstationarity’
• Issue: There is increasing evidence that precipitation will occur in less frequent, but more intense, rainfall events, meaning wetter wet periods and dryer dry periods. Further, coastal areas are facing sea level rise and related storm surge. This poses a challenge to both existing and new infrastructure design.
• Example Needs:
– Updated precipitation ‘design storms,’ flood frequency information, and floodplain mapping.
– Infrastructure vulnerability assessments to identify risk, and adaptive management to proactively address threats.
– Integrated Water Resource Management across sectors within watersheds, to manage competition for water resources (drinking water supply, energy production, agriculture, industry, and ecological needs)
14
Emerging Contaminants and Pathogens
• Issue: New and emerging contaminants and pathogens are of growing concern. They are unregulated, may be present but at very low levels, and their health impact may be in question. Among emerging contaminants are pharmaceuticals and personal care products, industrial chemicals present at low concentrations, and chemicals that may affect hormone status, referred to as "endocrine disruptors."
• Example Needs: – Stressor/dose response models to help assess the need for and nature of
any regulatory action.
– Analytical methods for determining presence and concentrations of contaminants and microorganisms of concern in source to finished water.
– Assessments of cumulative risk of mixtures in drinking water.
– Technologies and technology assessments of varying treatment approaches (e.g. membranes, ozone and chlorine).
15
Partnerships: EPA and DoD Net Zero
• EPA-ORD and Army signed a Memorandum of Understanding (MOU) in Nov 2011 to: – Demonstrate cutting-edge technology solutions to advance
both institutions' goals for increased resource efficiency and balanced resource use.
– Work jointly to advance the development and demonstration of new applications and technologies that can be used on installations striving towards NetZero water, waste and energy goals
– First pilots at Fort Riley, KS and Joint Base Lewis McChord, WA
• Broadened to DoD in February 2012

Focus Areas Indentified Thus Far
•Drinking Water/Waste Water Systems – water reuse,
treatment/distribution, energy recovery and efficiency
•Aging Infrastructure – monitoring and leak detection, optimization
combinations of old and new distribution lines
•Stormwater Management – wet weather flows, green
infrastructure, and water reuse
17
Water Technology Innovation Cluster • Businesses, universities and governments working together to
promote economic growth and technology innovation. • Focus in greater Cincinnati, Dayton, Northern Kentucky and Indiana. • Initial emphasis placed on drinking water. • Scope includes wastewater, storm water, and water reuse
technologies. With increasing water scarcity they increasingly impact each other.

Recognizing Synergies: Wastewater Treatment and Energy
Essex Junction WWTP (VT) -- combined heat and power system that uses almost 100% of the plant’s self-generated methane as a renewable fuel. Producing over 400,000 kilowatt hours of energy each year, while saving $37,000 in electricity costs and preventing 600,000 lbs of CO2 emissions from power plants annually.
Gloversville-Johnstown WWTP (NY) investing in biogas energy to provide the facility with 100% of its electrical power, while saving $400,000 on electricity costs annually.
Milwaukee Municipal Sewerage District (WI) building a pipeline to use methane gas from a local landfill to fuel one of their wastewater treatment plants; hoping to save $25 to $65 million dollars on electricity costs over the next 20 years.
Milwaukee also uses solar panels at its Jones Island Water Reclamation Facility to offset energy costs, and has various green infrastructure programs, including participating in the Regional Green Roof Initiative and assisting property owners with rain garden development.
