Webinar Outline
 Brief history of U.S. water policy
 Major federal water laws and agencies
 Ongoing and emerging challenges
 Recent policy trends and innovations
2
Overview of Water Policy
 Two traditional threads
 Water use/
consumption
 Water quality
 Policy fragmentation
 State vs. federal
 Increasing:
 coordination
 landscape-scale
management
 public involvement
 ecosystem restoration
 adaptive management

History
 Colonial-1850: local control and

abundance
1850-1900: expansion, transport
1900-1950: water supply
infrastructure
1950-1980: Environmental era
1980-2000: Devolution,
experimentation, and collaboration

Clean Water Act (CWA)
 Passed in 1972
 Two major mechanisms:
 Designate uses and WQ standards for
waterways
 Regulate point sources of pollution

National Pollution Discharge Elimination
System (NPDES)—national permitting system
7
Other Federal Laws
 Safe Drinking Water Act (SDWA)
 Public drinking water standards
 Drinking Water State Revolving
Fund
 Water Resources Development
Act (WRDA)
 New bill in conference now
8
Water Agencies
 U.S. Army Corps of Engineers
(USACE)
 Traditionally focused on navigation,
flood control
 Manages 25% of U.S. hydroelectric
power
 Bureau of Reclamation
 Provides water storage for
irrigation, drinking water,
recreation
9
Water Agencies
 Environmental Protection Agency (EPA)
 Primary federal agency in charge of water
quality
 Administers CWA provisions, including:



NPDES
List of impaired waters
Technical, financial resources for pollution
reduction
 CWSRF & DWSRF

Water Supply
12
Water Usage by Sector
Municipal supply:
residential &
commercial uses
4%
3% 1% 1%
Power Generation
Agriculture
11%
49%
Non-domestic Public
Supply
Industrial
31%
Livestock and
Aquaculture
Mining
2005 USGS data, last year federal estimates are available
13
Water Supply: Surface Water Rights
 Three traditional state
doctrines
 Riparian rights (eastern
states)

Water rights part of
property
 Prior appropriation
(western states)

“First in time, first in
right”
 Hybrid systems (Great
Plains & Pacific coast)
14
Water Supply: Groundwater
 Groundwater policies
disconnected from surface
water
 Some states combining
ground- and surface water
policies
 Typically first come, first
served policies
 Mostly privately developed
 Groundwater depletion
serious concern
15

16
Water Supply: Emerging Issues
 Prior appropriation: no efficiency
incentive
 Use it or lose it
 States adjusting policies
 Increased pressure on existing
water supplies
 Population growth
 Increased per capita use
 Aging infrastructure
 State, local (and private) systems,
with federal support
Clean Water Action (cleanwater.org)
17
Water Supply: Efficiency and
Conservation
 Mostly state/local effort thus far (EPA
technical support)
 Water loss management
 Water reuse and recycling programs
 Market mechanisms
 Cooperative water management
 Conjunctive land use and water
planning

Water Quality
20
Water Quality
 Environmental
movement of 1960s
changed perception of
water
 Initial concern with
point source pollution
 Heavy metals, sewage,
petrochemicals, PCBs
 CWA, NPDES
 40 years after CWA, still
significant impairment
Impaired Waters of the US:
100,000 miles of rivers and streams
2.5 million acres or lakes
800 mi2 of bays and estuaries
55% of streams in poor condition for
aquatic life
(source: EPA)
21
Water Quality
 Nonpoint source (NPS)
pollution
 Variety of sources,
difficult to identify
 Nutrients (N&P),
sediment, road
chemicals
 Now major source of
water impairment

Emerging Pollutants of Concern
 Household chemicals with uncertain impacts
 Pharmaceuticals
 Household cleaners
 Personal care products
 Widespread
24
Emerging Pollutants of Concern
Kolpin et al. 2002. Pharmaceuticals, hormones, and other organic wastewater contaminants in U.S. streams,
19909-2000: a national reconnaissance. Environ. Sci. Tech.
25
Water Quality
 1990s transition to holistic WQ
management
 1992 CWA amendments: Total
Maximum Daily Load (TMDL)
 Whole water body management
 Determines uses, calculates acceptable
pollutant levels
 Apportions levels to various actors
26
Water Quality
 TMDL process addresses PS
and NPS
 Mandatory limits for PS, only
voluntary for NPS
 Watershed-based, cut across
political boundaries
 Public involvement

Coordination and Collaboration
 Agencies increasingly
working together
 Federal-state-localprivate collaboration
 Integrate water supply
mgmt, WQ mgmt
 California Federal-BayDelta Program
(CALFED)
29
Watershed Management
•Management by basin,
rather than jurisdiction
•Goes hand-in-hand with
coordination and
collaboration
•Targets NPS
•TMDL process
•Citizen involvement key
•Civic watershed groups
related to implementation
of TMDL plans1

Public Involvement
 Public awareness of
water issues
 Multiple use
management
 EPA 319 Program
31
Ecosystem Restoration
 Hundreds of years of water system modification and
degradation
 Loss of ecosystem services:
 Flood control & storage
 Water filtering
 Wildlife & fisheries habitat
 Storm protection
Example: Comprehensive Everglades
Restoration Plan
32
Adaptive Management
 Experimentation in
policy design
 Importance of
monitoring,
flexible
administration
 Response to climate
change
