Ground Water
25% of total fresh water is ground water; 1% is surface water and rest is locked in polar ice and glaciers
47.9% of America’s population uses ground water as drinking water source
42.4% of country’s irrigation water is ground water

The Survey: What We Asked
Type of organization Is a ground water supply shortage
expected? Why? How good is your information? What additional information is
most important? What should the federal
government do to help meet information gaps?

![Page 18: “Ground Water Level and Quality Monitoring” National Ground Water Association Presentation for:](https://reader036.vdocuments.net/reader036/viewer/2022062518/56814901550346895db62e37/html5/thumbnails/18.jpg)
Most Important Data to Expand: Differences in Response
State geologists highlighted the need to expand statewide aquifer mapping
NGWA members highlighted the need for on-line aquifer data
![Page 19: “Ground Water Level and Quality Monitoring” National Ground Water Association Presentation for:](https://reader036.vdocuments.net/reader036/viewer/2022062518/56814901550346895db62e37/html5/thumbnails/19.jpg)
Top 5 Desired Federal Actions Increase funding for cooperative
ground water quantity data collection
Increase funding for cooperative ground water quality data collection
Increase funding for aquifer mapping
Increase ground water availability research
![Page 20: “Ground Water Level and Quality Monitoring” National Ground Water Association Presentation for:](https://reader036.vdocuments.net/reader036/viewer/2022062518/56814901550346895db62e37/html5/thumbnails/20.jpg)
Top 5 Desired Federal Actions (cont.)
State geologists’ #5: Fund public education and outreach on water conservation
NGWA members’ #5: Develop a national ground water clearinghouse
![Page 21: “Ground Water Level and Quality Monitoring” National Ground Water Association Presentation for:](https://reader036.vdocuments.net/reader036/viewer/2022062518/56814901550346895db62e37/html5/thumbnails/21.jpg)
Survey Conclusions Most states are experiencing at
least local shortages now.
Most states have at least a reasonable estimate of the potential yield of major aquifers.
Few states have met any goals in collecting any type of ground water data.
![Page 22: “Ground Water Level and Quality Monitoring” National Ground Water Association Presentation for:](https://reader036.vdocuments.net/reader036/viewer/2022062518/56814901550346895db62e37/html5/thumbnails/22.jpg)
Survey Conclusions (cont.)
Priorities for collecting more data parallel types of data already being collected, perhaps because goals are not met.
Cooperative federal and state programs for ground water data collection favored
![Page 23: “Ground Water Level and Quality Monitoring” National Ground Water Association Presentation for:](https://reader036.vdocuments.net/reader036/viewer/2022062518/56814901550346895db62e37/html5/thumbnails/23.jpg)

Questions Posed to NGWA• What information needs does long-
term ground water quality and quantity monitoring address?
• What are the long-term ground water monitoring needs?
• What should the federal role be as regards long-term quality and quantity ground water monitoring?
![Page 25: “Ground Water Level and Quality Monitoring” National Ground Water Association Presentation for:](https://reader036.vdocuments.net/reader036/viewer/2022062518/56814901550346895db62e37/html5/thumbnails/25.jpg)
Questions Posed to NGWA cont.
• How does the federal government integrate its role with private sector, local and state government monitoring efforts?
• What are the priority actions that the federal government should take relative to long-term quality and quantity ground water monitoring?
![Page 26: “Ground Water Level and Quality Monitoring” National Ground Water Association Presentation for:](https://reader036.vdocuments.net/reader036/viewer/2022062518/56814901550346895db62e37/html5/thumbnails/26.jpg)
Why Undertake Long Term Ground Water Monitoring?
Assess the resource’s ability to support population growth and development
Help design and assess effectiveness of mgmt and protection programs
Identify short and long-term changes to ground water
Identify artificial ground water recharge opportunities
![Page 27: “Ground Water Level and Quality Monitoring” National Ground Water Association Presentation for:](https://reader036.vdocuments.net/reader036/viewer/2022062518/56814901550346895db62e37/html5/thumbnails/27.jpg)
Why Undertake Long Term Ground Water Monitoring cont.
Assess ground water and surface water interactions
Provide data for modeling Provide a more accurate estimate
of actual ground water withdrawals
![Page 28: “Ground Water Level and Quality Monitoring” National Ground Water Association Presentation for:](https://reader036.vdocuments.net/reader036/viewer/2022062518/56814901550346895db62e37/html5/thumbnails/28.jpg)

What Is the Federal Role? Support a collaborative
framework
(Ground Water Monitoring Subcommittee under ACWI raised as possible framework)
Develop guidelines for data
collection, quality control, storage and retrieval
![Page 30: “Ground Water Level and Quality Monitoring” National Ground Water Association Presentation for:](https://reader036.vdocuments.net/reader036/viewer/2022062518/56814901550346895db62e37/html5/thumbnails/30.jpg)

How to Optimize and Leverage Resources?
Federal government is “glue” to hold collective efforts together
States should develop state ground water availability and quality picture
Private sector firms should perform exploratory drilling and install monitoring wells
![Page 32: “Ground Water Level and Quality Monitoring” National Ground Water Association Presentation for:](https://reader036.vdocuments.net/reader036/viewer/2022062518/56814901550346895db62e37/html5/thumbnails/32.jpg)

What Should Federal Priorities Be? cont.
Others Demonstrating a commitment to
collaborative ground water quality and quantity data collection
Ensuring the availability of quality data at appropriate scale
Supporting research and development
Promoting public education and outreach
