Groundwater is water located beneath the earth's surface in soilpore spaces and in the fractures of rock formations. A unit of rock or an unconsolidated deposit is called an aquifer when it can yield a usable quantity of water. The depth at which soil pore spaces or fractures and voids in rock become completely saturated with water is called the water table. Groundwater is recharged from, and eventually flows to, the surface naturally; natural discharge often occurs at springs and seeps, and can form oases or wetlands. Groundwater is also often withdrawn for agricultural, municipal and industrial use by constructing and operating extraction wells. The study of the distribution and movement of groundwater is hydrogeology, also called groundwater hydrology.
Typically, groundwater is thought of as liquid water flowing through shallow aquifers, but technically it can also include soil moisture, permafrost (frozen soil), immobile water in very low permeability bedrock, and deep geothermal or oil formation water. Groundwater is hypothesized to provide lubrication that can possibly influence the movement of faults. It is likely that much of the Earth's subsurface contains some water, which may be mixed with other fluids in some instances. Groundwater may not be confined only to the Earth. The formation of some of the landforms observed on Mars may have been influenced by groundwater. There is also evidence that liquid water may also exist in the subsurface of Jupiter's moon Europa.

Groundwater is an important source of fresh water for industries, municipalities, farms, and rural homeowners in British Columbia. BC operates a network of over 180 observation wells to track groundwater levels in areas of high use. This information helps us to see how healthy aquifers are so we can make good decisions about groundwater use in BC.

Considerations For Use of Passive/No-Purge Groundwater Sampling
Considerations For Use of Passive/No-Purge Groundwater Sampling
Considerations For Use of Passive/No-Purge Groundwater Sampling
Passive groundwater sampling is a cost-saving approach accepted by regulators. Data quality often meets or exceeds that of purge sampling. Low-flow sampling methods replaced bailer sampling due to data quality concerns of the “rough and tumble” bailer approach, but also to minimize waste footprint. No-purge sampling often reduces waste to zero and takes a fraction of the time that it takes to wait for purge parameter stability. Now, Department of Defense-supported studies are showing equivalent data quality too. A recent ASTM Standard D7929-14 provides a nationally-recognized standard for implementation.

Presenter Sanford (Sandy) Britt is a SERDP and ESTCP researcher with more than 10 years of experience studying passive well flow dynamics and passive sampling. Mr. Britt is also the developer of one of the passive sampling methods in the ASTM Standard. His research background gives him a unique perspective on how wells work and how those dynamics impact groundwater sampling results—whether sampling passively or by pumping. Mr. Britt will present background on the function of wells and why passive sampling often closely resembles pumped sampling results. He will also present research on passive sampling data comparisons and findings on data variability among methods. The presentation will provide attendees with an important basic understanding about the differences among sampling approaches, what specific devices are capable of, and their limitations.

Historical failure to recognise the connection between surface water and groundwater and to manage river and groundwater systems conjunctively has led to over allocation of water resources. Examples of river systems that have been depleted by groundwater pumping, for example, are well documented.
Although conjunctive management of surface water and groundwater is preferred, it requires information on the magnitude of the interaction between the two reservoirs. While numerous different methods have been used to measure the exchange flux, the usefulness of many of these methods is limited by the very high spatial and temporal variability of the fluxes involved.
Methods that have been used successfully to estimate spatial variations in groundwater discharge to streams, over scales of interest to water managers, include water and solute mass balances. Groundwater discharge to streams can be determined from differences between river flow gaugings made at different points along the river, and from measurements of conservative ion concentrations. Sensitivity is greatest, however, when tracers are used whose concentration in the groundwater greatly exceeds that in surface water. This condition is often best met for the naturally occurring radioactive element radon (222Rn). Since radon in surface water is lost by exchange with the atmosphere (which is low in radon), a large contrast in concentration with the groundwater is maintained.
Measuring changes in groundwater discharge with time is more difficult, because the required frequency of measurements means that only parameters that can be measured remotely are suitable.
Historical failure to recognise the connection between surface water and groundwater and to manage river and groundwater systems conjunctively has led to over allocation of water resources. Examples of river systems that have been depleted by groundwater pumping, for example, are well documented.
Although conjunctive management of surface water and groundwater is preferred, it requires information on the magnitude of the interaction between the two reservoirs. While numerous different methods have been used to measure the exchange flux, the usefulness of many of these methods is limited by the very high spatial and temporal variability of the fluxes involved.
Methods that have been used successfully to estimate spatial variations in groundwater discharge to streams, over scales of interest to water managers, include water and solute mass balances. Groundwater discharge to streams can be determined from differences between river flow gaugings made at different points along the river, and from measurements of conservative ion concentrations. Sensitivity is greatest, however, when tracers are used whose concentration in the groundwater greatly exceeds that in surface water. This condition is often best met for the naturally occurring radioactive element radon (222Rn). Since radon in surface water is lost by exchange with the atmosphere (which is low in radon), a large contrast in concentration with the groundwater is maintained.
Measuring changes in groundwater discharge with time is more difficult, because the required frequency of measurements means that only parameters that can be measured remotely are suitable.

Dr. Thomas Harter, Future of Groundwater Management in California
This lecture introduces the status of water conditions in California, including with the extent of the ongoing drought and its effects on groundwater resources, and consequences. It concludes with an introduction to California’s new regulations for groundwater sustainability and quality protection and some insight into next steps.
Groundwater is a critical resource for California water management, storing water from the rainy season for dry and hot summers, and from wet years for droughts. The future of groundwater use, protection, and management in California’s agricultural landscape will be an increasingly integrated approach to co-manage water quality and quantity of surface water and groundwater.

How Secant Piles Control Groundwater - Murray Combined Sewer Overflow Control project
Learn how King County Wastewater Treatment Division creates safe underground work environments using a construction technique called secant piles. At the Murray Combined Sewer Overflow Control project in West Seattle, King County used interlocking concrete cylinders called secant piles to create a watertight ring. The ring kept groundwater out while the inside of the ring was excavated, which protected nearby homes, streets and utilities from settlement. King County’s Murray CSO Control project is building a 1 million tank to keep sewage and stormwater out of polluted Puget Sound.

87 out of 117 groundwater well tests came back with too much contamination.
"I've had suspicions about it anyways, and I know a lot of research has been done over the years, and I know a lot of it has been inconclusive," said Paige Beratta, who lives near Lake Julian.
The coal ash pond sits about 100 feet from her home. She's on city water, and still won't drink it.
"We just, I don't, I've had concerns about it, we have one of those 5 gallon jugs that dispenses," said Beratta.
Near Salisbury, the state sent letters to 19 homes and a church advising not to drink, or cook with their well water.
In a statement Duke Energy said there is no proof coal ash is the reason for the contamination. According to Duke, contaminated water from coal ash would have boron and sulfates. These tests mostly came back with too much iron and manganese.
"They're both naturally occurring, so, you know, in that way, I'd say it's not very surprising. Although, I'd say they still do exceed state groundwater standards," said Sarah Young, from DENR.
Young says they won't know if Duke caused the contamination until the fall.
Everybody who had their well tested will receive the results from DENR and a health evaluation from DHHS.

It's called groundwater!
Groundwater is an important source of fresh water for industries, municipalities, farms, and rural homeowners in British Columbia. BC operates a network of over 180 observation wells to track groundwater levels in areas of high use. This information helps us to see how healthy aquifers are so we can make good decisions about groundwater use in BC.

Considerations For Use of Passive/No-Purge Groundwater Sampling
Considerations For Use of Passive/No-Purge Groundwater Sampling
Passive groundwater sampling is a cost-saving approach accepted by regulators. Data quality often meets or exceeds that of purge sampling. Low-flow sampling methods replaced bailer sampling due to data quality concerns of the “rough and tumble” bailer approach, but also to minimize waste footprint. No-purge sampling often reduces waste to zero and takes a fraction of the time that it takes to wait for purge parameter stability. Now, Department of Defense-supported studies are showing equivalent data quality too. A recent ASTM Standard D7929-14 provides a nationally-recognized standard for implementation.
Presenter Sanford (Sandy) Britt is a SERDP and ESTCP researcher with more than 10 years of experience studying passive well flow dynamics and passive sampling. Mr. Britt is also the developer of one of the passive sampling methods in the ASTM Standard. His research background gives him a unique perspective on how wells work and how those dynamics impact groundwater sampling results—whether sampling passively or by pumping. Mr. Britt will present background on the function of wells and why passive sampling often closely resembles pumped sampling results. He will also present research on passive sampling data comparisons and findings on data variability among methods. The presentation will provide attendees with an important basic understanding about the differences among sampling approaches, what specific devices are capable of, and their limitations.

Managing Groundwater for Drought, Clean Water, Food Security, and Ecosystems
Managing Groundwater for Drought, Clean Water, Food Security, and Ecosystems
Groundwater is a critical source of drinking water for many Americans, it is the drought insurance for 40% of our planet's agriculture, and it sustains many aquatic ecosystems. Understanding this hidden resource is a key to its sustainable management. This lecture was co-sponsored by The Boeing Company.
Thomas Harter, PhD, is the Robert M. Hagan Endowed Chair in Water Management and Policy at the University of California, Davis.

How Secant Piles Control Groundwater - Murray Combined Sewer Overflow Control project
How Secant Piles Control Groundwater - Murray Combined Sewer Overflow Control project
Learn how King County Wastewater Treatment Division creates safe underground work environments using a construction technique called secant piles. At the Murray Combined Sewer Overflow Control project in West Seattle, King County used interlocking concrete cylinders called secant piles to create a watertight ring. The ring kept groundwater out while the inside of the ring was excavated, which protected nearby homes, streets and utilities from settlement. King County’s Murray CSO Control project is building a 1 million tank to keep sewage and stormwater out of polluted Puget Sound.

Rosemary Knight, “Seeing Into Earth: Imaging Our Groundwater Aquifers”
Watch, learn and connect: https://stanfordconnects.stanford.edu/
How can we best manage water in California? Professor Rosemary Knight advocates using geophysical imaging to transform our management of groundwater.
Rosemary Knight, PhD ’85, is the George L. Harrington Professor in the School of Earth Sciences and senior fellow, by courtesy, at the Woods Institute for the Environment. Her research focuses on the development of geophysical methods to understand what’s occurring in the top 100 meters of Earth. By acquiring images of the near-surface region, researchers can monitor systems and extract information to help inform decisions regarding the evaluation and management of groundwater resources.
This Stanford+Connects micro lecture was filmed on location in Sacramento, California. Stanford+Connects is a program of the Stanford Alumni Association.

Groundwater Tests Near Coal Ash Sites Show Con
ASHEVILLE, N.C. -- Initial testing from the Department of Natural Resources finds contaminated groundwater near Duke Energy's coal ash ponds.
The Lake Julian and Cliffside power stations were amongst those with positive results.
The levels of contamination exceeded state standards, but in almost every case the groundwater would be acceptable under federal standards, according to DENR.
87 out of 117 groundwater well tests came back with too much contamination.
"I've had suspicions about it anyways, and I know a lot of research has been done over the years, and I know a lot of it has been inconclusive," said Paige Beratta, who lives near Lake Julian.
The coal ash pond sits about 100 feet from her home. She's on city water, and still won't drink it.
"We just, I don't, I've had concerns about it, we have one of those 5 gallon jugs that dispenses," said Beratta.
Near Salisbury, the state sent letters to 19 homes and a church advising not to drink, or cook with their well water.
In a statement Duke Energy said there is no proof coal ash is the reason for the contamination. According to Duke, contaminated water from coal ash would have boron and sulfates. These tests mostly came back with too much iron and manganese.
"They're both naturally occurring, so, you know, in that way, I'd say it's not very surprising. Although, I'd say they still do exceed state groundwater standards," said Sarah Young, from DENR.
Young says they won't know if Duke caused the contamination until the fall.
Everybody who had their well tested will receive the results from DENR and a health evaluation from DHHS.
