This is a version of the Groundwater Lab (https://serc.carleton.edu/NAGTWorkshops/intro/activities/23416.html) previously shared as part of the Teaching Introductory Geology collection. It uses an online (https://pvw.kitware.com/sandtank/) version of an "ant farm" groundwater model to demonstrate groundwater flow and the behavior of wells. The lab is organized so that students have to predict the behavior of the model before observing it.

Students learn about porosity and permeability and relate these concepts to groundwater flow. They use simple materials to conduct a porosity experiment and use the data to understand how environmental engineers decide on the placement and treatment of a drinking water well.

This module discusses the hydrologic cycle and its impacts on the planet Earth. Additionally, the module addresses connections between the hydrologic cycle, climate and the impacts humans have had on the cycle.

In this lab, students investigate groundwater flow and water quality within a groundwater well field on the CSU campus. The well field is part of the GroundWater Education and Teaching (GetWET) Observatory south of the Hilton Inn off Centre Drive. Students determine water flow paths and rates as well as measure water quality parameters such as water temperature, pH, electrical conductivity, and dissolved oxygen.

Materials needed for this lab include:

Groundwater equipment: Groundwater well or wells adjacent to a perennial stream.
Water quantity equipment: Electronic water meter, staff, plate, tape, stop watch, and float to measure surface velocity.
Water quality equipment: pH, temperature specific conductance, and dissolved oxygen meters, bailer, and bucket to collect samples.
Other equipment: Map of site showing location of wells and stream.

Students are presented with examples of the types of problems that environmental engineers solve, specifically focusing on water quality issues. Topics include the importance of clean water, the scarcity of fresh water, tap water contamination sources, and ways environmental engineers treat contaminated water.

This activity is an outdoor lab in which students investigate the process of evaporation, record their findings, and use the data to make connections to the environment around them.

Our students will be studying and exploring the human impact on groundwater. They will study the water deprivation impacts both locally and in the San Joaquin Valley. Students will explore and come to understand the benefits of collecting rainwater. We partnered with the City of Eugene and had the wonderful Jackie come in. Our students brought in many of the materials including cardboard boxes, empty plastic containers (sour cream, water bottles,etc), tin foil, wax paper, duct tape,etc. We as teachers provided the underground sprinkler tubing cutting material, more tape and supplies. We tested this project with our 5th graders so we could make improvements and continue this project next year. In order to complete this project, we needed a full three weeks of working for an hour plus every day. We incorporated this project into our reading and science timeline.

This kit explores how sustainability within the Finger Lakes region of New York has been presented in the media with a particular focus on issues related to food, water and agriculture. Each of the seven lessons integrates media literacy and critical thinking with key knowledge and concepts related to sustainability. This kit is a companion to the nineteen-lesson collection, Media Constructions of Sustainability: Food, Water and Agriculture.

As Public Works Director of Nogales, Arizona, Alejandro Barcenas works to ensure a safe and secure water supply for the city’s 20,500 residents. His task isn’t easy: the city is located in an arid region just north of the United States–Mexico border, and its entire supply comes from groundwater.

Half of Nogales’ water comes from alluvial aquifers that are highly responsive to rainfall events. Though this convenient source of water recharges easily, it is also vulnerable to climate-related changes such as reduced precipitation and increased evaporation. The other half of the city’s groundwater comes from a lower-quality source—this water is more expensive to produce. To optimize the use of the two sources of groundwater into the future, Barcenas is contributing to the development of a modeling tool that simulates how the aquifers may change in response to climate.

Environmental and earth science students seldom have an opportunity to apply what they learn in class to the solution of real-world problems. With NSF support we have developed the prototype Plume Busters software, in which students take on the role of an environmental consultant. Following a pipeline spill, the environmental consultant is hired by the pipeline owner to locate the resulting plume created by the spill and remediate the contaminated aquifer at minimum monetary and time cost. The contamination must be removed from the aquifer before it reaches the river and eventually a downstream public water supply. The software consists of an interactive Java application and accompanying HTML linked pages. The application simulates movement of a plume from a pipeline break through a shallow alluvial aquifer towards the river. The accompanying web pages establish the simulated contamination scenario and provide students with background material on ground-water flow and transport principles. To make the role-play more realistic, the student must consider cost and time when making decisions about siting observation wells and wells for the pump-and-treat remediation system.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"One-third of the Earth’s fresh water comes from groundwater repositories. These terrestrial subsurface aquifers are an important source of our drinking water. Understanding the geochemistry and ecology of groundwater – including its microbial communities – is critical for keeping our water safe. A recent study sought to further understand a newly discovered superphylum – Patescibacteria. Patescibacteria is a very large superphylum, with more than 20 candidate phyla defined since 2015. This newly discovered class of bacteria is prevalent in groundwater environments and has limited genetic material. With such little genetic information to work from, the researchers wondered how these bacteria were able to adapt to changes and thrive in their aquatic environment. Using genome-resolved metagenomics, they evaluated sequence data from groundwater-residing Patescibacteria..."

The rest of the transcript, along with a link to the research itself, is available on the resource itself.

Students learn about contamination and pollution, specifically in reference to soil in and around rivers. To start, groups use light sensors to take light reflection measurements of different colors of sand (dyed with various amounts of a liquid food dye), generating a set of "soil" calibration data. Then, they use a stream table with a simulated a river that has a scattering of "contaminated wells" represented by locations of unknown amounts of dye. They make visual observations and use light sensors again to take reflection measurements and refer to their earlier calibration data to determine the level of "contamination" (color dye) in each well. Acting as engineers, they determine if their measured data is comparable to visual observations. The small-scale simulated flowing river shows how contamination can spread.

In this lesson, students will explore the causes of water pollution and its effects on the environment through the use of models and scientific investigation. In the accompanying activities, they will investigate filtration and aeration processes as they are used for removing pollutants from water. Lastly, they will learn about the role of engineers in water treatment systems.

In this presentation, we will discuss how saltwater intrusion affects small islands freshwater supplies, and how tourism is a significant part of this. In Zanzibar fresh water for drinking and other purposes come from rain that replenishes the island’s groundwater reservoir and in many cases freshwater is a scarce resource. On top of this, the excessive pumping in groundwater for the tourist industry increases the risk of salt water seeping into the freshwater magazine from the sea, thereby destroying the freshwater resource.

Students use spreadsheets to analyze the reasons why New Orleans has subsided in the past 250 years.

Learners will read or listen to a story about two sisters, Marisol and Sofia, as they explore the Sun's role in the water cycle. Additionally, numerous extension resources are included in the accompanying educator guide, such as suggestions for no-cost language arts activities, links to further science activities, a book walk cue chart to guide classroom discussion before, during, and after the story, a graphic organizer, and alignments to the National Science Education Standards (NSES) and the Next Generation Science Standards (NGSS).

Groundwater is one of the largest sources of drinking water, so environmental engineers need to understand groundwater flow in order to tap into this important resource. Environmental engineers also study groundwater to predict where pollution from the surface may end up. In this lesson, students will learn how water flows through the ground, what an aquifer is and what soil properties are used to predict groundwater flow.

This unit introduces the hydrological cycle to provide context for the module as a whole. It particularly focuses on those portions of the hydrological cycle that take place on land and that form the basis for water that is used by society. Students conduct a stakeholder analysis to better understand societal issues around water. Then the scientific exercise of the unit emphasizes quantitative approaches to describing the critical portions that humans have access to: surface water and shallow ground water. Students calculate residence times and fluxes between reservoirs and track water particles on an annual basis. They also explore available data sets for specific reservoirs such as snowpack and rivers.

This unit provides students with experience analyzing traditional (depth to water table measured in a well) and geodetic: GRACE (Gravity Recovery and Climate Experiment) data for monitoring changes in groundwater storage in the High Plains Aquifer. Variations across timescales are compared, from seasonal to interannual to decadal. This comparison highlights some of the challenges associated with quantifying changes in groundwater storage at the regional scale. Aquifer properties are used to consider changes in terms of both "depth to water table" and water storage. Students are asked to formulate explanations for the observed variations in the context of the water balance equation. Students compare their results to a multidecadal trend reported in the literature (Konikow, 2011).

In Unit 2, students learn how the techniques for water budgeting (covered in Unit 1) can be used to monitor both groundwater (High Plains Aquifer) and surface water (western mountain watershed) systems. Students interpret time-series plots that show the impact of drought years and wet years on underground water storage in the High Plains Aquifer and on snowpack and surface runoff in the western mountain watershed. They also consider the societal implications of water deficits through a series of pre-class readings, questions embedded in the assignments, and small and whole-group discussions. This unit can involve substantial computer time during which students use Excel to view and interpret hydrologic data. An alternative version with hard-copy graphs is also provided.

Online-adaptable: Both parts of this unit are completely digital and thus at a logistical level it can be switched to online fairly easily. However, due to the relative complexity of the data investigations, there will still be quite a bit of instructor support needed and/or extended small group that should be arranged.
