Groundwater Replenishment System Virtual Tour

The Orange County Water District is the world’s largest advanced water purification system for potable reuse. You'll see the plant up close and learn about the three treatment steps it takes to purify treated wastewater to drinking water standards. The Groundwater Replenishment System takes treated wastewater and purifies it using a three-step process of microfiltration, reverse osmosis, and ultraviolet light with hydrogen peroxide. The GWRS produces 100 million gallons of water per day; enough water for 850,000 people.

Building a low-cost, real-time, aquifer monitoring network

The Nova Scotia Real-Time Aquifer Monitoring Network is a community-based, real-time groundwater monitoring network for tracking water levels in shallow aquifers. It was built after a 2016 drought in Nova Scotia caused over 1,000 domestic water wells to go dry. The water level meters used in the network are low-cost ($200), custom built units that use an ultrasonic sensor and IoT technology to measure the depth to the water table.

Regulating What We Can’t See: International Law and Transboundary Aquifers

Presentation by Gabriel Eckstein (environmental attorney and president of the International Water Resources Association) to the 46th IAH Congress, September 2019. He presents the fundamentals and governance challenges associated with sharing groundwater resources across state boundaries, including between nations, and conceptual models of various transboundary aquifers are included in the presentation.

Low Flow Groundwater Sampling Field Demonstration

This video is a field demonstration of groundwater sampling using the low flow method. It shows all the details of pump placement, drawdown control and measurements, flow cell programing, achieving the optimum pumping flow rate for steady-state pumping and drawdown, stabilization of field indicator parameters and sample collection.

The Story of Caves

The Story of Cave Development. How do caves and their decorations come into existence? Caves are formed and decorated by water - the tunnels, chambers, shafts and finely sculptured walls have all been carved out by flowing water. Stalactites, stalagmites, curtains, frozen waterfalls, rimstone dams and, the most remarkable all of cave formations - helictites have all be created by nothing more than water laden with minerals. This video explains how.

How Groundwater Moves in Southeast Minnesota [Part 1]

This realistic animation very effectively illustrates the nature and original of flow in karst terrain, including the dissolution process, flow along fractures, and disappearing streams, for example.
