The Santa Cruz River has long been the backbone of the region’s natural and cultural heritage. Although the river has changed since humans first arrived in the region 12,000 years ago, the river still exists and is a “living” entity that continues to support wildlife and communities along its course. Throughout Arizona, the release of effluent maintains flows of many river reaches. The Santa Cruz River is fortunate to have three stretches with effluent flows—one near Nogales in Santa Cruz County and two near Tucson in Pima County.

The sustainability of groundwater is threatened by overexploitation and by pollution, exacerbated by perturbations of hydrological cycle stemming from climate change exerting poorly understood water quantity and quality risks with uncertain outcomes. A recent UNESCO publication on managed aquifer recharge (MAR) has provided unequivocal evidence that MAR is a sustainable nature-based engineering approach for enhancing climate resilience and other social, economic, and environmental benefits of groundwater.

WRRC Brown Bag Webinar: Arizona Project WET's Groundwater Videos in the Making
Arizona Project WET has been teaching about the groundwater system for over two decades using everything from two-dimensional drawings to tubs of earth materials and the ever-popular sand tank groundwater model. Helping students to understand this critical unseen system is no easy task. With the support of the Arizona Department of Water Resources, APW partnered with Esser Design to develop a series of nine videos about the groundwater system. In the process, we encountered a variety of challenges and interesting questions on the best way to communicate on the groundwater system.
