2020 WOTUS Rule
The United States has had a tumultuous relationship with one of its most precious resources — water. By the 1970s, aggressive development in the United States necessitated the implementation of regulatory measures to protect the environment. Since then, the debate has focused not on whether the environment should be protected, but how comprehensively that regulatory protection should extend. Nowhere has this debate been more evident than with the federal Clean Water Act (CWA) and the definition of “waters of the United States” (WOTUS).

Groundwater governance in the United States: A mosaic of approaches

Groundwater is an important water supply for meeting municipal, industrial, and agricultural water demands and for supporting riparian and other ecological systems in the United States (U.S.). Effective groundwater governance is therefore crucial to the wise use of this largely non-renewable resource (recharge rates are slower than extraction rates). While minimum, federally-established drinking-water quality and water-discharge regulations do exist, the framework of the laws and regulations governing groundwater use in this country is highly decentralized.

Influence of grey water on physical and mechanical properties of mortar and concrete mixes

This project aims to evaluate the potential of reused grey water in concrete and mortar in order to preserve fresh water for drinking purposes. Using both Treated Grey Water and Raw Grey Water (TGW and RGW, respectively) led to a significant increase in the initial setting time and a decrease in the concrete slump value.

Decentralized Groundwater Governance and Water Nexus Implications in the United States

The interconnectivities of groundwater to food, energy, and the climate are addressed to various degrees at the state level. Groundwater governance in the United States is decentralized, resulting in considerable variations in state practices. This article, published in Jurimetrics and written by Sharon B. Megdal and Jacob Petersen-Perlman, reports on two state-level surveys and three regional case studies conducted to better understand groundwater governance strategies and practices. The article also relates the results of these research efforts to food, energy, and climate.

Findings and lessons learned from the assessment of the Mexico-United States transboundary San Pedro and Santa Cruz aquifers:

Groundwater, the "invisible water," is difficult to assess, manage and govern for many reasons, mostly due to the unknown quantities of the resource. Political boundaries dividing groundwater aquifers make assessment even more challenging. This article focuses on lessons learned from the hydrologic assessment of the Transboundary San Pedro and Santa Cruz aqufiers. The authors conducted the work in two phases: (1) laying the groundwork and (2) implementation.
