Wetland Values

There is a tremendous diversity in wetland types and wetland vegetation in the United States, caused primarily by regional, geologic, topographic, and climatic differences. Wetland hydrology, a primary driving force influencing wetland ecology, development, and persistence, is as yet poorly understood. The interaction between groundwater and surface water and the discharge–recharge relationships in wetlands affect water quality and nutrient budgets as well as vegetative composition. Hydrologic considerations necessary for an improved understanding of wetland ecology include detailed water budgets, water chemistry, water regime, and boundary conditions. Wetland values are often based on perceived wetland functions. These hydrologic functions include (i) flood storage and flood-peak desynchronization, (ii) recharge and discharge, (iii) base flow and estuarine water balance, and (iv) water-quality regulation. Expanded research and basic data collection focussed on wetland hydrology and its relation to wetland ecology are needed to identify and quantify the hydrologic functions of wetlands.

The 1960S

By the 1960s, the failures of research and cooperative pragmatism to control Great Lakes pollution were becoming painfully evident. In 1972 Canada and the United States signed the Great Lakes Water Quality Agreement. The agreement was groundbreaking in its focus on cleaning up existing pollution and preventing new pollutants, but the International Joint Commission has no authority to force the two nations to implement recommendations. Therefore, when Canada or the United States refuses to abide by the Great Lakes Water Quality Agreement (in its various revisions), very little happens in response—besides calls for more research.

Ohio River Valley

Source water quality is of major concern to all drinking water utilities. The accidental introduction of contaminants to their source water is a constant threat to utilities withdrawing water from navigable or industrialized rivers. The events of 11 September, 2001 in the United States have heightened concern for drinking water utility security as their source water and finished water may be targets for terrorist acts. Efforts are underway in several parts of the United States to strengthen early warning capabilities. This paper will focus on those efforts in the Ohio River Valley Basin.

Spatio Temporal

Hydrosocial spatio-temporalities—aspects of water belonging to space, time, or space-time—are central to water governance, providing a framework upon which overall hydrosocial relations are constructed, and are fundamental to the establishment of values and central to socio-cultural-political relationships. Moreover, spatio-temporal conceptions may differ among diverse governing entities and across scales, creating “variability” through ontological pluralism, as well as power asymmetries embedded in cultural bias. This paper explores spatio-temporal conceptions related to water quality governance, an aspect of water governance often biased toward technical and scientific space-time conceptions. We offer examples of different aspects of spatio-temporality in water quality issues among Tribes in the United States, highlighting several themes, including spatiotemporal cycles, technological mediation, and interrelationship and fluidity. Finally, we suggest that because water is part of a dynamic network of space-times, water quality may be best governed through more holistic practices that recognize tribal sovereignty and hydrosocial variability.

Moving Bed

Waste discharged into the environment (air and water) needs to meet the expectation of environmental quality standards. One method that has been widely studied and to be used in maintaining water quality is a combination of the Moving Bed Biofilm Reactor (MBBR) method. With the Dimensions database, in the last ten years (2010-2020), it is known that there are 373 journals regarding MBBR for wastewater treatment. Furthermore, a bibliometric analysis was carried out with data from 2017 to 2020, using visualization from Vosviewer to determine the development of research on MBBR. Indonesia is in 10th place, contributing five articles on MBBR. Some other countries conducting the most research on MBBR include China, the United States, Iran, India, and Germany. The Journal that publishes the most research on MBBR is Bioresource Technology. The author who has done the most research on MBBR is Olav Vadstein, by the issuance of four articles. Meanwhile, the institutions that write the most research on MBBR are the Norwegian University of Science and Technology and the Technical University of Denmark. Another combination of data-driven systematic literature review (SLR) is needed to complement the bibliometric analysis of the MBBR study for wastewater treatment.
