Water and Health: Where Science Meets Policy
Managing Water as One: Breaking Down the Silos to Advance a Sustainable National Water Policy
Imagine a world where water is viewed, managed, and valued as one resource. A world where the silo thinking that has kept clean water, drinking water, stormwater, and water reuse interests segregated erodes - and a movement toward meeting future challenges on a watershed basis, with a focus on sustainability and green cities, emerges in its place. Changing the water paradigm - this is the vision of the Clean Water America Alliance (Allianc

Oxygenation and mixing are required in many municipal and industrial wastewater treatment plants (WWTPs) to improve processing and shorten treatment durations. WWTPs often use mechanical aerators to both oxygenate and mix wastewater. However, much more aeration is needed to thoroughly mix than oxygenate the wastewater. Excessive horsepower (HP) usage for mixing increases electrical grid-power consumption, operational costs and greenhouse gas emissions.

The increasing incidence and durations of toxigenic Freshwater Harmful Algal Blooms (FHABs), threaten human and animal health, aquatic-ecosystem sustainability and economies. Successfully confronting the risks of FHABs requires effective and environmentally sustainable methods for bloom prevention. The U.S. Environmental Protection Agency (EPA) has not established FHAB-prevention policy. Relevant EPA and other Agency activities are heavily weighted toward limiting nutrient input to freshwater through soil conservation and watershed management practices.

The increasing incidence and durations of toxigenic FHABs threaten human and animal health, aquatic ecosystems and economies. Climate change is partially driving the increase through rising temperatures, excessive nutrient input to waterbodies during severe stormwater runoff, and water stagnation during prolonged droughts. Prolonged expenditures of $1B+/yr on watershed management failed to halt the increase. Environmentally sustainable within-waterbody management solutions are needed to suppress FHABs.

You often need to reach across scientific disciplines, engage the public, get legislation enacted, and interact with agencies and industry to solve some of the world’s greatest problems. This presentation will describe the ongoing effort to protect health and aquatic ecosystems from the looming crisis of toxigenic freshwater harmful algal blooms (FHABs). FHABs are rapid and massive expansions of phytoplankton populations, particularly cyanobacteria, many of which produce some of the most potent toxins known.

The increasing incidence and durations of toxigenic Freshwater Harmful Algal Blooms (FHABs) threaten human and animal health, aquatic-ecosystem sustainability and economies. Successfully confronting the risks of FHABs requires ecologically benign and sustainable methods for bloom control. The current study evaluated the ability of solar-powered circulation (SPC) to suppress FHABs. Municipal personnel at three nutrient-enriched, source-water reservoirs collected planktonic-density data sufficient for assessing the efficacy of SPC for FHAB suppression.

Increasing challenges to water quality endanger health, ecosystem and economies. Solar powered circulation (SPC) solves water quality problems in freshwater, potable water, wastewater through ecological processes while reducing electrical-grid and chemical dependence.
Freshwater harmful algal bloom (FHAB) incidence is increasing in part due decreasing water flow rates. FHAB toxins, among the most potent known, endanger health in drinking and recreational waters. SPC suppresses FHABs and increases biological diversity without grid power or algaecides.

U.S. Congressional legislation is needed to establish a National Freshwater Harmful Algal Bloom (FHAB) Research Plan. The U.S. Environmental Protection Agency (EPA) has purview over all U.S. freshwater bodies, but has not made regulatory determinations or established Federal policy due to FHAB data deficiencies. A clear Congressional directive, the proposed Freshwater Harmful Algal Bloom Act of 2009 (FHAB Act), is needed to establish a National FHAB Research Plan for obtaining FHAB data.

The role of fisheries in promoting cyanobacteria blooms in Oregon lakes was evaluated by (1) targeted surveys of lakes with a range of morphometric, chemical, and biological attributes, (2) examination of intended and unintended manipulations of fisheries in several lakes, and (3) paleolimnological and modeling analyses of selected lakes with introduced fisheries in the 20th century.
