George W. Bush On President Trump, Putin, Religious Freedom, Immigration (Exclusive) | TODAY


The new book “Portraits of Courage” combines former President George W. Bush’s appreciation for the sacrifices of our veterans with his love of painting. Bush discusses his inspiration for the book with TODAY’s Matt Lauer, and highlights the differences in the first month of Donald Trump’s presidency with his own time in office, including his thoughts on Putin, the need for a free press, the impact of religious freedom on politics and more.

Using river & lake invertebrates and other techniques to assess water quality in Britain and Ireland

Using river & lake invertebrates and other techniques to assess water quality in Britain and Ireland


The Loughs Agency undertakes river water sampling on a routine basis within the Foyle and Carlingford hydrological catchments. The biological and chemical monitoring of freshwaters assists in determining the concentration of harmful pollutants in the aquatic environment. This pollution monitoring has several key objectives:
1. to identify potential threats to fish health and aquatic ecosystems;
2. to inform the public about the quality of the aquatic environment and to raise public awareness of environmental issues;
3. to provide inputs into policy-making decisions;
4. to assess the efficacy of pollution control measures;
5. to identify trends in pollution and to identify future problems.

The following chemical parameters are analysed in the Loughs Agency laboratory:
• Ammonia (NH3)
• Total Phosphorus (PO4)
• Total Suspended Solids (TSS)
• Biochemical Oxygen Demand (BOD5)

Each of the 105 sites is sampled to assess for biological indicators using the 3 minute kick sampling method. A sample is obtained from the watercourse and stored in a plastic container for subsequent laboratory analysis. Staff at the laboratory then undertake detailed macro invertebrate identification and record the results for subsequent determination of a BMWP score to indicate the level of water quality.

Water Quality Worldwide


Ahead of World Water Day, Gallup examines how satisfied the world’s citizens are with the quality of their water and finds that people in sub-Saharan African nations are the least likely to be satisfied with their water’s quality.

Water Quality and Wastewater Treatment, Environmental Engineering Graduate Student Coy McNew

Water Quality and Wastewater Treatment, Environmental Engineering Graduate Student Coy McNew


The overall goal of graduate student Coy McNew’s Ph.D. Research at Vanderbilt University is to gain a better understanding into the behavior of engineered nanomaterials (ENM) in the subsurface environment, including an increased understanding of the retention of these potential pollutants in porous media. This should lead to improved means of water and wastewater treatment containing ENM and subsequently, increased public health – as well as a better understanding of the risk these ENM may pose to other biological systems in the natural environment
Coy works under the direction of Dr. Gene LeBoeuf in the Vanderbilt University School of Engineering, and is pursuing his Ph.D. In Environmental Engineering.
The unique physicochemical properties of engineered nanomaterials (ENM) make them attractive for application in a number of advanced technologies; however, these same properties raise concerns about their impacts to ecosystems and human health. With the impending mass production and increased number of applications of these ENM, there will be ample opportunities for the ENM to enter the natural environment. Several studies have predicted the possible toxicity of aqueous ENM aggregates to biological systems and in order to minimize the risk of these possible contaminants we must improve our understanding of the fate and transport of these particles in the natural environment. Coy’s research looks at how these ENM interact with different types of natural organic matter (NOM) that are ubiquitous in the subsurface environment. By using a quartz crystal microbalance (QCM) I can directly measure the deposition and subsequent detachment of these ENM onto bare silica surfaces as well as surfaces altered by adsorbed NOM. In doing so, I can investigate what roles the fundamental structure and physicochemical properties of this attached phase, or adsorbed, NOM play on the attachment and detachment of ENM.

It is drop-rated, drop-tested to one meter on concrete, waterproof, features military spec cable connectors, and can be used in any lighting condition. This rugged design will provide you accurate data in any weather condition year-round. The ProDSS is a true field instrument. The ProDSS is not only an accurate, rugged, and reliable instrument, but it is also very easy to use. For starters, the ProDSS can easily be held in one hand. Combined with the one-cable design, the instrument is very convenient to use in the field.

The ProDSS is designed to meet the needs of any water quality application, such as aquaculture, ground water, surface water, waste water, and coastal applications. Whether you’re spot sampling, conducting a low-flow sampling session, profiling, or measuring samples in a lab, the ProDSS will make collecting accurate data easy and efficient. We guarantee the accuracy of the measurement through rigorous specification testing during development and final testing every component of the system, including the handheld, cable, and sensors before they leave our factory.
