As he crossed the Pacific Ocean, what Charles Moore discovered in 1997 (and shortly thereafter was named the Great Pacific Garbage Patch), exists within the confines of the North Pacific subtropical gyre. There are five major ocean gyres around the globe that have existed and evolved with the shifting of the tectonic plates since the beginning of time. Formed by global wind patterns and the forces created by the Earth’s rotation, ocean gyres have a tendency to collect debris – which up until modern times has consisted of natural material.

Because of its unique geology and hydrology, the Hengill region in Iceland, provides a remarkable view of the past in the newly hewn volcanic landscape with fresh, shallow soils. It also offers a peek at the future, as scientists warmed streams and enriched them with nutrients to study the effects that global climate change could have on rivers around the world.

The measurement of ammonia is critically important in applications such as wastewater, where treatment plants are required to provide a laboratory measurement of ammonia concentration. The ammonia gas-sensing ion selective electrode (ISE) is an EPA approved method of determining ammonia concentration for compliance reporting.

The measurement of nitrate is important in applications such as #wastewater, drinking water, agriculture, and food/beverage. One EPA approved method of determining nitrate concentration for compliance reporting is the nitrate ion selective electrode (ISE).

The Mississippi River watershed covers more than 37% of the continental United States (2,981,076 km2). The river itself provides drinking water for over 18 million people and passes through 10 states. The source of the “Mighty Mississippi” begins as a meager creek in Lake Itasca, Minnesota, but the river grows as it flows, all the way to the Mississippi River delta in Louisiana and its final destination in the Gulf of Mexico.

The expedition and study, Paddle On, was conducted to obtain a baseline analysis of Mississippi River water quality so that future studies can be compared against it. Alyssum Pohl (@AlyssumPohl), with a B.S. in Biology and M.A. in International Environmental Policy, solo kayaked the entire length of the river from source to sea documenting plastic waste and measuring...

Harmful algal blooms (HABs) have increased in both frequency and intensity in the last two decades, driven by climate change and activities that introduce growth-stimulating nutrients into waterways. Concerns related to freshwater HABs range from the innocuous but unpleasant taste and odor compounds that find their way into drinking water, to fish kills and algal toxins that are harmful to human health. These consequences have increased the pressure upon researchers, watershed managers, water utility operators and public health professionals to closely monitor for the onset of HABs and prepare to respond. Dr. Stephanie A. Smith provides a basic overview of bloom-forming algae, including a review of the toxins that are of human health concern.

Concentrated animal feeding operations (CAFOs) are colossal facilities where thousands of animals are raised for consumption. In the United States, North Carolina is one of the top players when it comes to production of swine and poultry by using these types of operations. But, with that high ranking comes high risks for North Carolinians.
