In this guided review, you will learn about the different water quality parameters, the ways they interact with one another, and the work being done to manage water quality. This review aims to identify instances of impaired water quality and its impact on nearby communities.

Students will investigate the quality of water by collecting data on parameters including temperature, salinity, pH, dissolved oxygen, turbidity, nitrates, and nitrites. They will determine what it means for water to be "safe," and identify what causes can alter water quality.

Harmful algal blooms, or HABs, occur when colonies of algae - simple plants that live in the sea and freshwater - grow out of control and produce toxic or harmful effects on people, fish, shellfish, marine mammals and birds. The human illnesses caused by HABs, though rare, can be debilitating or even fatal. Ranging from microscopic, single-celled organisms to large seaweeds, algae are simple plants that form the base of food webs. Sometimes, however, their roles are more sinister.

The quality of water we use and drink determines in large part quality of our lifes. Clean water is essential to the health and well-being of people preserving the integrity of the natural environment and sustaining economies.

Water is refreshing, hydrating, and invaluable to your survival. But clean water remains a precious and often scarce commodity - there are nearly 800 million people who still don't have regular access to it. Why is that? And how can you tell whether the water you have access to - whether from a tap or otherwise - is drinkable?

Management of nitrogen loading into the watershed is a feasible proposition even with the likely further urban expansion on the northern shore of the Lake. The consequences of future nitrogen loadings resulting from population growth on the north shore of Lake Pontchartrain can be compensated for by rather rudimentary sewerage treatment of existing non-point sources, from treatment or diversion of pumped urban runoff, and by sealing the leakage of water passing through the Bonnet Carre Spillway.

The Mississippi River drains water from 31 different states, where rain and snowfall make their way south and make the river swell in Louisiana." This video investigates the Bonnet Carre Spillway, a flood control structure designed to prevent flooding from the Mississippi River

We know that average sea levels have risen over the past century, and that global warming is to blame. But what is climate change doing to the saltiness, or salinity, of our oceans? This is an important question because big shifts in salinity could be a warning that more severe droughts and floods are on their way, or even that global warming is speeding up. Now, new research coming out of the United Kingdom (U.K.) suggests that the amount of salt in seawater is varying in direct response to man-made climate change.

First Nations reserves across Canada struggle to access clean drinking water from their taps. We explain why this problem has persisted and what the Trudeau government is doing about it

Watershed concepts are vital to include in any conversation about water pollution. This animated video explains "how watersheds work in the United States and how they impact us on many levels."
