What is a nitrogen footprint and why is it so important?  Well, just like a carbon footprint, a nitrogen footprint approximates how much nitrogen your daily activities produce over a period of time. Nitrogen is important because it builds our DNA, amino acids and proteins that grow the tissues of all living things.  Farmers use [...]

Animals like frogs and turtles are waiting out winter by submerging or freezing. As spring temperatures rise and their prey becomes active, reptiles and amphibians will make use of small pools of melt water called vernal ponds. These temporary pools are the breeding grounds and also the feeding grounds for many animals. As the spring [...]

Are you spring cleaning? Cleaning products like soaps and detergents keep our clothes, dishes and floors looking their best.  But some of the chemicals found in these products impact water quality in our streams and rivers. Many soaps and detergents use phosphates as cleansers. When soapy water goes down the drain, it ends up at [...]

Each year, about 1.4 million metric tons  of nitrogen reach the Gulf of Mexico from the Mississippi River and its watershed.  Much of this pollution comes from rain water runoff from roadways, lawn and gardens, sewage treatment plants and agricultural areas.  The Mississippi River provides essential water for fishing, floating, boating and swimming, but too [...]

Each year, World Wetlands Day is celebrated on February 2nd. Wetlands come in many forms and go by many names – estuaries, bogs, mangrove swamps, vernal pools, marshes, riparian wetlands, cypress swamps, playa lakes and more! Wetland areas improve water quality, provide flood protection and support tons of fish, wildlife and plants. If you’ve been [...]

Did you know that the Mississippi River provides drainage for 41 percent of the continental United States?  This means that if a single drop of rain falls anywhere in this area, which includes all or part of 31 states and two Canadian provinces, it becomes a part of the Mississippi River Watershed.  The fate of [...]

Nitrogen and phosphorus are part of healthy aquatic habitats. These nutrients support the growth of underwater plants that provide oxygen and habitat for fish and other animals. They also support algae growth, which is a source of food for many fish and shellfish. Aquatic habitats can become unbalanced, however, when too much nitrogen and phosphorus [...]

When we think about oil pollution in estuaries and along the coasts, many of us think of the giant oil rigs and big spills like the Deepwater Horizon spill last year. But most oil pollution is generally the result of small spills and leaks from boats and ships. When oil comes into shallow waters and [...]

When it rains, what goes down the storm drain? As rain water flows over yards, driveways and city streets, it picks up pet waste, fertilizers and pesticides, oil from cars, trash and other pollutants. It’s tempting to think that storm water visits the local waste water treatment plant, but in most communities water that goes [...]

Trash and chemicals that end up in the street drain directly into our waterways. For example, old motor oil that is poured down a storm drain on the side of the street will wind up in Tampa Bay. Fertilizer and pet waste that do not get absorbed by lawns also flow into the streets, down [...]

Did you know that a typical city block generates more than five times as much rainwater or snowmelt runoff as a forested area of the same size?  This is because rooftops and pavement do not allow water to soak into the ground like forests, wetlands and grasslands do.  Instead, rainwater and snowmelt runs off pavement [...]

San Juan Bay provides a number of resources to Puerto Ricans, including commercial ports, beaches, recreation areas and historic areas. The Bay, which is partially enclosed by surrounding marshes, mangroves and land, has a limited ability to flush water out, making it particularly susceptible to accumulation of pollutants. Viewer Tip: With so many water resources [...]

Rain keeps our forests in the Pacific Northwest green. Raindrops also wash off our roofs, across lawns and down onto streets and parking lots, carrying chemicals from our yards and automobiles to local waterways. These chemicals are absorbed by small organisms that are eaten by fish, birds and animals and can disrupt reproduction and ability to fight [...]

A recent study by the U.S. Geological Survey found elevated levels of nitrogen and phosphorus in many streams and groundwater supplies across the country. Elevated levels were most often found in streams near agricultural areas, particularly in the Northeast, Midwest and Northwest, as well as near urban areas. In many cases, concentrations of nitrogen and [...]

The “Drip by Drip” Oil Spill Did you know that a quarter of a million gallons of oil are being “spilled” in the Northeast each day? Where does this oil come from? Us, our families, friends and neighbors! Some do-it-yourself oil changers dispose of their motor oil in the trash or pour used oil down [...]

Did you know that you can help the Gulf of Mexico without traveling beyond your driveway? Our region is part of the Mississippi River watershed, an area of land that drains rain water and river water into the Gulf of Mexico. When it storms here, rainwater carries pollutants like fertilizer from farms and lawns, motor [...]

Residential driveways can account for up to 15 percent of the total paved area in a city or state. These paved surfaces are “hot spots” for accumulation of pollutants like motor oil, antifreeze and yard care chemicals. During a storm, rain water picks up pollutants from paved areas and heads to the storm drain, which [...]

How much hazardous waste does the average American household accumulate in one year? Ten pounds? Fifty? Actually, the typical home accumulates up to 100 pounds of household hazardous waste in just one year! Think of paints, pesticides, cleaning supplies, oil, antifreeze and other products that hide away in the basement, garage or shed. These products [...]

Rain gardens can cut down on the amount of pollution reaching creeks and streams by up to 30 percent. A rain garden is a planted depression that allows rainwater runoff from artificial urban areas like roofs, driveways, walkways and lawn areas to be absorbed. This reduces runoff by allowing storm water to soak into the [...]

The Texas Commission on Environmental Quality estimates that Texans discard 1.5 million computers annually and depend on an average of six wireless (battery-powered) products daily! Computers, electronics and batteries contain metals like nickel, aluminum, mercury and lead. When these items end up in landfills, metals may vaporize into the air when burned or leach into [...]
