Groundwater Tips

Rain Gardens

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 [...]

Put Rainwater to Good Use

In times of drought, a rain garden is one way to put what rain we do receive to good use. A rain garden is a landscaped area of low-maintenance native plants designed to collect and use rainwater. They require less maintenance and fewer chemicals than lawns. Instead of allowing rainwater to flow from your home [...]

Urban Runoff

Earth Gauge Video is available for this tip!
When the snow melts or the rain falls, where does the water go?  On a typical city block – with pavement and rooftops – more than half runs off into storm drains instead of soaking into the soil. On the way to the storm drain, water picks up [...]

New York Groundwater

Did you know that groundwater provides one quarter of New Yorkers with their drinking water, totaling around 900 million gallons of water dailyWhen rain falls, some of the water ends up in lakes and rivers, some of it is used by plants, some of it evaporates back into the atmosphere, and some seeps through the [...]

Guard Your Groundwater

When rain falls, some of the water ends up in lakes and rivers, some of it is used by plants, some of it evaporates back into the atmosphere, and some seeps through the ground into aquifers – large, natural underground water storage areas.  We call the water stored in aquifers “groundwater.”  It is an important [...]

Affected Amphipods

What looks like a shrimp, is related to crabs and lobsters, and is found only in small freshwater springs in Rock Creek Park?  Hay’s Spring Amphipod – a tiny, blind, bacteria and fungus-eating crustacean.  Both Hay’s Spring amphipod and Kenk’s amphipod are found only in the District of Columbia, surviving among wet leaves in areas [...]

Drink Up

Americans fill-up one billion water glasses from the tap each day, and water utilities treat more than 34 billion gallons of water daily.  While our tap water is generally safe, naturally-occurring pollutants and pollutants from humans and animals can impact drinking water quality.

Permeable Pavers (Chesapeake Bay)

In the 1990’s, the amount of impervious surface – paved areas such as roads, driveways, and sidewalks – increased five times faster than the population in the Chesapeake Bay Watershed! By 2000, more than 860,000 acres of land (about 1,343 square miles) was covered in pavement, and it is expected that an additional 250,000 acres [...]

Reducing Runoff

When rain falls on natural areas, it slowly soaks into the ground where it recharges groundwater supplies that eventually feed some rivers and streams. In urban areas, however, large amounts of pavement cause rainwaterand snowmelt to run off roads, driveways, and sidewalks quickly. Instead of seeping into the ground, this water is carried through storm [...]

Don’t Lose the Litter

Forests floors naturally accumulate a layer of litter, which can include twigs and sticks, leaves, evergreen needles, and other materials. This litter is an important part of the forest, as it provideshomes andnutrients for various plants and animals. The litter also helps to slow the flow of rain water and snowmeltover land, allowing it to [...]

Guard Your Groundwater (New Hampshire)

About half of the U.S. population gets their drinking water from groundwater. Not only does groundwater quench our thirst, but it is also important in protecting water quality and quantity in surface rivers and streams – during drier times, these waters are derived almost completely from groundwater supplies.

Climate Fact: Discharges and Dead Zones (Topeka, KS)

Since 1910, overall precipitation in the lower 48 states has increased by ten percent, and the region with the largest increase in rainfall is the Mississippi River basin, which includes the Kansas River.  Because of fertilizer use on farms, lawns, and gardens in the basin, wet years mean that more nitrogen (an ingredient in fertilizer) [...]
