Ph.D in Organic Chemistry

Actively involved in Science Education

Lifelong interest in Ecology and Environmental Science

NOT an expert on Watersheds! I’m sharing this as a concerned citizen

What is a Watershed?

Simply put, it is a geographic region drained by a particular creek, stream, or river.

Usually defined by the largest river that drains into a body of salt water.

A simple thought experiment..

When a drop of rain falls where does it go on its journey back to the sea? The Pacific? The Atlantic? Gulf of Mexico? Long Island Sound?

Where would its “neighbor” go?

Now, consider 4 million neighbors!

The geographic region defined by the collective drainage of these raindrops defines a watershed.

Size varies widely, the Mississippi drains millions of square miles, our local watershed about 15 square miles

A Simple Watershed

Does all the water return to the sea?

Eventually, yes…

However, it may seep into the ground and become part of an aquifer. The water in aquifers may stay underground for days.. Or years.. Or even centuries

The water may also evaporate back into the atmosphere

Now, lets add some complex features…

Who Cares??

We all should…

We need fresh water to drink

We need fresh water for growing food

We need fresh water for the plants and animals that are part of our environment

The Value of a River

Rivers drain away excess water, ie flood control

Rivers provide fresh water habitat

Rivers provide a source of water for the rich Riparian biomes surrounding them.

“Riparian” means essentially near a river. Riparian zones are often the most diverse habitats in a given region, a linear “oasis” if you will.

Rivers are important for commerce and leisure activities

Riparian and Salt Marsh Habitat

Great variety of plants and animals

Aesthetically pleasing

Ecologically critical as a source of food and it functions as an important waste control system - natural biofiltering

Salt marsh habitat is critical for biofiltering and as a home to a diverse collection of plants and animals

The Rooster River

Small, only about 10 miles long, entire watershed is only 15.3 square miles

Ash Creek, our local salt marsh estuary, is the outlet of the Rooster River

Tidal flux goes up to just past the Mount Grove cemetery

So .. Lets look at a map!

What Affects our Watershed?

Natural factors like total rainfall and geography

Climate: hot and wet? cold and dry?

Tidal flux

Agriculture and Landscaping use

Urbanization

Industrial Pollution

“They Paved Paradise and Put up a Parking Lot”

One major effect of urbanization is simply the covering of the ground with less permeable harder surfaces

Creates much faster moving runoff

Keeps water from seeping into the soil

Exacerbates erosion

Depletes the underground water supply

Pollution

Point Pollution: A well defined release point for pollutants. Sewage Treatment plant, Factory, Research Facility

Non Point Pollution: agricultural spraying, landscape maintenance, vehicle emissions, dry deposition from remote sources

Myriad of harmful effects on our local watershed - exposure to toxic materials, algal blooms, long term degradation of the habitat

Pollution Information…

The internet has made it much easier to find information

The internet has made it harder to validate information!

Look for reliable, long standing sources but keep an open mind

What Can I DO?? (a lot actually!)

Work to encourage honest and thorough pollution reporting

Support Remediation Efforts

Hold Politicians Accountable

What Can I do? At Home?

Replace high maintenance lawns with native vegetation and mulch

Compost your lawn and garden waste, e.g. leaves, grass

Use porous materials for driveways & sidewalks

Sweep driveways, sidewalks & roads rather than using a hose

Avoid use of pesticides

Pick up after pets

Use, store, and dispose of chemicals properly (in Bridgeport residents can bring their toxic chemicals to the transfer station on Asylum street once a year)

Use a car wash instead of washing car at home

Prevent storm drain dumping

Why?
