Understanding Schuylkill River Bank Plastic Bottle Trash

The Schuylkill River from the Girard Ave Bridge to Fairmount Dam has a significant plastic bottle accumulation along the West bank (link, link). Geomorphology  can help us understand why.

The Schuylkill, like many rivers, meanders with numerous bends as it makes its way from the headwaters to the Delaware River.  These bends play an important role in the shape and life of the river. Bend outside banks tends to erode while the inside banks tend to form point bars.

Let’s take a look at the Schuylkill from just upriver of Girard Ave Bridge to Fairmount Dam.

You can see 2 bends in the River, the bend near Girard Ave Bridge and the bend by Boat House Row.  The mud flats on the West bank of the River by the Girard Ave. Bridge have been formed by point bar type deposition of sediment on the inner bank of the River. These mud flats have proven to be an effective natural plastic bottle trash trap, as shown in this photo of the West Bank taken on 4/11/15.

Most of these bottles have been carried by stormwater to the Schuylkill and have flowed downriver. During high flow periods some bottles accumulate along the inner curve of the River bends and get stranded when the River flow recedes.

The Girard Ave mud flats are an excellent location to monitor the Schuylkill River plastic trash  load over time. The Schuylkill Navy has cleaned approximately 1,300 feet of the West bank so that future plastic accumulation rates can be measured at this location.

Plastic Debris along Schuylkill Banks in Fairmount Park

The Schuylkill River through Fairmount Park is one of Philadelphia’s treasures.  Unfortunately, upstream stormwater runoff carries trash to the Schuylkill River,  where some gets caught on the River banks while the rest continues to flow downriver to the Delaware River and Bay.

This Schuylkill River bank trash survey was conducted on the West bank from the dam to Girard Ave bridge on 4/7/15.

There is a significant quantity of plastic debris along the shore line caught in the vegetation along the bank .

 

Tidal Schuylkill Banks Trash Assessment @ Bartram’s Garden

United By Blue is a wonderful local Philadelphia company that is working hard to cleanup creek – river trash. Bartram’s Garden, along the Schuylkill River, has been one of their  cleanup sites so I decided to check out the bank trash for myself.

I 1st visited Bartram’s  on 8/10 and made a repeat visit on 9/3. Here is a slide show of my bank trash findings along the Bartram’s Garden’s 3,000 foot stretch of tidal Schuylkill River bank.

Yes Philadelphia, in addition to the Tacony-Frankford Creek, we have a Schuylkill River trash problem. Plastic bottle-food wrappers-food container litter is being carried to the River by run-off during rain storms upstream of Philadelphia and in the City.

Our plastic trash is building up on our shore lines and in the N Atlantic gyre.

Plastic street litter is a serious water pollution problem that we must through product controls, litter prevention, street cleaning and waterway cleanups. Right now we are losing the fight against marine debris.
