A wastewater plant may not be the first place that comes to mind to look for birds, but many birders know the secret; They can prove to be quite good places to find gulls and waterfowl, often unusual in timing or species. Our local plant, operated by Veolia, is known as a great place for ducks which can be found in great numbers on the ‘polishing’ ponds adjoining the river.   Polishing ponds are the very last stage of a series of processes that separate solids from water and then cleans the water enough so it can be discharged to the Delaware River.

The wastewater that travels through sewers and enters the plant is called ‘influent’, and the first step is a mechanical bar screen that removes rags, paper, and other articles larger than a centimeter. Those screenings go to a landfill.   The ‘effluent’ (wastewater that exits) is then channeled into a grit chamber where the velocity is slowed down and the heavier grit, sand, and gravel settle out and are removed.

After leaving the grit chamber the wastewater enters a primary clarifier, where velocity slows again and additional suspended matter, typically organic, settles to the bottom forming a sludge layer. Greases and oil and other floating matter, rise to the top and form a scum layer.   Slow rotational scraper blades move the sludge to a hopper at the bottom of the clarifier and a skimmer on the surface directs the scum to another collector.

Now comes the secondary treatment; the wastewater flowing out of the primary clarifier goes into aeration basins where it is exposed to living organisms and bacteria that consume most of the organic matter in the wastewater. The water is bubbled to supply the microorganisms with the oxygen they need. In about 3 hours, the time it takes for the water to pass through the aeration tank, most of the organic matter has been consumed. (photo of aeration basin)

The secondary clarifiers receive the mixed liquor (wastewater and microorganisms) from the aeration tank. Here the scum on top is once again skimmed off and the activated bacteria that has settled to the botton is scraped into a hopper and then returned to the aeration chambers. The microrgasims will have increased through reproduction, so the excess are removed as sludge. The clear water leaving this basin now goes for Tertiary treatment. Here we have a group of Ring-billed Gulls enjoying the ‘fruits’ of Veolia’s efforts at the clarifier!

Throughout this phase, removed sludge is taken to an anaerobic chamber which gives off methane as it further digests the sludge. The methane is ‘flared’ and the final digested sludge is dewatered. It now looks and smells like humus and can be sold for non- edible application (e.g. golf courses).

Tertiary treatment happens in the large Polishing Ponds, the desired destination of avid winter birders. It takes about 3 days for the water to move through these ponds, where further settling and bacterial action take place. As a final treatment, the water is given a dose of bleach before it is sent into the Delaware River. The effluent entering the Delaware is tested daily for fecal coliform and other pollutants.   It is discharged through a pipe in the middle of the river at a depth of approximate 35 ft.

We spent the final portion of our tour looking at a variety of ducks in the polishing ponds. In most places in New Castle County, the waterfowl have already migrated North, but here in this protected spot, we had a nice show.   On our trip, we had far fewer ducks than can be found in mid-Winter, but we had a nice variety; Gadwall, Mallard, Northern Shoveler, Ring-necked Duck, Lesser Scaup, and Ruddy Duck . We counted 23 species of birds for the day at Veolia Waterwater Treatment Plant – not bad for a place where most folks just want to hold their nose.

The Teen Naturalists kicked off 2017 by orienteering at French Creek State Park in Berks County, PA. This 7,339 acre park was logged repeatedly to make charcoal for the Hopewell Furnace, which operated until the late 1800s. The land was sold to the government in the Great Depression, and managed similarly to the national parks at the time, with the Civilian Conservation Corps building recreational facilities in the park. Today the park land is owned by the State of Pennsylvania and the National Park Service maintains the historic furnace as the Hopewell Furnace National Historic Site. This park is the largest contiguous forest between New York City and Washington D.C., known for the variety of wildlife and recreational activities, including more than 35 miles of trails.

French Creek State Park is also home to a permanent orienteering course. Orienteering is a sport that combines navigational skills and racing. Participants use a highly detailed map and a compass to move from point to point, trying to complete the course in the least amount of time. We were not that competitive, but we did enjoy the challenge of navigating ourselves through the course around Hopewell Lake.

After a quick introduction, the Teens began to familiarize themselves with the compass, map, and map legend. Orienteering maps are incredibility detailed – roads, fences, trails, streams, hills, depressions, rocks, vegetation, etc. are accurately located. The Teens oriented themselves from our starting point in the parking lot to “control #1”. We set off in that direction, searching for a post with an orange and white square at the top.

Each post had the control number and letter code on the marker post placard. The letter code is recorded for competitive orienteering, to prove you made it to that location.

We recorded the letters in hopes that they spelled a word upon completion of the course, but they unfortunately did not. Photo by Carrie Scheick.

The misty rain and fog provided us with beautiful scenery in the woods. We saw and/or heard multiple species of birds including Mallard, Pileated Woodpecker, Belted Kingfisher, Downy Woodpecker, Hairy Woodpecker, Carolina Chickadee, White-breasted Nuthatch, Brown Creeper, and Eastern Bluebird. There was a variety of fungi including puffball fungus, polypore fungus, and witch’s butter fungus. A Northern Watersnake took advantage of the mild temperatures and came out to say hello to us at the dam.

For most of the Teens, this was their first experience orienteering. They all enjoyed the challenge, as it gave additional purpose to their hike and time outdoors. This outing was a great way to kick off the year!

Thank you to everyone who joined Delaware Nature Society at both our inaugural Meal at the Mill, on Friday, October 14, and a special return of our Autumn at Abbott’s Festival, on Saturday, October 15, in final celebration of Abbott’s Mill Nature Center’s 35th Anniversary!

Guests at Meal at the Mill opened the event with a keg-conditioned cocktail from Dogfish Head Craft Brewery while mingling amongst hors d’oeuvres from Abbott’s Grill and touring Delaware’s only preserved, working gristmill. We then conjoined for a family-style, three-course seated dinner featuring seasonal vegetables and free-range chickens grown and raised on Delaware Nature Society’s own Coverdale Farm Preserve, with catering by Abbott’s Grill and menu pairings from Dogfish Head Craft Brewery. Dinner began with remarks by Brian Winslow, DNS Executive Director, Matt Babbitt, Abbott’s Mill Nature Center Manager, and Mark Carter, Dogfish’s Director of Philanthropy and DNS Board Member. Special guests of the evening included representatives of Delaware’s Division of Historical & Cultural Affairs (an owning partner of Abbott’s Mill), as well as Councilmembers from the Town of Slaughter Beach (which hosts DNS’s 109-acre Marvel Saltmarsh Preserve) and our hometown Milford City Manager. We amazingly sold out all seats for this event, and were very appreciative of the 93 guests who joined us under the stars to honor the history of Abbott’s Mill Nature Center and celebrate its bright future.

The next day, our Autumn at Abbott’s Festival brought out 350+ community members to enjoy the sunny skies at Abbott’s. This community-minded event highlighted the historic importance of Abbott’s to the lower, slower Southern Delaware culture, and provided several opportunities to explore the natural wonders preserved on our pet-friendly trails and 20-acre pristine pond. Last run in 2008, the event has historically featured a variety of artisan craft demonstrators, children’s activities, hay rides, and tours of our historic Abbott’s Mill. For the 35th we raised the stakes by adding in the Drift’n Kitchen and Heavenly Delights Concessions food trucks, a Dogfish Head Craft Brewery beer garden with lawn games, yoga sessions led by Lewes’ Free Spirited Foundation, aquatic touch tanks from Phillips Warf Environmental Center, guided SUP & kayak trips on Abbott’s Pond provided by Quest Fitness & Kayak, and live music from local musicians Margaret Egeln, the Clifford Keith Trio, and 3CNorth.

Both of these events would not have been possible without the support of all of our community sponsors as well as the 50+ volunteers and DNS staff who helped setup both events and took care of all of the behind the scenes work to make our event a success. Special thanks, as well, to our 35th Anniversary Presenting Sponsors: Dogfish Head Craft Brewery, National Wildlife Federation, and M&T Bank.

We would love to have all of you join us again as we continue celebrate Abbott’s Mill Nature Center’s 35th Anniversary throughout 2016. Please visit delnature.org/abbotts35 to explore the full celebration.

Additionally, as part the celebration, we are offering special pricing for Delaware Nature Society memberships at the individual adult and household/grandparent levels. Normally priced at $40 and $55 respectively, we are offering these memberships for $35 through the end of the year, and they can be purchased in person at the Abbott’s Visitor Center, or visit delnature.org/becomeamember to purchase online. A Delaware Nature Society membership includes the following benefits:

  • Membership valid for 12 months from purchase date
  • Free canoe rentals on Abbott’s Pond (*must call ahead to schedule)
  • Free admission to Autumn at Abbott’s Festival & Farm Fun Days at DNS’s Coverdale Farm
  • Free or reduced pricing on DNS programs
  • Priority buying window for DNS’s Native Plant Sale
  • Helping to preserve over 500 acres of wildlife habitat & hiking trails in Southern Delaware and over 2,000 state-wide
  • Discounts at local retail affiliates (including Quest Fitness & Kayaks and East Coast Garden Center)
  • Participation in the Association of Nature Center Administrators’ (ANCA) nation-wide reciprocal membership program

We are actively exploring the possibility of making these annual events at Abbott’s, and are thankful for the positive and constructive feedback we have received from everyone involved. Inaugural and/or returning events always present opportunities to learn and grow, and we will certainly incorporate your feedback when we begin to prep for next year. Thank you again for being a part of our year-long celebration of Abbott’s Mill Nature Center’s 35th Anniversary, and please continue to share your event pictures to our Facebook and Instagram pages, or through email at matt@delnature.org.

DANGER FALLS AHEAD: UNSAFE TO NAVIGATE BEYOND THIS POINT

The warning sign at the Raquette Falls Portage trailhead, photo by Carrie Scheick.

“DANGER FALLS AHEAD: UNSAFE TO NAVIGATE BEYOND THIS POINT” read a large white sign with bold red typeface. Next to the sign hung a very poignant visual display, in case the written warning wasn’t enough, the mangled remains of a canoe’s bow torn from its hull with seemingly the same ease as holiday wrapping paper. We sat on the banks of the Raquette River stretching after that morning’s 6-mile paddle and pensively eating our peperoni & cheese sandwiches, subconsciously trying to delay the inevitable that had denoted our trip as “extremely challenging.” If we can’t go down the falls, then we’d have to go up and over them on a 1.25-mile portage with 30-40 lb. backpacks and 60 lb. canoes in hand.

Delaware Nature Society’s Teen Naturalist program began in 2000 in its current form, but the Society has run a similar program, called the Junior Naturalists since the late 1960’s. The Teen Naturalists meet once per month for outdoor adventure, nature study, and volunteering for the environment. Each summer, the Teens take a week-long trip somewhere to be immersed in nature. In the past, the Teens have ventured to Ontario, Adirondacks 4 times, Laurel Highlands of PA, the PA Grand Canyon, and the Appalachian Trail in Maine and Maryland. The leaders for this year’s trip were Trudyann Buckley, DNS’s Education Intern, Carrie Scheick, DNS’s Teen Naturalist Program Leader, and Matt Babbitt, Site Manager at DNS’s Abbott’s Mill Nature Center.

This summer’s culminating trip for the Teen Naturalists was a 4-night/5-day wilderness paddling adventure on Long Lake and the Raquette River, located near the geographic center of New York’s 6-million acre Adirondack State Park (which is bigger than Yellowstone, Yosemite, Grand Canyon, Glacier, and Great Smoky Moutnains National Parks combined). Our first day was spent driving from DNS’s Ashland Nature Center to Long Lake, New York, a quaint town bustling with paddling, fishing, and seaplanes founded in the 1830’s. Gordon and Fran Fisher, longtime supporters of DNS who spend their summers in the area at their log cabin, were gracious enough to host our group that first evening for a relaxing swim and paddle in the lake, as well as warm company and a hearty homemade “last” meal.

Tuesday morning we woke up in high spirits to meet the local Raquette River Outfitters to receive our gear and hand off our van, and with it any last semblance of the millennial world of Snapchats, #hashtags, and fast food. After a quick briefing from the outfitters, we set out for a 9-mile paddle to our first campsite on the northern end of Long Lake. Boasting over 100 miles of shoreline of Adirondack wilderness, dotted with a few private homes and summer camps, Long Lake feeds into Tupper Lake and Saranac Lake via the Raquette River, and spans over 3,900 acres with a depth range of 15 – 40+ feet. The lake supports a healthy population of Large/Smallmouth Bass, Northern Pike, Brown Bullhead Catfish, Yellow Perch, and NY state record Brook Trout, and notably provides habitat for Common Loons, Common Mergansers, Black Bears, Adirondack Moose, Broad Winged Hawks, and Bald Eagles. Our first day paddle was spent adjusting our eyes to the very “we’re not in Delaware anymore” mountainous views, exploring coves for blooming American White Water-lilly and Cardinal Flower, quietly observing newly hatched families of Loons and Mergansers, and testing our paddling skills. We made it to camp by midafternoon, which gave us just enough time to pitch tents (and hammocks), take a refreshing dip in the cold lake waters, and enjoy our first backcountry couscous dinner. Being in bear country meant dinner was early and quick so we had enough daylight to collect everyone’s “smellables” along with our remaining food to set up a bear hang on a high branch 100+ feet from our campsite. Evening was spent around the campfire telling stories and filled with dreams of the dreaded challenge that laid ahead in the morning.

Wednesday morning was greeted with sunshine and oatmeal as we prepared for a 6-mile paddle to leave the still waters of Long Lake and begin our journey down the meandering Raquette River. Our shoulders were glad to meet the current and the shallower river waters meant we could say goodbye to the motorboats and enjoy true wilderness with wonderful viewings of fish, turtles, birds and underwater grasses. Nature observations aside, our attention was focused on finding the “the large rock with a sign on it, you can’t miss it,” as the outfitter had told us the day before. The rock was our queue that the infamous Raquette Falls were fast approaching and it was high time to pull of the river to find the portage trail. We were greeted by a scout group who was returning back to get the rest of their gear, who by disposition alone let us know the portage would be steep and demanding. After our aforementioned pepperoni sandwich lunch, we took several deep calming breaths, heaped on our backpacks and hoisted our canoes overhead, leaving behind the gear we couldn’t fit for a return trip. I took the sweep position on the trail, as the odd one in our 9 person crew, and was worried this portage would break our group like the mangled canoe hanging on the trailhead sign as I passed packs, pieces of gear, and even one of our canoes strewn along the sides of the trail. On the contrary, I was overwhelmed with optimism as I turned the corner to see all six of our teens forsaking the pairs we started in and self-selecting to team up and carry their boats together. Our fate was not that of the broken canoe, we had been forged even stronger by the portage through tears, tenacity, and teamwork.

We returned the trailhead to recoup our remaining gear, rounding our hike out at a solid 3.75-mile portage, recharged our internal batteries by the river’s calming rapids at the, and decided together to forego the campsite at the base of the falls and push downstream for more adventure. Pulling off the river at lucky campsite #7, we quickly unloaded our gear set-up camp, and soothed our aches and pains in the cold flowing river. Not only was that night’s Asian-sesame noodle dinner an unforgettable meal, not just because we would have been happy eating the bark off of trees out of simple exhaustion, but we were also joined by an adult Bald Eagle who secretively watched us eat and then burst out of the trees not 20-30 feet from our group as we were licking our bowls clean. Mesmerized by nature’s magic and full of noodle, we returned to camp to set up our bear hang and relish in the day’s accomplishments by a roaring campfire.

Friday morning came quick, with a mindset of having to make it back to Delaware by day’s end. Our 2-mile paddle to our take out, a public boat ramp nicknamed “The Crusher,” felt like two strokes after everything we had accomplished. We quickly emptied our canoes to be left behind for the outfitter, changed out of river clothes, reconnected with our phones (one teen had over 200 texts waiting to be read!), and loaded the van for the ride home, but not without one last adventure. Second breakfast was had by all at the first fast-food joint we could find in nearby Tupper Lake, which also meant our first real bathroom since Tuesday, and then we headed to The Wild Center, and its new Wild Walk – an elevated trail across the treetops – features 81-acres of outdoors, a 54,000 ft2 museum with live animal exhibits, a natural playground, a native wildflower garden and living pond, and hands-on everything. We spent several hours exploring all the exhibits, picking berries along the trail, and recharging before the long drive home full of Friday night New Jersey traffic (a much slower pace than the river’s current).

We made it back to Ashland late that evening, with our bellies full of “real” food and thoughts of dinners with Bald Eagles, lean-to campfires, and care-free paddling seeming quite distant. Nature’s magic hadn’t left us though, for as we were making the last few turns off the highway, a radio DJ in some far-off sound booth decided to press play on the quintessential road trip song, Queen’s “Bohemian Rapsody,” timing it just right to carry us in to the parking lot as the last head-banging verse came alive. A van that was asleep most of the ride awoke at the first sound of the song (I did crank the radio up to 11), and the whole crew began in unison “Is this the real life? Is this just fantasy? Caught in a landslide, no escape from reality. Open your eyes, look up to the skies and see. I’m just a poor boy, I need no sympathy, because I’m easy come, easy go, a little high, little low. Anyway the wind blows, doesn’t really matter to me, to me.” The Ashland parking lot didn’t have a “DANGER tests and grades / college applications / back to DNS jobs AHEAD” sign as we puddled in, but after a week of being forged in the Adirondack wilderness the song was a fitting reminder that anyway the autumn winds head blew us into calm waters or another portage, it didn’t really matter to us.
