A group of Fairfax Master Naturalists had a unique opportunity to visit the Noman M. Cole, Jr., Pollution Control Plant, located on Route 1 in southern Fairfax County recently. The visit, organized by chapter president Marilyn Parks, was actually a continuing education “field trip” incident to the state-wide “on-line” annual meeting of Virginia Master Naturalists Chapters.
The Cole facility, located on 400 acres, serves about 40 percent of Fairfax County and is among a handful of water or sewage treatment plants in the United States operating at “state of the art” efficiency. With advanced wastewater treatment systems, the facility is able to remove or “digest” water pollutants, nutrients and contaminants at an exceptionally high level, earning recognition as being in the top tier of the 16,000 publicly owned treatment facilities in the United States, an important achievement for Fairfax County and our local rivers and the Chesapeake Bay. About 75% of sanitary wastewater is treated by similar facilities. The remaining 25 % of waste winds up in private septic tanks.
The facility, which celebrated its 50 year anniversary in 2020, uses a four-stage process to treat south Fairfax County’s wastewater: primary, secondary, advanced treatment and final treatment. After the secondary phase, the effluent moves to three five-million gallon holding ponds. Wildlife thrives in these ponds and 89% of treatment facilities in our country stop their treatment here. The Cole facility, however, goes two stages beyond, which includes using Moving Bed Biologic Reactors (MBBR). This microbiologic process uses tiny, pasta-shaped plastic pieces on which to grow algae to feed “good “microbes that convert nitrates to nitrogen gas. (Nitrogen is the primary gas in our atmosphere.) By the time the effluent is released to Pohick Creek, it is cleaner than the water in the creek.
We were privileged that Cole’s superintendent Mike McGrath took time to personally escort our group on much of the tour, with operations manager Joshua and Melissa showing us the entire physical set up from the bar screen to the water sampling laboratory.
Sewage and sewage treatment is often a subject many choose not to think about: what is out of sight is out of mind. But the men and women of Fairfax County who work daily to run this amazing operation, from the 3,000 miles of collection sewers to the solid waste that is removed from the bar screen – including false plastic fingernails – this is a highly sophisticated, automated operation, that is a real success story that Fairfax residents can be proud of.

Join Kristina Motley, Senior Environmental Specialist, to examine why the Poplar Island project is such a successful model of reuse. This environmental restoration project located in the Chesapeake Bay in Talbot County, Maryland, relies on dredged material collected from the approach channels to the Baltimore Harbor to restore lost remote island habitat within the Chesapeake Bay. This results in restoration of almost 400 acres of wetland habitat where more than 400 different species of wildlife have been documented and more than 30 different birds have been confirmed as nesting. Join Audubon Naturalist Society to learn about this unique story of continuing habitat victories.

As Northern Virginia continues to celebrate trees to mark the start of the five year regional native tree campaign, autumn colors move to center stage. We may not get New England’s sudden (and brief) burst of color from the dominance of sugar maples, but our region makes up for it with the more gradual unfolding of a warm and lingering fall.
Most deciduous trees are best planted in the autumn, which conveniently coincides with the best time to choose a tree for its fall foliage. Trees are like people: within one species, there is plenty of variability, so if fall color is a high priority for you, this is the time to go shopping.
If your attention is drawn to a particular tree on a forested slope in Virginia, chances are you have spotted a Black Gum tree, whose red leaves positively glow in the sun. Other native trees with markedly red foliage include the Red Maples and the Scarlet and Shumard oaks. All these trees are eminently suitable for planting in a yard. Hickory trees have bright yellow foliage and tend to have planted themselves, as they are harder to find in nurseries because their deep tap roots makes it hard to dig them up. The muted red leaves of the Flowering Dogwood, Virginia’s state tree, provide a background for scarlet berries that are an important food source for migrating birds. This brings up two related subjects. The first is that it is important to choose native trees, as it is only plants that evolved within our local ecosystem that support that ecosystem. The second is that fall color is not just about foliage. The berries of many native plants, especially shrubs, ripen in fall and make a bright display that attracts birds to your yard. Many of those shrubs, such as blueberries, chokeberries, sumacs and native viburnums, also have brilliant fall foliage in their own right. Fall is also the time for the many species of the aptly named goldenrod and for the purples, blues, pinks, whites and even yellows of asters. Goldenrods and asters are the host plants for more species of caterpillars than any other perennials. But it is trees that support the most wildlife of all. If you only have the time and energy to plant one plant, let it be a native tree.
One of the fun things about our drawn-out autumn is watching the colors evolve over time. Certain patterns emerge. Sycamores start to fade well before summer’s end, with Dogwoods starting to turn rust red soon afterwards and Sassafras either red or gold. The brighter reds and yellows of canopy trees follow, with oaks being late to turn. Once those are shed, what is left is the light brown leaves of oaks and beeches that hold onto their leaves well into winter. The trees do not march in lock step, though, and there is plenty of variation from year to year, tree to tree, and even from branch to branch on the same tree. The Plant NOVA Trees website includes photos as well as a practical guide to choosing and planting native trees.
You might be thinking that when choosing a native tree, it might as well be one with bright red foliage. But consider that it is not a sea of red that makes autumn so beautiful but the quilt of contrasting red, gold, green and brown provided by the diversity of our woodland species. There are over fifty native species of trees to choose between in Northern Virginia, each of which plays its own important role in the beauty and the ecosystem of our region. Not only would it look odd to see only red trees, planting too many of one species puts the community at risk if disease strikes. Biodiversity is the key to resilience in a changing world.

As we celebrate Birdability Week, October 18 – October 24, 2021, we would like to highlight Steve Tzikas, an energetic volunteer who has been mapping trails in Northern Virginia for their “Birdability.”
“The Birdability Map is a crowdsourced map which describes the accessibility features of birding locations all over the world. This allows people with accessibility challenges to find out in advance if a birding location is one they would like to visit.”
Read Steve’s account of his mapping experience:
In early 2021 I inquired if the Audubon Society of Northern Virginia needed any volunteers for a citizen science field project that involved exercise. As I got older I needed more exercise opportunities, but as a scientist and engineer, I wanted it to involve science to keep my interest. The response I received informed me about Birdability, which was founded in 2016 by Virginia Rose. As the Birdability website notes,
“Birdability works to ensure the birding community and the outdoors are welcoming, inclusive, safe and accessible for everybody.” They “focus on people with mobility challenges, blindness or low vision, chronic illness, intellectual or developmental disabilities, mental illness, and those who are neurodivergent, deaf or hard of hearing or who have other health concerns.”
A lot of information can already be found on the Internet about Birdability, including that found on its own website. Rather than repeat much which has already been noted by others, this article focuses on how a government regulation can become common knowledge to the public.
Accessibility is an important part of trail development, because it is key to ensuring that trails are available to all groups such as the elderly and people with disabilities. The first accessibility laws were enacted in 1968 under the Architectural Barriers Act (ABA) of 1968. The Americans with Disabilities Act (ADA) of 1990 prohibited discrimination based on disability.
After some thought the proposal to volunteer and evaluate trails for Birdability became an interesting prospect, even if not citizen science. Birdability still offered exercise by walking trails, but it also intrigued me. One of my many duties as an engineer over the years was the creation and review of facility design standards and agency policies as they related to specific requirements for the environment, safety, health, and security. These were technical requirements that few people, except professionals, ever see. Such regulations keep the public safe, even if they are not aware of their surroundings and the issues that impact them. Sometimes, during reviews, a rather broad-based standard could include many other requirements not necessarily for my attention, but for other professionals in collaborating offices. As such, I would see information pertaining to ADA requirements.
So, when I reviewed the Birdability template used in trail reviews, I thought about how this organization took a complicated regulation and converted it to an app for the public to use, educating them in the process. Moreover, this caught my interest, because as an engineer I also develop models that track government operations based on transactional data and the resource requirements that are part of those operations. Developing models based on big data is another item only professionals will do. But, Birdability developed a public app based on “dry” government requirements and made it appealing, useful, and educational.
The Birdability survey template covers the basic ADA requirements so people with accessibility challenges can access a reviewed trail quickly and get outside to experience the natural surroundings. When submitting a survey, reviewers are asked to comment on ADA aspects including parking, ramps, restrooms, and other accessible features as well as trail accessibility criteria such as surface(s), slope(s), shade, benches, gates, railings, steps, and viewing blinds.
The largest section is for any additional information. This connects the trail to the types of birds seen, seasonal conditions, width of trails, overall difficulty, wildlife activity, and so on. This is followed by a section for rating the location’s overall accessibility, and there is the ability to add photographs.
I forwarded suggestions for improvements, whether for future upgrades of the website itself, or to fellow reviewers on best practices for entering a review. For example; slope criteria are noted, but it’s not always an easy task to measure, especially if a trail has a lot of vertical variability. Reviewers can’t be expected to conduct an engineer’s transit measurement on every trail slope encountered. At first I attempted to measure the slope with the greatest incline. I used a simple astrolabe I owned to get a quick estimate for the degrees of inclination. However, it was even easier to take a photograph and post it so a reader could decide whether such inclines posed a challenge to their body strength or wheelchair. The photograph section of the survey template acted as a useful place to add information that words alone could not describe accurately. I also noted other ideas by including comments, such as whether a trail is accessible through public transportation.
While most people might associate ADA with people using wheel chairs, the ADA also covers conditions due to deafness, blindness, diabetes, cancer, epilepsy, intellectual disabilities, missing limbs, autism, and other medical conditions.
The accessibility guidelines apply to those trails that are designed and constructed for pedestrian use. These guidelines are not applicable to trails primarily designed and constructed for recreational use by equestrians, mountain bicyclists, snowmobile users, or off-highway vehicle users. Regulations also recognize the existence of constraints and limitations in the outdoor environment and allow for certain other exceptions.
I do many of my reviews in my town of Reston, Virginia. Reston was founded in 1964 as a planned community. Today it has 60,000 residents, over 55 miles of walking paths, about 250 acres of woodlands and open space, 4 lakes, and a tree canopy covering about half of its total area. There is a high degree of accessibility, and there are many birds along the paths and lakes. Birdability offers the chance to get to know your community and what it has to offer. The Birdability map notes the locations where people have submitted reviews. It is constantly growing with submissions.
If you are seeking a good experience with exercise and learning, Birdability mapping may be the one for you. Visit the website and view the Birdability map, where you can read what others wrote, as well as submit your own trail review. Whether it is a simple trail review, or a more thoughtful one that attempts to identify the variety of birds and their habits through the seasons, it’s worth a try.
