Penn State’s Living Filter

I participated in this event as part of my commitment to Centred Outdoor’s Outdoor Leadership Cohort. I recommend participating in their events throughout the Summer and Fall seasons. You can check out their schedule on their website. Please consider supporting Centred Outdoors and Clearwater Conservancy today.

Last Sunday, I packed a bag and dashed out the door to reach Penn State’s Living Filter in time for the 1:00pm guided tour. I wasn’t sure what to expect… I had gathered from promotional materials that the Living Filter was an experiment, yet also an established wastewater management practice. From the guided walk, I learned the Living Filter was much more than what met my eye.

Dr. Preisendanz from the Department of Agricultural and Biological Engineering met us at the sign-in station to share the history of the Living Filter. For almost four decades, Penn State has used their wastewater effluent as forest and crop irrigation. The hope is that after nourishing the plants and crops, the water will recharge groundwater aquifers. Wastewater is sprayed over the foliage using aboveground pipe systems. This wastewater is some of the cleanest wastewater around- Penn State recently upgraded their wastewater treatment facility to better treat the wastewater from University Park campus and part of State College.

Penn State staff, faculty, and researchers play an active role in maintaining the Living Filter. To ensure proper safety and security of the pipes, staff manually turn on and off the sprayer systems and handle the collection of samples for researchers. Working together, they have managed to eliminate the direct discharge of wastewater into streams and assist in maintaining the base flow of Spring Creek. Plus, this system supports different crops which are used to nourish research animals, eliminating the need to purchase and transport commercial feed.

During our walk, we soaked in the lush foliage around the service roads. Thick bushes of jewelweed lined our walking path. Grain crops emanated a warm and comforting glow over the hills. Climbing up over the grain fields, we passed into fields of tall, strong corn. While the hedgerows were not perfect, they were tidy. However, not all plants love the nutrient-rich water. Some trees, most of species that prefer dryer territory, were fading or even already dead. Penn State technical service staff maintain the safety of the Living Filter by removing any dead trees before, or immediately after a tree goes down.

While the Living Filter is an inspiring facility, what caught me by surprise was the investment of the community members attending the outing. Our small crowd was certainly a mix of ages, experiences, and knowledge. We stopped multiple times during the walk to ask Dr. Preisendanz questions, which she met with enthusiasm. I felt comfortable in this group of (mostly) strangers, and happy to listen to the discussion surrounding wastewater management and sustainable agriculture. I learned that the morning group was larger and had even more questions than us. The 11:00 am group took over an hour, while ours was just under!

On my way home from the outing, I drove past the site of the old Radio Astronomy Building. Now a decommissioned special services building, the area of what used to study celestial objects using radio waves now is the home of the Living Filter’s second half. I didn’t stop to check it out as I was unsure of the permissions one would need to see it for themselves. The initial portion of the Living Filter, on State Game Lands 176, is publicly available. However, be warned that the sprayers are turned on for all other days- even in the middle of winter.

I enjoyed my visit to Penn State’s Living Filter. The “lesson” was fun, the walk was easy, and the attendees were interesting. While this place is checked off my To-Visit List for the Summer, it’s on my To-Visit List for the Winter. Dr. Preisendanz shared the area is a winter wonderland starting in December and worth the trip. For now, when I wash my dishes in the breakroom sink, I know the water will exit the system at the Living Filter!

Nature Journaling Sit-Spots

My break lasted longer than planned. As our wedding approached, time sped up, punctuated by frequent thunderstorms. The periodical cicadas came and went in their screaming glory. Pennsylvania has slipped into the dog days of summer, and Sirius rises high over us in the nighttime sky. The lake calls me, and I resist the urge to swim all day, every day.

When I first moved here in the summer of 2020, I worked from home each day. During my lunch breaks I would dash to the dock and slip into the water. I could take a dip at the boat launch and crawl out on the bank at the other side, undisturbed. I’ll never know if the park rangers let me have fun or chose to ignore my small-town antics.

While visiting earlier this week, the launch was quiet enough for me to sit at the end of the dock to nature journal. The sparkling summer lake was a fun challenge to capture in a pencil drawing. Beneath my feet, bluegill hovered around the dock pilings, their fins glinting gold. One snuck up to my foot to check me out, sucking in water through its nostrils to detect my scent. I drew the scene in my journal, delighted as the fish gathered near me.

Other delights found themselves in my journal. Several bass were jumping out of the water- from predation or delight, I won’t ever know. I captured the blue-fronted dancer that rested on my knee, and a green dragonfly that swept around my face. Tufts of algae floated by me, caught in the wake of a speedboat and my nature journal. After filling the page with pencil drawings, I packed my journal away to lay on the dock and watch the clouds.

Having a sit-spot, a place to sit and journal at many times over a period, is a common practice. Sit-spot recommendations include spaces that are at home, or if not, very close to home. My first sit-spot was on my porch, a safe and secluded spot where I could experiment with my journal in peace. Soon after, I started taking my journal on lunch break walks, and I developed a second sit-spot.

Bald Eagle Launch, where I was earlier this week, is my second and favorite sit-spot. I can sit anywhere on the property to journal… on the dock floating in water, under the pavilion, perched on the trail bench, or draped on the grassy hill. Every angle is beautiful, every corner of the area holds some fascinating bit of nature. Long before I kept a nature journal, I wrote in my diary here- and many, many pages of daily nature observations.

I’m not alone in having multiple sit-spots. One of my nature journal inspirations, Clare Walker Leslie, journals at several places. In her books, she shares pages from her spot at Mount Auburn Cemetery, her country home, and her city home. As she cycles through locations, the seasons pass and she captures snippets of time all over.

I know Bald Eagle Launch will remain as my most favorite sit-spot. Yet, I’m always on the hunt for a new spot- a place for me to visit every so often and witness nature throughout the seasons. The rest of this summer, I plan to attend Centred Outdoors events and journal my way through every outing. You can check out the schedule online and make a plan to join me!
