Synopsis of October’s Meeting

October’s community meeting was super exciting, with high levels of engagement and participation from community members. We hope for this high level of energy to continue into our next meetings! We started off the meeting with guest speaker Robyn Smyth, Professor at Bard College, who discussed about harmful algae blooms, also known as HABs. HABs are a global issue and they produce toxins that are harmful to aquatic and human life. However, Robyn made a clear distinction that not all algae are harmful, and they are significant to the ecosystem. They are the base of the food chain and produces oxygen! HABs are driven by excess nutrients. For example, when we put excess fertilizers, it accumulates and runs off into the lake/ river, which encourages the overgrowth of algae (an algal bloom). When they die, they deplete the oxygen levels in the water and sink to the bottom of the water. This process is known as eutrophication. HABs are also driven by climate change! In particular, in the Northeast, we are experiencing less rainstorms; however, they are much more intense. This results in erosion, which also contributes to excess nutrients into bodies of water. Some potential solutions are applying algaecides or using forms of artificial mixing. If you suspect a harmful algal bloom, do not touch it! Please take pictures of it and send them to the NYS Department of Environmental Conservation. To read more about algae blooms click here for Robyn’s presentation.

Next, we had Hunter Matis, an undergraduate senior at Bard College, to demonstrate the Flowcam. The Flowcam is an incredible machine that functions like a microscope. You can pour water samples into the Flowcam, and it is able to capture photos of the organisms that are in the water. Isn’t that super cool?! To check out some of the organisms, click here for Hunter’s presentation.

Afterwards, we had a great community conversation discussing about concerning farm practices. Eli Dueker made an awe-inspiring point that it is important for people who care about our water (and the environment) and farmers to come together as a community to try to tackle environmental issues. Karen McDonald also added that it is vital to support farmers but also recognize the bad farming practices and try to fix it. Another community member that beautifully wrapped up this conversation mentioned, “The question we should be proposing is ‘How can we help? And how can we come together?’”

Summer Days

Coming back to sample in the Saw Kill during the summer was amazing. It was a great experience to be able to enjoy and appreciate nature- trees and plants are fully bloomed. Every angle of the Saw Kill was beautiful and the sun’s warmth contributed to the perfect sampling morning. Here are some photos of the Saw Kill so you can enjoy its beauty too!

It was also great sampling with new student volunteers from the Bard Summer Research Institute (BSRI). It was exciting to learn about the Saw Kill from different perspectives.  Using a dipper, we collected water and placed it into a bottle. Using the YSI, a water quality monitoring equipment, we tested the conductivity, temperature, and level of dissolved oxygen. We also took observation notes of the Saw Kill. Here are some awesome action photos!

The Big May Meeting: The State of the Saw Kill Forum!

Thank you to everyone who presented and attended the forum! It was great seeing so many people and learning so much more about the Saw Kill.

May’s meeting was a huge presentation about the overall condition of the Saw Kill Watershed. Carolyn Klocker, a member of the SKWC Leadership Team, began the meeting by explaining the mission of the SKWC, which is to protect the Saw Kill Watershed through science, education and advocacy. Carolyn then introduced Karen Schneller-McDonald, the chair of the Leadership Team. Karen explained more in depth about the mission of the SKWC. Our science programs that we facilitate comprises of our monthly water monitoring, the eel monitoring, and the salamander migration. We educate communities and people by holding monthly meetings and student research. Moreover, we advocate for the watershed holding community discussions and encouraging communities to enjoy the Saw Kill.

Next, Eli Dueker, member of the SKWC Leadership Team, described the value of the Saw Kill; it is extremely beautiful, and it provides recreational uses for many people. In addition, the watershed is a drinking water supply for the Bard community. Eli then focused on the interpretation of sewage indicators on the Saw Kill. He revealed that there were lots of contamination from 1967 to 1982, which was illustrated through the analysis of the fecal indicating bacteria. Fortunately, today, most sites have low levels of contamination, except for Brenner Road. This means that we should do more sampling near that area. We also seem to have an increasing amount of nitrate which could be related to an increase of lawn fertilizers. Stuart Findlay took over and continued presenting on the overall quality of the Saw Kill. Stuart disclosed that the Saw Kill has moderate nutrient concentration which is normal because the Hudson Valley has some areas of development near the watersheds. Moreover, issues of algae aren’t severe. Ultimately, the Saw Kill is well studied, and we should continue with the work.

Afterward, Katherine Meierdiercks, a professor at Siena College, presented about the impacts of road salt. It was revealed that the usage of salt in the U.S. had increased, and the concentration of salt in surface water typically surpasses EPA standards. Essentially, salt concentrations increase as time and urbanization increases. Fortunately, salt concentrations in the Saw Kill are below EPA and NYSDEC standards. Next, Jen Cavanaugh, member of the Red Hook CAC, assessed the effectiveness of the Saw Kill Watershed’s flood mitigation. Jen recommended infrastructure that needed to be fixed. Such recommendations included the removal of the Annandale dam, replacement of the 9G bridge, and realignment of the Echo Valley Bridge.

Lastly, Dan Shapley, director of Riverkeeper, suggested proactive steps that communities can take to protect their drinking supply. Such steps comprised of the usage of the Riverkeeper score and partnering with NGOs. Dan also disclosed the issue of water contamination in New York State, such as the Newburgh crises. We finally wrapped up the meeting by having an open discussion with community members on potential steps to help the Saw Kill, possible solutions, and concerns and issues. Some potential steps that were concluded were naming public access point and conducting source water evaluation. Some possible solutions listed were connecting people to the Saw Kill and conducting further treatment by using the wastewater treatment plant. Ultimately, some concerns and issues that were voiced is the potential overloading of septic tanks in Red Hook and over usage of lawn fertilizers.

Summary of April’s Community Meeting!

April’s Community Meeting began with an update on the Bard Water Lab, given by Clara Woolner. Clara plotted graphs using data collection from December to April (except for January). In summary, she explained that her data shows low counts of enterococcus bacteria and that conductivity levels relatively stayed the same during winter months. However, there is an expectation that conductivity levels will rise during the summer. She also mentioned that Site 6 along the Saw Kill on Benner Road, has higher levels of conductivity and bacteria than any other sites. Afterward, Laurie Husted disclosed the issues on dams. For instance, they are a disturbance to aquatic life and are expensive to maintain and remove. Currently, there are two dams on Bard College’s campus and Bard is looking for funding to study the dams. Later, Sheila Buff provided an update on Amtrak’s agenda. They want to install fences around the train tracks to ensure safety, but this poses a great issue for wildlife and people who want to enjoy the river.

Dr. Emma Rosi, an ecologist at the Cary Institute, soon presented on the effects of pharmaceutical drugs and personal care products in rivers. She begins by explaining the rivers’ sources of contamination: the toilets. When people take drugs, it usually isn’t metabolized by our bodies and the drugs come out through our urine and feces, which is flushed down the toilet. People also flush expired or non-expired drugs down the toilet. Drugs that are flushed down the toilets becomes very problematic because the wastewater treatment plant isn’t designed to properly filter out the drugs, so the river becomes contaminated with drugs. The river also becomes contaminated through the landfill. We place 50% of our feces, and solids (composed of drugs) onto land. However, when the landfills leak, the feces are taken to the wastewater treatment plant. This is problematic because (as mentioned previously) the wastewater treatment plant doesn’t filter the drugs. Another practice that pollutes the water is by simply applying lotion, or sunscreen. When we shower, the chemicals are washed up and sent to the wastewater treatment plant. Again, the plant doesn’t filter out the chemicals, so it ends up in the river. Moreover, we put a lot of drugs such as antibiotics in livestock. So, when the livestock excretes waste, drugs are excreted as well. We then apply the waste into landfills, and the cycle of polluting rivers continue once they move the waste to the treatment plant.

Dr. Rosi further explains her work with the Hudson River. Her focus is examining the impacts of drugs on rivers. She researched the effects of algae on drugs that are prevalent in the Hudson because algae are very significant. They are the base of the food chain and they are often exposed to drugs since they bloom in streams. She found that drugs such as Triclosan, and antidepressants, stunt the growth rate of algae. (Triclosan are antibacterial agents found in care products such as toothpaste. It was banned in soap production in 2016). She had also done lab work with putting bacteria on drugs, such as Triclosan, and analyzed how quickly they will grow resistance to drugs. She found that the bacteria have quickly grown resistance and bacterial communities had fundamentally changed. She also put bugs on drugs, such as Cimetidine, which helps with stomach acid. She found that the bugs emerge into adulthood much faster.

Dr. Rosi reveals steps we can take to reduce drugs in our rivers. She explains that we must not flush our drugs down the toilet. Instead, we can take expired or unwanted drugs to pharmacies and they will incinerate them properly. Additionally, we can encourage our local politicians to upgrade and maintain our wastewater treatment plant. Lastly, we can encourage and support research on rivers.
