Summer is going swimmingly here at Friends of Casco Bay, and we have a lot of good news to share:
Our priority legislative bill to create a state-level Climate Change and Ocean Acidification Council was incorporated nearly word-for-word into the Governor’s comprehensive Climate Change Council bill. An Act to Promote Clean Energy Jobs and to Establish the Maine Climate Council passed with strong bipartisan support. In recognition of her yeoman’s work on this issue, Casco Baykeeper Ivy Frignoca was invited to attend the bill signing by Governor Janet Mills on June 26th.
Our water quality sampling season is well underway, as we continue to add to our long-term dataset at 22 shoreside and deepwater sites around the Bay. You may see Research Associate Mike Doan and Casco Baykeeper Ivy making the rounds by land and by sea every few weeks from April through October.
July 20 marks the third anniversary of the launch of our Continuous Monitoring Station in Yarmouth. Our Monitoring Station is fondly nicknamed the “Cage of Science” because its high-tech sensors are housed inside a transformed lobster trap. The instruments measure temperature, salinity, oxygen, pH, and carbon dioxide.
Together, they collect data once an hour, every hour, year round. At this time of year, Mike has to scrape off a new array of marine hitchhikers whenever he hauls up the Cage of Science to download data.
‘Tis the season to think about what not to put on your lawn! With five workshops behind her, Associate Director Mary Cerullo has scheduled another five BayScaping presentations for August and beyond. She is happy to talk with neighborhood groups about green yards and a blue Bay.
There has been such a demand by community groups to volunteer for coastal cleanups and storm drain stenciling projects that Community Engagement Coordinator Sarah Lyman and summer intern Alexis Burns have been very busy. They already have hosted seven events with 106 participants who collected an estimated 238 lbs. of trash and stenciled 238 storm drains!
Our new pumpout boat, Headmaster, was launched on June 10th to pump raw sewage from the marine toilets of recreational boats. Captain Jim Splude, our congenial pumpout boat coordinator, can go about his business more efficiently now with a new boat that has more than twice the holding capacity of the old one.
Our Water Reporter volunteer project is expanding as we hoped and planned. Nearly 40 enthusiastic volunteers attended our Water Reporter training on June 24. Volunteers continue to sign up to keep watch over specific areas of the Bay.
July 10 was the first anniversary of Friends of Casco Bay’s launch of the Water Reporter app. To date, 162 volunteers in this observing network have made more than 500 posts. We call that a great start!
Thank you to everyone who made our Nabbing Nitrogen day a success!
We had 97 dedicated volunteers come out and 90 Nitrogen samples were collected!
To all of our Nabbing Nitrogen volunteers—THANK YOU for braving the chilly rain to sample with us. We were amazed by your enthusiasm and dedication.
We want to also thank the 55 boaters, kayakers, canoers, and paddleboarders who planned on Nabbing Nitrogen with us—we are sorry that the weather did not cooperate with us. The fog, mist, winds, and early morning rain made it unsafe to ask dozens of boaters and kayakers to cross the busy harbor. It was better to be safe than sorry.
You can see photos from the event on our Facebook Page. Thank you to our photographers Dave Dostie and Sonny McAlpin for capturing the day.

Why are we picking on Nitrogen?
Too much nitrogen can turn Casco Bay from a healthy blue to a slimy green. All living things need nitrogen to grow, but an overdose can trigger excessive growth of nuisance algae, reduce water clarity, and lower oxygen levels. This process also releases carbon dioxide, creating acidic conditions that can make it harder for clams and mussels to build and maintain their shells.
By nabbing nitrogen with us, you will help us map nitrogen levels in the Fore River and Portland Harbor—one of the most heavily populated regions in the state. This may allow us to identify problem areas and explore sources of pollution. This effort will provide the Maine Department of Environmental Protection (DEP) with data needed to ground truth its nitrogen model, used to predict nitrogen sources and distribution in this region. Your effort will help our advocacy efforts to establish a limit on how much nitrogen may be discharged into coastal waters.
Where does nitrogen pollution come from?
Excess nitrogen comes into Casco Bay from three different sources, almost in equal proportion—from sewage, from stormwater runoff, and from air pollution (see pie chart). Water quality sampling by Friends of Casco Bay has shown that nitrogen pollution is most severe in areas that are close to shore, near river mouths, at sewer overflow pipes, and other locations where stormwater runoff reaches the Bay. That is why we have created this event to “Nab Nitrogen.”
Nitrogen is contained in human, pet, and animals wastes, in decaying plants and animals, and is released during the combustion of fossil fuels. Sewage discharges from wastewater treatment plants, combined sewer overflows, and leaky septic systems add nitrogen from human waste. Stormwater runoff from land flushes oil and dirt from paved surfaces, pet wastes, and fertilizers from lawns, farms, parks, golf courses, into the ocean. Nitrogen also descends from tailpipes and smokestacks, chimneys, and power plants.
Why at this date and time?
Sampling on an outgoing tide is the best time to measure the influence of land-based sources of nitrogen pollution to Casco Bay. We hope 130 community members, especially sea kayakers and boaters, will volunteer and sample simultaneously at 10:10 a.m., just before low tide. These samples will help us create a snapshot of nitrogen concentrations in the Fore River and Portland Harbor, allowing us to better understand land-based sources of nitrogen pollution in this region of Casco Bay.
How many sites can I sample?
I can’t sample at 10:10 a.m. on July 10. How can I participate?
Nitrogen Nabbing can be done only at the specified time so that samples are collected simultaneously, to help us create the snapshot. If you want to help out with preparation in the weeks prior to the sampling event, there are other ways for you to be involved. Emailslyman [at] cascobay [dot] org to let us know you are interested.
Why are you sampling only in the Fore River and Portland Harbor?
The Maine DEP is refining a model on nitrogen inputs into our coastal waters and needs more data in the Fore River and Portland Harbor. By nabbing nitrogen, you are helping ground truth this model while helping cities, like Portland and South Portland, identify sources of nitrogen moving into Casco Bay.
While this initial effort on July 10 will take place only in Portland and South Portland, we hope to nab nitrogen in the future, in other communities around Casco Bay.
What ifweather is an issue?
In case of dangerous weather, you will be asked to monitor our website www.cascobay.org for any notifications regarding weather conditions. Please provide us with a cell phone number that we can text to reach you. Weather contingencies include the following:
• If there is a small craft advisory, we will nab only by land and not by sea.
• If heavy weather is predicted or approaching (hurricane, thunderstorms), we will reschedule the effort to July 24 from 6 a.m. to 9:30 a.m. (on that day sampling will take place at 8:24 a.m. due to the difference in tides).
What if I have some other issue that arises on July 10?
Please call our office at (207) 799-8574 in the event that you need any help with any contingencies that may arise.
When will we see the results, the snapshot of nitrogen levels in Portland Harbor on July 10?
The samples will be frozen and sent to a laboratory for analysis. After we receive the results, we will construct a map, plotting the various levels of nitrogen at sites around the harbor. We expect to be able to share the results this fall.
What can I do to prevent nitrogen pollution?
Don’t use fertilizers on your lawn.
Plant or retain bushes and trees to keep water from running off your property and into waterways. Go to cascobay.org/bayscaping for more tips on how to grow a green yard to keep Casco Bay blue.
Conserve energy, both in terms of electrical usage and gasoline consumption decreases the nitrogen oxides that lead to acid rain formation.
Buy local—locally produced goods have not been transported significant distances, reducing gas consumption and refrigeration during transportation, which also decreases nitrogen emissions.
Eat organic foods. Because they are not treated with commercial fertilizers, further decreasing nitrogen pollution.
Maintain your septic system by having an annual inspection of the tank and having regular pump outs by a licensed professional.
Empty your boat’s holding tank at a pumpout facility at your marina or through Friends of Casco Bay’s mobile pumpout service.
Burn less oil, wood, and coal to reduce pollution from smokestacks.
Keep your car tuned up to reduce pollution from tailpipes.
