1) Survey – checked to see if all had done survey – yes.

2) Reviewed emails and responses so far and decided to send follow up questions on some:

a. Basement flood water testing. DEC & DEP, DOH – the agencies all pretty much punted but DOH (Scarlett) sent this: the pages below should direct people affected by floods on some steps they may take following a flood and who to contact.

Weather Emergencies
Flooding Quick Reference Guide

Closed out this issue.
* Note: Eymund said at a prior meeting that if you have repeated flooding, take samples to him and he can have testing done down at the Navy Yard.

b. Real-time canal monitoring/public reporting DEP – Alicia West this may deserve a resolution and a presentation – We will have a presentation from Riverkeeper at the General CAG meeting in September when they have more info from DEP as to what they are planning to do. Joan followed up with Alicia 7/29. The City has asked for leave to appeal to the Court of Appeals so the standard response was received that the agency cannot comment on pending litigation.

c. Bond-Lorraine Sewer – DEP Alicia West – See the relevant section of her July 31 in the addendum. Basically – The DEP’s plan is to re-sewer all of Carroll Gardens/Gowanus, from Court Street to the Canal, and from Douglass Street to 4th Street at Public Place. It will eliminate the old brick Bond-Lorraine sewer, including the section under Public Place, and that work will be DEP work, not developer work. Appears DEP will run the sewage from Smith to the canal northwards to the Pumping Station, while they run the storm water from that area south where it will be dumped into the canal at Public Place. Design planned to go to DDC by year’s end.

d. CSOs – DEP Alicia West, EPA Victoria Sacks – We got an answer from DEP regarding its Long-Term Control Plan. See the addendum for full answer but importantly there is no LTCP for the CSO tank results and re-dredging would only happen if EPA orders it. At that point, DEP and other PRPs would be required to dredge. Unsure what other PRP’s we are talking about. No answer from EPA yet – Tom Mongelli to respond. Joan followed up 8/10/2026. The attendees decided this response deserved follow up beyond Joan just asking for Tom’s response. Mark Yarish prepared some questions that Joan sent to Tom Mongelli on 8/9/2026.

e. NAPL leaks and remediation at the head of the Canal – Joan followed up to obtain Victoria’s answers to our questions (see addendum) that Tom Mongelli read out at the CAG meeting 7/27 (see addendum). It seems a lot of what is going on is based on suspicion of what is going on but is also exploratory if EPA has it wrong. Work is in progress. Victoria’s full response is included in the addendum. A series of follow-up questions was sent to Victoria on 8/9/2026. See addendum for details.

Discussion of the CAG membership survey.

1. Discussed ways to get the StoryMap and other materials out to the community. Outreach help? Put on the website? Aaron says, yes, we can do that. Jason to follow up with Celeste.

2. Joan reported that Clinton and Union Street library scheduled to open in the fall. What would an email to the library say? Library should be very interested in the StoryMap. Aaron will follow up to see if the StoryMap can be shared with BPL. We need to draft an email. Can it also be in book form?

3. Asked Aaron if we still have the original draft StoryMap that was much more geared to kids. It would be nice to have both.

4. Joan shared her PowerPoint of the graffiti materials. Eventually we want a show at Dredgers with real items dredged and the graffiti materials but would be great if we could show the StoryMap, too. Aaron will follow up. If we cannot move all of John Quadrozzi’s items to the location we could use the photos we have of them already. Just need frames.

5. Michael Kilian was unable to attend but did say he would reach out to John Quadrozzi and I gave him the email.

6. Jason suggested posters with QR codes and flyers – can the Trust help? Aaron to check. If we get the flyers it would be nice to frame and have hung in new spaces.

Minuted of the July 31, 2026 Meeting of the Gowanus Canal CAG’s Administration Committee

Attendees: Jerry Armer and Katia Kelly via Zoom.

Katia informed Jerry that at the July 2026 full CAG meeting, the Facilitation Committee presented its work on identifying opportunities to increase representation through additional outreach and new member recruiting.

During the discussion, the entire CAG voted to temporarily remove the CAG’s current membership application form from the website, so that we may work on a replacement application that would better align with our recruitment goals.

The hope is to have the new one by mid September.

There is currently an application in front of the Administration Committee. At the general meeting, our committee asked that this application still be reviewed under current membership criteria.

Jerry and Katia reviewed the membership application from Kayla Moriarty.

It was decided to move the application forward because Kayla is a resident of Gowanus and lives very near the Superfund remediation area.

Jerry and Katia felt that she will contribute new thoughts and fresh eyes to our CAG discussions.

Katia will contact Kayla to let her know that the CAG will not be meeting in August, but that she will be invited to the September or October meeting for an interview.

Gowanus CAG Land Use Committee Letter to NYSDEC and NYSDOH re: PS 372 Vapor Intrusion

The Gowanus CAG Land Use Committee has prepared a letter, following a technical review of agency records and vapor-intrusion research, seeking answers about continued volatile organic compounds (VOCs) detections in the P.S. 372 Annex cellar. The letter asks the responsible agencies to explain the remaining source, complete and verify additional mitigation, clarify whether affected spaces are safe for young children to use, and provide ongoing monitoring and public updates before normal school operations resume in September.

You can find the letter here.

Minutes of the July 7, 2026 Meeting of the Gowanus Canal CAG’s Land Use Committee

Attendees: Steve Marcus – Moderator, Andrea Parker, Erica Eliason, Joe Ann Brown, Hildegaard Link, Jason Schwartzman, Mark Yarish, Lisa Bowstead, Joan Salome-Rodriguez, Linda LaViolette, Peter Reich

Guests: Irene Baker & Aaron Kaufman

The Land Use Committee discussed the following:

1) Gowanus Protection Framework
We thanked Jason and Andrea for all their work on drafting and editing the Gowanus Protection Framework that the entire CAG reviewed and voted on to be sent to EPA, NYSDEC & NYCDEP.

2) Environmental Remediation Dashboard
Jason demonstrated his amazing creation of an interactive Environmental Remediation Dashboard as a tool for the entire Gowanus community to use. You can find a link to Jason’s dashboard here.

3) EPA’s Matrix for Remediation Requirements of Gowanus Canal’s Upland Sites
We discussed who is responsible for the enforcement of EPA’s Matrix. It was determined that it is the responsibility of NYSDEC and individual developers of adjoining sites to adhere to EPA’s Matrix requirements.

4) NYSDEC’s TCE Plume Trackdown Study for the Luquer & Court Street area.
The Committee will be working with the Outreach Committee to determine how best to proceed.

5) NYSDEC’s letters regarding PS 372’s vapor intrusion issues & follow up.
The Land Use Committee discussed copies of letters it recently received about the status of the soil vapor intrusion investigation at PS 372’s Annex on 1st Street, between 3rd & 4th Avenues. The letters are from NYSDEC to the school’s principal, detailing the steps that have been taken to investigate soil vapor intrusion, and then to address it once exceedances were found. The letters indicate that there is evidence that the soil vapor intrusion persists despite remediation solutions, and so the investigation is continuing.

The Committee decided to take the following actions:
– Hildegaard and Mark kindly volunteered to draft a letter to DEC requesting further information on its past and current actions to ensure the health and safety of students and staff.
– To reach out to school personnel for further information on its concerns about the overall situation and actions being taken by NYSDEC and any other groups (DOE, teacher’s union, the PTA).
– In its separate discussions with NYSDEC about soil vapor intrusion across Gowanus, the CAG will engage NYSDEC about special efforts to reach out to property owners in the immediate vicinity of the school so they are aware of their potential heightened risk of soil vapor intrusion. Please see the map that Jason kindly created for more information of neighboring properties here.

6) Former Citizens MGP Works site Fall 2025 Groundwater Monitoring report.
It was brought to the Committee’s attention that the Fall 2025 report had not been posted on the National Grid’s Citizens website. Irene Baker who represents National Grid at our CAG meeting was present at our meeting and we would like to thank her for following up and alerting us that the report dated April 16th, 2026 has just been posted on their website. Here’s a link to the Citizen’s website: https://www.citizensmgpsite.com/index.html.

And you can find the Fall 2025 Groundwater Monitoring report here.

7) NYCDEP’s Waterbody Advisory Dashboard & Riverkeeper v. NYCDEP
Mark shared with the Committee NYCDEP’s website that shows accumulated rainfall and CSO activity in and around NYC and specifically the Gowanus Canal as a useful tool especially after wet weather events.

Here’s a link to the website: https://nycwaterbodyadvisory.azurewebsites.net/

In addition, Joan briefly discussed Riverkeeper’s Appellate Division 2nd Department’s decision (see a copy here), which will be discussed further at the September General CAG meeting.

The next Land Use Committee meeting will take place on Tuesday, August 4th at 6:30 p.m.

Minutes of the Gowanus Canal CAG Outreach Committee’s Meeting of July 13, 2026

Attendees: Jason Schwartzman (Facilitator), Katie Bishop, Lisa Bowstead, George Fiala, Andrea Parker, Joan Salome-Rodriguez

Overview and Timeline for Town Hall on Soil Vapor Intrusion
• Target Date: September, aligned with the timing of the Department of Environmental Conservation’s (DEC) annual soil vapor investigation reports.
• Primary Goals: 1) To raise awareness of Soil Vapor Intrusion and the health impacts among Gowanus property owners and renters; 2) To encourage property owners to opt into DEC’s free testing and mitigation; 3) To provide practical information on the nuts and bolts of what’s involved in the testing and mitigation of a property.
• Target Audience: Property owners, renters, businesses and schools within the specific Gowanus soil vapor investigation area.

Immediate Action Items & Strategy
• The committee will first approach local elected officials—Council Member Shahana Hanif, Assembly Member Jo Anne Simon, and State Senator Andrew Gounardes—to ask them to co-host the event and officially invite the DEC.
• Andrea volunteered to email the officials and their top staff.
• The committee will meet in August to finalize the specifics of the outreach campaign, hopefully with feedback from the elected officials.

Community Outreach & Spreading the Word
The committee emphasized that previous DEC meetings failed to draw a crowd because they were poorly publicized, and brainstormed outreach strategies, including the following ideas:
• George Fiala offered printing services and space in The Red Hook Star-Revue.
• Handing out flyers block-by-block and door-to-door.
• Partnering with neighborhood groups to get the event publicized through their networks.
• Reaching out directly to local PTAs to engage parents whose children attend schools in the area.
• Leveraging the email lists and newsletters of local electeds and Community Board 6.

Minutes of the July 6, 2026 Meeting of the Gowanus Canal CAG’s Archaeology & Historic Preservation Committee

Attendees, CAG Members: Joan Salome-Rodriguez, Moderator. Jason Schwartzman; Joseph Alexiou arrived late but meeting had ended; Michael Kilian was out of town but emailed.  

Guests: Irene Baker, National Grid; Aaron Kaufman, Gowanus Remediation Trust, stuck in transit and could not attend.

You can watch a video recording of the meeting here. Please enter passcode yRz%As.0 for access.

1. Discussed ways to get the Storyboard and other materials out to the community. Outreach help? Yes. Jason will discuss with Aaron Kaufman and Celeste via email to figure out if the Storyboard can go up on the Website and Instagram. The question is technical. Can the programs we have actually accommodate it?

2. Joan reported that Clinton and Union St library scheduled to open in the fall. What would an email to the library say? Library should be very interested in the Storyboard. Joan will visit once its open.

3. Agreed to work with Outreach and reach out to Celeste at Gowanus Dredgers for an event including a projection of the Gowanus Graffiti materials and various dredged objects. Celeste is interested – slideshow of graffiti, objects displayed? Awaiting slideshow from Joseph.

4. Joan emailed John Quadrozzi (see email correspondence here) to set up a visit with Peter to the site and get photos and a sense of what could potentially be moved for display. See below – does anyone have a relationship with him? Maybe Michael could follow up and introduce himself? Michael Kilian was out of town but e-mailed that he and his wife will reach out to John Quadrozzi. Will follow up in August.

5. Eymund not present but had agreed to share a bunch of Gowanus Graffiti subway art from 2011. Joan will do another paddle to capture some of the stuff along the Canal.

6. At the last meeting Peter suggested that a few of the images in our collection of graffiti be printed and framed and ask the nearby buildings where the artwork was to display in their space. See notes in the Gowanus Graffiti collection. How to raise $ for framing? Donations? Joan will search online for cheap frames to see if it can just be done out of pocket.

STILL TO DO
7. New semester so outreach to Brooklyn College Museum Studies Program and to Pratt’s archaeology team is timely now to see if there are any opportunities there. https://www.brooklyn.edu/bc-news/curating-excellence/. If we are going to set up exhibits they may be able to help. bbingham@pratt.edu – What should an email to these programs say? Draft at this meeting.

Jason suggests to pitch with the storyboard to the colleges and the provenance we have for the items as well as the slide show of Gowanus Graffiti and, hopefully, of Gowanus wildlife.

Minutes of the July 6, 2026 Meeting of the Gowanus Canal CAG’s Water Quality & Technical Committee

Attendees, CAG Members: Joan Salome-Rodriguez (Moderator), Erica Eliason, Corinne Jenner, Jason Schwartzman, Susan Yung

Guests: Irene Baker, National Grid; Aaron Kaufman, Gowanus Remediation Trust.

You can view a video recording of the meeting here. Please enter code Hg4&gbW# when prompted for access.

The members edited, reviewed and approved emails (see addenda linked here for text) the committee had previously approved sending to various agencies regarding the following:

– Basement flood water testing. DEC & DEP, DOH
– Real-time canal monitoring/public reporting DEP – Alicia West this may deserve a resolution and a presentation
– Bond-Lorraine Sewer – DEP Alicia West
– CSO’s – DEP Alicia West, EPA Victoria Sacks
– Hydrology – This may deserve a resolution: Current hydraulic conditions, including groundwater elevations and flow direction. This study by DEC was scheduled for completion in late 2024. Per Aaron DEC is working on it. Followed up with Aaron 4/27/2026. See addenda – we know they are not including toxins in the study. Suggestion – overlay the map. – Now that Jason has created a tool, can DEC use it once its survey is done? Though we want answers to the questions above, for now, we asked only ETA for the study and what the purpose of it was for DEC.

Housekeeping:

1) PowerHouse walkway at TB1.
2) Mounding: We will follow on the mounding studies once EPA presents on them again. Issue is forward looking – climate change.
3) Dissolved Oxygen Levels: Any acknowledgement from Fagel, Waldron or Smith to our resolution re: DO levels, Erica? NOT YET
4) OMP: What is EPA’s demand for responsible parties to maintain an operation and maintenance plan (OMP) for the Gowanus Canal Clean-up strategy? Who will ensure that the OMP is done going forward? Will EPA continue to check that the water quality remains good and that the cap is intact? Does EPA have an OMP Plan? Where is it? Will follow with Katia at next meeting. Any answer?

– Has DEP started to measure how much of first flush the new buildings are capturing? We did not cover this yet.
– Did the scientific projections in the LTCP account for the results of climate change? We eventually will ask questions about this.
– Outreach – can the artists stop dumping their paint in the canal by washing brushes, etc… Eymund said at the June meeting that this is an issue in the canal.

Minutes of the June 1, 2026 Meeting of the Gowanus Canal CAG’s Water Quality & Technical Committee

Attendees, CAG Members: Joan Salome-Rodriguez, Moderator. Eymund Diegel, Emily Mitchell, Jason Schwartzman, Mark Yarish, Susan Yung.

Guests: Irene Baker, National Grid. Fabio Perla, Gowanus Remediation Trust.

Agency Questions –

Long discussion on how to get basement flood water tested. Per Eymund, if there is a repetitive flooding condition, people could bottle the water (clean container) and have the Water Quality Testing Committee send the sample to the lab at Brooklyn Army Terminal but mostly what they are testing is enterococcyx, not chemicals. Eymund says it is hard to know what chemicals are from historical industry and what is stuff just lying around the basement. However, they would consider doing the testing if the flooding is consistent like Peter’s building.

Thus – Joan will email the three agencies below to see if test kits could be made available and one of those agencies could do basement flood water testing. DEC, DEP & DOH
– Basement floodwater testing: Can residents/businesses have a practical way to check floodwater for contamination (kits or an agency-supported sampling option)? If kits aren’t recommended, what alternative is feasible?

Further discussion of whether real-time canal monitoring/public reporting is a possibility: Can agencies evaluate deploying monitors along the canal/outfalls (storm-event focused) and publishing results (e.g., open data/dashboard) with public health context? Prepare an email to DEP – Alicia West – ask for it at Bond Street and 2nd Street outflows. (Double check these locations with Eymund). Also reach out to FLOOD NET at NYU.

Additional questions as a follow-up to Alicia West’s answer to some of our questions (see email correspondence in the addenda here):.

Addressing Sewer Backups – When or will the City turn to Gowanus? June 9, 2026 Gowanus Oversight Task Force meeting will cover flooding issues.
– Does the new sewer Alicia West described for the west side of the Canal already have a funded line in the City budget?
– Has DEP started to measure how much of first flush the new buildings are capturing?
– A government agency is supposed to model projections for population increases and climate change. Did the scientific projections in the LTCP account for the results of climate change?
Can we get a presentation on the issues above?.
