Clean Water Wednesdays - 2020

Innovative/Alternative Septic Systems

John Smith, the president of KeanTu, will provide summary information and performance data on KleanTu's two Innovative Alternative (I/A) technologies, the NitROE® Waste-Water Treatment System (WWTS) and the SanTOETM WWTS), for enhanced total nitrogen (TN) reduction, that are now being deployed and demonstrated on both Martha’s Vineyard and Cape Cod. Both the NitROE® and the SanTOETM WWTS’s are demonstrating the ability to consistently produce a highly treated wastewater, including significant TN reduction, in a low cost manner.

George Heufelder, co-Director of the Massachusetts Alternative Septic System Test Center will provide information on some of the innovative/alternative systems being tested.

We’ll be joined by Abigail Archer (Fisheries and Aquaculture Specialist, Woods Hole Sea Grant/Cape Cod Cooperative Extension Marine Program) and Betsy Gladfelter (Conservation Commissioner, Town of Falmouth). Abigail will discuss the life cycle and population status of river herring and the history of fish ladders on Cape Cod. Betsy will talk about the restoration of the Coonamessett River in Falmouth and the restoration’s impact on river herring habitat and fish passage.

Jack Ahern, Professor of Landscape Architecture at the University of Massachusetts Amherst, and this talk is Designing with Nature on Cape Cod and the Islands. His talk will explain how to preserve the special environmental and visual character of the Cape and Islands through an “ecologically-based” approach to landscape design. This approach starts with an understanding of the Cape and Islands’ native plants and plant communities, which are well-adapted to local soils and growing conditions. Ahern will discuss how these plant communities can be designed for landscapes where people live, learn, work, and play. His approach will be illustrated with examples of landscapes on the Cape and Islands that have applied this approach. The talk is a preview of Ahern’s upcoming book “Designing with Nature on Cape Cod and the Islands”.

Clean Water Wednesdays - 2019

For our first Clean Water Wednesday on August 7th at 6:30 pm at Cape Cod Beer, we are excited to have Bryan Horsley from the Association to Preserve Cape Cod (APCC) as our featured speaker.

Bryan is APCC’s Restoration Technician and the Program Manager for the Cape Cod Cyanobacteria Monitoring Program. His presentation will focus on monitoring for harmful cyanobacteria blooms in Cape Cod’s freshwater lakes and ponds. Harmful cyanobacteria blooms are an emerging issue in our local freshwater lakes and ponds, which is concerning because they can release potent cyanotoxins into the environment that pose direct health threats to humans, pets and wildlife. The cause of these blooms seems to be a combination of warming temperatures, altered rainfall patterns, and ever increasing nutrient enrichment of our waters.

Bryan’s talk will cover basic ecology of cyanobacteria, associated environmental and human health threats, APCC's Cape Cod Cyanobacteria Monitoring Program, and he will finish with an overview of actions that can be taken to help alleviate the problem.

Join the experts for a beer! And a Raw Bar!

September 11th, our panel will focus on Oysters and the shell-fishing business on Cape Cod. We’ll be joined by three experts in this field; Liz Lewis from Town of Barnstable (TOWN), John Townes from BARS (RECREATIONAL) and Dave Ryan from Cape Cod Oyster (COMMERCIAL). Each speaker in our panel will be representing a different aspect of shellfishing.

Liz Lewis will be discussing The Town of Barnstable’s Shellfish Propagation Program. Their goal is to supplement the wild populations of quahogs and oysters and take some of the fishing pressure off the wild stocks. Everything that they grow goes out to the public for anyone with a Town of Barnstable Shellfish Permit to harvest. Liz will be touching on the basics of how we grow our shellfish and manage the fishery.

Liz Lewis has been the Shellfish Technician for the Town of Barnstable for over five years and has been working for Natural Resources for over seven. She is a graduate of the University of Vermont with a Bachelor’s Degree in Natural Resources and a concentration in Resource Ecology and is currently working on a Master’s in Public Policy. Her lifetime love of the ocean brought her back to Massachusetts where she worked as a Program Educator at the New England Aquarium for six years. Looking for more time outdoors, she found her true passion- growing quahogs and oysters here on Cape Cod. Liz loves to grow shellfish and help people learn about the resources in their own backyard.

John Townes will be talking about the Triploid Oyster and its importance in rejuvenating the oyster fishery on the east coast from Maine to Louisiana, as well as the Pacific Northwest.

John retired and moved with his wife Leigh to Cotuit in 2017 and almost immediately they became members of BARS. They both quickly discovered a passion for shellfishing on The Cape and have been active in many of BARS’ projects and events including helping the Department of Natural Resources planting and harvesting quahogs, and supporting their Clamming for Kids/Everyone classes. John is the new Vice President of BARS.

Dave Ryan will give us an overview of commercial shellfishing and it’s role on Cape Cod.

BIO: Dave Ryan is Director of Operations for Cape Cod Oyster Company, and a Marine Biologist by training. He discovered and fell in love with the oyster business when he first graduated from college. Working in the oyster hatchery at A.R.C. with early industry innovators like Dick Krause, Sue Talin, and Gene Petrovitz, he realized it was the right business for him. “ It was a way of life, not just a job”. Dave is as enthusiastic about what he does at 55 years old as he was at 20.

Join us as we deep dive into the topic of bogs and their impact on our environment. Alex Hackman will be leading our panel, Alex has worked on some of the largest wetland/bog restoration projects in the state.

Title of Alex’s Talk:

Wetland Restoration on Retired Cranberry Farmland: Context, Science, and Status


After retirement, many cranberry farms require active intervention to rejuvenate historic wetlands and address legacy agricultural impacts. Decades of sand application over native soils, ditching, and use of water controls alter natural hydrology and limit the ability of the land to recover. This talk will describe efforts in Massachusetts to assess, design, implement, and study ecological restoration projects on former cranberry farmland. These issues are important to consider and act upon now, given the current wave of farm retirements, on-going development pressures, water quality concerns, and climate change.


Alex Hackman is a Restoration Ecologist for the Massachusetts Division of Ecological Restoration (DER), and manager of a new state program dedicated to restoring wetlands on retired cranberry farmland. Since 2007, he has managed dam removals, culvert replacements, stream channel and floodplain re-construction, and cranberry bog wetland restoration projects. Alex is a Certified Ecological Restoration Practitioner (CERP) from the Society for Ecological Restoration (SER), sits on the SER-New England Board of Directors, and won the chapter’s 2018 award for excellence in restoration. He is a founding member of Living Observatory ( – an organization that links science, practice, and learning about restored wetlands on retired cranberry farmland. Alex lives in Medford with his sweetheart Keri-Nicole, is passionate about public service and helping Mother Nature, and is an avid but terrible kayak fisherman.

Join us for our next Clean Water Wednesday, November 13th, and we’ll be talking about Sea Level Rise! We’ll be joined by two experts Greg Berman and Mark Borrelli who will talk about why we as Cape Codders should be thinking about the impact of Sea-Level Rise!

Greg Berman:

Local Sea Level Rise: History, Projections, & Impacts

Rising seas have played a huge role in the creation and shaping of the Cape Cod shoreline over many millennia. This session will cover historic shoreline changes due to glacial activity, as well as down-scaled projections of sea level rise for our area. Damage from recent storms will be shown in the context of increasing water levels and visualizations of future impacts to the town of Barnstable will be presented.

Gregory A. Berman, PG, GISP is a coastal processes specialist for Woods Hole Sea Grant (WHSG) and the Cape Cod Cooperative Extension (CCCE) where he provides technical assistance on coastal geology topics: shoreline change, erosion control alternatives, potential effects of various human activities on coastal landforms, coastal flood plains, coastal hazards, hazard mitigation analyses, and dune restoration techniques.

Mark Borrelli:

The Science behind Sea Level Rise: Natural Variability and Human-Induced Change

A brief, science-based introduction about what we know regarding sea level rise. Placing the natural variability of climate change and sea level rise in context within geological and human time scales. This presentation will cover seminal discoveries, recent projections and ongoing work.

Dr. Mark Borrelli is a Coastal Geologist. He is the Director of the Coastal Processes and Ecosystems Laboratory, or CAPE Lab, a joint research effort between the Center for Coastal Studies in Provincetown and the University of Massachusetts at Boston. His research interests include coastal sedimentary processes, in general, and understanding how storms, sea level rise and human impacts affect the coast, in particular.
