Episode 42: Overflow

From Lake Champlain to the Connecticut River, overtaxed sewage systems are being pushed to filter out more pollutants. This week, we look into what it takes to clean up our water systems. We also revisit Boston’s aborted Olympic bid in search of lessons about urban planning and civic engagement. We follow the journey of an aluminum can, and meet a DIY Youtube star from the woods of Maine.

Influent and Effluent

By the end of the year, the Environmental Protection Agency is expected to announce new limits on the amount of nitrogen that wastewater treatment plants in Massachusetts, Vermont and New Hampshire can release into New England’s largest river, the Connecticut.

These new rules could mean a small tweak of the system, or a costly plant retrofit. No one knows for sure until the limits are announced.

Nitrogen is a nutrient in soil, but when it reaches salt water it becomes a pollutant. And it’s nitrogen that’s blamed for fish die-offs in Long Island Sound, where the Connecticut river ends. New England Public Radio’s Jill Kaufman has our story.

There’s another nutrient that’s plaguing water quality in New England: phosphorous. It’s linked to toxic blue-green algae blooms in Lake Champlain.

But that’s just one of the problems the podcast Brave Little State went to investigate for their latest episode. This people-powered program from Vermont Public Radio asks for listener questions. This month, listener Mike Brown asked, “How are we going to address the aging sewage systems in Vermont?”

Brown was concerned about sewage overflows that were happening more frequently with big storms and flooding. As it turns out, the problem is linked to climate change and an antique sewer system that in some spots predates the automobile.

Our guest is Vermont Public Radio digital reporter Taylor Dobbs, who co-reported the episode with host Angela Evancie and question-asker Mike Brown.

Lessons From the Boston Olympics That Wasn’t

Paris and Los Angeles are in the running to host the 2024 Summer Olympics. Before the U.S. Olympic Committee set its sights on L.A., it chose Boston.

But the Boston 2024 project was beset by problems, including lack of transparency about costs, and a snow storm that brought the subway system to a grinding halt. (The Boston Globe has a helpful timeline of the Olympic bid.)

In July, 2015, Mayor Marty Walsh announced he would not sign a contract that would promise taxpayer funding for Olympic costs overruns, and the Olympic bid came to an end.

Our next guests are some of Boston 2024’s most outspoken skeptics. Chris Dempsey is a co-founder of the movement No Boston Olympics, previously served as assistant transportation secretary for Massachusetts, and is now the director of the nonprofit Transportation for Massachusetts. Andrew Zimbalist teaches economics at Smith College and studies public financing of sports events.

Demspey and Zimbalist are co-authors of the new book, No Boston Olympics: How and Why Smart Cities Are Passing on the Torch.

While the majority of public opinion in Boston had turned against hosting the games by the time the city dropped the bid, not everyone was happy to see their hometown pass on the Olympic experience. For another perspective, we speak with Boston Globe columnist Shirley Leung, who covered the Olympic debate closely.

Break It Down, Build It Up

After aluminum is melted down (above) chemists inject additives to ensure the alloy is correct for can “body stock.” The material is then cast into giant slabs, which weigh thousands of pounds and are very thick. Those slabs are then milled down to a very thin body, which is cooled and coiled before it gets shipped to can makers. Photo courtesy of Constellium – Muscle Shoals, AL

Except for Rhode Island and New Hampshire, all New England states have bottle bills. Those are recycling programs built around a system of deposits and refunds, aimed at reducing litter and protecting the environment. But when it comes to old aluminum, it’s not just environmentalists who want to see more recycling; there’s a real business case to be made for it, too. WNPR’s Patrick Skahill reports.

There’s a thriving scene on YouTube where woodworkers, metalworkers and other “makers” provide a step-by-step guide to their process.

In Waterford, Maine a maker named Gardner Waldeier — who calls himself “Bus Huxley” — has been entertaining viewers with equal portions of Yankee ingenuity and video wizardry. Jon Kalish reports.
