Cape Cod needs to clean up its water. The solutions could cost billions – WBUR Boston | Scientific American
Excerpt:
Pat Uhlman lives across the street from Shubael Pond in Barnstable. The round pond is ringed by trees and — most days — crystal clear. “It’s so beautiful,” she said. “I get up in the morning, I open my drapes, and if the sun is already up, the pond is glistening.” But a couple of years ago, the glistening pond turned a milky green. It was a cyanobacteria bloom, known more commonly as “toxic algae.” Toxic algal blooms can make people sick if they ingest the water and are especially dangerous for dogs and small children.
Concerned, Uhlman paddled her kayak into the pond to see how far the algae had spread.
“I kayaked around and I was leaving a trail — you could see where the kayak had cut through the slime,” she said. “You feel almost scared, like, ‘What is going on?’ And that it’s never going to clear up and that the pond is dying.”
Uhlman’s pond did clear up that fall, but algal blooms are an ongoing problem on the Cape. Even the more common, nontoxic growths are destructive, creating low-oxygen dead zones that kill fish and native plants. Now, 90% of Cape Cod’s coastal bays and more than a third of its ponds have “unacceptable” water quality, according to the nonprofit Association to Preserve Cape Cod’s annual State of the Waters report.
“We’ve seen a significant deterioration of our bays to the point where they’re designated as impaired, where we don’t have shellfish, we don’t have finfish,” said Barnstable town manager Mark Ells.
The pollution comes primarily from septic systems, which leach nitrogen and phosphorus — basically fertilizer — in the Cape’s groundwater. The state has tough new regulations that are forcing communities on the Cape to clean up the water. And towns are now grappling with the cleanup’s enormous price tag: in Barnstable alone, cleanup will cost more than a billion dollars.
It’s a critical moment for Cape Cod. The Cape has more than 550 miles of coastline, at least 890 freshwater ponds and 53 small saltwater bays bordering the ocean. That water is the Cape’s raison d’être: residents and visitors use it for swimming, boating and fishing, and it forms the backbone of the region’s $1.4 billion tourism industry. Now Cape Cod communities are scrambling for solutions before their ecosystems, economies and property values collapse.
“Most of our own personal financial wellbeing is intimately tied to the Cape continuing to be an attractive place to live. And so, as individuals we’re all at an enormous risk,” said Andrew Gottlieb, executive director of the Association to Preserve Cape Cod.
“People like Cape Cod and want to come to Cape Cod, and to a certain extent, they’re loving it to death…”

Cape Cod Has a Big Problem Simmering Just Below Its Surface
“There’s going to be bad smells. There’s going to be fish kills. There’s going to be a lot of algae getting entangled in your boat, in your propeller, in everything. And it’s not a nice view, you know…. So in a way, we’re decreasing the value of the land, which is precisely the same value that brought people here to enjoy an enjoyable summer.”
The “yellow tide” under the Cape is rising. So…what is it?

Popular Maui beaches remain open despite no official word they’re safe – SFGATE
Nearly six months after the Lahaina wildfire on Maui, questions remain about how ongoing contamination from the burn zone may be affecting the shoreline of West Maui — even as locals, and an increasing number of tourists, continue to swim and surf at beaches…

We Traced the Forever Chemicals Getting Into Ocean Ecosystems – the Conversation
PFAS, the “forever chemicals” that have been raising health concerns across the country, are not just a problem in drinking water. As these chemicals leach out of failing septic systems and landfills and wash off airport runways and farm fields, they can end up in streams that ultimately discharge into ocean ecosystems where fish, dolphins, manatees, sharks and other marine species live…
Oil spill tops 1 million gallons, threatens Gulf of Mexico wildlife – the Washington Post
Skimming vessels are working to contain and recover oil from a spill in the Gulf of Mexico off the Louisiana coast, which the U.S. Coast Guard on Tuesday estimated to be at least 1.1 million gallons. The spill was discovered Thursday near a 67-mile pipeline operated by the Main Pass Oil Gathering Co., owned by Houston-based Third Coast Infrastructure, and the Coast Guard said it was still reviewing whether that pipeline was the source of the contamination…
Groundwater a significant source of pollution on Great Barrier Reef, study shows – the Guardian
Scientists say they have discovered large flows of pollution are reaching the Great Barrier Reef after soaking into underground water, a finding that could have implications for policymakers focused on cutting pollution from river catchments. The new research claims almost a third of dissolved inorganic nitrogen and two-thirds of dissolved inorganic phosphorus in the reef’s waters are coming from underground sources – an amount previously undocumented…
Road Hazard: Evidence Mounts on Toxic Pollution from Tires – Yale Environment 360
Researchers are only beginning to uncover the toxic cocktail of chemicals, microplastics, and heavy metals hidden in car and truck tires. But experts say these tire emissions are a significant source of air and water pollution and may be affecting humans as well as wildlife…
The race to defuse an oil ‘time bomb’ disaster threatening the Red Sea – Grist Magazine
Ten days ago, the crew of a ship called the Nautica lifted anchor in Djibouti and motored north in the Red Sea. Two tugboats met the vessel about five and a half miles off the coast of Yemen, then guided it into place alongside the FSO Safer, a crumbling, abandoned oil tanker thought to hold 1 million barrels of crude.
Thus began an operation that’s the ecological equivalent of placing the pin back into a hand grenade…
Is Fukushima wastewater release safe? What the science says – Nature
Despite concerns from several nations and international groups, Japan is pressing ahead with plans to release water contaminated by the 2011 meltdown of the Fukushima Daiichi nuclear power plant into the Pacific Ocean. Starting sometime this year and continuing for the next 30 years, Japan will slowly release treated water stored in tanks at the site into the ocean through a pipeline extending one kilometre from the coast. But just how safe is the water to the marine environment and humans across the Pacific region?
The Bay Area faces an imminent threat from sea level rise — but it’s different from what you think – San Francisco Chronicle
Dangerous chemicals hiding in the ground around the Bay Area are due to be released by groundwater as it’s pushed closer to the surface with sea level rise, a new study has found. In many cases, it can happen without warning as cancer-causing volatile compounds escape into schools and homes, experts say…
“Groundwater rise and sea level rise are gradual processes that are accelerating,” said Kristina Hill, associate professor at UC Berkeley’s College of Environmental Design, lead author of the study. “It’s a problem tomorrow, and it’s a problem today…”
