This group isn’t quite like the rest.

Sure, +POOL has conducted intensive water quality monitoring for the past two summer seasons at four sites along the Brooklyn Waterfront.

And yes, they test for a spectrum of things, including enterococci, pH, and turbidity.

But it’s why they’re collecting the data that’s so unique: +POOL spent the last two years and biked thousands of miles collecting samples along the Brooklyn Waterfront to determine whether it was feasible to build a water-filtering, floating pool in the heart of New York’s watershed.

(Yes, you read that right.)

Revelations strike where and when they want. This particular one occurred in Northern California, far away from the windswept beaches, far from the mighty redwoods, and without a sun-drenched vineyard in sight.

It was, in fact, while slogging hip high through a manure-settling pond in Davis, California that Travis Pritchard decided a change in career was his next step forward. This realization happened to hit him while he was sweating it out taking agricultural water quality samples.

“It was miserable, the guy was a dirty farmer, there were dead cows everywhere, it was not a good time.”

So Pritchard moved south to his hometown of San Diego, where he’s now Interim Executive Director for San Diego Coastkeeper.

Rio 2016. When I look ahead to the upcoming summer Olympic Games, the first thing that comes to mind is the abysmal water quality, and how athletes are expected to swim, sail, and compete in water that could severely endanger their health.

Recent news stories about Rio’s water quality, which shows widespread elevated levels of viruses and bacteria from along the coastline to far offshore, have got much of the world thinking about water quality – not only in Rio, but in their own watershed.

It’s spurred a lot of Swim Guide users to ask: what do they really test for at my favourite watershed?

December 2, 2015 – Toronto, Ontario – Great Lakes and St. Lawrence River beach water quality met government standards 76.5% of the time in 2015, says a new report from Swim Guide ( This is an improvement over 2014, when water quality met standards 72.5% of the summer.

The results come from Swim Guide, the web’s most comprehensive beach water quality service. Swim Guide compared monitoring results for 1,496 beaches around the Great Lakes and St. Lawrence River and calculated the number of days beaches in each watershed passed water quality tests, failed water quality tests, or had no data. The findings published in the second annual Great Lakes and St. Lawrence River Beach Report.
