New water quality technology makes its debut in Buzzards Bay

Each 5 days, Lisa Kingston, a 62-year-old important care nurse, drives to the Onset pier to gather samples within the murky waters of Buzzards Bay.

“That is our oxygen bottle and that is our salinity bottle. We pull this — bloop, bloop, bloop, bloop, bloop —” she says, imitating the sound of water, “and that fills up.”

On the finish of this dock, Kingston performs an hour-and-a-half-long information assortment routine — simply as she has finished 22 occasions a summer season for the previous two years. She and fellow volunteer Susan Scott are right here to take measurements on oxygen, water temperature, salinity, and extra. Scott, a 77-year-old retired arts administrator, rips open a reagent packet and provides it to a glass vial.

“There’s a sure kind of MacGyver-ish high quality to it,” she mentioned. “Whereas there’s a course of and it’s a must to do it in a sure approach, anybody may do it. You don’t need to be a educated scientist.”

Kingston and Scott are amongst dozens of volunteers who participate in one of many longest-running water high quality applications within the area. Their work helps scientists perceive how a lot septic techniques and garden fertilizers are polluting Buzzards Bay with nitrogen. Extra nitrogen may cause poisonous algae blooms and dangerously low oxygen ranges that make it practically unimaginable for marine life to outlive. So, Kingston mentioned, the work is significant to volunteers.

“You need to maintain the issues that convey you pleasure,” she mentioned. “And I couldn’t think about not with the ability to be a part of this bay, or not desirous to be in it.”

For greater than three many years, volunteers have been important to monitoring the well being of the bay. However now the Buzzards Bay Coalition is experimenting with a brand new system, one the place know-how is used to repeatedly take a look at the water. It means fewer information gaps and fewer human error, but it surely additionally means volunteers are a smaller a part of the method.

The brand new tech

“So we’ll pull up a logger and present you what it does,” mentioned Chris Neill, a senior scientist on the Woodwell Local weather Analysis Middle. With him was researcher Kristin Huizenga of the Buzzards Bay Coalition. The 2 organizations are collaborating on this undertaking.

Huizenga crouched on the finish of the pier and hauled up an algae-covered milk crate stuffed with scientific devices.

“They’re principally little cylinders,” she defined, pointing to the so-called information loggers; every is in regards to the measurement and form of a glasses case.

“There’s one which has a copper cap on high — that’s the dissolved oxygen sensor. After which there’s one other one which’s all black, and that’s our conductivity and temperature sensor.”

All Huizenga has to do is join a cable and obtain the info.

“We are able to hook it as much as our pc,” she mentioned. “After which we are able to see that information and the way it modifications all through the day and over weeks.”

Neglect the period of volunteers getting water high quality information each 5 days. These loggers are gathering info each 10 minutes. They’re nonetheless fairly new, however they’ve already begun to indicate that dangerously low oxygen occasions have gone undetected as a lot as 40% of the time.

Now, Neill says, findings like these might be used to create higher protections for the bay. They may, for instance, push coverage that limits main close by developments that depend on septic techniques, or coverage that phases in nitrogen-reducing septic techniques for owners.

“So simply realizing that these bays are impaired, there’s this connection to these sorts of actions,” he mentioned.

The Buzzards Bay Coalition will spend the summer season testing information loggers at 19 of the 200 volunteer stations across the bay.

However the brand new know-how may convey a not-so-welcome change for a group of volunteers who’ve been important to the coalition’s mission since 1992. It’s one thing retired arts administrator Susan Scott is considering.

“I’d prefer to be useful wherever I might be,” she mentioned. “So if they are saying, ‘There’s one thing else you can do in lieu of that,’ that’d be nice. Or in the event that they mentioned, ‘We’ve bought the high-tech sensors and so forth, so none of that is obligatory,’ I’d discover some other place to go and assist indirectly.”

However the human contact shall be obligatory to gather some varieties of information for the foreseeable future. So, whilst researchers rely extra closely on know-how, the work of defending the bay will nonetheless depend upon volunteers.
