These Brooklyn musicians are playing to deaf ears.

Tenants who use a band practice space close to Brooklyn’s contaminated Gowanus Canal have decided to take action. They are pooling together their resources to pay for a private company to examine the building for dangerous vapors that could cause cancer. This decision came after the landlord rejected allowing state inspectors to enter the premises.

This rehearsal space has been frequented by well-known groups such as TV On the Radio, Coheed and Cambria, and The Blue Man Group. It is situated just a few blocks away from areas where high levels of the cancer-causing chemical trichloroethylene (TCE) have been detected.

Despite the state offering free testing, the company managing the facility has indicated that the landlord, Anthony Borruso, has not been cooperative in facilitating this process.

“I can’t give any comment on that,” Anthony Borruso, who owns the property at at 255-261 Douglass St., told The Post when asked if he has refused to test or would be testing the site in the future.

Some of the building’s roughly 75 tenants have since launched a GoFundMe campaign to pool more than a thousand dollars needed to run third-party tests.

Nearby sites such as the Royal Palms shuffleboard club on Union Street have been found to have cancer-causing vapors roughly 22 times the amount considered safe. Another building, which the state has not publicly identified, had levels of TCE 450 times above acceptable levels.

While the musicians’ fundraiser only amassed $820 of its $1,333 goal, the tenants moved forward with testing conducted by Exclusive Testing Labs and are now waiting on results.

“I’m thinking about moving out … but it’s tough for a musician to find a new space,” said one tenant, who declined to provide his name to The Post out of retaliation fears.

The musician told The Post that tenants put up flyers in the building to notify others of the fundraiser, but someone “tore them all down almost immediately.”

“Getting cancer or some other lung disease, that would be my big concern,” he said. “The long term health impact could injure me. This could kill me, even.”

While private lab testing isn’t enough to qualify for free state-funded cleanup, the musician said that, if the private lab returns “bad results,” then the group plans to sue the landlord.

The state is urging landlords around the canal site to test – but as of last fall, only 20% of landlords granted access for testing, records show, and building owners have the right to refuse testing from the Department of Environmental Conservation.

“While tenants can provide DEC access for their specific living space, DEC requires owner permission to complete a full [soil vapor intrusion] evaluation for a building,” a state rep said.

“I find it unethical and, quite frankly, immoral … that landlords won’t have much incentive to get this testing,” the tenant musician added.

The debacle calls to mind a similar battle waging in North Brooklyn at the Meeker Avenue Plume – where the EPA has similarly only gained access to about 20% of properties in the 45-block testing zone to test for chemicals like TCE.

“If tenants are having difficulty in this regard, I encourage them to reach out to my office for support with getting landlords to comply,” Council Member Shahana Hanif, who represents Gowanus, said in a statement, adding “tenants should not be forced to pay for this critical service out of pocket.”

A representative from Exclusive Testing Labs told The Post it has privately tested about 15 to 20 commercial and residential properties — at the request of both landlords and tenants — near the canal within the past year.

Reasons why landlords can refuse a test run the gamut, the rep explained, from older landlords unaware of environmental dangers to those who “don’t feel as though air quality is as big of an issue as it actually is.”

A rep for Band Spaces NYC named John told The Post it will continue its pursuit to get the landlord’s permission.

“We’ve spoken [to Borruso] at length about the issue several times and I have made clear that the Band Spaces renters are anxious to have the testing done,” he said, “so I believe they may eventually relent and allow the testing to proceed.”
