KINGSTON, N.Y. -- An additional leak in the Washington Avenue tunnel is a new cause for concern. A potential second sinkhole due to the flow of groundwater rushing into the tunnel had crews busy on Tuesday.
“We’re looking at somewhere around 50 to 60 gallons a minute. We have a grouting contractor working in the tunnel right now and we’re trying to seal that flow,” said City of Kingston Engineer Ralph Swenson.
This new leak is about 85 feet away from the original, which is being blamed for a massive sinkhole that collapsed in April. Swenson says the relining of that tunnel is expected to be completed by next week, and the additional work underway on the new leak won’t interfere.
“We’re trying to correct it right now. It may require us to do some dewatering of the area so that ground water levels are controlled,” said Swenson.
This would entail the installation of groundwater wells to collect the water in an attempt to direct it into the tunnel. Officials say this would prevent further deterioration.
“There is a concern because we do have some infiltration of inorganic material in the treatment plant, but we're optimistic and we'll know in a couple of days whether we'll have to put in those de-watering wells,” said City of Kingston Mayor, Shayne Gallo.
If that happens, the city is looking at more than $100,000 repair and Mayor Gallo says that’s within the allotted $1.6 million budget. But as neighbors have been feeling the effects from the original sinkhole for months, the thought of another mess on the road has them alarmed.
“It is scary,” said resident Denise Kynoch. “I’m shocked.”
The roadway, which has been closed off since April, is not expected to reopen until next summer.
