The state Department of Environmental Protection has confirmed that a sinkhole in Harrisburg caused raw sewage to back up and spill into the Susquehanna River.
A DEP spokeswoman said Friday that silt and mud from the sinkhole on North 4th Street created a clog in a sewage overflow chamber, which resulted in a spill of 1,913 gallons on January 1 and a second overflow of 574 gallons on January 3.
The spokeswoman said the amounts are relatively small as far as overflows go. She added that city officials notified DEP within a timely manner.
She said any possible health hazard would be minimal because the amounts are small compared to the river flow, and there is very little recreational use of the river during this time of the year.
