During last month's meeting of the Nesquehoning Water Authority, borough engineer, Ron Tirpak had reported on a letter received from DEP regarding some concerns at the fourth hollow. Last night, authority president, David Hawk, provided an update.

Hawk, along with Tirpak, Bill Hausman, Mark Lopata, Joe Conzenari and DEP representatives visited the fourth hollow together to discuss DEP concerns. In the letter, DEP addressed movement in the walls of the spillway as well as a boil occurring in the outlet stream.

During the group's tour of the area, there was no visible sign of a boil and it did not appear that there was any movement with the walls of the spillway. DEP, however, still has concerns that there may be some problems that are not readily visible that could contribute to dam and structure weakening, specifically with regard to rebar. DEP informed water authority members that they have seen similar situations in other areas that resulted in failure.

In order to identify any potential problems, monitoring holes will be drilled to determine water levels. X-rays will also be done on certain walls of the spillway to determine the integrity of the structure.

"If rebar is failing, we want to know it," said Hawk.

At some point, the authority may have to bring the entire dam up to current standards which will be an "expensive proposition" according to Hawk.

In other business, bids were opened for geotechnical boring tests to be performed at the new water tank site and at the site of the new booster pump station. A preliminary award was granted to American Geo Tech Inc. who provided the lowest bid at $6,400. This will be subject to the review and approval of engineer, Tirpak as well as Alfred Benesch & Co.

The authority also ratified the purchase of a new pickup truck. It is scheduled to be in by the end of the month.
