The Comprehensive Testing Program shows the results of testing at the WNA facility for parameters
that the EPA and MA DEP require each facility to perform every nine months.
WNA has performed testing on a quarterly basis since the retrofit for the Town of North Andover. The facility
has tested for Mercury and Dioxin and Furans and the results show that the facility has complied with all
federal requirements.
The WNA facility has shown that the retrofit has contained the Mercury emissions well below the requirements
and have followed the department's annual Mercury rolling average reporting. The facility will now be testing
the Mercury emissions every nine months in following the state guidelines.
