Staff from various Berlin town departments work on Jan. 29 to clean up residual debris following the discovery last year of a caustic soda spill at Heron Park and prepare to reopen the property to the public. Chesapeake Environmental Services handled the bulk of the cleanup for $283,000. Other work was done by town workers and a few contractors at a cost of about $3,000 rather than the $50,000-$60,000 quoted by other contractors, said Town Administrator Jeff Fleetwood.
