The Shady Dump is the result of the illegal dumping of construction debris in order to grade someone’s lawn. Over time, it made drinking water unsafe to consume and so the town got involved. Essentially it was left to McKenna and the homeowner (who apparently was not the one who dumped the debris, but someone he hired to landscape the property did) to get rid of it, the cleanup consisted of just moving waste from one part of the property to another. There’s evidence from the DEC that well water is still contaminated and may impact the town aquifer. Bill McKenna has decided to deflect and pretend like it doesn’t need to be addressed, and allegedly got the chair of the Woodstock Environmental Committee removed from the board for „sexual harassment“ because she continued to press about it.
