This dumping issue has great potential for a number of reasons I can think of:
The clean up alone will cost large sums of money, at a time when they can least afford it.
Property value of the Wallkill farm is greatly devalued.
Potential/probable lawsuits from former Bethelites, neighbors, indeed anyone who drinks water from that watershed. Can you say 'class action'?
This kind of news makes headlines, especially in a state like New York, with major metro areas downstream. The negative publicity will be hard to live down.
Tarnishes the squeaky-clean image that the Society has tried to build up and maintain.
Proves that they are and have been hypocrites. Bring to ruin those ruining the earth, indeed
Even die-hard witnesses will have a hard time explaining this one. There is simply no excuse for burying chemicals in the New York countryside.
If a firm/corporation is breaking the law in one area such as this, they are likely also guilty of other infractions, which the increased governmental scrutiny may bring to light.
The notoriety of this case will bring increased government attention to other printing facilities in other countries. There are likely to be environmental or other violations at other Bethel printeries.
