Her husband does not know. I threatened to tell him and my husband responded with" what good would it do to destroy their marriage?"
I would not threaten at all, that is emotional blackmail. Instead, I would pick up the phone and call the OW's husband or go to his house and tell him in person. He needs to know so he can protect himself and his children from your husband and his wife.
And that is irrational to suggest that you would be destroying their marriage by telling him. I would have laughed out loud if I were you. He just told you that to manipulate you into not exposing him. That way, he can continue to pursue the OW.
I would then send a letter to Human Resources telling them about the affair. A letter should go to the Director of Human Resources with a cc to a key VP and the bosses of the affairees.

To Whom It May Concern:
This letter is to bring a matter to your attention that may be a violation of your Company's Code of Conduct and/or other policies, procedures and business ethics.
WS and WS are involved in an extramarital affair that is taking place, primarily, in the workplace. Aside from the potential sexual harassment claims this situation presents, it also involves the inappropriate use of company resources and assets. WS and WS are using company time and company resources to further their affair. If you check the call histories on their office and cell phones along with their workstation computers, you will find the two of them are spending an inordinate amount of what should be productive work time to further their sexual relationship.
If you have any questions, please call me at xxx-xxxx. Otherwise, I will anticipate a response from you once you have investigated these concerns and taken appropriate corrective action.
Regards,
BS
