I can see that you are using ShareThis Hoverbar on your website. A simple way to turn off hash from address bar would be change the following code on your website -
Change -
stLight.options({publisher: "d083c212-e330-416e-b1c6-ed1bc3fe5bd5", doNotHash: false, doNotCopy: false, hashAddressBar: true});
to -
stLight.options({publisher: "d083c212-e330-416e-b1c6-ed1bc3fe5bd5", doNotHash: false, doNotCopy: false, hashAddressBar: false});
If you want to turn off CopyNShare for the copied content as well, you can switch doNotCopy: true as well.
Hope this will resolve your issue.
