In Umbraco Forms, you can set the Default Value of a field.

For example, set the Default Value to something like [@queryName]. The 'queryName' will be your querystring parameter name in the URL (http://www.website.com/contactus?queryName=Foo) - Umbraco does the rest.

I referred to this and it was pretty straight forward: https://our.umbraco.org/forum/umbraco-pro/contour/14340-Set-value-of-radiobuttonlist-from-querystring
