Noise from point light in ground-plane

[T4CRAIG]

Hi Guys/Gals,

So I cannot seem to find a way to get rid of the noise created by a point light - specs of blue scattered across the floor that don't smooth out.  I originally thought this was a samples issue, so I maxed the settings out and regioned rendered, but still to no avail.

The point lights are set behind a glass material.  I thought this might be the problem so I made sure any material sample settings were high.

My scene is currently setup using a studio HDRI, a ground-plane using a General material with some noise, and an opacity map on the ground plane so it gradients into the background.  The only thing I can think of is that this is a problem between the point light and roughness within the material.

Does anyone have any experience with this?  How can I clean up the illumination/ground reflection in that area?
