I'm unsure of where to look to change the water level marker symbol that shows up in the materials description column. As you can see I changed the marker in the header to appear solid, however the marker in the column is hollow.
The entity is a Discrete Graphic vs Depth column so that's what you'll need to be looking for in Report Design. I have mine to be set up so that immediate groundwater is the hollow graphic and static groundwater is solid graphic.
