The bronze sculpture of Venus and Cupid is a working fountain in which water spouts through the open mouth of the dolphin and drips from the bottom of Venus' hair into a shell held by Cupid.  In 2002, a water treatment system was installed in the fountain in order to reduce the likelihood of the bronze metal reacting with deleterious ions, including chlorine. Prior to this, numerous treatments had been undertaken to address and impede the growth of bronze disease.  The water treatment system consists of several components, including ultraviolet lights to reduce bacteria levels, a calcite tank to buffer the water, a carbon filter to remove chlorine, ion exchange filters to deionize the water, and micron filters to remove sediment and particulates.  

While the system has lowered the levels of ions that contribute to the formation of bronze disease, calcium levels are still high enough to allow calcium carbonate deposits to form on the sculpture. Areas of light to heavy white deposits were present on the surfaces that are in contact with or close to running water, including the legs and feet of both figures; Venus' drapery and the bottom of her hair; Cupid's face, arm, and the shell that he is holding; the dolphin; and the base of the sculpture.

The majority of the white accretions were removed from the bronze surface by separating them from the coated surface with small wooden and plastic tools. After the removal, an old Incralac coating that was no longer adhered to the bronze surface was removed using acetone on cotton pads. A fresh coating of Incralac was applied to the surface with flat brushes.  Finally, two thin coats of wax were applied to the treated areas with round brushes and were buffed with soft cotton cloths.
