The engine was removed and the wooden hull was filled with concrete and tire units. The Good Times broke apart after only a few weeks on the bottom and is now completely disintegrated. The program has had enormous successes since this first small beginning.

Poly-chlorinated biphenols (PCBs) and heavy metals ( Pb, Cu, Ni, Cd, Zn, Ag, and Hg ) have become an issue of concern with artificial reef development, as popular reef building materials ( e.g., ex-Navy vessels ) may contain quantities of these toxic materials that may potentially be transferred through the food chain. This transference, or bioaccumulation, may have unforseen effects on the marine environment and, ultimately, human health through consumption of contaminated finfish and shellfish harvested from these reefs. However, thousands of ships have met their demise without the environmental cleansing and preparation that artificial reefs require, perhaps posing a potentially greater health risk to consumers and divers.
