The Cote D'Voire is indeed by far the world's largest cocoa producrer. Main cocoa producing countries Lead gasoline is considered one possible source of lead in cocoa--in places where beans are routinely dried on raodsides. Naturally occurring lead in soil, however is considered the prime sourse.

According to the CSI episode that delt with this (I know, I know), it's not the water from a tap. They're gas is still leaded, the exhaust gets into the atmosphere, and when it rains, the lead is in the rain, and gets into the plants that way.

Unfortunately for CSI, it appears that lead is not a great problem. It is not readily soluble and does not get taken up by plants easily.
"Lead, on the other hand, is very insoluble in soil and is not readily taken up by plants. The major pathway by which lead enters the human food-chain is by direct ingestion of lead-contaminated soil or lead-containing materials. Lead poisonings of children in urban areas from ingestion of contaminated soil or lead-based paints have been reported. Soil contamination has been attributed to accumulation from paint debris in urban renewal areas and atmospheric deposition of lead from automobile emissions in high intensity transportation areas."
"This demonstration entailed the extraction of lead contamination from soil using in-situ phytoremediation in a manner that was both practical and economically feasible. Phytoremediation is a process in which ionic, or non-particulate, metals are removed from the soil by plant roots. A chelating agent (EDTA) and soil acidifier (acetic acid) were used to convert the lead into a water-soluble state amenable to plant uptake."
