Final answer:
Mario Molina, who won the Nobel Prize in Chemistry, did significant work on atmospheric chemistry related to ozone depletion, but there is no indication in the provided information that he worked on removing hydrocarbons from groundwater.
Step-by-step explanation:
The scientist who helped remove hydrocarbons from ground water is not explicitly stated in the provided references. However, the provided information highlights the work of Mexican chemist Mario Molina who shared the Nobel Prize in Chemistry in 1995 for his pioneering research on the Antarctic ozone hole. Mario Molina's work was primarily concerned with atmospheric chemistry, especially the formation and decomposition of ozone, rather than the remediation of hydrocarbons in groundwater.
While Mario Molina made significant contributions to environmental chemistry, his Nobel-prize winning work was focused on understanding the chemical processes affecting the Earth's ozone layer, particularly CFCs (chlorofluorocarbons) and their impact on ozone depletion.
