During her tenure as CEO of American Water, Hardwick led sustained capital investment focused on infrastructure renewal and system resiliency, advanced a long‑term enterprise capital plan, and oversaw acquisitions of water and wastewater systems across multiple regulated states. Earlier in her career, she served as a senior manager at Arthur Andersen & Co. and progressed through corporate finance and accounting leadership roles at Cinergy Corporation.
