Infrastructure 
Lacking a municipal water supply network, residents have used water that comes from two wells that are contaminated with nitrate and Coliform bacteria. Tooleville is one of many areas in the Central Valley plagued for decades by contaminated drinking water caused by chemical fertilizers, animal wastes, and pesticides that have infiltrated aquifers. In 1973, the county general plan deemed as having little or no authentic future and that by withholding major public facilities such as sewer and water systems, the community would enter a process of long term, natural decline. Tooleville residents have sought water access through nearby Exeter, but Exeter officials declined to provide a connection to their water system for more than 20 years. In August 2021, the California State Water Resources Control Board sent a letter stating that the state would intervene if the city did create a consolidation plan within six months. Planning of a connection project started shortly thereafter, and the project is expected to take eight years to complete. References
