Water has been a contentious issue in California, both historically and to this day, particularly concerns over water supply systems ownership. The City of Pacific Grove (PG) currently has privately supplied water from the California American Water (Cal Am) company. PG and cities on the Monterey Peninsula within Cal Am’s water service area are considering switching to public water, as Cal Am charges high prices and has contributed to environmental problems in the area. As a part of the Sustainable City Year Program at CSUMB, this project involved collecting city data for over 100 California cities and conducting further analysis using that data. Throughout the state, we found that public water is more common than private water. Additionally, Monterey County has more cities with privately supplied water than any of the other counties from our data set. We also found that cities with publicly supplied water spent more on infrastructure, on average. Furthermore, there did not appear to be a significant relationship between a city’s water source ownership and income level, using both median income and per capita income. Because of the similarities between some cities with private water in Monterey County and the city of Ojai, which switched from private to public water, it is recommended that cities within Monterey County use Ojai as an example while they consider transitioning to public water. Felton should also be used as an example because it transitioned from private water from Cal Am to public water, even though Felton does not have many easily accessible data.
