Emergency Biohazard Cleanup Near Downtown Grayson Grayson, CA

Grayson is an unincorporated community and census-designated place in Stanislaus County, part of the Modesto metropolitan area in California's San Joaquin Valley.

The town, also known over the years as Graysonville or Grayson City, was founded by a company of seven men that included Andrew Jackson Grayson, who brought his family to California in 1846.

Andrew Jackson Grayson became a self-taught watercolor painter and a leading authority on Pacific Coast birds, earning a reputation as an 'Audubon of the West.'

Graysonville served as a steamboat landing on the San Joaquin River from the Gold Rush era until river traffic ended as the water was diverted for agriculture.

The community sits where the San Joaquin and Tuolumne rivers converge, on just 0.18 square miles of land.

Grayson's groundwater is polluted by nitrates, so its drinking water is treated by ion exchange before it reaches residents' taps.

The 2020 census counted 1,041 residents in Grayson, up from 952 in 2010, packed into its tiny area at more than 5,600 people per square mile.

Grayson has 267 households with a large average size of about 3.9 people, and about 89% of its residents are Hispanic or Latino.
