About Us
Your tap water undergoes regular testing for potentially unsafe levels of chemicals, radioactive materials, and microorganisms both at the source and throughout the distribution network. We conduct tests on various schedules—weekly, monthly, quarterly, or annually—depending on the specific substance being monitored.
State and federal regulations permit less frequent testing for certain substances whose levels remain stable over time. All water quality assessments are performed by specially trained technicians in state-certified laboratories.
Understanding Water Quality Standards
The Environmental Protection Agency (EPA) establishes limits on allowable substance levels in tap water. In California, the State Water Resources Control Board enforces these standards with limits that are often more stringent than federal requirements.
There are two types of limits, called standards:
- Primary standards protect public health by limiting potentially harmful substances
- Secondary standards address aesthetic qualities like taste, odor, and appearance
Regulations establish Maximum Contaminant Levels (MCLs) for each standard. The MCL represents the highest permitted level of a substance in your municipal water. California also establishes Public Health Goals (PHGs), which provide additional information about water quality but are advisory rather than enforceable.
Water Quality Reports and Monitoring
Our comprehensive testing covers over 100 substances, though regulations only require reporting those actually detected in your water. When reviewing water quality reports, compare the detected concentration levels against the MCL—any substance exceeding its MCL requires more frequent monitoring and potentially water treatment or source removal.

Park WC - Lynwood Municipal Water Company and EPAPark WC - Lynwood Municipal Water Report Info
The area now known as Lynwood traces back to 1810, when Don Antonio Lugo received a land grant of approximately 29,514 acres. He named it Rancho San Antonio, likely after his birthplace, El Mission San Antonio de Padua from 1775. The ranch bordered the pueblo de Los Angeles to the north, with its eastern boundary following the ever-changing Los Angeles River (then called the San Gabriel River).
Lugo maintained a residence in the pueblo de Los Angeles near the square opposite the church. He served as alcalde (mayor) of Los Angeles from 1816 to 1819 and was a prominent community leader. After receiving an official patent from the United States government on July 24, 1847, Lugo became the undisputed owner of Rancho San Antonio—Lynwood's birthplace.
Following Lugo's death in 1860, the rancho was divided among his eight children. His daughter Guadalupe inherited the area now known as Lynwood. She later transferred the land to a man named Heldman, who subsequently deeded it to M.A. Shields (wife of J.H. Shields) in 1871. The property eventually passed to Slauson, a prominent Los Angeles banker after whom Slauson Avenue was named.
In 1902, C.H. Sessions acquired approximately 400 acres and established a dairy and creamery. His wife's maiden name was Lynne Wood, inspiring them to name the enterprise "Lynwood Dairy and Creamery," located at what is now Sanborn and Long Beach Boulevard. The Southern Pacific Railway later established a siding here called the "Lynwood siding."
The Pacific Electric Railroad, organized by Henry Huntington in 1902, built a line from Los Angeles to Santa Ana between 1904-1905 that ran directly through Lynwood. In 1929, they installed a station at Long Beach Boulevard and Fernwood Avenue—a building that still exists today and is planned for historical landmark designation. The railway adopted the Lynwood name from the dairy and creamery.
