About Us
WATER SOURCE ASSESSMENT
In accordance with the Federal Safe Drinking Water Act, an examination of Lincoln Avenue's groundwater resources was completed in May 2002. This assessment aims to enhance source water protection by identifying potential contamination risks near water sources. The study determined that Lincoln Avenue's groundwater sources are vulnerable to activities associated with detected contaminants, including gas stations, dry cleaners, auto repair facilities, high-density housing and parking lots. Additionally, the groundwater is considered vulnerable to recreational area surface water sources, though no related contaminants have been detected.
An assessment of the surface water source completed in October 2000 found it vulnerable to recreation and low-density septic system use, as well as historic mining operations (though no related contaminants were detected). A complete assessment copy is available at Lincoln Avenue Water Company (564 West Harriet Street, Altadena, California 91001) or by calling (626) 798-9101.
WATERSHED PROTECTION
Every five years, MWD must examine potential contamination sources in the State Water Project and Colorado River per State Water Resources Control Board requirements. The latest watershed surveys were updated in 2015 (Colorado River) and 2016 (State Water Project). Colorado River water is most vulnerable to recreational activities, urban/stormwater runoff, increasing urbanization, and wastewater. Northern California's State Water Project sources are most vulnerable to urban/stormwater runoff, wildlife, agriculture, recreation, and wastewater.
WATER QUALITY STANDARDS
To ensure tap water safety, the USEPA and DDW establish regulations limiting contaminant levels in public water systems. Similarly, FDA regulations and California law set limits for bottled water contaminants. The water quality standards include:
- Maximum Contaminant Level (MCL): Highest permitted level of a contaminant in municipal water
- Maximum Residual Disinfectant Level (MRDL): Highest allowed disinfectant level
- Secondary MCLs: Standards protecting water's aesthetic qualities
- Primary Drinking Water Standard: MCLs and MRDLs for health-affecting contaminants
- Treatment Technique: Required process to reduce contaminant levels
- Action Level (AL): Concentration triggering treatment requirements
- Notification Level (NL): Advisory level requiring local government notification if exceeded

Company History
Lincoln Avenue Water Company has a rich history serving the foothills of Altadena, California. Beginning as a simple water distribution operation, it has evolved into a respected municipal water provider serving northwestern Altadena's unincorporated community.
Settlement of Altadena and surrounding areas became possible in the 1860s with the development of Pasadena's first water sources. As citrus groves and farms flourished along the foothills, water demand steadily increased. To address growing needs, five prominent Altadena families—Woodbury, Webster, Clark, Hartwell, and Giddings—established the Millard Canyon Water Company. The area's name combines "Alta" (Spanish for upper) with "Dena" from Pasadena.
On March 2, 1896, Lincoln Avenue Water Company acquired the Millard Water Company. Through additional acquisitions of the Pasadena Improvement Company and water rights in El Prieto Canyon, Lincoln Avenue continued developing its infrastructure. The company drilled its first groundwater well in 1913, followed by a second in 1917.
During the 1920s population boom, Lincoln Avenue transitioned from agricultural water services to becoming a dedicated municipal water utility. This growth prompted the drilling of third and fourth wells. By the 1970s, the utility operated five wells and eleven water reservoirs.
As municipal water standards evolved, Lincoln Avenue faced contamination challenges. In 1984, hazardous substances were detected in some wells due to proximity to the Jet Propulsion Laboratory (JPL). Prioritizing resident safety, Lincoln Avenue closed affected wells. In 1992, a liquid phase granular activated carbon adsorption system was installed to treat contaminated groundwater. When another contaminant was discovered in 2004, the company worked with JPL and NASA to build an Ion Exchange Perchlorate Removal System—the first in Los Angeles County to receive State Department of Public Health certification.
Today, Lincoln Avenue provides water to over 16,000 residents through 4,500 service connections while continuing groundwater remediation efforts to deliver safe, high-quality water to the community.
