The Atlas · Northridge, Los Angeles County, CA
Water filtration in Northridge.
Northridge, Reseda, Canoga Park, and the rest of the north Valley draw on a slightly different LADWP blend than the south Valley because of the San Fernando Basin groundwater wells in the supply mix. That gives the local water a different mineral profile than Woodland Hills, and it is one of the reasons we run a free in-home test before we spec a single piece of equipment.
The Water — Where it comes from
The local supply, in plain language.
Northridge is served by Los Angeles Department of Water and Power. The same LADWP blend that serves the rest of the city: State Water Project, Los Angeles Aqueduct, Colorado River via MWD, and local San Fernando Basin groundwater wells. Distribution in the north Valley draws on a larger share of local groundwater.
Common local concerns
- · Chloramine disinfection byproducts
- · San Fernando Basin groundwater contaminants in the historical record
- · Hardness
