The Atlas · Tarzana, Los Angeles County, CA
Water filtration in Tarzana.
Tarzana sits on the same LADWP distribution system as Woodland Hills, which means chloramine disinfection and a hardness load that comes primarily from the Colorado River share of the MWD blend. The seasonal groundwater contribution shifts the mineral profile slightly from month to month, which is one reason we run a free in home water test before specifying any equipment for Tarzana homes.
