Track record

0health-based violations in the last 10 years

From EPA SDWIS. A clean violation history means no enforcement action was recorded; it does not cover contaminants without a limit.

Not in this recordDisinfection by-products weren't monitored in this dataset

No result is not a pass. Your utility's annual water quality report may list them, and a certified lab test covers your own tap.

Your household

Your tap can differ from the city record

The record describes water leaving treatment and samples across the system. Pipes, solder and fixtures inside a building can add lead the record can’t see, especially in older buildings with lead service lines.

Is this right for my home?

Choose your situation

Your path: I live in an older buildingLead from plumbing is the main question

Older buildings may have lead service lines, solder or fixtures. Lead is not in Palmdale Dist’s published record, so only a tap test tells you. Test first-draw water, then filter if needed.

Look forLead reduction: NSF/ANSI 53 (lead)

How to test your tap →

Your path: I care about PFASCheck what was tested

3 of 29 PFAS tested were detected in Palmdale Dist’s record (PFBS 4.5 ng/L, PFHxA 6.3 ng/L and PFPeA 4.6 ng/L). If PFAS matters to you, a filter certification names each compound it covers.

Look forNSF/ANSI 53 or 58, with each compound you care about named on the listing

PFAS in Palmdale Dist →

Your path: My water tastes of chlorineThe disinfectant is not in this record

Most utilities keep chlorine or chloramine in the pipes. A carbon filter certified for taste and odor reduces either; your utility can tell you which it uses.

Look forNSF/ANSI 42 (chlorine taste and odor)

Water treatment technologies →

Your path: I have scale or hard waterPalmdale Dist water is moderately hard (6.65 gpg)

Scale is a comfort and appliance issue, not a health one.

Look forSoftener: NSF/ANSI 44 (softeners)

Your path: I want the broadest reductionReverse osmosis at one tap

Reverse osmosis reduces many dissolved contaminants, including lead and minerals, at a single faucet, with some water sent to drain.

Look forNSF/ANSI 58
