Read this first

  • Copper The 90th-percentile result was 1.4 ppm, above the 1.3 ppm action level.
  • Lithium was found in one of 1 samples, highest 15.1 ppb. Above EPA’s health reference level of 10 ppb, a screening level rather than an enforceable limit.
  • Lead The 90th-percentile result was 0.05 ppb, below the 15 ppb action level. EPA’s health goal for lead is zero.

1 health-based violation since 2016. Details are below.

What handles it

What was found

Highlighted: above the health goal. Circled: above the legal limit in at least one sample. Every scale puts the legal line at its middle.

Copper

Comes from pipes, often your own

1.4ppm

90th percentile, 2008

The 90th-percentile result was 1.4 ppm, above the 1.3 ppm action level.

What handles it

EPA SDWIS, lead and copper monitoring periods ending 2003 to 2008. The pointer marks the latest period; each blue tick is an earlier one.

Lithium

Comes from the source

15.1ppb

Highest of 1 samples; found in one

Above EPA’s health reference level of 10 ppb, a screening level rather than an enforceable limit.

What handles it

No certification claim covers this compound yet.

EPA UCMR 5, samples taken on June 1, 2026. Each blue tick is one sample where it was found.

Lead

Comes from pipes, often your own

0.05ppb

90th percentile, 2023 to 2025

The 90th-percentile result was 0.05 ppb, below the 15 ppb action level. EPA’s health goal for lead is zero.

What handles it

EPA SDWIS, lead and copper monitoring periods ending 2014 to 2025. The pointer marks the latest period; each blue tick is an earlier one.

Also found, with no federal limit

EPA measured these PFAS to learn how often they occur. None has a legal limit or a health goal yet.

Tested and not found

Below EPA’s minimum reporting level in every sample taken from Feb. 13, 2025 to June 1, 2026. Not found means not measured above that level, which is not the same as zero.

What handles it

A certification covers specific claims, not a whole standard. Look for these claims on the certifier’s listing, not the box. Wording varies a little: NSF writes “Lead Reduction,” WQA just “Lead.”

  • NSF/ANSI 53

    Claims: Copper Reduction, Lead Reduction

    For: Copper, Lead

  • NSF/ANSI 58

    Claims: Copper Reduction, Lead Reduction

    For: Copper, Lead

At the tap, or for the whole house?

Lead and copper usually come from pipes and fixtures inside or near your home. A whole-house system sits where water enters, so it cannot catch what your own plumbing adds after it. For those, the filter that counts is the one at the tap. How whole-house systems compare.

What this report cannot tell you

  • Levels of everything else. Federal bulk data carries results for PFAS, lithium, lead and copper, and violations for the rest. Nitrate, arsenic, disinfection byproducts and other levels are in Camp Pendleton (North)’s own annual report, which it must send you every year.
  • Your own plumbing. Lead results are the 90th percentile across homes the utility samples. Your home’s service line, solder and fixtures decide yours. A certified lab test is the only way to know.
  • Anything after the latest data. SDWIS data is from 2026 Q2; UCMR 5 samples are from Feb. 13, 2025 to June 1, 2026.
