Haloacetic acids (HAA5), total trihalomethanes (TTHM) and arsenic: New Jersey’s yearly averages per water system, as CDC’s Environmental Public Health Tracking Network publishes them, 2020 to 2023, with EPA’s 2012 to 2019 file for earlier years.

Nitrate, fluoride and chromium (total): EPA’s compliance monitoring file, samples taken from April 24, 2012 to April 2, 2019. Newer results are in the utility’s annual water quality report.

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.”

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 can’t tell you

  • Everything else. Haloacetic acids (HAA5), total trihalomethanes (TTHM) and arsenic results here are New Jersey’s yearly averages as CDC publishes them, from 2020 on, with EPA’s national file for 2012 to 2019. Nitrate, fluoride and chromium (total) come from EPA’s file alone, which ends in 2019. MT Olive Twp WD Pinecrest’s own annual report, which it must send you every year, has newer results for those and the contaminants this page does not show.

  • 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.

  • What it means for your health. This page reports what the records show and EPA’s limits and goals; it is not medical advice. If you are worried about a health effect, talk to a doctor or your local health department.

  • Anything after the latest data. SDWIS data is from 2026 Q3; UCMR 5 didn’t sample this utility; CDC’s yearly averages for New Jersey cover 2020 to 2023; EPA’s compliance samples are from April 24, 2012 to April 2, 2019.

Testing your own tap

MT Olive Twp WD Pinecrest’s results are for the water it sends out. What your own service line, solder and fixtures add shows up only in a test of your tap, by a lab New Jersey certifies.
