What Is California Code § 1597.16(a)(1): Lead Water Testing?

California Code § 1597.16(a)(1)

A licensed child day care center, as defined in Section 1596.76, that is located in a building that was constructed before January 1, 2010, shall have its drinking water tested for lead contamination levels on or after January 1, 2020, but no later than January 1, 2023, and every five years after the date of the initial test.

💬What Providers Tell Us

Based on community experience — not official guidance

Inspectors ask for your lead test results and check two things: the lab certification and whether you tested every water source children can access. They walk the facility and count taps, then compare that to your report. If your test results show three fixtures but they see five accessible faucets, that's a citation. The five-year retest deadline is based on your initial test date, not a fixed calendar year, so every facility has a different due date. Put the next test date on your license renewal reminder. Los Angeles and San Mateo counties are seeing the most citations right now, often because facilities tested once and forgot about the retest cycle.

What Other Providers Do for Lead Water Testing

Common practices shared by providers. Confirm requirements with your licensing analyst.

✓ Common Practices

Test ALL drinking water sources (fountains, kitchen taps, classroom sinks)
Initial testing must have been completed by January 1, 2023 (if you missed this, test NOW)
Retest every 5 years from the date of initial test
Use a state-certified laboratory for testing (not home test kits)
Keep test results on file and available for inspection

❌ Common Mistakes

Testing only the kitchen faucet and ignoring classroom sinks, bathroom taps, and drinking fountains. Inspectors compare the number of water sources in your facility to the number on your lab report. Every fixture a child could drink from needs its own test.
Using a home lead test kit instead of a state-certified laboratory. The results from retail kits aren't accepted by CCLD. Contact your local water utility first since many offer free testing for licensed childcare facilities.
Assuming that installing a water filter or providing bottled water exempts you from testing. The regulation requires testing your building's plumbing regardless of filtration or alternative water sources. Inspectors will still ask for lab results.
Losing track of the five-year retest deadline. Since the cycle is tied to your initial test date (not a universal deadline), providers forget when they're due. Set a calendar reminder for four years and six months after each test to give yourself time to schedule the next one.

Frequently Asked Questions

Answers based on public CCLD data and regulation text. May not reflect recent changes.

What is Lead Water Testing?

California Health and Safety Code 1597.16(a)(1) requires licensed child care centers in buildings constructed before January 1, 2010, to test all drinking water sources for lead contamination every five years. This covers every fixture a child could drink from: kitchen taps, classroom sinks, bathroom faucets, and drinking fountains. For your daily operations, it means scheduling lab-certified testing on a recurring cycle tied to your initial test date, not a universal deadline.

How common is this citation?

According to California CCLD inspection records as of March 15, 2026, 25 facilities have been cited for this violation in the past 90 days across 12 California counties. That's roughly 1 in 1,600 inspected facilities. Los Angeles leads with 6 citations, followed by San Francisco (4), San Mateo (3), and San Diego (3). Many citations stem from facilities that completed the initial test but missed their five-year retest deadline because the cycle is tied to each facility's own test date.

What triggers this citation during an inspection?

Inspectors ask for your lead test lab results and then walk the facility counting every water source children can access. Based on CCLD inspection patterns, the most common triggers are testing fewer fixtures than the inspector can count, using a retail home test kit instead of a state-certified lab, and missing the five-year retest window. If your report shows three fixtures tested but the inspector sees five accessible taps, that's an immediate citation. Having a water filter or providing bottled water does not exempt you from testing.

How can I prevent this citation?

Walk your facility and count every water fixture a child could reach, then make sure your lab report covers each one. Use a state-certified laboratory, not retail test kits. Contact your local water utility first since many offer free testing for licensed childcare facilities. Set a calendar reminder for four years and six months after each test date so you have time to schedule your next round before the five-year deadline hits.

What should I do if I receive this citation?

Schedule testing with a state-certified lab immediately. Test every water source children can access, including fixtures you may have missed the first time. Keep the lab report on file and provide a copy with your Plan of Correction showing the test date, lab certification number, and results for each fixture. Mark your calendar for the next five-year retest. For complex situations, consider consulting a licensed childcare compliance specialist.
