Informational vs compliance testing
Informational testing answers “what is in my tap?” for your own decisions. Compliance testing follows a rulebook — who collects, which methods, which lab — so a result can satisfy a statute or a closing.
Water Testing Finder helps you locate a certified lab from official lists. We do not collect samples, and we do not claim to perform compliance sampling for you.
Informational (homeowner)
You pick analytes, follow the lab’s bottle and hold-time instructions, and use the report to decide about filters, plumbing, or a follow-up. Useful. Not automatically accepted by every agency or lender.
Compliance and real estate
Safe Drinking Water Act work for public systems is a regulated world of approved methods and certified labs. Private real estate deals often point at state or local rules instead.
Example: New Jersey’s Private Well Testing Act (PWTA) requires sampling by a New Jersey-certified laboratory — the lab (or its authorized sampler) collects; a homeowner DIY bottle usually will not satisfy the Act. Confirm the current rule for your closing with your attorney and the lab.
What to ask before you ship
- Is this result for my information only, or for a named regulation / lender / closing?
- Who must collect the sample?
- Which certification and method codes does the receiving party require?
Official lab contacts: EPA certified laboratory contacts. County health / Extension may offer low-cost well screens that are informational only.
