      "The Combined Lab List is titled for laboratories certified or accepted to perform analyses on public drinking water. It is not a private-well-owner directory.",
      "Municipal water-treatment-plant, water-department, water-works, water-resources, sanitary-engineering, and water-company laboratories were omitted because this directory is for private well owners and the list does not say those plants take homeowner samples. That omission is a directory choice, not a statement about their certification.",
      "Out-of-state laboratories on the same PDF (mostly PFAS, radiochemistry, Cryptosporidium, asbestos) were not tabulated here. They remain on the official PDF.",
      "Ohio Department of Agriculture Consumer Protection Laboratory and The Ohio State University Stone Laboratory were omitted as government/research laboratories; the list does not say they accept homeowner samples.",
      "Except for Mahoning County Board of Health, Well Labs Index has not independently verified that these laboratories currently accept private-well samples.",
      "Nitrate is marked Yes when the PDF lists Standard Chemistry (the legend includes Nitrate) or lists Nitrate/Nitrite by name. Trace metals are marked Yes when the PDF lists Trace Metals (legend includes arsenic, lead, manganese, and others). Contact the lab for the exact methods offered.",
      "The PDF is dated August 2026, rev. 8/13/2026. Certification can change. Confirm with the laboratory and Ohio EPA Laboratory Certification (dwlabcert@epa.ohio.gov, 614-644-2752)."
