Oklahoma DEQ wellhead protection + remediation + monitoring. Native ArcGIS REST MapServers, no auth. - searchWellheadProtectionAreas ⭐ — drilling-restriction polygons (~5.9K) around PWS - searchRemediationSites ⭐ — Institutional Controls (~890) under formal cleanup programs - searchVoluntaryCleanupSites, searchAccreditedLabs (~151), searchAirQualitySites (28) - getServiceInfo quirks: WHPA has NO name / county / facility id — only ZONE (A/B/C) + SOURCE_IND. Filter zone or bbox. Remediation County values dirty (Garfeld vs Garfield, "Tulsa" vs "Tulsa County") — handler LIKE-matches + Title-Case strips trailing " County". LabAccred Lab_Type has typos. Base_Certification_Status always 'Accredited'. Air POLLUTANTS comma-joined; LIKE-matched.
