No authtceq

Texas Commission on Environmental Quality contamination, water, and air datasets. Public ArcGIS REST MapServer, no auth. Layers: - lpst (~30k Leaking Petroleum Storage Tanks) - pst (~19k active Petroleum Storage Tanks) - superfund (~170 state Superfund sites) - vcp (~3k Voluntary Cleanup), brownfield (~210), ihwca (~5.7k Industrial Hazardous Waste) - pws (~19k Public Water System wells), ww_outfall (~4.6k wastewater outfalls) - aqs (~230 air-quality monitoring sites) Counties stored UPPERCASE upstream; returned Title Case. PWS and AQS layers have no county field — pass bbox or near. getGroundwaterOverlay combines Edwards Aquifer + PGMA + GCDs in one call.
