Mississippi Department of Environmental Quality MUSTER (UST + CERCLA) and 2024 Impaired Waters via opcgis.deq.state.ms.us. 5 curated layers covering petroleum tank sites, brownfield/CERCLA sites, 303(d) impaired waters, and completed TMDLs. - searchUSTSites ⭐ 11.9K active+inactive UST facilities - searchCERCLASites ⭐ 2.28K state CERCLA / brownfields with NPL flags - searchImpairedWaters ⭐ 233 streams + 4 polygons on the 2024 303(d) list - searchTmdlCompleted, getServiceInfo §0 caught: MUSTER does NOT support offset paging — handler iterates by OBJECTID. 5 scale-tier duplicate UST layers — only layer 10 exposed. BASIN column mixes UPPER and Title Case. POLLUTANT has numeric-prefix duplicates. Host has been historically flaky — handler retries once on 5xx/HTML.
