What is MS Department of Environmental Quality?

Mississippi Department of Environmental Quality MUSTER (UST + CERCLA) and 2024 Impaired Waters services on agency host. Five curated Feature Layers: layer 10 All MS Underground Storage Tanks (~11,913 active+inactive points — 7 STATUS values: Closed 4554, Closed Release 3079, Pre 88 = 2545, Active 1245, Confirmed Release 332, Unconfirmed Release 69, Unregulated 89; 3 RELEASE_STATUS values: No Release 8433, Closed Release 3083, Open Release 397; 83 distinct counties led by Hinds 913, Harrison 634, Lauderdale 488, Lee 411, Rankin 386); layer 12 GARD CERCLA / Brownfields (~2,280 points — 4 STATESTATUS values: SNFA 735, Inactive 268, Active 230, BNFA 35; 7 FEDERALSTATUS values incl. NPL 7 + NPL-Proposed 1 + NPL-Delisted 3 + NFRAP 10 + FNFA 13 + Archive 407; 3 TYPECLEAN values: VEP 467 voluntary evaluation, BF 61 brownfield, TBA 25 targeted brownfield assessment); MS2024ImpairedWaters/2 ms303d_2024l (~233 stream polylines — 8 POLLUTANT values led by Biological Impairment 191 + 202-BIOLOGICAL IMPAIRMENT 29 numeric variant + Sediment 6 + Pathogens 2; 8 BASIN values mixed UPPER and Title Case); /3 ms303d_2024p (~4 polygons — small reservoirs/estuaries); /6 TMDL_Complete_l (~621 polylines). §0 surprises: MUSTER service publishes the SAME UST data 5 times at different scale tiers (layers 0/4/6/8/20 are identical 2,988 active; 1/5/7/9/19 are identical 8,792 inactive) — handler exposes only layer 10 unified. MUSTER does NOT support offset paging (`Pagination is not supported.` 400 response on resultRecordCount/resultOffset) — handler iterates by OBJECTID range. BASIN column mixes UPPER ('BIG BLACK RIVER' 18) and Title Case ('Big Black' 4) for the same basin; POLLUTANT has duplicates with numeric prefixes ('Biological Impairment' + '202-BIOLOGICAL IMPAIRMENT'). Host agency host has been historically flaky — handler retries once on 5xx/HTML/socket-hang-up. ; Last verified live 2026-05-07.
