Tool	Description
`searchUSTSites`	MS Underground Storage Tank sites (~11.9K active+inactive). Filter county (Title Case e.g. 'Hinds'/'Harrison'), status (Active/Closed/Closed Release/Pre 88/Confirmed Release), releaseStatus (No Release/Open Release/Closed Release), facilityName, city. Handler iterates by OBJECTID, MUSTER has no offset paging.
`searchCERCLASites`	MS GARD CERCLA + Brownfields (~2.28K). Filter county, stateStatus (Active/Inactive/BNFA/SNFA), federalStatus (NPL/NPL-Proposed/NPL-Delisted/NFRAP/FNFA/Archive/Inactive), cleanupType (VEP/BF/TBA), siteName, city.
`searchImpairedWaters`	MS 2024 303(d) impaired waters. geometry: lines (233 stream polylines, default) \| polygons (4 reservoirs/estuaries). Filter pollutant (Biological Impairment/Sediment/Pathogens/+), basin (case-insensitive, handler matches both UPPER and Title Case variants), waterBodyName.
`searchTmdlCompleted`	MS TMDL completed streams (~621 polylines). Filter basin, pollutant (TMDL_POLLUTANT), waterBodyName.
`getServiceInfo`	Schema, record counts (live), max-page caps, enum values for every filter, and §0 probe notes for any of the 5 curated layers.

About

Mississippi Department of Environmental Quality MUSTER (UST plus CERCLA) and 2024 Impaired Waters services on the agency host. Five curated Feature Layers: layer 10 All MS Underground Storage Tanks (~11,913 active and 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 including 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). Section 0 surprises: the 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), so the handler exposes only the unified layer 10. MUSTER does not support offset paging ('Pagination is not supported.' 400 response on resultRecordCount/resultOffset), so the handler iterates by OBJECTID range. The 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' plus '202-BIOLOGICAL IMPAIRMENT'). The agency host has been historically flaky, so the handler retries once on 5xx/HTML/socket-hang-up. Last verified live 2026-05-07.
