Hydrogeology expert witness in Indianapolis and Central Indiana
Indianapolis-area wellfields draw from glacial sand and gravel along the White River and its tributaries, over carbonate bedrock. That makes plume migration toward production wells a recurring question, alongside solvent and vapor intrusion claims from the region’s manufacturing and dry cleaning history.
At a glance
Wetstone Solutions holds Indiana professional geologist licensure and supports hydrogeology expert witness and environmental litigation work in Indianapolis and Central Indiana: chlorinated solvent plumes, vapor intrusion, wellfield and wellhead protection, and challenges to IDEM decisions.
Central Indiana matters that need hydrogeology
These are the dispute types that most often need a Indiana PG hydrogeologist or expert witness in this region. Named sites are regional context, not a list of Wetstone engagements or claimed outcomes.
Chlorinated solvent plumes
Manufacturing, automotive, and dry cleaning operations left TCE and PCE plumes beneath parts of Indianapolis. Source allocation and commingled plume disputes depend on heads, chemistry, and timing.
Vapor intrusion claims
Solvent plumes beneath homes and businesses drive vapor intrusion claims. We assess whether groundwater conditions support the alleged exposure pathway and whether investigations were adequate.
Wellfield and wellhead protection
Production wells in the outwash aquifers can capture nearby plumes. Capture zone, travel time, and protection area questions need aquifer testing and a calibrated model.
IDEM permits and the Office of Environmental Adjudication
Indiana Department of Environmental Management decisions can be appealed to the Office of Environmental Adjudication. We review the hydrogeologic basis of permits, orders, and remedy decisions.
Glacial geology and preferential pathways
Interbedded till and outwash create sand stringers and windows that can short-circuit expected flow. We test whether the boring logs support the layering a model assumes.
Brownfield redevelopment
Redevelopment of former industrial parcels can reopen questions about residual contamination and prior investigations. We help counsel separate defensible data gaps from overclaimed certainty.
Central Indiana counties we support

Frequently asked questions
- Is Wetstone licensed in Indiana?
- Yes. Wetstone maintains Indiana professional geologist licensure and supports Central Indiana hydrogeology matters, subject to conflicts, scope, and licensing rules.
- Can you support an appeal before the Office of Environmental Adjudication?
- Yes. Wetstone can review the hydrogeologic basis of an IDEM permit or order, prepare expert reports, and support testimony, subject to conflicts and scope.
- How do you evaluate whether a plume threatens a wellfield?
- We combine aquifer testing, heads, and plume chemistry with a calibrated flow and transport model to estimate capture zones and travel times, and we document the uncertainty in those estimates.
- Is Wetstone local to Indianapolis?
- No. Wetstone is based in Western Pennsylvania. Site visits, depositions, and hearings in Central Indiana are scheduled per matter.
