Projects

Field, modelling, and research work spanning pore-scale hydrogen storage, regional groundwater modelling, contaminated site investigation, health risk assessment, and environmental remediation.

01

Pore-Scale Hydrogen Storage in Basaltic Formations

Led pore-scale investigation of cyclic H₂–brine flow in Hawaiian basalt using micro-CT imaging and pore network modelling (PNM). Systematically evaluated how wettability, pore geometry, and repeated drainage–imbibition cycles govern hydrogen trapping, residual saturation, and recovery efficiency.

  • Residual H₂ saturation stabilised at ~61–62% after the 5th cycle, indicating hysteresis equilibrium
  • Shifting to weakly water-wet conditions improved recovery efficiency by ~6%
  • Land's trapping coefficients of 0.5–1.4 positioned basalt comparably to sandstone lithologies

02

Regional Groundwater Flow Modelling — Welland & Duffin Creek Watersheds

Reassessed municipal groundwater supply systems using MODFLOW to define resilient long-term frameworks for sustainable service delivery, accounting for projected population growth and quantifying resulting demand on groundwater availability and infrastructure.

  • Simulated hydraulic head distributions across both watersheds
  • Quantified water budget components and river–aquifer exchange
  • Scenarios informed municipal water supply planning decisions

03

Contaminant Distribution Mapping — Conceptual Site Model Refinement

Conducted spatial analysis following Phase I & II surveys on a community reporting heavy metal and PAH exposure linked to increased industrial and commercial activity. Mapped contaminant hotspots and delineated plume pathways to support remediation planning.

  • Identified distinct concentration gradients consistent with localized source influence
  • Spatial patterns aligned with groundwater flow direction and activity corridor proximity
  • Outputs used to refine the conceptual site model and prioritise monitoring locations

Probabilistic Health Risk Assessment — Heavy Metals in Groundwater

Investigated heavy metal concentrations (Pb, Cr, Fe, Al, Mn, Cu, Zn) in hand-dug wells and boreholes across Omu-Aran, Nigeria. Applied deterministic and Monte Carlo simulation methods to quantify carcinogenic and non-carcinogenic risks to adults and children.

  • Probability of HI exceeding 1 for chromium exposure: ~90% in children vs ~16% in adults
  • Boreholes identified as safe for both adults and children; hand-dug wells flagged as risk to children
  • PCA identified mixed anthropogenic and geogenic contamination sources

GIS Mapping & Groundwater Quality Assessment — Akure, Nigeria

Evaluated groundwater from 30 boreholes in Akure, Ondo State for domestic and irrigation suitability using Water Quality Index, irrigation indices (SAR, SSP, MH, KR), and Gibbs diagram analysis. Results mapped spatially using GIS.

  • 82% of samples rated "good" and 16% "excellent" by WQI for drinking purposes
  • 100% of samples rated excellent for sodium adsorption ratio (SAR); suitable for irrigation
  • Groundwater chemistry governed by rock–water interaction (Gibbs diagram)

06

Wastewater Remediation via Biosorbents — Nitrate Removal

Investigated nitrate removal from wastewater using chemically treated chicken feather fibre (MCF) as a low-cost biosorbent. Evaluated adsorption isotherms, kinetics, and the electrostatic mechanisms controlling anion uptake under varying pH conditions.

  • ~89.3% nitrate removal achieved under optimised batch conditions
  • Uptake governed by electrostatic attraction to positively charged surface functional sites
  • Performance strongly pH-dependent; reduced at high pH due to OH⁻ competition
