Monte Carlo Simulation

Probabilistic Risk Assessment

KILLER FEATURE: Monte Carlo simulation quantifies uncertainty in risk assessments. NO competitor (GSI RBCA, GMS MODFLOW) offers this feature!

Concentration Distribution

Distribution Type

Lognormal is typical for environmental contaminants

μ (log-space mean)

Use ln(geometric mean)

σ (log-space std dev)

Risk Parameters

Risk Type

Reference Dose - RfD (mg/kg-day)

Example: Lead = 0.00035 mg/kg-day

Simulation Settings

Iterations

10,000 recommended (higher = more accurate)

Random Seed

For reproducible results

Configure parameters and run simulation to see results

Competitive Advantage: GSI RBCA ($395-850) and GMS MODFLOW ($2,815-21,000) do NOT offer Monte Carlo simulation. This is a unique VerSoil feature at $200-800/year!
