Uncertainty was incorporated into all assumptions and data for each parameter by introducing a range of 5-25% of uncertainty distribution depending on the data availability and level of confidence. The incorporated uncertainties capture variation in the values for all the data points, e.g., fluctuation in materials cost and impacts. To address and quantify uncertainty, a total of 10,000 Monte Carlo simulations were conducted. Sensitivity analysis was performed to determine factors and parameters that are key drivers to changes in system's cost and environmental impacts. Specifically, we used the Spearman's rank correlation coefficients to measure and analyze the sensitivity of individual parameters for all units. Here, we report the absolute value for the top five Spearman's rank correlation coefficients (> |0.05| and p-value < 0.05) for total cost and GWP for each technology in each water.
