For the individual well trend plots, what is the advantage of using nonparametric statistics over traditional linear regression techniques (monotonic trend fitting approaches)?

The use of non- parametric statistics allows the analysis of cyclical trends in groundwater solute concentrations (e.g. concentrations that increase and decrease through time). For example the Mann Kendal function, which is commonly used to evaluate trends in groundwater solute concentrations, is a monotonic function that cannot fit cyclical variation/ short term fluctuations.
