Data

Source: https://doi.org/10.6073/pasta/570231c2807a6396ced6a89ef7547bd4
Location of sample data: The Luquillo Experimental Forest (LEF)
Sites used in the analysis:

• Quebrada uno-Bisley, Q1, Bisley stream
• Quebrada dos-Bisley, Q2, Bisley stream
• Quebrada tres-Bisley, Q3, Bisley stream Rio Mameyes Gage MG Bisley stream
• Puente Roto Mameyes, MPR, Bisley distributary stream (previously "PRM")

Findings

1. Concentration on NO3-N and K ions increase following a hurricane
   
2. Mostly positive correlation between ions of Mg, Ca, Na, K and conductivity.
   Additional analysis required:
   • Evaluate strength of correlation
   • Evaluate all other ions (NO3, SO4, PO4, NH4)
   • Confounding factors
3. pH level in stream water decrease following a hurricane
