This study investigates changes occurring in pH and electrical conductivity (EC) for both precipitated and harvest ed rainwater through analysis of wet deposition and on-line measurement in storage tank. The study covers five months monitoring period where rainwater EC ranged from 3 to 50㎲/㎝ and pH varied from 4.1 to 7.0 most frequently from 5.0 to 5.50. Harvested water pH values were alkaline, resulting from direct corn tact with collection surface, then tend to neutralize along storage time. EC in storage tank increased from 150㎲/㎝ to 300㎲/㎝ indicating a slow release of soluble material coped
