Water quality of Saigon rain
What is the water quality of Saigon rain?
Saigon had a huge downpour today. For some odd reason I decided to see what the water quality of the rain was. Since the rain was quite heavy, I was able to get a cupful of rainwater in a short time.
As you will see from the photo, the ppm was 7. Quite clean. No surprises here.
