Are You Ready For Sampling Your Nearest River?

Before you go out to explore, first make sure you have all of the below:

Be Safe!!!

There are many animals in the river like snakes and crocodiles and in some deep waters there are hippos!

Make sure you are wearing protective shoes before you go in the river. There are many sharp rocks under the water.

miniSASS does not measure whether the water is fit to drink. A good miniSASS score means that the river has environmentally healthy water. Do not drink the water.

Check on this List:miniSASS Checklist

Life jacket (Especially if you cannot swim or when sampling from rivers with a strong current)

Soap / Hand wash



Net / Sieve   (See Below for how to make your own)


Timer (Remember you can only sample for 5 min)  

Magnifying glass

Ice cream Container / white tray   


How to Make Your Own Net

  • Take any piece of wire, for example an old clothes hanger, and bend it into the shape of a net. Then tie the netting (which can be any porous material) to the wire with a piece of string. And you have a net like the one below.
