The Masai Mara is an area with a large amount of wildlife. All lodges that have wells should be testing them routinely for coliforms. This page provides many good examples of of other tests that should be done dependant upon the area that the well is located within.
This page illustrates all the naturally occurring sources of pollution as well as the sources of pollution caused by humans for drinking water wells.
Most of these tests are very inexpensive but they will provide your guests with piece of mind. If you want more information, hit us up and we would love to stop by and help out during our next sampling trip. There are several water testing facilities located within Nairobi or some tests you can do yourself such as this method. Information is key.
The preservation of the Masai Mara is of the up-most importance. All of the lodges play a very important role in raising awareness and preserving the beauty of one of the greatest spectacles of the world. Get informed.
