   A manager with KenGen, Mr Silas Simiyu, said the geyser disappeared from the surface after it caved in.
   
   The 80-metre geyser erupted in Chepkoyo village in April about 150 metres from the main road leading to Lake Baringo.
   
   Simiyu said investigations done by the company's experts revealed that the geyser collapsed internally.
   
   He said the soil and rocks blocked the opening from which the hot water was jetting out.
   
   "The soil and rocks reduced the pressure that was pushing the water out. The materials might have partially or completely blocked the opening," he said.
   
   He warned that the caving in of the geyser might lead to the ground sinking in.
   
   Simiyu warned residents and tourists from venturing near the geyser, as it was dangerous. He said the collapse was as a result of erosion on the walls of the borehole.
   
   The hot water from the geyser shot up before the casing of the borehole was complete thus eroding the remaining part. He said the water from the geyser was also eroding the soil on its surface, weakening the wall of the borehole.
   
   Simiyu at the same time said KenGen was conducting a major survey and analysis in the area to see whether they could establish a power station.
   
   "We have collected samples from the area and the results from tests will be through in a month's time," he said.
   
   Simiyu said they had to ascertain how big and deep the geothermal zone is before establishing a power station.
   
   Should the area not be viable for a power station, he said, the company would look for any other uses if any.

   According to the Kenya Electricity Generating Company's geothermal development manager, Dr Silas Simiyu, the exploration's latter phases will cover Mt Longonot, and from the Paka and Silale areas near Lake Baringo all the way to Lake Turkana.
   
   "Once the entire project is complete, KenGen will embark on drilling wells, field development and eventual installation of the power plants," he said.
   ...
   Dr Simiyu said that KenGen hopes to make geothermal the single largest source of power in the country. Officially known as the Joint Geophysical Imaging (JGI) Methodology for Geothermal Reservoir Assessment, the project's proposal was prepared by Unep, whose staff have also been providing technical and administrative advice in the project.

3. 3. Danger in Baringo geyser

   KenGen's geothermal development manager, Dr Silas Simiyu who released the results of the geochemical analysis, said the water is not suitable for domestic use and animals should not be allowed to drink the runoff water from the discharging well "until it has been controlled."
   ...
   Briefing journalists at the KenGen offices in Nairobi's Stima Plaza, Simiyu, explained that the geyser erupted because the casing was done using mild steel pipes, which are suitable for portable for water but cannot sustain the temperature and chemistry of the geothermal fluids.
   
   He said KenGen is now working with the Baringo County Council to have a separate borehole for domestic and other industrial uses, which he says will also help stabilise the area.
