INTRODUCTION AND PURPOSE Of VISIT • This report describes the first hydrogeological visit in connection with the second phase of the UK-Kenya Rift Valley Geothermal Project. The visit was undertaken by W G Darling and D J Allen and was essentially a • hydrogeochemical sampling exercise, with the aim of establishing the • characteristic fluid chemistry of the accessible thermal areas located so • far, and of cold groundwater. • 2.

PROGRESS • The purpose of this visit was to carry out geochemical sampling of water and steam in the southern half of the Rift Valley Geothermal Project, Phase 2 • area. • Despite some unseasonally wet weather, a reasonably good coverage of the Korosi and Paka volcanoes was achieved, with most ef fort being devoted to • fumaroles at or near local boiling point (970 C). Owing to a general lack of wells only a few groundwater samples could be obtained, but surface water • in perennial and strong seasonal streams was sampled to assist understanding of the water balance of Lake Baringo, which has a probable subsurface • outflow through at least part of the project area. Samples were also collected from thermal and non-thermal manifestations outside the immediate • project area, principally at Lake Bogoria and on the Rift flanks, to provide a general context for the results. Details of sites and samples are given • in Table 1, Figures 1-3 and the Appendix to this report. Apart from basic properties (pH, temperature and electrical conductivity), all chemical and • isotopic measurements of the waters and gases collected will be carried out in" the UK following receipt of airfreighted samples. The results of these • analyses will be discussed in a subsequent report. • During the visit, discussion of the geochemical results from RVGP Phase 1 took place with Mr G Gislason, Chief Technical Adviser to the UNDP IDTCD • project. • 4. SUM4ARY AND fUTURE VORK • This visit was devoted to the collection of a representative suite of fluid samples from the southern part of the Phase 2 Geothermal Project area. The • principal area of interest centred on the Paka and Korosi volcanoes which • • • • • • • have numerous geothermal mani festations, but additional samples were obtained over a substantial area, ranging from Bogoria in the south to • Lorusio in the north and extending to the eastern Rift margins. • It is intended in future visits to extend the sampled area to include the less accessible volcanic centres to the north. In addition further sampling • in the Paka-Korosi area may be necessary. Time will also be spent obtaining • physical hydrological data relevant to the project area. • • • • • • • • • • • • • • • • • • • • • • • • • • • ---- • • • • • TABLE 1 - SAMPlE DETAILS R.V.G.P.
