In 2010, carried an assessment of the Merti Aquifer in North Eastern Kenya (client- UNHCR) to determine its eastward extent with regard to water quality and quantity aspects for purposes of establishing a new refugee camp in Jalanjilla Division of Fafi district (an expansion of the Dadaab Refugee camps). In the process, 10 high yielding boreholes were sited and drilled which paved way for the establishment of the new camp and its field offices in Alinjungur Location, Fafi District. For instance the borehole at UNHCR offices in Alinjungur gave a tested yield (flow rate) of 43m3/hr, the high yielding borehole in the area.

In 2007, carried out aquifer contamination vulnerability mapping at Kimwarer Area, Kerio Valley for Kenya Fluorspar Company Ltd. The geophysical survey was conducted to determine any possible interaction between local aquifers and industrial tailing dams within the mine and thus any possible aquifer pollution.The study also included sampling and analyses of water samples from Kimwarer River.

In 2005, participated in Msambweni aquifer Study in Kwale District for Tiomin Resources Mining Inc. (Now Base Titanium Ltd). This included numerous hydrogeological/ geophysical surveys, water level studies, aquifer modelling and several exploratory and production borehole drilling phases. The overall objective of the study was to investigate the extent of the aquifer, aquifer characteristics, potential yield ranges of the Msambweni aquifer at various locations within the demarcated zones in providing the company with sustainable water for the Titanium Mining operations.

Moreover, impacts of high groundwater abstraction to the environment were investigated including saline water intrusion phenomena and adverse impacts to biodiversity with regard to the nearby Gongoni forest, Kichaka Simba, Mafisini an Buda forest and other water abstractors. During the study, carried out data inventory for over 50 boreholes/wells within the general locality and surroundings.
