UHL & Associates, Inc.: Senior Hydrogeologist & GIS Expert, 2006 to present
Dept. of Geology, University at Buffalo: Research Assistant, 2003 to 2006
Netherlands Assisted Project Office, India: Hydrogeologist, 1999


Ashish Daw is a hydrogeologist and GIS expert with a Bachelors Degree in geology, and a Masters Degree in Applied Geology. He has completed graduate studies in Hydrogeology at the State University of New York, Buffalo. Mr. Daw began his career as a hydrogeologist with the Netherlands Assisted Project Office in Hyderabad, where he participated in a project to identify areas of wells in the State of Andhra Pradesh with acceptable fluoride concentrations, and set a framework for sharing and distributing high quality water.

With UHL & Associates, Mr. Daw has performed and managed many water-supply related and environmental projects. He has installed and tested numerous municipal and private commercial water-supply wells in bedrock and unconsolidated settings. He managed a highly successful well redevelopment program to restore capacity of a major 1.4 MGD production well critically needed by a large water utility. Other programs of note have included installing test wells to assess the feasibility of extracting and filtering river water during periods of high-flow by horizontal collector wells, and drilling bedrock wells up to 1000 feet (300m) to reach into an abandoned iron-ore mine being considered as a possible water storage reservoir.

Mr. Daw has sited wells using state-of-the-art methods, including the identification of lineaments and faults from aerial photographs, and working closely in the field with geophysicists. He has evaluated hydrogeological properties and aquifer characteristics through research of scientific data databases, and the implementation and analysis of long and short-term pumping tests. He is experienced with analytical and numerical groundwater models and their applications, and created an analytical element model (AEM) for simulating groundwater flow and contaminant transport that supported a water allocation permit issued for a production well by the state of New Jersey.

Internationally, Mr. Daw has recently implemented a project to select and sample 200 water-supply points in the capital city of Monrovia, Liberia, where he led the field team and trained local staff. His expert GIS skills have been tapped to create fundamental base maps and related databases for many groundwater supply projects conducted for large development entities (World Bank, USAID, ADB), including projects in Liberia, Afghanistan, Sri Lanka and Lebanon. He has processed and interpreted satellite images to identify potential well drilling sites for projects in Afghanistan, Cameroon and Sri Lanka.

Mr, Daw is very proficient in GIS systems and AutoCAD. He has prepared numerous field maps, complied geo-databases, and constructed detailed 2D and 3D specification drawings.

Mr. Daw is fluent in English, Hindi, Marathi, and can communicate in various Indian dialects.


bulletWorld Bank Water and Sanitation Program (WSP), Monrovia, Liberia, 2011

Selected and evaluated 200 representative water points (kiosks, open hand-dug wells, hand pumps, drilled wells) in Greater Monrovia for the Liberian Water and Sewer Authority. The program involved preparing field maps of water point locations, assembling field teams, training field teams on proper sampling techniques and methodologies, collecting field parameters, and creating a GIS database of sampling results. Analysis for total coliform and E-coli was completed in a portable laboratory setup in Monrovia. Inorganic analysis was performed by the University of The Free State in Bloemfontein, South Africa.

The primary objective of this effort was to evaluate water-quality conditions at water points in Monrovia on a sample basis, classifying water points according to their level and type of contamination, and identifying causes and patterns of pollution.
