RICHARD C. SLADE
President & Principal Groundwater Geologist
Major fields of hydrogeologic emphasis for Mr. Slade include groundwater resource development (basin-wide studies, and water well design and construction), and aquifer analysis. Principal projects have involved, evaluations of entire groundwater basins, aquifer test analyses, assessment of water quality problems and groundwater degradation, design of water wells for municipal supply, well rehabilitation assessments, monitoring of all phases of water well construction, locating and designing groundwater monitoring networks, and providing expert witness testimony for groundwater litigation. Considerable work has also been performed for numerous vineyards and wineries in both the Central Coast and Northern California regions; types of work have included feasibility studies for determining final locations for new wells, designing new wells, monitoring of the construction of new wells, working with drilling contractors, evaluating down-hole problems (such as sanding) in existing wells, and developing protocol for water well rehabilitation.
Hydrogeologic studies have also involved evaluation of hazardous wastes such as acid mine drainage, leachate from sanitary landfills, and groundwater degradation resulting from leaking underground storage tanks containing various chemicals and organic compounds. Numerous groundwater studies and monitoring projects have involved volatile organics (TCE, PCE, etc.) and subsurface gasoline spills. Hydrogeologic assessments and definition of appropriate mitigation measures for environmental impact analyses have been provided also. Important to Mr. Slade's broad background is the experience gained while being a participant with other geologists on international geologic study tours to Europe, Iceland and Scandinavia, the former Soviet Union, South America, the People's Republic of China, Africa, New Zealand and Australia. Local groundwater and surface water features, large faults and landslides, mines, and oilfields were visited in these countries.
In December 2008, based on the recommendation of the Administrative Committee (the water managers for the cities of Burbank, Glendale, Los Angeles and San Fernando, and the Crescenta Valley Water District), the Superior Court of Los Angeles County selected Mr. Slade as the new Watermaster for the entire Upper Los Angeles River Area (ULARA). Mr. Slade represents only the third Watermaster of ULARA since the date of the original adjudication of the region in January 1979.

GEOTECHNICAL CONSULTANTS, INC.
Consulting Groundwater Geologists
1970 - 1983
Joined the firm in 1970 as an engineering geologist and hydrogeologist. Advanced to Associate in 1975. Participated in and supervised geotechnical and hydrogeologic projects of various complexities, from the feasibility level through final design. His investigation and reports have analyzed faults and seismicity, earth materials, and groundwater problems for such facilities as dams, reservoirs, treatment plants, tunnels, industrial and residential buildings, sanitary landfills and groundwater basins. Major experience has involved field mapping, logging of bore holes, monitoring of groundwater observation holes, data analyses, and report writing.
Since 1972, Mr. Slade was the responsible hydrogeologist for several major groundwater basin projects including locating and designing of new wells and well redevelopments, calculations of groundwater in storage, determination of aquifer parameters, and evaluation of dewatering criteria. Several studies utilized emplacement of deep exploratory drill holes, analyses of geologic and geophysical data, and monitoring and analyses of groundwater levels, quality and pollution, and assessment of leachate and gases at existing landfills.
In addition, he conducted and supervised groundwater pollution studies and evaluation of several active and proposed sanitary landfill sites; he has supervised geologic and hydrogeologic studies for the evaluation and abatement of acid mine drainage from a large, inactive sulfur mine; and he has participated in assessing groundwater, geologic, and geotechnical parameters which affect sewer infiltration and inflow.
METROPOLITAN WATER DISTRICT OF SOUTHERN CALIFORNIA, Los Angeles
