Environmental chemistry and water treatment. Performed prelim<strong>in</strong>ary design of alternatives to<br />

deep well <strong>in</strong>jection at a site <strong>in</strong> Artesia New Mexico. Included nanofiltration/reverse osmosis, ion<br />

exchange, lime precipitation and solar ponds.<br />

Key member of a team evaluat<strong>in</strong>g and implement<strong>in</strong>g Russian technology for treat<strong>in</strong>g radioactive<br />

submar<strong>in</strong>e waters at a base <strong>in</strong> Severodv<strong>in</strong>sk, Russia. Chemical eng<strong>in</strong>eer<strong>in</strong>g advisor to vice<br />

president on the technologies for this jo<strong>in</strong>t Russian-LATA proposal.<br />

Cool<strong>in</strong>g tower retrofit. Evaluated operation of a cool<strong>in</strong>g tower and closed-loop water system.<br />

Made recommendations and retrofit the system such that water treatment could be done and antifreeze<br />

added (the last m<strong>in</strong>ute upgrade prevented freeze damage to this several million dollar<br />

facility).<br />

Professional Eng<strong>in</strong>eer <strong>in</strong> charge of the Hanford CERCLA disposal facility. This system<br />

percolates tritiated water through the vadose zone such that the tritium decays to <strong>in</strong>consequential<br />

amounts prior to enter<strong>in</strong>g the Columbia River. Reviewed the design, verified the groundwater<br />

model, and validated the computer code.<br />

Experience <strong>in</strong> uranium corrosion and spent nuclear fuel stabilization. Worked on the prelim<strong>in</strong>ary<br />

design of Hanford’s spent nuclear fuel stabilization project <strong>in</strong>clud<strong>in</strong>g prediction of radioactive<br />

and flammable gases, vacuum dry<strong>in</strong>g and water treatment design for the fuel storage bas<strong>in</strong>. Key<br />

member of the high level team.<br />

Chemical fixation and stabilization (CFS). Worked on design of the high level waste CFS system<br />

<strong>in</strong>clud<strong>in</strong>g EPA l<strong>in</strong>er test<strong>in</strong>g, dra<strong>in</strong>age calculations, l<strong>in</strong>er calculations, and coat<strong>in</strong>gs/barrier<br />

analysis.<br />

Led a team of experts to determ<strong>in</strong>e the problems occurr<strong>in</strong>g with a feed tank, mix<strong>in</strong>g pump.<br />

Found the solution, wrote an operat<strong>in</strong>g manual and provided officials with a lessons learned<br />

document.<br />

Numerous Hanford Tank Farm projects <strong>in</strong>clud<strong>in</strong>g <strong>systems</strong> eng<strong>in</strong>eer<strong>in</strong>g, tank vapor space<br />

composition estimation, and vapor sampl<strong>in</strong>g and analysis technology assessments. Worked with<br />

Dr. Carl Yaws, Lamar <strong>University</strong> an <strong>in</strong>ternational expert <strong>in</strong> solution properties of organic<br />

compounds <strong>in</strong> salt waters.<br />

Worked on the prelim<strong>in</strong>ary design of Hanford’s spent nuclear fuel stabilization project <strong>in</strong>clud<strong>in</strong>g<br />

prediction of radioactive and flammable gases, vacuum dry<strong>in</strong>g and water treatment design for the<br />

fuel storage bas<strong>in</strong>.<br />

Inc<strong>in</strong>eration study for a Hanford site. Evaluated <strong>in</strong>c<strong>in</strong>eration <strong>systems</strong> for deal<strong>in</strong>g with radioactive<br />

mixed waste and recommended the preferred system. Worked on team with <strong>in</strong>ternational and<br />

national experts.<br />

1987 to 1990 Pr<strong>in</strong>cipal Eng<strong>in</strong>eer: Kaiser Eng<strong>in</strong>eers, Richland, WA<br />

<br />

<br />

<br />

Remedial Investigations/Treatability Studies (RI/FS) under CERCLA. Project Manager for two<br />

RI/FSs at Hanford.<br />

Project Manager/lead process eng<strong>in</strong>eer, Hanford B-Plant evaporator distillate study. Provided an<br />

eng<strong>in</strong>eer<strong>in</strong>g study for deal<strong>in</strong>g with the evaporator distillate. Contacted other DOE and EPA sites<br />

to assess the potential for technology <strong>transfer</strong>. Exam<strong>in</strong>ed all of the alternatives and determ<strong>in</strong>ed<br />

ion exchange as the best.<br />

Consultant for the Hanford 300 Area Chemical Sewer design. Effort <strong>in</strong>cluded consultation on the<br />

design of a treatment facility to remove radionuclides, metals, and organic compounds. Design<br />

used IX, filtration, pH adjustment, and a UV/H 2 O 2 reactor for organic compound destruction and<br />

removal.<br />
