She has conducted extensive research on historical groundwater chemistry data and has analyzed the integrity of 15 wells in the Pavillion area. The work she has completed is sufficient to be converted to a technical manuscript for publication in the Journal of Petroleum Technology or another related peer-reviewed journal.Yours sincerely,'db:~.-:r.-s .

Inorganicions(e.g.,sodiumandpotassium) 2. Syntheticcompounds(e.g.,isopropanolandtriethyleneglycol)notfoundnaturallyin groundwater 3.
