Yep. I sure can. Anyone can. If you have $2200 to do a full range of metals and bacterial testing. Don't have that on me personally
However, independent studies done by the Salton Sea Authority, different university for the grad programs on sediment vs irrigation run-offs impacts, and the Regional Water Board had already been published back in 2007, 2009, and I believe there may have been in 2010. Differently concentration detected based on where the samples were taken. The safest levels are towards the Salton Sea Museum and northwest wards.
