Western Laboratories specializes in agricultural water. The major problem with agricultural water is that it contains levels of nutrients that can restrict maximum crop production.  Our report contains guidelines that are simple to follow and generally need no further explanation.  




We also do E. coli and total coliform bacteria in water for your GAP program. For the GAP program we report the amount of total coliform bacteria and E. coli in MPN (Most Probable Number). We provide complete sampling kits with instructions. 




During the summer we have couriers going to E. Idaho and the Columbia Basin (WA) to bring the water samples that you collected. If we do not pick them up in your area, please keep the samples in a cooler with ice (no dry ice) and submit them to the lab asap.
