I worked on this project over the course of a couple years with Val for her Agricultural Water Quality Research & Education program. Her focus was educating grove managers and agriculture professionals on the hazards of point and non-point source pollution due to water leaving their properties. Working for Val was great because she gave me the reins and said just go for it. You'll notice the icon in the first two example is different than the others and that's because once the program started to gain traction, I brought up the point that her program's logo didn't really hint at having an agricultural presence. Val agreed and I suggested adding the seeding graphic to the middle of the water drop and she was ecstatic with the result and could not believe how much impact such a little tweak could have.
