Nitrate and nitrite enter water and soil through a variety of natural and anthropogenic sources.  The most significant sources for this project is the overuse of fertilizers on agricultural land and industrial animal farming.  Because of the high mobility of nitrate, it can move quickly through the soil and run off into nearby surface water.  The ability to quickly and inexpensively measure nitrate in soil and water could lead to early detection of run off and more responsible use of fertilizer.  The goal of this project is to develop a rugged, inexpensive microfluidic device for the measurement of nitrate/nitrite in both soil and water.   Our goal is to modify the Griess assay to a microfluidic platform which can then be analyzed using an inexpensive spectrophotometer or cell phone camera.   We present challenges we have overcome that involve filtration, reproducible detection and long term storage and stability.<br/>
