Nitrate in Ground Water and Surface Water. Because nitrate is highly soluble in water it tends not to get filtered out like some other contaminants as the water seeps through the soil layers to the ground water level. How much nitrate will reach the groundwater zone from agriculture is determined by varying levels of crop watering and irrigation as well as changing levels of rainfall. Another source of nitrates in ground water is from human sewage disposal systems such as unmaintained septic... (read more)Browse Water Quality Testing Instruments Datasheets for Real Tech, Inc. -
