Nitrate Net

Nitrogen from agricultural runoff is a longstanding problem in the Chesapeake Bay, the estuary bordered by Maryland and Virginia. Now there is speculation that a rise in airborne nitrogen, possibly due to the proliferation of animal farms along the watershed, may be further compromising water quality. Unfortunately, data quantifying atmospheric deposition is sparse.

The goal is for students to secure valid data from testing for low-range nitrate and ammonia levels and measuring phosphate and pH in the airshed as well as in the watershed of the Chesapeake Bay. Data is downloaded from remote sites by way of AT&T wireless phones to a computer database. From there the data is automatically sent to a website, where information on the Nitrate Net is shared by all of the participating schools.
