  <dc:description>&lt;p&gt;Ground-water samples from two heavily fertilized sites in Suffolk County, New York, were collected through the 1978 growing season and analyzed for nitrate-N concentrations and nitrogen-isotope ratios. Six wells were at a potato farm; six were on a golf course. The purpose of this study was to determine whether the&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;sup&gt;15&lt;/sup&gt;N/&lt;sup&gt;14&lt;/sup&gt;N ratios (δ&lt;sup&gt;15&lt;/sup&gt;N values) of fertilizer are increased during transit from land surface to ground water to an extent which would preclude use of this ratio to distinguish agricultural from animal sources of nitrate in ground water.&lt;/p&gt;</dc:description>
