Perchlorate contamination in groundwater is a concern owing to the likelihood that low concentrations of
perchlorate may disrupt normal thyroid function. Lawns fertilized with perchlorate-containing fertilizers can adverselyaffect groundwater. We examined perchlorate concentrations from June 2006 to January 2007 in precipitation, grass clippings, soil cores and soilwater at eight lawn environments in Suffolk County,NY, a countywhere lawns comprise more than 25% of the land use. Measured concentrations in soil waters were as high as 255 μgL−1, with average concentrations of 69 μgL−1 beneath sites treated with organic fertilizer, 1.2μgL−1 beneath sites treated with chemical fertilizer and 0.34 μgL−1 beneath sites not fertilized. Although concentrations were dependent on the type of fertilizer applied, the patterns of leaching and grass uptake were similar at all sites.
