Description: Aquifer texture represents a classification of surficial material grain size into 10 general categories for use in ground water applications. The aquifer texture attribute (TEXTURE) includes: fine, coarse, fine overlying coarse, and coarse overlying fine grained deposits, as well as artificial fill, beach, salt marsh, swamp, and water. Aquifer texture group (TEXTUREGRP) includes areas of fine grained , fine overlying coarse grained, coarse grained, and coarse overlying fine grained deposits. Surficial materials not included in the surficial aquifer texture groups include till, artificial fill, beach, salt marsh, swamp, and water. All textural terms follow the grain size classification of Stone et al 1992, modified from Wentworth, 1922. The surficial aquifer texture classifications are suitable for use at 1:24,000 scale.
