Abstract/Contents:"Petroleum hydrocarbons (PHC) leaking from turfgrass management equipment onto golf putting greens may infiltrate underlying soil. Extent of infiltration and subsurface distribution of PHC in putting greens is unknown. Research was conducted to determine subsurface spatial distribution of PHC resulting from point-source surface spills. Four mL petroleum hydraulic oil amended with UV fluorescent dye was applied to the surface of 10.2 cm diameter x 15.2 cm vertical plugs taken from a TifEagle hybrid bermudagrass (Cynodon dactylon [L.] Pers. var. dactylon x Cynodon transvaalensis Burt-Davy) green. Plugs were sliced vertically at 0.5 cm intervals 48 h after treating. Digital images for the sequence of orthogonal two-dimensional slices were taken under UV light at 395 nm. Digital image analysis (DIA) was used to calculate cross-sectional area of the fluorescent plume in each slice. For one plume a quadratic curve was fitted to a sequence of 10 cross-sectional areas (R2 = 0.9799); solving the equation for zero gave start and end points for the curve of 0.0268 cm and 5.1048 cm. Plume volume of 68.6 cm3 was calculated by integrating the curve between these limits. Plume surface diameter was 5.1 cm; maximum vertical migration was 3.4 cm. This four mL point-source surface spill of petroleum hydraulic oil migrated vertically and laterally in soil forming a paraboloid plume that had expanded in volume > 1600% likely due to capillary and gravitational forces. Fitting an integratable curve with known zero limits to define plume boundaries appeared useful for determining the volume of PHC plumes in putting green soil. As other plumes may be asymmetric a method for establishing an integratable curve and integration limits to define the boundaries of PHC plumes with arbitrary geometry is needed."
