7 scope of this investigation. It has been clearly evident over the last five decades that the risk/benefit ratio regarding pesticides has been overwhelming benefit and comparatively low risk to the United States population and to the environment, as a whole. Available environmental fate data for applied herbicides have been documented. This list illustrates environmental fate data, and indicates the half-lives of the listed materials are comparatively fast: Data was obtained from the Illustrated Handbook of Physical-Chemical Properties and Environmental Fate for Organic Pesticide Chemicals: DORMANT SPRAY Common name:Volk Petroleurn Oil.Half-lives in the environment: W/COPPER Air: unknown. Soil: selected field half-life is 30 d. Half life of 30d for aerobic degradation and 60 d for anaerobic degradation. ROUND-UP. Common name: Glyphosate.-Half-lives in the environment: Air: Unknown. Surface water: Half life> 9 wks. Groundwater: Unknown. Soil:.<60 d. - � s ROVRAL. Common Name: Iprodione. Fungicide. Environmental fate unknown. - Since the almonds are hard-shell, there is no organophosphate (OP) sprays for Navel Orangeworm (NOW). The Sipma's apply fertilizers carefully with the proper techniques and controls such as soil and leaf tissue analyses. This allows for an equal distribution of nitrogen, phosphorous and potassium (NPK) for crop uptake, thus preventing excessive leaching past the root zone. 5A - - CONCLUSIONS AND RECOMMENDATIONS From visual observations, there is no surface contamination. The probability of subsurface contamination from pesticides can be considered low- to-nonexistent, considering the referenced environmental fate data. The surface soil type (<5 ft) is predominately a loamy sand. The biological activity of this soil type would be expected to be slightly lower than in heavier clay- type soils, thus creating a medium environment for microbial decomposition of organic = molecules. Sandier soils may also promote nitrification. Due to the depth of the on-site domestic wells (180 ft and 280 ft), a multi-residue pesticide screen consisting of analysis for Dinitroanaline, Triazine, Organochlorine and Organophosphates would not be required. However, regardless of the well depths, bottled,water should be used for drinking and cooking in rural areas. The subject property is outside of delineated areas in which all new wells must have a grout seal to 200 feet. 4 k - Valky Ag Research
