other than several different types of discarded items. These items all appear to be non- hazardous. The site was carefully inspected for environmental concerns originating from discolored, disturbed or subsided soils, stressed vegetation(other than sprayed with herbicide), and unusual or noxious odors. None of these indicators were present. An important concern associated with the environmental assessment of agricultural properties is the issue of buried pesticide containers. It was an occasional practice to dispose of containers by this method many years ago. Detection of these types of underground artifacts is difficult-to- impossible even with the use of ground penetrating radar or other types of non-intrusive, subsurface analyses. The land surface did not exhibit visual indicators for buried containers such as surfacing of product residue, soil mounding or soil depressions. It can be surmised that due to the shallow hardpan in the area, it is doubtful that pesticide containers were buried in this locale. The static groundwater is found approximately 70 feet under the property, as illustrated on the attached groundwater map published in 1996. This is considered a comparatively deep elevation. Groundwater at this depth is not easily impacted from pesticides or nitrogen in the form of nitrates. The on-site soils consist of a medium to high clay content soil which can attenuate agrichemical residue in comparison to a sandy soil. The groundwater directional flow appears to be towards the northeast. To evaluate agrichemical residues as a nonpoint source of potential contamination,pesticide records were obtained for the last two years. These records can be found in the Appendix. The science of pesticide residues and persistence in soil, air, surface water and groundwater is extremely complex and variable. Environmental models which attempt to predict pesticide behavior and transport in the environment are beyond the scope of this investigation. It has been clearly evident over the last five decades that the risk/benefit ratio regarding pesticides has been an overwhelming benefit and comparatively low risk to the United States population, as a whole. Environmental fate data for the following pesticides applied to the subject property were obtained from the Illustrated Handbook of Physical-Chemical Properties and Environmental Fate for Orizanic Pesticide Chemicals: Diazinon. Half lives in the environment: Groundwater/sediment/soil: half-life in soil at pH 4.7 was 43.8 days, estimated persistence of 12 wks in soil. Biodegradation: half lives of 4.9 d at pH 3.1 and 185 d at pH 7.4 from river die-away tests. Half-lives of 32 d in 0-10 cm depth of soil by 100 d leaching screening test. Surface water: Hydrolysis half life> 185 d. Sevin 5 Bait. Common name- Carbaryl. Half lives/fate rate constants in the environment: Air:12.6 hrs based on vapor phase reaction. Surface water: 3.2 - 200 hrs based on aqueous hydrolysis half life at pH 9. 9 d under sunlight conditions for river water at pH 7.3. Less than 2 d at 22 C in darkness for filtered river water. Groundwater: 3.2-1440 hrs based on aqueous half-life at pH 9. Soil: 97-251 hrs in dry soil and 688-4458 hrs in wet or saturated soil. Biota: biochemical half-life of 22 d from screening model calculations. Phytolysis: half life of 52-200 hrs in the atmos. 3 Vaffey Ag Pf search
