Compatibility of agriculture and petroleum industry

Problems observed in the interaction of agriculture and the petroleum industry are discussed. A wide variety of chemicals are used at drill sites. Caustic soda, chromates, asbestos, crude oil, and thread collar compound (30-50% lead) can all cause cattle poisoning. Cattle can fall into mud pits and drown. Well fracking can lead to spillage of acids onto pasture or crop land. After well production, animal poisonings can occur from salt water or lead from oil and grease, and injuries can be caused by the moving parts of the pumper unit. Salt water ingestion is a common problem, and salt concentrations >1% in drinking water can cause salt poisoning. Arsenic- and chromate-based corrosion inhibitors can cause poisoning of cattle. Broken transmission lines and leakage of petroleums allow cattle access to these substances
