Opposing the plans of expanding the state's largest toxic waste landfill, California's two U. S. senators on Tuesday called for a cessation of the plan. This statement related to the completion of investigations into birth defects in the nearby farm workers' community of Kettle man City.

Sen. Dianne Feinstein heading the Senate Subcommittee on Interior, Environment and Related Agencies said in a statement, "I have instructed my staff to go to Kettle man City and investigate this matter in order to ascertain what action might be taken immediately to clean up the polluted drinking water on which the people of Kettle man City currently rely. It is my view that there should be no expansion of the toxic dump site until we know with certainty whether it is a cause of this serious situation".

Drinking water needs to be improved for the reason that it contains high levels of arsenic in the soil of California and the same water is used in pesticides, herbicides, insecticides and metal alloys.

On the contrary Bob Henry, Senior District Manager for Waste Management of Kettleman Hills division sad, "This is the first we have heard Sen. Feinstein's suggestion. We believe our facility is safe, and we encourage an investigation into other possible causes of the birth defects so that Kettleman City residents can get the answers they deserve".
