Today, one part per trillion, or 1ppt, has become a reality - and one part per quadrillion isn't far away. All the while, ZERO keeps getting smaller. These scientific achievements, while commendable, fuel consumer fears of pesticide residues, toxic waste or any number of possible contaminants. It is important we remember that just because a chemical can be detected at a lower level, the level of risk for contamination does not necessarily change. The ability to detect residues at lower concentrations translates into the ability to research risks and benefits at lower concentrations.
Industry is committed to using new technology to continually assess and update risk analyses.
With this commitment, safe recommended usage levels can continue to be developed through extensive testing. When thinking about detectable levels, consider the following as a way to put it all in perspective. See our 1998 Water Quality Report for a list of the constituents we test for.
