 Summary
◦ Recycled Water Policy includes participation from
a variety of agencies
◦ Different programs and applications require their
own methods and analytes to meet regulations
◦ Lab Accreditation is by method and matrix
◦ Permits attempt to cover as much as possible,
even chemicals of concern that do not appear on
any previously regulated methods
