results? Note date of last calibration curve constructed:
❑ Yes
❑ No
True values: ❑ pg/L ❑ mg/L
Obtained values: ❑ Ng/L ❑ mg/L
What program are samples analyzed on?

❑ Yes
❑ No
Are results reported between the facility's permit limit and the compliance limit of 50 pg/L?
If value is less than the low standard, report as "<x", where x=low standard conic.
