following endnotes are appended to method entries in subsections (a) and (b):
1
denotes
that, for the particular contaminant, the laboratory should substitute a
nitrogen-phosphorus detector for the electron capture detector in USEPA 505 (95)
(or use another approved method) to determine alachlor, atrazine, and simazine
if it needs a lower detection limit.
2
denotes
that the laboratory may not use Syngenta AG-625 (01) for atrazine in any system
using chlorine dioxide for treatment. In samples from all other systems, the
laboratory must confirm any result for atrazine using Syngenta AG-625 (01) that
is greater than one-half the maximum contaminant level (MCL) (in other words,
greater than 0.0015 mg/L or 1.5 μg/L) using another approved method and
additional volume of the original sample the supplier collected. If a result
from Syngenta AG-625 (01) triggers confirmatory testing, the supplier must use the
confirmatory result to determine compliance.
