12 Unfiltered, no digestion or
					 hydrolysis.
13 Because MDLs reported in EPA
					 Methods 200.7 and 200.9 were determined using a 2x preconcentration step during
					 sample digestion, MDLs determined when samples are analyzed by direct analysis
					 (
i.e.
, no sample digestion) will be higher. For direct
					 analysis of cadmium and arsenic by Method 200.7, and arsenic by Method 3120 B,
					 sample preconcentration using pneumatic nebulization may be required to achieve
					 lower detection limits. Preconcentration may also be required for direct
					 analysis of antimony, lead, and thallium by Method 200.9; antimony and lead by
					 Method 3113 B; and lead by Method D3559-90D, unless multiple in-furnace
					 depositions are made.
14 If ultrasonic nebulization is
					 used in the determination of arsenic by Methods 200.7, 200.8, or SM 3120 B, the
					 arsenic must be in the pentavalent state to provide uniform signal response.
					 For Methods 200.7 and 3120 B, both samples and standards must be diluted in the
					 same mixed acid matrix concentration of nitric and hydrochloric acid with the
					 addition of 100 L of 30% hydrogen peroxide per 100 mL of solution. For direct
					 analysis of arsenic with Method 200.8 using ultrasonic nebulization, samples
					 and standards must contain 1 mg/L of sodium hypochlorite.

(2) SAMPLE
				  COLLECTION. Sample collection for the inorganic contaminants under s.
				  NR
				  809.11(2) shall be conducted using
				  the sample preservation, containers and maximum holding time procedures
				  specified in Table B. In all cases, samples should be analyzed as soon after
				  collection as possible.

1 For cyanide determinations
					 samples must be adjusted with sodium hydroxide to pH 12 at the time of
					 collection. When chilling is indicated the sample must be shipped and stored at
					 4 5C or less. Acidification of nitrate or metals samples may be done with a
					 concentrated acid or a dilute (50% by volume) solution of the applicable
					 concentrated acid. Acidification of samples for metals analysis is encouraged
					 and allowed at the laboratory rather than at the time of sampling provided the
					 shipping time and other instructions in Section 8.3 of EPA Methods 200.7 or
					 200.8 or 200.9 are followed.
2 P = plastic, hard or soft. G =
					 glass, hard or soft.
3 In all cases, samples should
					 be analyzed as soon after collection as possible.
4 Instructions for containers,
					 preservation procedures and holding times as specified in Method 100.2 must be
					 adhered to for all compliance analyses including those conducted with Method
					 101.1.
5 If the sample is chlorinated,
					 the holding time for an unacidified sample kept at 4°C is extended to 14
					 days.
6 Nitrate-nitrite refers to a
					 measurement of total nitrate.
(3) LABORATORY CERTIFICATION. Analyses under
				  this section shall only be conducted by laboratories that have received
				  certification under ch. NR 149 or approval by EPA.
(a) To receive certification to conduct
				  analyses for antimony, arsenic, asbestos, barium, beryllium, cadmium, cyanide,
				  fluoride, mercury, nickel, nitrate, nitrite, selenium and thallium, a
				  laboratory shall carry out annual analyses of performance evaluation samples
				  approved by the department or EPA.
(b) For each contaminant that has been
				  included in the performance evaluation sample and for each method for which a
				  laboratory desires certification, the laboratory shall achieve quantitative
				  results that are within the following acceptance limits:
