  Analytical Methods Approved for Drinking Water Compliance

  Monitoring of Inorganic Contaminants and Other Inorganic

  Constituents
  Analysis for the following contaminants and other constituents shall be conducted in accordance with the methods in the following table, or their equivalent
  as determined by EPA. The methods are specified in 40 CFR 141.23 and Appendix A to SubpartC of Part 141. The monitoring requirements are specified
  in 40 CFR 141.23, 141.41,141.86 - 141.88, and 141.135.
  The CFR is the legal reference for approved methods and takes precedent over this table. The table should accurately reflect the analytical methods
  information published in 40 CFR 141. If you find discrepancies, please notify The Safe Drinking Water Hotline (800-426-4791) so that EPA can correct the
  table.

                                         determined when samples are analyzed by direct analysis (i.e., no sample digestion) will be higher.
                                         Preconcentration may be required for direct analysis of antimony, lead, and thallium by Method 200.9

                                    If ultrasonic nebulization is used in the determination of arsenic by Method 200.8, the arsenic must be in the pentavalent state to provide
                                    uniform signal response.  For direct analysis of arsenic with Method 200.8 using ultrasonic nebulization, samples and standards must contain
                                    one mg/L of sodium hypochlorite.

   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 by Method 200.7, sample preconcentration using pneumatic nebulization may be required to achieve lower
   detection limits.

   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.

Environmental Samples
Supplement 1
   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.
