Haloacetic Acid Mixtures
For GC/ECD Analysis of Haloacetic
Acids in Water
✔ Meet requirements for US EPA Methods 552, 552.1 and 552.2.
✔ Prepared from purified neat reference materials for the highest quality.
✔ Lot-to-lot consistency ensures analytical reproducibility.
✔ Certificate of analysis available or data pack containing statistical QA
results for concentration and homogeneity, and a lot sheet with a
balance printout of each analyte.
Haloacetic acids and other disinfectant byproducts are formed during the chlorination of drinking water. The
US Environmental Protection Agency (EPA) has published Stage 1 Disinfectants and Disinfection
Byproducts Rule to regulate haloacetic acids at 60ppb on an annual average. This standard became effective
December 2001 for large surface water public systems. In December 2003, it will become effective for small
surface water and all ground water public water systems.
