Water managers may be excited at the early promise of adequate water supplies for the coming summer.

Key Points: 
  • Water managers may be excited at the early promise of adequate water supplies for the coming summer.
  • It is the Sierra snowpack that replenishes a portion of California's water supply.
  • Drinking water contains the carcinogenic compounds known as Haloacetic Acids and Trihalomethanes.
  • If this happens in areas that supply consumers with drinking water , the level of trihalomethanes in water will be significantly higher in the spring and summer of 2022 than in past years," added McMahon.

SUNNYVALE, Calif., April 5, 2021 /PRNewswire/ --Municipal utility laboratories, contract testing laboratories, and local or regional governing agencies performing water testing can now benefit from a new, validated application workflow using ion chromatography tandem mass spectrometry (IC-MS/MS) to achieve haloacetic acid (HAA) analysis in drinking water in accordance with the U.S. Environmental Protection Agency Method 557 (EPA 557).

Key Points: 
  • SUNNYVALE, Calif., April 5, 2021 /PRNewswire/ --Municipal utility laboratories, contract testing laboratories, and local or regional governing agencies performing water testing can now benefit from a new, validated application workflow using ion chromatography tandem mass spectrometry (IC-MS/MS) to achieve haloacetic acid (HAA) analysis in drinking water in accordance with the U.S. Environmental Protection Agency Method 557 (EPA 557).
  • The robust and validated workflow enables method precision and accuracy, following the EPA 557 regulation, which is paramount to testing drinking water safety.
  • "The new IC-MS/MS workflow for HAA analysis in drinking water can determine all relevant analytes in water samples in 35 minutes, a 39% faster analysis time than the original U.S. EPA Method 557 workflow."
  • The validated IC-MS/MS workflow enables reliable and reproducible quantitation of target HAAs in drinking water per EPA method 557.
