Overview

Randomized trial monitors water quality in Faisalabad, suggesting multivariate control charts enhance detection of contaminants.

Key Points

  • To evaluate the effectiveness of multivariate control charts in assessing water quality at treatment plants in Faisalabad, Pakistan.
  • Analyzed water quality variables including turbidity, nitrate, fluoride, arsenic, and iron residue.
  • Utilized three multivariate statistical process control techniques: Hotelling's T 2, MEWMA, and MCUSUM.
  • Conducted assessments across multiple sites in Faisalabad.
  • The MEWMA control chart effectively identified out-of-control signals more than the other methods.
  • Showed greater sensitivity in detecting deviations from water quality standards compared to Hotelling's T 2 and MCUSUM.
