Surface Water Microscopic Particulate Analysis (SMPA)

This method assesses water treatment plant efficacy by identifying, enumerating and comparing microbiota to the lowest taxonomic level possible in both raw and finished drinking water. SMPA follows USEPA procedures for Microscopic Particulate Analysis for Filtration Plant Optimization. CH Diagnostic reports an overall microorganism log removal for the water treatment plant after collating samples taken from raw and finished waters. SMPA is an excellent process control technique that can be used for optimization of a filtration plant by determining:

  • If individual filter beds are operating properly
  • Reproduction of organisms within a plant
  • Qualitative and quantitative overview of treatment plant performance
  • Seasonal variations

Analysis Request Form (pdf)

A Surface Microscopic Particulate Analysis (SMPA) can be modified to include Giardia and Cryptosporidium analysis from the same sample. This is useful in obtaining additional water quality information concerning a raw water source and a filtration system. Giardia and Cryptosporidium analyses are separate and are NOT included along with a SMPA UNLESS otherwise indicated on analysis request forms.
