A comprehensive assessment of drinking water quality in Kondopoga, Kareliya

Water issue adressed: Too dirty

The aim of study was to investigate the ground water from the five springs of Kondopoga and Prionezhsky districts for their drinking suitability? According to this aim was tried to answer some questions. The first was: Could the spring water substitute tap water and bottled water? And the second one: Could the test-object Ceriodaphnia affinis be used for bioassay tests of drinking water quality? 

This goal implied the following tasks:

  1. Conduct instrument organoleptic tests (color and turbidity), as well as physical and chemical analysis of water samples.
  2. Compare the results of physical and chemical analysis with the sanitary norms (MPLs) established for drinking water.
  3. Determine total microbial count (TMC), E. titer and index  in the water samples and compare these with the sanitary norms.
  4. Evaluate and compare the results of biological, physical and chemical tests.
  5. Analyze the changes in physical and chemical indicators associated with activity of affinis.
  6. Determine applicability of Ceriodaphnia affinis for biological tests in various chemical conditions.

objects: Ground water from the five selected springs, tap and bottled water (“Karelskaya Zhemchuzhina”), bioassay.

Hypotheses: (i) if the spring water has acceptable organoleptic properties, then it is suitable for drinking; (ii) Ceriodaphnia affinis bioassay can be used as biological test to indicate the differences in physical and chemical properties of drinking water.  

This is how I came up with the idea for this project:

Survey of Kondopoga residents showed that they preferred to drink spring water and bottled water, because it looked more transparent and odorless than tap water. However, one cannot measure water quality given its organoleptic properties. I decided to conduct a comprehensive assessment of quality of ground and drinking water
