Water Samples


Capital Regional District (CRD) owned and operated water supply systems sample results can be found at the following link: https://www.crd.bc.ca/service/drinking-water/drinking-water-quality

All water suppliers in British Columbia are required to monitor water that reaches consumers for total coliform bacteria and Escherichia coli (E.coli) regularly. The monitoring is one part of a comprehensive approach to safe drinking water.


 
 

Acceptable Sample Results
The following results are considered acceptable for drinking water.
  • E. Coli
    • No E. Coli detectable per 100 ml of each water sample.
  • Coliform
    • If only one sample is taken in a 30-day period:
    • No detectable Coliform per 100 ml of water
    • If more than one sample is taken in a 30-day period:
    • At least 90% of samples will have no detectable Coliform per 100 ml of water, and 
    • No sample has more than 10 total Coliform per 100ml of water

Interpreting Sample Reports
In VIHA, the results of drinking water sampling are reported using the following coding system.
  • GTR200 ~ Greater than 200 background colonies on membrane filter per 100 ml of sample.
  • LT0 ~ Less than
  • LT1 ~ Less than 1
  • LT11  ~ Less than 1.1
  • LT2 ~ Less than 2
  • LT22 ~ Less than 2.2
  • LT5 ~ Less than 5
  • LT10 ~ Less than 10
  • LT50 ~ Less than 50
  • LT100 ~ Less than 100
  • GRTR ~ Greater than
  • LT1000 ~ Less than 1000
  • LT10K ~ Less than 10000
  • LT100K ~ Less than 100000
  • GR200 ~ Greater than 200.5

  • GR23 ~ Greater than 23.0
  • ESTCT ~ Estimated Count
  • ESTHCD ~ High colony density on membrane prevented accurate coliform count.

  • OGCOL ~ Overgrown with coliform present.
  • OGECOL ~ Overgrown with E. coli present.
  • OVEREN ~ Overgrown with Enterococci present.
  • OGC ~ Result indicates confluent bacterial growth preventing accurate coliform determination. Re sample for MPN testing by indicating Previous Sample Overgrown.
  • PSESP ~ Pseudomonas aeruginosa detected by enzyme substrate method. This method is under evaluation and may be more sensitive.
  • NGPRI ~ No green pigment noted in lauryl tryptose broth cultures.
  • GRPI15 ~ Green pigment noted in 1/5 lauryl tryptose broth cultures, indicative of presence of Pseudomonas species.

  • GRPI35 ~ Green pigment noted in 3/5 lauryl tryptose broth cultures, indicative of presence of Pseudomonas species.
  • GRPI45 ~ Green pigment noted in 4/5 lauryl tryptose broth cultures, indicative of presence of Pseudomonas species.
  • GRPI55 ~ Green pigment noted in 5/5 lauryl tryptose broth cultures, indicative of presence of Pseudomonas species.
  • GRPI1 ~ Green pigment noted in 1/5 to 5/5 lauryl tryptose broth cultures, indicative of presence of Pseudomonas species.
  • GRPI2 ~ Green pigment noted in 2/5 to 5/5 lauryl tryptose broth cultures, indicative of presence of Pseudomonas species.
  • GRPI3 ~ Green pigment noted in 3/5 to 5/5 lauryl tryptose broth cultures, indicative of presence of Pseudomonas species.
  • GRPI4 ~ Green pigment noted in 4/5 to 5/5 lauryl tryptose broth cultures, indicative of presence of Pseudomonas species.
  • PRELIM ~ Preliminary report

  • SAREPF ~ Sample received partially frozen. Result may not be valid.
  • EMPTY ~ Sample bottle received empty.
  • QRWRT ~ Sample exceeded 30 hours from time of collection, results may not be valid. No written report will be issued and only a qualitative result will be reported by telephone when test is completed.

The Capital Regional District provides water to the communities of Central Saanich, North Saanich, Oak Bay, Saanich, Sidney, Victoria/Esquimalt, West Shore and Sooke. Their water results are available on the CRD website, under Monthly Bacteriological Reports at the following location https://www.crd.bc.ca/service/drinking-water/drinking-water-quality
