TURBIDITY READINGS

***** Special Notice June 28, 2017 *****

The Boil Water Notice has been recinded and a Water Quality Advisory remains in effect for customers of the Ashcroft water supply system until further notice. 

The Village of Ashcroft sources our water from the Thompson River and we monitor the turbidity on a regular basis.  The turbidity is recorded at the River Pumphouse which is where the water is pumped from the river into the well, and then further into the system.  This turbidity reading is generally a higher number as the pumps continually stir up any sediment that may be in the system.

The turbidity level is also recorded at Pumphouse #2 which is where the water actually feeds into our water system.  This reading is the actual level of turbidity in the water that flows to each and every water service within our community.  This turbidity reading is generally considerably lower as the water is not distubed as often and there is more settlement of the particulate.
 
Interior Health has advised that the reading at Pumphouse #2 is the reading that will determine our Water Quality Level however we will continue to record both turbidity readings for your information and reference. 

For more information about water quality and how seriously this issue is taken by water operators like the Village of Ashcroft and Interior Health, we encourage you to visit this webpage developed by Interior Health.  Please be sure to watch the videos posted at the bottom of the page.
