The smaller tube contains a conductivity sensor to measure electrical conductance of the water, which is strongly influenced by dissolved solids and a temperature gauge.

If they are not removed they spread quickly and an outbreak in the water system breaks out. But most water treatment plants are able to effectively remove the pathogens from the water.

This can increase sedimentation and destroy the habitats of aquatic life. These particles allow pollutants to attach to them and stay in the water.]]> 2017-10-03 12:24:03 UTC https://padlet.com/n_laplante1/5la4wqzkuacz/wish/193374600 nataliemetz19 https://padlet.com/n_laplante1/5la4wqzkuacz/wish/193375193 The instrument used to measure turbidity is called a nephlometer. The units are NTU or Nephelometric Turbidity Units.  ]]> 2017-10-03 12:25:37 UTC https://padlet.com/n_laplante1/5la4wqzkuacz/wish/193375193 nataliemetz19 https://padlet.com/n_laplante1/5la4wqzkuacz/wish/193375943 Turbidity can be seen by the eye to determine whether its cloudy or opaque. The higher the intensity of light the higher the turbidity. ]]> 2017-10-03 12:27:39 UTC https://padlet.com/n_laplante1/5la4wqzkuacz/wish/193375943 t_webster1 https://padlet.com/n_laplante1/5la4wqzkuacz/wish/193376198 Not transparent, or cloudy, not able to see through
