Turbidity readings are very high as previous few days have been very windy and the waves have stired up sediments.

still questioning EC units of measurement.

Comments from B1 apply to B5: Units for EC seem to be very low. Need to check the Hach as units of measurement may have changed given we had to calibrate the meter.
