The dates shown above are the dates of the readings. The readings are taken daily, and information from such readings is posted on the first day thereafter. If on any reading day there are problems retrieving the data, the last reported readings will remain posted until such time as new readings are obtained. Due to factors such as equipment failure, sample contamination and human error, the information displayed above
