Data by Year by Site by Parameter
Use this form to retrieve yearly summaries of hourly average data collected at some TREX continuous water monitoring stations. Although this is our most current data, it is not considered official until it has been certified by our technical staff. This information is updated hourly.This web page provides the most current hourly averaged data available. Our convention for time-tagging data is the beginning of each hour. For example, values shown for the noon hour are based on measurements take from noon to 1:00 p.m.. The noon average will not be calculated until after 1:00 p.m.. The noon average will be then be available on our external server after 1:30 p.m.. This results in an apparent one hour time lag in the data. We also present our data in Local Standard Time for each measuring site. During Daylight Savings, this introduces another apparent one hour time lag in the data.
