What are those green boxes?

PWSD Green Water sampling Box
The green boxes, or sample stations, provide designated sampling sites to retrieve potable water samples at any time (24/7) versus sampling directly from homes or businesses. 

Currently, the PWSD laboratory staff sample sixty sites for one level of testing for Colorado Department of Public Health and Environment (CDPHE) drinking water compliance. 

All of these sites are from customer hose bibs. As the population increases, more sample sites are necessary to meet the regulation. Sample sites are chosen to be representative of the entire distribution system.
