If you happened to use a restroom facility at Bartlett Lake, perhaps you are familiar with this array of signage aptly placed ABOVE the water fountain. KEEP YOUR WATERS CLEAN. Just remember from watershed to your kitchen sink, your water is connected.
"One of SRP's most important water management programs is water quality monitoring. It provides information about patterns and trends in SRP surface and groundwater quality and also about potential pollution sources. SRP monitors the rivers within the watershed, as well as the canals and groundwater wells within its water service area."
