Q. Do we have "hard" or "soft" water?
A. The simple definition of water hardness, is the amount of dissolved calcium and magnesium in the water. Hard water is high in dissolved minerals, largely calcium and magnesium. Our water hardness measures at around 38 ppm, which is considered "slightly-hard."
Q. Why are Cross-Connection control and Back-flow prevention important? And am I at risk?
A. Back-flow takes place when water in a distribution system flows in the opposite direction from what is normal. This can be caused by higher pressure in the consumer’s piping (back-pressure) or reduced pressure in the City’s mains (back-siphonage). Back-flow can take place within any water distribution system whether it is private or public. Back-flow conditions would not normally pose problems without cross-connections. Cross-connections occur in locations where the water supply is connected to some appliance, equipment, or apparatus which acts as a source for pollution or contamination. If there is any way for contaminated water or other harmful substances to get back into the distribution system by way of back-pressure or back-siphonage, then it is a cross-connection.

Q. Is lead a problem in my drinking water?
A. The District is required to monitor on a annual basis for lead and copper. All customers that are chosen to sample for the District will receive a free water bill for the sampling month and this document containing the sampling results.
Lead in drinking water is an important health issue because of its potential toxic effects. Although, lead does not occur naturally in the SBCUD’s water supply, nor is it a result of the treatment or distribution processes at our plant. In our area, lead in drinking water is most commonly caused by lead-based solder used to join copper piping in home plumbing systems. When water stands for several hours in plumbing that contains lead, the metal can dissolve or leach into the water. Tennessee banned the use of solders containing lead in 1988, so only homes built before the ban are potentially affected. As a precaution, you can eliminate lead from your drinking water by allowing the water to run for a few minutes before consuming it.
