<br />STANISLAUS RIVER WATER IS HERE
<br />The City of Tracy is committed to providing a safe reli-
<br />able and affordable water supply to meet the needs of
<br />the community today and in the future. The City has
<br />participated with the cities of Manteca, Lathrop, Esnlon
<br />and the South San Joaquin Irrigation District to bring high
<br />quality Siem water from the Stanisbus River. This wa-
<br />ter source has increased the reliability of the Qty water
<br />supplies by having a third source of supply and provide
<br />redundancy in treatment facilities by having a second
<br />water treatment plan[ Delivery of water began in Au-
<br />gust 2005 and now comprises more than one hag of the
<br />City's water supply.
<br />CROSS CONNECTION PROTECTION
<br />Backilow prevention assemblies are designed to allow
<br />water to flow into your home or office from the public
<br />water system but not slow water to flow in the reverse
<br />direction, creating effective cross correction protection.
<br />Reverse flow an carry untreatable pol namn, and con-
<br />taminants back to the public water system compromising
<br />the water quality for all customers. Backflow prevention
<br />assemblies are required w be tested annually to ensure
<br />they are effectively protecting the public water system. If
<br />y ur residence has an active well on the premises or
<br />your business has fire sprinklers and/or landscaping, you
<br />probably have a backflow prevention assembly. For
<br />questions regarding annual testing requirements, please
<br />cal (209) 831-4488.
<br />WATER SOURCE ASSESSMENT
<br />An assessment of the drinking water sources (or the City
<br />of Tncy's water system was completed in June 2001.
<br />The sources are considered most vulnerable to the fol-
<br />lowdng activities: airports (maintenance and fueling areas),
<br />gas stations (historic and current), mining activities
<br />(historic and current), and septic and waste landfill
<br />dumps (historic and current). You may request a copy of
<br />the assessment by contacting ban Wengrtn at (209) 831-
<br />6302.
<br />Six of the City's wells contain elevated levels of Boron.
<br />Boron is a naturally occuning. non-cardnogenic, unregu-
<br />lated contaminant.
