As water travels over the surface of the land or through the ground, it dissolves naturally occurring minerals and can pick up substances resulting from the presence of animals or from human activity. Contaminants that may be present in source water include: (1) Microbial contaminants, such as viruses and bacteria, which may come from sewage treatment plants, septic systems, agricultural livestock operations, and wildlife. (2) Inorganic contaminants, such as salts and metals, which can be naturally-occurring or result from urban stormwater runoff, industrial or domestic wastewater discharges, oil and gas production, mining, or farming. (3) Pesticides and herbicides, which may come from a variety of sources such as agriculture, urban stormwater runoff, and residential uses. (4) Organic chemical contaminants, including synthetic and volatile organic chemicals, which are byproducts of industrial processes and petroleum production, and can also come from gas stations, urban stormwater runoff, and septic systems. (5) Radioactive contaminants, which can be naturally-occurring or be the result of oil and gas production and mining activities. In order to ensure that tap water is safe to drink, EPA prescribes regulations which limit the amount of certain contaminants in water provided by public water systems.  Food and Drug Administration regulations establish limits for contaminants in bottled water which must provide the same protection for public health.</div> <bR> <div> Water from surface sources is treated to make it drinkable while groundwater may or may not have any treatment.</div> <bR> <div> All drinking water, including bottled drinking water, may reasonably be expected to contain at least small amounts of some contaminants.  The presence of contaminants does not necessarily indicate that water poses a health risk.  More information can be obtained by calling the Environmental Protection Agency's Safe Drinking Water Hotline (800-426-4791).</div> <bR> <div> <B>SOURCES AND TREATMENT OF YOUR DRINKING WATER</B></div> <div> Your drinking water is surface water obtained from the Maury River.  Treatment is provided at the water filtration plant located off of U. S. Route 60 west.  Treatment includes chemical addition, rapid mixing, flocculation, sedimentation, filtration, chlorination, corrosion control and fluoridation.</div> <bR> <div> The design capacity of this system is 4.0 mgd (limited by high service pumping capacity).</div> <bR> <div> <B>SOURCE WATER ASSESSMENTS</B></div> <div> A source water assessment for the Maury River Service Authority was completed by the VDH on May 24, 2002. This assessment determined that the town's water source, Maury River, may be susceptible to contamination because it is a surface water exposed to a wide array of contaminants at varying concentrations and changing hydrologic, hydraulic and atmospheric conditions that promote migration of contaminants from land use activities of concern within the assessment area. More specific information may be obtained by contacting the water system representative listed above. </div> <bR> <div> <B>QUALITY OF YOUR DRINKING WATER</B></div> <div> Your drinking water is routinely monitored according to Federal and State Regulations for a variety of contaminants.  The tables that follow show the results of our monitoring for the period of January 1<FONT SIZE="1" COLOR="#000000" FACE="Arial" >st</FONT> through December 31<FONT SIZE="1" COLOR="#000000" FACE="Arial" >st</FONT>,<B> </B>2011.</div> <bR> <div> <B>DEFINITIONS</B><FONT SIZE="2" COLOR="#000000" FACE="Arial" ><B> </B></FONT></div> <div> In the table and elsewhere in this report you will find many terms and abbreviations you might not be familiar with.  The following definitions are provided to help you better understand these terms:</div> <bR> <div> <I>Non-detects (ND) - </I>lab analysis indicates that the contaminant is not present.</div> <bR> <div> <I>Parts per million (ppm) or Milligrams per liter (mg/l)</I> - one part per million corresponds to one minute in two years or a single penny in $10,000.</div> <bR> <div> <I>Parts per billion (ppb) or Micrograms per liter</I> - one part per billion corresponds to one minute in 2,000 years, or a single penny in $10,000,000. </div> <bR> <div> <I>Parts per trillion (ppt) or Nanograms per liter (nanograms/l)</I> - one part per trillion corresponds to one minute in 2,000,000 years, or a single penny in $10,000,000,000.</div> <bR> <div> <I>Picocuries per liter (pCi/L)</I> - picocuries per liter is a measure of the radioactivity in water.</div> <bR> <div> <I>Nephelometric Turbidity Unit (NTU)</I> - nephelometric turbidity unit is a measure of the clarity of water.

Lead in drinking water is primarily from materials and components associated with service lines and home plumbing. We are responsible for providing high quality drinking water, but cannot control the variety of materials used in plumbing components. When your water has been sitting for several hours, you can minimize the potential for lead exposure by flushing your tap for 30 seconds to 2 minutes before using water for drinking or cooking. If you are concerned about lead in your water, you may wish to have your water tested. Information on lead in drinking water, testing methods, and steps you can tank to minimize exposure is available from the Safe Drinking Water Hotline or at <A HREF="http://www.epa.gov/safewater/lead/" TARGET="_top" TITLE="http://www.epa.gov/safewater/lead/"><U>Lead in Drinking Water  Safe water  Water  US EPA</U></A>.</div> <bR> <bR> <div> <B>WATER QUALITY RESULTS </B></div> <bR> <bR> <div> <TABLE BORDER="2" CELLPADDING="1" CELLSPACING="1" WIDTH="716" BORDERCOLORLIGHT="#C0C0C0" BORDERCOLORDARK="#808080" FRAME="BOX" RULES="ALL" HSPACE="0" VSPACE="0" > <tR> <tD VALIGN=TOP COLSPAN=7 HEIGHT= 14 WIDTH="694"><div> <B>Inorganic Contaminants</B></div> </tD> </tR> <tR> <tD VALIGN=TOP HEIGHT= 28 WIDTH="118"><div> Contaminant / Unit of Measurement</div> </tD> <tD VALIGN=TOP WIDTH="58"><div> MCLG</div> </tD> <tD VALIGN=TOP WIDTH="88"><div> MCL</div> </tD> <tD VALIGN=TOP WIDTH="130"><div> Level Found </div> </tD> <tD VALIGN=TOP WIDTH="64"><div> Violation</div> </tD> <tD VALIGN=TOP><NOBR><div> Date of Sample</div> </NOBR></tD> <tD VALIGN=TOP WIDTH="136"><div> Typical Source of Contamination</div> </tD> </tR> <tR> <tD VALIGN=TOP HEIGHT= 55 WIDTH="118"><div> Nitrate</div> <div> ppm</div> </tD> <tD VALIGN=TOP WIDTH="58"><div> 10</div> </tD> <tD VALIGN=TOP WIDTH="88"><div> 10</div> </tD> <tD VALIGN=TOP WIDTH="130"><div> 0.25</div> </tD> <tD VALIGN=TOP WIDTH="64"><div> No</div> </tD> <tD VALIGN=TOP WIDTH="82"><div> June 2011</div> </tD> <tD VALIGN=TOP WIDTH="136"><div> Runoff from fertilizer use;
