1999 Test Results Table

Inorganic Contaminants

          * Lead and copper samples were last taken in the third quarter of 1999.  In the past, Bistone Municipal Water Supply District monitored for lead and copper every three years.  In March of 2003, Bistone received a letter from the Texas Commission on Environmental Quality stating lead and copper samples should now be taken every nine years.  The next samples are scheduled for the summer of 2009.  This frequency is in accordance with the regulations. 

            Infants and children who drink water containing lead in excess of the action level could experience delays in their physical or mental development.  Children could show slight deficits in attention span and learning abilities.  Adults who drink this water over many years could develop kidney problems or high blood pressure.

            Samples were taken from five different locations.  None of our sample sites exceeded the action level for lead or copper.  However, if you are concerned about elevated lead levels in your home’s water, you may wish to have your water tested and flush your tap for 30 seconds to 2 minutes before using tap water.  Additional information is available from the Safe Drinking Water Hotline (1-800-426-4791).

            Lead in drinking water is rarely the sole cause of lead poisoning, but it can add to a person’s total lead exposure.  All potential sources of lead in the household should be identified and removed, replaced or reduced.
