The sources of the Bedford Water Company water supply are three wells.  Bedrock well # 1 is 2' south of the pump house, gravel pack well # 4 is 1,350' northeast of the pump house, and gravel pack well # 3 is located 49' east of the pump house.  Treatment consist of chlorine for disinfection, sodium hydroxide for pH adjustment, and phosphate addition for corrosion control.

Radon is a radioactive gas that you can't see, taste or smell.  It can move up through the ground and into a home through cracks and holes in the foundation.  Radon can also get into indoor air when released from tap water from showering, washing dishes, and other household activities.  It is a known human carcinogen.  Breathing radon can lead to lung cancer.  Drinking water containing radon may cause an increased risk of stomach cancer.  Presently EPA is reviewing a standard for radon in water.
Lead and Copper	Units	MCLG	AL	90th percentile sample value	# sites above AL	Year	Violation Yes/No	Typical Source of Contaminant
Lead	ppb	0	15	30	3 of 10	2006	YES	Corrosion of household plumbing system
Infants and young children are typically more vulnerable to lead in drinking water than the general population.  It is possible that lead levels at your home may be higher than at other homes in the community as a result of materials used in your home's plumbing.  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 two minutes before using tap water.  Additional information is available from the Safe Drinking Water Hotline (800-426-4791).  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 may years could develop kidney problems or high blood pressure.
