Dear Sir;
We have the following to report on the sample submitted to this Laboratory on June 7, 1999.
Sample Number: 44015
Mark: water sample collected 06/07/99 by John Dufford from l 06

All parameters analyzed are below Maximum Contamination Levels(MCL's)for potable water and meet the
drinking water standards established by the Conn. State Health Department. The sodium content is above the
recommended 28 mg/L limit for people on low salt diets. If there are any questions we would be pleased to
discuss them with you.
Very truly yours,

PHYSICAL PARAMETERS
ODOR; MCL = none, recommended < 2 - Scale 0 = none, 1 =
very faint, 2 = faint, 3 = distinct, 4 = decided.
5 = strong. Good well water should be free of odor.
TURBIDITY; MCL = none, recommended < 5 - A measure of
particles in the water, usually indicates iron.
PH; MCL = none, recommended 6.4 - 10.0 - pH ranges from
0 - 14. A pH of 7 is neutral, < 7 is acidic, > 7 is
basic. A pH less than 6.4 is considered acidic and
may be corrosive to piping.
COLOR; MCL none, recommended < 15 - High color usually
indicates the presence of iron.
INORGANIC PARAMETERS
NIRITE NITROGEN; MCL 1.0 mq/L - An intermediate breakdown .
product of organic matter. See nitrate comment.
NITRATE NITROGEN; MCL 10.0 mq/L - The final completely
oxidized stage of nitrogen. Levels above 10 are known
to be harmful to infants. Preqnant/nursinq mothers
and parents of infants should consult with a physican.
CHLORIDE; MCL 250 mo/L - The non-metallic portion of common
salt. Levels above 50 mq/L may indicate undesirably
high sodium levels and it also may appreciably
increase corrosion rates. Levels above 250 mq/L inpart
a salty taste noticeable to most people.
HARDNESS; MCL none - A measure of the total calcium and
magnesium in water. Waters over 100 mo/L are described
as hard and levels over 250 mq/L are considered very
hard. The effect of hardness is to increase the amount
of soap necessary to form suds with water. High levels
may also increase scaling on the inside of water pipes.
IRON; MCL none - Above 0.3 mq/L iron may cause staining to
laundry and fixtures. Iron is naturally occurring
water mineral due to the geology of the area.
MANGENESE; MCL none - Above 0.05 mq/L mangensp�:may cause
staining to laundry and fixtures. See iron comment
SULFATE; MCL none - A naturally occuring substance in
water, levels above 250 mq/L may inpart a bitter taste
and render a laxative effect.
SODIUM; MCL none - A notification level of 28 mq/L has been
established for people on low salt diets, high levels
may increase the corrosive effect.
ORGANIC CHEMICALS
VOLATILE ORGANIC CHEMICALS (VOC) - see report for a listing
of the individual chemical MCL. VOC's are a gas chro-
matographic scan of 58 compounds. This list was de-
termined by the Conneticut State Department of Health.
These compounds include some of the more commonly found
ground water contaminates.
