Call CTL at 1-(800)-962-5227 or
CTL Lab Service Representative and request a water testing kit.
Please let our Service Representative know if you are sending a sample from
your home, your business, or a state agency. There are different requirements
have a nitrate result greater than 10 ppm (mg/L). Is my water safe to drink? What
can I do to make my water safer to drink as far as nitrates are concerned?
The USEPA and the State of Wisconsin has set a Maximum Contamination
Level (MCL) of 10 ppm (mg/L) nitrate for public drinking water supplies and as
a guide for private water supplies. A MCL is the highest level of a contaminant
that is allowed in drinking water. Nitrates are dangerous especially to infants
under the age of 6 months. Some symptoms include shortness of breath and blue-baby
syndrome. Most adults are not overly affected by nitrates.
Care Specialist, Plumbers, and Well Installers are all good sources for treatment
systems for nitrates. There are several systems available to treat water for nitrates,
and these professionals will be able to suggest the best system for your needs.
have a white (or some other color) buildup around my sink drain and shower stall.
Is this coming from my water?
What you are most likely seeing is a build-up of hard water scale. Look in
your tea kettle and see if you find the same substance there. Hard water
scale is the result of water precipitating the natural calcium or magnesium compounds
from your water. Water that is hard is not a health threat, it is more an
esthetic issue. Some people prefer the taste of hard water to softer water.
The colors you may be seeing are the iron (reddish) or copper (greenish) also
precipitating out of your water. If you have your water tested for hardness
you can interpret the results as follows:
0 ppm Very Soft
50 ppm Soft
125 ppm Hard
200 White buildup will occur
250 Very Hard
How can I tell if
I have lead in my water?
public water supply is required to test for lead on a regular basis. You
can call them or ask for the latest issue of their Consumer Confidence Report
(this will list all the constituents the supplier must test for and whether or
not any contaminants were found). If you live in an older house, one which
may have lead pipes or lead based solder call our lab for specific instructions
and special sample bottles to have a sample analyzed.
- Non-Detects (ND) - laboratory analysis indicates
that the constituent is not found.
- Parts per million (ppm) or Milligrams
per liter (mg/l) - one part per million corresponds to one minute in two
years, or a single penny in $10,000.
- Parts per billion (ppb) or Micrograms
per liter - one part per billion corresponds to one minute in 2,000 years, or
a single penny in $10,000,000.
- Parts per trillion (ppt) or Nanograms
per liter (nanograms/l) - one part per trillion corresponds to one minute in 2,000,000
years, or a single penny in $10,000,000,000.
- Parts per quadrillion
(ppq) or Picograms per liter (picograms/l) - one part per quadrillion corresponds
to one minute in 2,000,000,000 years or one penny in $10,000,000,000,000.

if I need to send something that needs to remain frozen? How do I send it
to you? How would I pack it?
If you mail anything frozen, it is best
if you pack it in "dry ice" and send it next day service. This

although not all samples can be run on NIR. The other method of testing
is by Wet Chemistry. This method will take longer because of the drying
process and other testing procedures the Wet Chemistry method entails. Turn
