Drinking Water Lead & Copper Sampling Instructions
Thank you for helping to monitor for lead and copper In your-drinking water. it is important that-you
follow these instructions so that we may collect an accurate measurement of the lead and copper in
your drinking water. This sample is‘supposed to represent the water you would typically drink and.the
faucet from where you would drink the water. Call your water supply if you have any questions.
41. Select a faucet in the school that is commonly used for drinking. DO.NOT sample from a laundry
sink or a hose spigot.
2. The DAY PRIOR to collection, flush the COLD water for at least 5 minutes at the selected faucet.
Then let the water sit for at least 6 hours before you plan to collect the sample. If you have a single
handle faucet, turn it te the COLD side. DO NOT use this faucet again until it is sampled.
3. Wait at least 6 hours before collecting your sample. Collect the sample prior to occupancy the next
morning. Stagnation periods longer than 24 hours may not be representative of normal use.
4, Fill the sample bottle to the neck with the “first draw” of COLD water from the faucet that you
flushed at least 6 hours previous. .
5. Please answer the following questions:
a) Did you flush the water for at least 5 minutes and let it sit unused for 6 hours before you filled the
bottle? : (1 Yes [] No

Lead/Copper — General Information
Lead fs a common metal found throughout the environment in lead-based paint, air, soil,
household dust, food and water. It builds up in the body over many years and may result in
damage to the brain, red blood cells and kidneys. Lead enters. drinking water primarily as a
resuit of corrosion, or wearing away of materials containing lead in the water distribution system.
These materials include lead-based solder used to join copper pipes, brass and lead piping. The
concentration of lead in drinking water may be a function of numerous factors related to the
presence of lead, water chemistry, temperature, pH, system hydraulics, usage, etc., and can
vary over time. The presence of copper in drinking water fs also primarily a result of corrosion.
Acute exposure to copper can result in nausea and diarrhea. The US EPA has established an
action level for lead of 0.015 milligrams per liter (mg/l) and 1.3 milligrams per IIter (mg/l) for
copper. for public water supplies,
SAMPLING PROTOCOL
Obtain sample containers and analysis from a laboratory certified by the DEQ for
lead/copper analysis.
> Collect first draw samples. (Water has stood motionless in the piping for at least 6
hours.) Do not sample after weekends, holidays or extended periods of stagnation. Do
not flush the sample tap before sample collection.
> Collect samples where water is drawn primarily for drinking. Sample drinking fountains
or kitchen/break room faucets if they are used routinely to obtain water for consumption.
Do not sample from slop sinks, hose bibbs, etc. ones that represent the water
distribution system, i.e. one in each building wing or on each floor. Or, you can collect
more than.the minimum number of samples.

xxxEND_PAGE:deq27_b236_1088_1093_3
For large facilities collect at least one sample per building until you get the number of
samples required for the population served by the water supply (See Table).
(f you have a only a few buildings, split the samples among them as best you can
according to where the water is being consumed.
ff you have fewer drinking water fixtures than the chart requires, sample the ones you
have and note on the sample log sheet you have sampled all drinking water fixtures.
Properly identify the sample location on the.lab slip and include the water supply serial
number (WSSN) on the lab sample forms to properly identify the samples, otherwise,
you may not be credited as having sampled.
> Be sure to request the proper lab analysis or test code for lead/copper and place the
forms with the bottles.
Refrigerate all samples during storage prior to shipment.
Deliver or mail the samples to the lab as soon as possible.
After 1 Receiving Lead/Copper Test Results
. Properly record sample results on DEQ sheet following the direction and send a copy to.
the local health department.
2. Calculate the 90" percentile using the directions on the record sheet, or request the LHD
do the calculations to determine the 90" percentile.
3. If you exceed an action level, you must:
« Notify the local health department within 24 hours or the next business day.
e Notify the public (consumers) of the lead. action level exceedance as instructed by
the health department and take steps to minimize exposure (shutting off fountain, or
flushing) as instructed.
* Additional actions such as sampling the source water for fead/copper and
investigating possible sources of lead in the distribution system should be discussed
with the local health department.
vvvwv
Vv
Within 6 months of the end of the monitoring period in which the action level was exceeded, the
facility will need to submit a proposal to conduct a “treatment study” or install “corrosion control
treatment.”
xxxEND_PAGE:deq27_b236_1088_1093_4
> Submit thé samples to the laboratory for
analysis, and record the results on the
sample recerd log provided by the MDEQ.
> Calculate the 90" percentile using the
directions on the log sheet, or submit your
sample results to the local health
department's noncommunity staff person for
calculating the 90" percentile,
> Whether or not you do the calculations of
the 90" percentile yourself, you are required
to submit the results to the local health
department noncommunity staff person.
Action levels of 0.015 mg/liter (ppm) far lead
and 1.3 mg/liter (ppm) for co; copper were
established in 1991. If the 90" percentile result
exceeds either level, the water supply is
required to initiate an investigation by:
Q Contacting the local health department for
further instructions
Q Sampling all other drinking water taps not
previously sampled
Sampling the. source water
Providing public education on the lead
exceedance to the population exposed. A
copper exceedance does not require public
notice at this time.
Q
Qa
Corrective measures for action level
exceedances may include replacement of
fixtures, piping or service lines. If the
contaminant level still cannot be reduced below
the action level through implementation-of these
measures, the water supply will need to conduct
a treatment study to investigate whether the
installation of corrosion control technology may
be necessary.

REQUIREMENTS
MICHIGAN DEPARTMENT .
OF ENVIRONMENTAL QUALITY
xxxEND_PAGE:deq27_b236_1088_1093_5
In 1974, out of concern for the quality of the
water we drink, Congress passed the Safe
Drinking Water Act. This Act gave the
U.S. Environmental Protection Agency (EPA)
responsibility for establishing and enforcing
drinking water quality standards nationwide.
The Michigan Safe Drinking Water Act (Act 399)
was enacted in 1976 and enables the Michigan
Department of Environmental Quality (MDEQ) to
maintain primacy (state authority) over the
drinking water program in our’ State. This Act
regulates both community and noncommunity
water supplies.
Noncommunity water supplies (NCWS) are of
two different types:
> A transient NCWS is one that serves water
to 25 or more different people each day for
at least 60 days out of the year. Examples
include restaurants, convenience stores,
campgrounds, etc.
> Anontransient NCWS serve the same 25
people each day for six months of the year,
such as a school, factory, office building,
etc.
The Safe Drinking Water Act contains language
regarding the requirements for nontransient,
NCWS’ built prior to 1987 to test for lead and
copper. The Federal lead and copper
regulations were revised in 1998. These
revisions went into effect on April 11, 2000,
requiring that ALL NCWS to test for lead and
copper. The rule changes have been
implemented in Michigan as part of the primacy
agreement. The sampling frequency is
established below in Table 1:

FREQUENTLY ASKED QUESTIONS
Why be concerned about lead or copper?
Lead is a common metal found throughout the
environment in lead-based paint, air, soil,
household dust, food and water. /t builds up in
the body over many years and may result in
damage to the brain, red blood cells and
kidneys. Lead enters drinking water primarily as
a result of corrosion, or wearing away of
materials containing lead in the water
distribution system, such as lead service lines
and lead solder. The presence of copper in
drinking water is also primarily a result of
corrosion. Acute exposure to copper can result
in nausea and diarrhea.
/ have never had to sample before. Why do!
have to now?
The revised rule requires that all of the
nontransient NCWS must test for lead and
copper. It has been shown that some fixtures,
even though they were labeled "lead-free" have
released small amounts of lead when exposed
to water with corrosive or acidic qualities.
Copper is still | commonly used in plumbing
fixtures and piping, and these water quality
factors may cause copper to be released into
the drinking water.
/ only have two drinking water fountains in my
building? Do | still have to take the required
number of samples?
If you have fewer drinking water fixtures than the
chart requires, sample the ones you have and
note on the sample log sheet you have sampled
all drinking water fixtures.
We operate a large facility with multiple buildings
and numerous drinking water fixtures, How
many and where to do we sample from?
Sample the drinking water fixtures in the building
up to the chart number based on the population
of your facility. For instance, if your building has
eight drinking water fixtures, and you are
required to take five samples, sample only five
of the fixtures. If you have more than the chart
number of drinking water fixtures, select ones
that represent the water distribution system, i.e.
one in each building wing or on each floor.
For large facilities colléct at least one sample
per building until you get the number of samples
required in Table 1. Or, you can collect more
than the minimum number of samples. If you
have only a few buildings, split the samples
among them as best you can according to where
the water is being consumed.
