Lead & Copper Tap Sampling Instructions
Lead and copper samples are to be collected after water
has been in contact with the customer's plumbing for a minimum of six
(6) hours. This means that no water can be used from the plumbing. Samples
must be collected from the cold water faucet at the kitchen or bathroom
sink. Other than the obvious water use appliances, this may require
shutting off automatic water using devices such as humidifiers, hot
water boilers for heating, ice makers, lawn sprinklers, and water softeners.
If a water softener is present a bypass line must be used or the softener
turned off and the line flushed before the water is allowed to sit for
six (6) hours. The samples are to be "first draw" which means
that no water can be wasted and the first water out of the faucet must
fill the sample bottle.
Lead/Copper Sample Sheet
The sample sheet is divided into three sections. The
top section is to be completed by the representative or the public water
supply. The center section is to be completed by the collector of the
lead/copper tap sample. The bottom section is to be completed by an
accredited laboratory that will receive the sample in good condition
and run the sample according to the appropriate method provided.
Completing the Sample Sheet
- The sample collector's name must be printed and
legible.
- The address of where the lead/copper sample was
collected must be printed and legible.
- For validity purposes, the sample collector or
the water supply official must sign in the area provided.
Collecting the Tap Sample
- After the water been standing in the pipes for
a minimum of six hours with no disturbance, select either a cold water
or bathroom sink faucet.
- Keeping in mind the "first draw", place
the open container directly under the tap and turn one the faucet,
fill to ½" below the shoulder of the bottle and replace
cap.
