The purpose of the lead and copper tap sampling rule (LCR) is to protect public health by minimizing lead (Pb) and copper (Cu) levels
in drinking water. Lead and copper primarily is introduced to drinking water through corrosivity of plumbing materials which
contain lead and copper.
-
40
CFR 141, Subpart I.
-
All community and non-transient non-community water systems are
subject to LCR monitoring requirements
-
All samples should be taken from interior taps of consumption.
-
A lead and copper tap sampling plan is required to be completed
and approved by the Department 30 days prior to sampling.
-
Plans should be reviewed before sampling and updated if changes
are necessary.
-
All sites sampled must be on the plan in order to accept the
results.
-
It is recommended to have 1.5 times more sample sites than
required in order to increase sampling flexibility.
-
Instead of using a set maximum contaminant level (MCL), the LCR
has established Action Levels (AL) of 0.015 mg/l for lead and 1.3
mg/l for copper. These action levels are based on 90th percentile
levels of tap water samples.
-
In addition, systems with populations exceeding 50,000 must
sample for Water Quality Parameters (WQP) each time lead and copper
sampling is conducted. Systems with a population less than 50,001
only have to sample water quality parameters when action levels are
exceeded or upon the request of the Department if the system is
providing corrosion control treatment.
-
WQPs work in conjunction with lead and copper sampling to ensure
that there are no problems in the distribution system that may be
causing exceedances at individual locations.

- New water systems must conduct two consecutive six month
monitoring periods before they will be eligible for reduced
monitoring.
-
Depending on past test results, your system may be
eligible for reduced monitoring on an annual or triennial basis.
-
If results exceed the 90th percentile levels, your system
may be required to conduct more frequent monitoring.
- Please see
Monitoring Schedules and Forms for your system’s specific
requirements.
- Systems should start sampling lead and copper in line with
the standardized monitoring framework (SMF) schedule. This change
will start appearing on the 2012 monitoring reminder schedules.
- Systems on six month monitoring must sample during
January-June and July-December each year.
- For January-June sampling, results are due to the
Department by July 10th.
-
For July-December sampling, results are due to the
Department by January 10th.

The table below lists the number of samples to be collected
and analyzed for each reporting period.
