Michigan Safe Drinking Water Act Lead and Copper Rule Testing Status LEAD AND COPPER RULE TESTING Michigan Safe Drinking Water Act 399 enacted in 1976 to protect the public health Amended in 2018 to add more stringent testing for lead

LEAD AND COPPER RULE TESTING
EGLE (formerly MDEQ) designated new tiers for
determining what homes to test
Now water for testing must come from buildings with
lead service lines or lead pipes before sampling at buildings with other service line or plumbing materials
Lead service lines are the pipes that carry water from
the City pipes into the home
Service lines can be made of plastic, copper, galvanized
metal or lead

LEAD AND COPPER RULE TESTING
There are 2,600 homes in HW There are 40 known homes with lead service
lines
Information is from original records when
homes were built and tapped into the water system
SLIDE 6
LEAD AND COPPER RULE TESTING
Prior rule required 5 homes be tested every
2 years
New rule requires 20 homes with lead
service lines be tested annually
T
esting protocol also changed so a 1st liter and 5th liter of water are collected
An action level of 15 parts per billion set

SLIDE 8
LEAD AND COPPER RULE TESTING
Any test that exceeds 15 ppb for lead is considered over
the action level
Action level will be 12 ppb effective 2025 Two homes of the 20 tested exceeded the action level The remaining homes had levels that ranged from
undetectable to 5.6 ppb
The action level is not a health based standard but triggers
a call to action
No homes exceeded the action level for copper Not a violation of the Safe Drinking Water Act
SLIDE 9
LEAD AND COPPER RULE TESTING Once notified by EGLE, City must do the following: Notify the property owner of test results within 30
days which has been completed
Send out a Public Advisory Conduct Public Education campaign T
est again in 6 months and double the number of testing sites
Start inventory of entire city to determine where
there are lead service lines by 1-1-20 and completed by 1-1-25

Next steps
Waiting for EGLE confirmation of test results and
instructions for Public Advisory and Public Education campaign
A whole-house filter has been installed at the 2 homes
by the DPW
City obtaining bids for replacement of the lead service
leads
City responsible for cost of replacement Must replace minimum of 7% of lead service lines per
year and all within 20 years

LEAD AND COPPER TESTING RULE
SLIDE 13
LEAD AND COPPER RULE TESTING Why do we care about lead? No level of lead in the blood is safe; lead is a potent
irreversible neurotoxin
Lifelong multigenerational impacts Health effects from acute and chronic exposures Biggest concern is young children and infants, who
absorb more lead than the average adult
Health effect in children include: impaired mental
development, IQ deficits, shorter attention spans, low birth weight
SLIDE 14
LEAD AND COPPER RULE TESTING
Lead can enter drinking water when comes
into contact with pipes, solder and fixtures that contain lead
Homes with lead service lines have an
increased risk of lead in drinking water
Check to see if the water service line is lead

LEAD AND COPPER RULE TESTING
Recommended actions to help reduce lead exposure Run your water for at least 5 minutes to flush water with
lead service lines; until water runs cold for non-lead service lines
Consider using a filter to reduce lead Michigan Department of Health recommends any
household with an infant, young child or pregnant woman use a certified lead filter
Use cold water for drinking, cooking or preparing baby
formula
Do not boil water as boiling will not reduce the amount of
lead in water
Clean your faucet aerator to remove trapped debris
