Lead & Copper Sampling at Residential Water Taps

Lead (ppb)

3/21/94

Action Level: 90% of homes tested must have lead levels less than 15.0 ppb. Although we had two samples that exceeded the MCL, at the 90% level, our range was <2.0 ppb to 8.0 ppb.
<2.0 ppb 17.0 ppb
Corrosion of household plumbing systems.
Copper (ppm)

3/21/94

Action level: 90% of homes tested must have copper levels less than 1.3 ppm.
