sample and a five minute flushed water sample from the kitchen tap. The lead levels in the first draw water tank sample contained the highest levels of lead of all the samples collected. After flushing at the water tank tap for five minutes, lead levels decreased.

not flushed. consequence
Therefore, it was concluded that the high lead of the plumbing, and not the ground water quality.
It should be reiterated that, regardless of its source, elevated lead levels are a serious health concern. Homeowners with elevated levels of lead, regardless of the source, should take immediate steps to remediate the situation, assuming treatment is not already in place. The PWTA only requires a raw or untreated sample for lead since this is an indication of the ground water quality. A homeowner may want to collect a first draw sample (no flushing) in order to determine if there may be any issues with lead in the home’s plumbing system.
