Levels of lead in drinking water can be high enough to pose a potential health threat to very young children, primarily from the use of lead solder for indoor plumbing.
In February 1987, New Jersey banned lead solder for use in the installation or repair of drinking water plumbing systems.
However, because lead solder continued to be available for purchase in the state, New Jersey Department of Health staff sought to (i) determine the extent to which schools and day care centers were in compliance with the ban, and (ii) determine the effectiveness of a solder analysis test kit commonly used by plumbing inspectors in the field.
Samples of solder were collected from 53 day care centers and 37 schools known to have been constructed or renovated after the ban took effect.
Samples from 24% of those facilities constructed or renovated just after the lead ban (1987-1988) tested positive for lead content.
However, for those facilities constructed or renovated in later years (1989-1992), there was a decline in the percentage of samples that tested positive for lead content.
For this period of time, 13% of the samples tested positive for lead.
In total, more than 10% of facilities with new plumbing installed between 1987 and 1992 had solder samples that tested positive for lead.
A lead in solder test kit commonly used by inspectors proved to be an effective screening tool for the field. (...)
