San Diego Unified’s Lead Testing Results, Mapped
San Diego Unified has tested nearly 2,000 water fixtures for lead, after first finding contamination at a school in early 2017. Of those, nearly 20 fixtures tested above 15 parts per billion, the Environmental Protection Agency’s limit for lead content. The district has either fixed the problem or cut off access to those fixtures. Another 225 tested above 5 ppb — the standard for bottled water and the new target San Diego Unified has set for all of its water. Those, too, have been remediated or blocked off as the district finishes installing filters.
