No. The district did not test any outdoor hose bibs, nor did we test any school garden soil or produce. However, we are considering whether to test outdoor hose bibs that could be regularly used for irrigating vegetable gardens or drinking. In the meantime, we are encouraged by this memo from the Oregon Health Authority, which says that garden vegetables are not a significant source of lead, even when grown in contaminated soils.
Based on this advice, Portland Public Schools has decided to allow continued consumption of their school garden produce. We have not restricted the consumption of vegetables grown in our school gardens.
