(Portland, OR)  --  Portland Parks and Rec officials have a lot of work to do after high lead levels were uncovered at the Maltnomah Arts Center.  A recent review found drinking fountains at the center tested high for lead over the past several years.  FOX 12 says four of those fountains were still being used until recently.  Parks and Rec officials say there are no regulations that require water testing, but they're making changes.
