Oregon health officials, on Wednesday, released an interactive map of schools that have released their test results of lead levels in the water. The map also shows schools that have not released their results.

Fear over lead levels was triggered in Portland, Oregon's largest city, after lead in two public schools were found in unsafe levels in the sinks and drinking fountains. 

In the summer, Portland Public Schools tested water levels at every school after Rose City Park and Creston showed alleviated levels of lead. 

In the map, released this week, you can click on local schools to see their lead test results. Almost every Portland Public School submitted their test result. Several charter schools, however, have not. 

All schools in Grant and Morror county have submitted results, however, Hood River County have not. 

Some schools conducted tests recently after Portland and other districts found high levels of lead in drinking fountains and sinks. 

Schools have to submit their Healthy and Safe School Plans by January 2017. Some of the results submitted have also laid out steps to reduce lead levels to under the federal standard of 20 parts per billion, according to Jefferson Public Radio.

Portland Public Schools are providing bottled and dispensed water to school students in the academic year 2016-17, which is costing the city around $1 million, due to the alleviated lead levels. 

Lead poisoning can lead to abdominal pain, abdominal cramps, aggressive behaviour, constipation, sleep problems, headaches, irritability, loss of developmental skills in children, loss of appetite, fatigue, high blood pressure, numbness or tingling in the extremities, memory loss, anaemia and kidney dysfunction.
