"The FDA’s Derived Intervention Level—the standard observed for food—for a related isotope, Strontium-90, is 4,400 pCi/L. The EPA’s Maximum Contamination Level for Sr-89 in drinking water is 20 pCi/L. (For more on the difference between EPA and FDA standards, as well as more on the health implications of ingesting radionuclides, see “Why Does FDA Tolerate More Radiation Than EPA?“)"
EPA has found no strontium-90 in its testing, according to the statement, and it has found neither of the strontium fission products in drinking water.
The Strontium-89 was found in April 4 Hilo samples previously found to contain cesium-134 and cesium-137, and the test results were released only yesterday because they take longer to analyze, according to EPA’s statement:

In response to the Japanese nuclear power plant release, if we identify radioactive cesium… those samples will be analyzed for strontium. Testing for strontium is a complex process that takes time.
More cesium was found in a Hilo milk sample on April 13. All of EPA’s initial milk testing is available here.
