Just last month, Los Angeles water officials sent a letter to Boeing warning that water leaving the lab had higher than allowed levels of dioxins, copper and strontium-90, a radioactive contaminant earlier found in 1993 in the soil just outside the lab's property line.
Laboratory calculations predicted each radioactive contaminant would tightly bind to the soil, allowing the pollutants to travel a few meters at most.
Testing for volatile organic compounds, pesticides, metals, nitrate, bacteria, and radioactive contaminants could exceed $500, says Lynda Knobeloch, a former toxicologist with the Wisconsin Department of Health Services who was not involved with the paper.

Landslides, flooding and the possible failure of containment barriers are also a concern at the Mailuu-Suu site, which houses a significant amount of residual radioactive contaminants.
Using the Chernobyl Nuclear Power Plant disaster in Ukraine as a case study, this volume describes the assessment of groundwater vulnerability and an improved methodology based on integration of the methods of hydrogeological zonation and modeling of anomalously fast migration of radioactive contaminants from the land surface toward groundwater, to aid in evaluating groundwater vulnerability and conducting risk assessments for groundwater contamination from diverse sources, as well as selecting optimal remediation methods for reducing threats from residual radioactivity.
Radioactivity can be dangerous, and we should be carefully monitoring the oceans after what is certainly the largest accidental release of radioactive contaminants to the oceans in history," Buesseler said, referring to the Fukushima disaster, the world's worst nuclear power plant accident since Chernobyl in 1986.
No one was underground at the Department of Energy Waste Isolation Pilot Plant near Carlsbad, in New Mexico's Southeast, when the alarm went off at 11:30 pm MST on Friday, and none of the 139 employees working above ground at the facility was exposed to radioactive contaminants, he said.
Sydney, Sept 15 ( ANI ): Japanese Prime Minister Shinzo Abe's recent speech declaring that radioactive contaminants from the crippled Fukushima nuclear plant are under control, reassuring the International Olympic Committee, has backfired at home.
Just hours before Tokyo was chosen to host the 2020 Olympics, Abe gave an emphatic speech declaring that radioactive contaminants from the leakage were "completely blocked" in waters inside the bay near the plant.
Summary: Dr Rashid Ahmed bin Fahd, Minister of Environment and Water, has issued a decree allowing the import of all kinds of food and fodder from 14 Japanese provinces but with the requirement that the shipments must have a certificate from the Japanese health authorities stating that they do not contain radioactive contaminants in excess of the allowable limit.
