In 1979, the Ramat Hovav toxic waste facility was established in Wadi el-Na'am because the area was perceived as invulnerable to leakage. However, within a decade, cracks were found in the rock beneath Ramat Hovav. In 2004, the Israeli Ministry of Health released Ben Gurion University research findings describing the health problems in a 20 km vicinity of Ramat Hovav. The study, funded in large part by Ramat Hovav, found higher rates of cancer and mortality for the 350,000 people in the area. Prematurely released to the media by an unknown source, the preliminary study was publicly discredited; However, its final conclusions – that Bedouin and Jewish residents near Ramat Hovav are significantly more susceptible than the rest of the population to miscarriages, severe birth defects, and respiratory diseases – passed a peer review several months later.
