Ballooning bromide concentrations

Ballooning bromide concentrations in rivers where Marcellus Shale wastewater discharges are on the rise, is another big worry to our public water suppliers. Elevated bromide levels create treatment problems which can result in the contamination of our drinking water with organic chemicals that cause cancer and birth defects. And what does the drilling industry say? Oh, it can't be the drilling wastewater--it must be the runoff from the road salt used! Meanwhile, the bromide levels spiked in the summer months when road salt isn't used, plus road salt has much more chloride and little bromide and the chloride level in the river water has not risen. Why does this industry deny their impact?
