Letter: Re: the July 13. article “Local Opinion: Groundwater law loophole provides $313 million subsidy to Copper World/ Rosemont mine”

What will be the true cost of the Copper World mine to the citizens of greater Tucson? Levels of dust containing particulate matter and toxic metals will decrease air quality causing breathing problems and asthma rates to climb. Homeowners and developers will see property values plummet as our beautiful scenery is replaced with tailings. Bikers, hikers, retirees, tourists and their dollars will go elsewhere. Air quality monitoring stations cost millions. How many will it require so we know when it is unsafe to be outside? Toxic metals such as lead, arsenic, mercury and cadmium are already in the soil from earlier mines. Testing and remediation is a costly affair. Who pays if water supplies become contaminated or depleted? Of course YOU do; the taxpayer. Lucky for us, in 44 years when it becomes a superfund site we will be off the hook. Our children and grandchildren will have to pay for it.
