Honoring Professor Thomas Meixner by following his call to protect our water

I was shocked and heart-broken to hear that Professor Thomas Meixner was shot in his office at the U of A. This is such a great loss for our community. In addition to losing a respected professor and hydrologist, Tucson has lost a champion for our precious water. 

While I didn't know him well, I would see Thomas at the LID meetings where we would discuss the latest on green stormwater infrastructure. He patiently fielded questions from this amateur water advocate. He always made me feel like a colleague.  A few years back, I asked him for suggestions of water issues to bring to Rep. Ann Kirkpatrick during Sustainable Tucson's Environmental Advocacy meeting. By the next morning, he shot off the following information to me. I am so grateful to him for making these issues so easy to understand and present. 

The two actions he proposed to safeguard our water were to codify the Waters of the U.S. Rule into law and to overturn the 1872 Mining Law that defines hardrock mineral extraction as the "highest and best" use of public lands - tying the hands of federal and local governments when U.S. or foreign mining interests want to mine in our area, using or polluting much of our groundwater. 

A great way to honor Professor Meixner would be to continue his fight for water by reaching out to your Members of Congress and asking them to protect our water by supporting those two actions.

Here is our presentation:

At Thomas' recommendation, I went over the importance of the Cienega Watershed in Rep. Kirkpatrick’s district. Preserving this region was obviously one of his passions.

(Below is Thomas presenting on the topic with Mead Mier.) 

It is important to preserve the Cienega Watershed because it includes five of the rarest habitat types in the American Southwest:

• Cienegas (marshlands)
• Cottonwood-willow riparian forests
• Sacaton grasslands
• Mesquite bosques
• Semi-desert grasslands

Cienega Creek is one of the few remaining perennial streams in Arizona, providing:

• Critical habitat for wildlife (threatened & endangered species).

• Historically important ranching operations. 

• Important cultural/ archaeological resources.
• An attractive visitor destination, for its scenic landscapes, natural beauty, and cultural heritage.
• Water source for Tucson Metropolitan Area. It provides 20% of Tucson’s ground water.

Challenges: Dewatering of Cienega Creek and wetlands through development, mining, and climate change threatens endangered species. 

Waters of the US Rule

The 2015 Waters of the US Rule extended the Clean Water Act to protect tributaries that feed navigable rivers. All of these waterways are connected. If you aren’t protecting the streams, you aren't protecting the bigger rivers. 

This is the map I used to show how the water flows to Tucson.

The EPA and the Army Corps of Engineers are implementing Executive Order 13778 which directs federal agencies to rescind the Waters of the U.S. which included rivers that don't flow year around. Tucsonans rely on both surface water and groundwater derived by infiltration or runoff, as well as Colorado River water. History has shown that pollutants entering dry riverbeds can contaminate our drinking water. Changes in standards for the Clean Water Act would be particularly consequential in Arizona. While other states have the authority to protect the quality of streams not subject to the Clean Water Act's jurisdiction, Arizona does NOT. In Arizona, state legislation forbids state agencies from exceeding the federal regulatory framework.  Therefore, any reduction in scope of federal jurisdiction may have the effect of exempting certain areas from water quality protections at the state level.

- From Letter by C.H. Huckelberry.  Pima County Administrator.

EPA data showed that 94 percent of streams in Arizona were protected by the Waters of the U.S. rule.  These streams are small but they feed into the Gila and Santa Cruz rivers. 

If the protections of the Clean Water Act are reduced to perennial waters, the vast majority of Arizona's streams will have no water quality protections at all. Essentially pollution becomes legal unless the state steps in. The state means the Arizona Department of Environmental Quality - which advertises that it sped up the permitting process for businesses and reduced "burdensome" laws and regulations - 48 of them. 

The Waters of the US Rule affects most of Tucson’s rivers (because most are not perennial). For example, without the Waters of the US rule, there is little to stop the operators of the Rosemont mine from dumping tailings and other pollutants into Davidson Canyon where they eventually would make their way into Cienega Creek and Tucson’s water supply. 

The Waters of the U.S. rule needs to be codified into law rather than being an EPA rule that any acting president can change at will. 

Another needed protection is the overturning of the 1872 Mining Law that defines hardrock mineral extraction as the “highest and best” use of most public lands, tying the hands of federal and local governments when U.S. or foreign mining interests want to mine our public lands. 

The federal government treats mining as a right on public lands - one that trumps other uses. That means they allow mining even if it threatens special places such as Grand Canyon or pollutes important water sources such as the Colorado River. According to the U.S. Environmental Protection Agency hardrock mining is the number one polluter in the country and has contaminated the headwaters of 40 percent of our western watersheds. It allows mining interests to take hardrock minerals such as copper, gold, silver and uranium from our public lands without paying any royalties to the American taxpayer.  

The 1872 Mining Law, signed by President Ulysses S. Grant, was intended to promote settlement of the West.  Written during a time when mining was done with picks and shovels, the 1872 Mining Law does not address the problems created by modern day techniques which have the ability to remove entire mountains. The law does not address or prohibit environmental damage or threats to wildlife and watersheds. It does not provide for adequate reclamation. 

It is way past time that we reform this antiquated law and adequately protect national treasures - including the Grand Canyon - important watersheds, wildlife, and the other public assets. We need a law that requires agencies to deny approval of a mining operation if it will harm human health, wildlife habitat, water resources, or sensitive lands. It should eliminate patenting of land, provide royalties to the taxpayers, and include strong reclamation standards.

Natural Resources Committee Chair Rep. Raúl M. Grijalva has been sponsoring bills to repeal the 1872 Mining Law for years. Let's honor Professor Meixner's memory by finally getting these two important actions passed.

Trail would honor Meixner

A campaign is underway to build a new recreational trail between Patagonia and Sonoita dedicated to connecting people with the landscape around them, just like the man for whom it would be named.

The Tom Meixner trail would cross about 8 miles of hills and grassland along Arizona state Route 82 and tie into a larger trail network through an area that meant a lot to the University of Arizona hydrologist and professor.
