Aid for Rural Drinking Water Systems and Sanitation Concerns to be Discussed in September 21 Public Meeting in Tubac

The United States Section of the International Boundary and Water Commission (USIBWC) has scheduled a public meeting of the Southeast Arizona Citizens Forum for Thursday, September 21 at 5:00 p.m. at the Tubac Community Center, 50 Bridge Road, Tubac, AZ. Agenda items will cover state legislation to help small rural drinking water systems and a timeline of events leading to the partial breach of a manhole in a Nogales, Arizona sewer pipeline. The purpose of the forum is to promote the exchange of information between the USIBWC and the community regarding Commission projects and related activities in Pima, Cochise, and Santa Cruz Counties.

Amanda Stone, Chief Policy and Legislative Affairs Officer, Arizona Department of Environmental Quality (ADEQ), is presenting on the significant bill amendment to House Bill 2094 – Small Water Systems Fund. Ms. Stone will share ADEQ’s new statutory authority to help small rural drinking water systems return to compliance with the Safe Drinking Water Act requirements by providing another source of grant funding to implement system repairs and upgrades. There are approximately 50 small drinking water systems (serving 10,000 or fewer people) delivering water that contains contaminants at levels exceeding safe drinking water standards today in Arizona.

In other business, Sherry Sass, President, Friends of the Santa Cruz River (FOSCR), will present a video, Flirting with Disaster. The video is an encapsulated warning message distributed earlier this year regarding a sewer pipe, known as the International Outfall Interceptor (IOI), located in the Nogales Wash. The FOSCR is campaigning for a permanent fix to the IOI so the waters of the Wash do not become contaminated in the future.

Mr. Wayne Belzer, Environmental Engineer, USIBWC, will provide information on the partial breach of the IOI’s manhole 89 in the Nogales Wash. On July 25, 2017, the manhole became dislodged after heavy rainfall, resulting in a partial breach of the IOI and release of sewage into the Wash. A temporary bypass system has been installed to contain the sewage leak until a permanent repair is put in place. The bypass system, proposed solutions, and status of repairs will be discussed during the presentation.

In addition, Mr. Belzer will talk about future plans to repair the entire IOI. His presentation will include the history of the IOI, the planned use of Cast in Place Pipe (CIPP) technology, the status of the design that’s underway for the rehabilitation of the IOI, and projected completion of the design.

A complete agenda follows. Members of the public who would like more information about the meeting may call 520-281-1832 or email lori.kuczmanski@ibwc.gov.

From the Arizona Game and Fish Department:

Endangered Gila topminnow to combat mosquitoes, West Nile and Zika in Pima County: Fish used to reduce West Nile, Zika virus threat

Posted May 26, 2017
(*This release is issued jointly with the U.S. Fish and Wildlife Service and Pima County.)

 

PHOENIX — Pima County will have a new ally in the battle against mosquito-borne diseases this summer: endangered Gila topminnow.

The Arizona Game and Fish Department (AZGFD) provided 500 of the native fish, which will be introduced into standing waters in urban county areas. The project is being done under the Department’s federal permits and an Endangered Species Act Habitat Conservation Plan between Pima County and the U.S. Fish and Wildlife Service. The three agencies are cooperatively spearheading this effort to reduce threats to public health in the county.

The project is part of an overall plan by Pima County Health Department, Pima County Sustainability and Conservation, the Phoenix Zoo and Arizona State University to use the federally endangered fish to target mosquito larvae and reduce the threat of mosquito-borne diseases, such as the West Nile and Zika viruses. This approach is also being considered for future deployment in Pinal County and hopefully other county governments around the state.

“This project is one of the first to use an endangered species for vector control of mosquitoes,” said Ross Timmons, AZGFD’s project coordinator. “Standing waters are prime breeding habitat for mosquitoes, and that can pose a serious public health threat to the community.”

In cooperation with AZGFD and the U.S. Fish and Wildlife Service, Pima County will establish a holding facility where Gila topminnows can be stocked and raised. The fish will then be placed into abandoned urban sources of water, such as swimming pools, fountains and backyard ponds within the counties.

“This partnership provides Pima County with a smart, conservation minded tool to help us prevent mosquitoes and the diseases they spread,” said Dr. Francisco Garcia, Deputy County Administrator and Chief Medical Officer for Pima County.
Research over the past 20 years shows that Gila topminnow are just as effective at targeting mosquito larvae as the use of the exotic mosquitofish, which is a non-native species. While mosquitofish have been used with some success in reducing disease-carrying mosquitoes, their use has unintended consequences for native fish and their ecosystems when they escape confinement.
“This is a terrific example of how native species may provide benefits to human health and welfare, while recovering endangered species,” said Doug Duncan, U.S. Fish and Wildlife Service fish biologist. “Giving our native Gila topminnow a leg-up against their mosquitofish competitors is a logical advance in their recovery while guarding against the spread of dangerous diseases.”
The Gila topminnow is a small, short-lived fish, with a general lifespan of less than a year. As their name suggests, topminnows spend the majority of their time close to the water’s surface feeding on plants, small crustaceans and small invertebrates, including mosquito larvae.

Historically, topminnow were the most abundant fish species in the Gila River basin from western New Mexico to southern and western Arizona. Over time, habitat loss and degradation brought the topminnow to the brink of extinction.

It was listed as a federally endangered species in 1967. Since then, AZGFD and its partners have worked to restore topminnow populations with the goal of delisting the fish.
