Bacteria at the Water Fountain: How San Diego Scientists Use E. Coli to Test for Toxins in Water

It’s not always easy to tell if the water you’re drinking is safe. Some ways to check include lab testing and filters. And soon it could include E. coli bacteria. San Diego scientists are developing a new bacteria-based water sensing technology.

At Edison Elementary School in City Heights on a December afternoon, excited school children are grabbing their favorite foods and drinks.

It is well known that what children consume here impacts their brains and bodies. From the teriyaki chicken to the drinking water at the nearby fountain.

New California Law Creates Pathway to Water Industry Jobs for Military Veterans

Legislation co-sponsored by the San Diego County Water Authority and the Otay Water District is intended to make it easier for military veterans to launch careers in the water industry.

After Lt. Jose Martinez retired from the U.S. Navy in 2007, he went from serving his country underwater to serving reliable, high quality water to a community. 

His experience aboard a nuclear submarine and on the management staff of Otay Water District shares a few commonalities. Both involve highly complex systems, which often operate away of the public eye, either underwater or underground. 

“People turn on the tap and out comes water,” said Martinez, General Manager for ACWA-member Otay Water District. “It seems rather simple, but it’s really complex. It’s fascinating to me.”

Water industry jobs for military vets

Martinez’s experience as a naval nuclear engineer focused on submarines’ nuclear and non-nuclear systems, including water treatment. This gave him an advantage to transition to a civilian career in water.

A bill and new law, signed by Gov. Gavin Newsom in October 2019, sets the stage for making it much easier for military veterans to transition into the water industry. AB 1588, initiated by Martinez and Otay, intends to update the current water and wastewater certification system by giving military veterans credit for their experience and education that is applicable to the water industry. Essentially, veterans would not have to start at the bottom, but instead advance to testing that matches their level of experience. That way, veterans can enter the water workforce at a level that meets their paygrade.

‘Silver tsunami’ of retiring baby boomers creates opportunities

AB 1588 was introduced by Assemblymembers Todd Gloria (D-San Diego) and Adam Gray (D-Merced), and co-authored by several state legislators, including Assemblymember Tasha Boerner Horvath (D-Oceanside). The San Diego County Water Authority and Otay cosponsored the bill, with the goal of increasing the number of veterans entering the water industry to replace retiring baby boomers.

To address this challenge, the Water Authority and its 24 member agencies created a regional workforce development task force to address the oncoming ‘Silver Tsunami’ of retirees. The San Diego region alone employs approximately 4,500 water and wastewater workers, with more than 1,400 of those workers expected to reach retirement age by 2024, according to the Water Authority. Statewide, there are approximately 6,000 active certified wastewater treatment plant operators, and approximately 35,000 drinking water treatment and distribution operators. 

Jobs within the water industry often reflect military experience, and not necessarily ones directly related to water and wastewater treatment on a base or aboard a ship. Don Jones, with the Center for Water Studies at El Cajon’s Cuyamaca College, compared experience within a Combat Information Center on a warship to operating a SCADA system at a water facility, pointing out that experienced SCADA operators can be hard to find.

“It doesn’t matter if you’re opening a pump or firing a missile, the process is very similar, it’s the mechanical and electronic interface that matters. You’re electronically activating a piece of mechanical equipment,” Jones said. 

‘It’s all about serving people’

The water industry can also offer veterans a few other advantages. Shannon Cotulla served in the U.S. Army as a combat engineer between 1987 and 1992. After leaving the service, he contemplated aviation engineering, but a desire to work outdoors in civil engineering led him to the water industry. Today, Cotulla is Assistant General Manager at the South Tahoe Public Utility District and former member of ACWA’s Board of Directors. 

“The work is really meaningful, it’s all about serving people and keeping our communities safe,” Cotulla said. “There’s also security in knowing that your organization has rules and standards that you can look up to and isn’t subject to the whims that you sometimes find in the private sector.”

Otay’s Martinez said that it could take a few years for the state to make the changes called for in AB 1588. Nevertheless, the process is underway and includes having a veteran with water industry experience serve on a regulatory advisory board along with water industry members. In the meantime, news about the bill’s potential for veterans is raising awareness among veterans about why careers in the water industry represent a great opportunity.

“We really want to open up this talent pool,” Martinez said. “Veterans are the right candidates to fill these jobs because of the skilled work they’ve already demonstrated in their careers and their time in the military.”

Design a Native Garden

If you haven’t finished planting your sustainable garden yet this year, you still have some time. Choose native plants that will thrive in the arid San Diego County climate.

Native plants are naturally drought-tolerant. They also support local ecosystems by providing food and habitat for pollinators, such as butterflies and hummingbirds. Native plants can fall into one of many categories: trees, succulents, perennials, shrubs, grasses, groundcovers and more.

Create your sustainable garden

Each type of plant serves a different purpose in a sustainable garden.

Trees are a great way to provide natural shade. They also catch water that runs off your roof when it rains.

Perennials often have colorful flowers that bring beautiful colors for your garden.

Groundcovers and shrubs are great for covering dry slopes and catching rainwater.

Succulents look great next to rocks or other features in your garden and are usually low-maintenance.

Need ideas for your new sustainable garden this spring?

The California Native Plant Society-San Diego Chapter will conduct its eighth annual Garden Tour, The Artful California Native Garden: Native Gardens and Art Tour of East County on Saturday, April 4, from 9 a.m. to 4 p.m.

Vactor Truck-Leucadia Wastewater District-

Water Agencies Team Up to Reduce Potable Water Use

The Olivenhain Municipal Water District and Leucadia Wastewater District are reducing potable water use by switching to recycled water to flush sewer lines in their service areas.

With the recent installation of new equipment by both agencies, recycled water is now available to Leucadia for sewer line maintenance in the Village Park neighborhood in Encinitas and in the La Costa neighborhood in Carlsbad.

Regular flushing is important for gravity-fed sewer line maintenance. The process involves filling a specialized sewer cleaning vehicle, known as a vactor truck, with water and injecting the water into a sewer main. Flushing the pipes in proper working condition extends their lifetime by removing materials such as grease and roots, which can cause clogs and sewage overflows. Once flushed, a pipeline can be inspected and its condition assessed.

Recycled water, not potable water, now used to flush sewer lines

Prior to this project, Leucadia did not have access to recycled water in Olivenhain’s service area, instead filling vactor trucks with potable water. Leucadia identified the opportunity to reduce potable water use and save its ratepayers money, and approached Olivenhain about creating points at which the wastewater district could fill trucks with recycled water. Five locations throughout Encinitas and Carlsbad were selected.

“It’s a pleasure to partner with neighboring agencies for the common good,” said Olivenhain Municipal Water District Board President Ed Sprague stated. “Simple changes such as these add up and help ensure a reliable water supply for future generations.”

Regional partnership conserves drinking water

“Leucadia is excited to continue its regional partnership with the Olivenhain Municipal Water District,” said David Kulchin, Leucadia’s board president. “Using recycled water to clean sewer pipelines not only saves precious potable water supplies but continues our efforts to utilize renewable resources to the maximum extent possible.”

In addition to sewer line flushing, municipal street sweeping vehicles that were previously using potable water will be able to access recycled water thanks to the new connections. In accordance with state regulations governing recycled water use, the vactor trucks and street sweeping vehicles will have separate filling systems for potable and recycled water.

Approximately 14% of Olivenhain’s overall water demand is met with recycled water. Olivenhain produces up to two million gallons per day of recycled water at its 4S Ranch Water Reclamation Facility and supplements additional demand with recycled water purchased from Rancho Santa Fe Community Services District, City of San Diego, Vallecitos Water District, and San Elijo Joint Powers Authority.

“It might be formula, but it’s also tap water! Keeping baby healthy!” wrote Alisha Woodman, who won for the most “likes.”

One photo captured the use of water preparing for a holiday meal. Many people submitted wildlife and landscape photos. And, of course, there were selfies. Though the entry image choices varied, all depicted a precious resource — water — needed during the holiday season and year-round.

The second contest in December asked participants to submit photos with the theme “Drink Tap December.”  The focus was the importance of drinking safe and reliable tap water. Entries included a photo of the ocean beneath a pier, representing how tap water helps keep the ocean plastic-free; a toddler enjoying a bottle of milk made with water from the tap; and a photo from a demonstration in Tanzania on the difference between clean and unclean water.

“A moment that truly touched my heart. Seeing the difference between clean and unclean tap water, making a clay pot that will filter tap water and getting to meet the Masai family who will benefit from my gift that prevents typhoid and water borne diseases. We are fortunate to live in a country that has clean water. Only half of Tanzania’s 22 million people have access to clean drinking water,” said winner Margaret Meyer of Chula Vista.
