Escondido Employee Named California Laboratory Person of the Year

City of Escondido Water Quality Lab Associate Chemist Oyuna Jenkins has been named “Laboratory Person of the Year” by the California Water Environment Association for 2019-20.

Supervising Chemist Ralph Ginese nominated Jenkins for the award, calling her “an incredible asset” during her seven years working at the lab. “The lab technically could not function without Oyuna,” wrote Ginese.

“This is really teamwork,” said Oyuna Jenkins of her recognition. “I have to give credit to everyone in the lab. We work really hard. Whoever you call a hero, there are always people behind them.

“It’s all about public health. I feel like it’s making a difference, providing accurate information to the public as possible. It’s all coordination between distribution, collection, public works, and everyone involved.”

Escondido lab helps ensure safe, reliable water supply

Jenkins plays a key role in the lab’s safety processes, which ensures a safe, reliable water supply for City of Escondido customers. She runs metal analyses on drinking water, industrial waste, and every step of the wastewater treatment process. Jenkins also peforms required monthly and quarterly testing and cross-trains colleagues on testing procedures. In addition, she is the laboratory’s liaison to contract labs.

“She’s very analytical,” said Ginese. “She’s someone we can go to, brainstorm, and work together. She is not afraid when people question her data. She is secure in what she does.”

From Mongolia to Escondido

A native of Mongolia, Oyuna Jenkins earned her bachelor’s degree in chemistry from the Mongolian University of Science and Technology, which is among the top 15% of all programs worldwide. She immigrated to the United States in 1998. Jenkins continues to pursue advanced training. She first obtained CWEA certification in 2012 and completed the Water and Wastewater Certification program at Palomar College in 2016.

“Oyuna has worked tremendously hard to be where she is at today,” wrote Ginese in his award nomination. “She is grateful for the opportunity this country gives her and she shares that gratitude with those around her … She is what every supervisor/manager is looking for in a Laboratory Person of the Year Award.”

Escondido Water Quality Lab leads the way

Jenkins helped develop strategies to implement new techniques and processes supporting the implementation of strict new accreditation standards for California’s 600 certified water quality testing labs.

As reported earlier this year on Water News Network, the City of Escondido Water Quality Lab successfully adopted the anticipated regulations in advance of their formal implementation. Jenkins reviewed and wrote many of the lab’s new Standard Operating Procedures now being used. She also assisted in developing the facility’s annual goals, along with its new mission and value statements.

The ambitious approach to Environmental Lab Accreditation Program compliance under the more stringent quality control processes places Escondido in a leadership role as one of only two California labs already compliant with the new regulations.

Take a Test to Determine Your Soil Type

If you put a shovel into the ground in San Diego County, you are likely to encounter the region’s impermeable soil structure. Impermeable soils are defined by poor infiltration areas. This means water doesn’t flow through the soil to replenish groundwater, because the soil is too dense.

Having impermeable soil also means water does not soak evenly into the ground or flow through living soil to plants in a healthy way. No matter where you plan your landscape, you should concentrate on improving your soil structure. That will help you irrigate more efficiently and cost-effectively, and your plants will receive the nutrients and water they need to flourish. It is relatively easy to improve your soil structure, but first you need to determine what kind of soil you have.

Particle size matters

The three basic types of soil are:

Clay: Soil made up of the smallest particles
Silt: Soil made up of a mixture of particle sizes
Sand: Soil made up of the largest particles

In general, sandy soils drain faster than clay soils, because there is more space between the larger particles. Soil structure also influences the quality of the soil. Lifeless, compacted, sandy soil will not absorb water, while healthy clay soil will be more sponge-like, holding and releasing water. The “best” soil – an even blend of sand, silt and clay – is called loam.

Find your soil structure by testing your soil

Some tests can be done onsite to figure out what kind of soil you have. Others might require lab analysis. Certain other conditions require specialized tests, such as soil used for food production or soil receiving a lot of storm water.

You can test your home landscaping soil yourself using a “Jar Test.” This is a fun project to do with kids or as a family.

How to do the “Jar Test”

  • Use a one-quart glass container.
  • Add one cup of soil from the garden. You can select one area or take samples from several areas and blend them together.
  • Add three cups of distilled water.
  • Close the jar and shake it until all the soil solids are suspended in water. Put the jar on a shelf and wait 24 hours.
  • If the container is still cloudy, wait another 24 hours. After 48 hours, the soil layers should be settled on the bottom.
  • Measure the layers in proportion to each other, with the total adding up to 100%. Sand will be on the bottom, silt in the middle, and clay on top.
  • Refer to the graphic to determine your soil type, based on the proportions of sand, silt, and clay. Which jar does your home sample look most like?

Now you can work to improve your soil condition, providing the best possible foundation for your landscaping plants and the most efficient irrigation.

Cash Rebates Increase for Grass Removal in San Diego Region

April 8, 2019

Removing grass can generate rebates of at least $2 per square foot for San Diego residents under new enhanced incentives that started this month.

As of April 1, the Metropolitan Water District is offering $2 per square foot for every square foot of grass removed from yards and replaced with sustainable landscaping.

“San Diego County homeowners and businesses know that sustainable landscapes are key to water reliability in our region,” said Joni German, who manages the Water Authority’s WaterSmart Landscape Makeover Program. “With the help of local landscape architects and designers, our WaterSmart Landscape Makeover Program gives them the knowledge and skills they need to be successful. WaterSmart landscapes are an upgrade, not a compromise.”

Infrastructure

The San Diego County Water Authority sustains a $245 billion regional economy and the quality of life for 3.3 million residents through a multi-decade water supply diversification plan, major infrastructure investments and forward-thinking policies that promote fiscal and environmental responsibility.

California officials toured some of that infrastructure in July as they worked to prepare a water resilience portfolio for the state. Our reporting on the July 18 water portfolio tour was the third most read story of 2019 on the Water News Network.

Prepare Your Landscape for the First Rain

After a dry spell, the first rainfall is the most important water to capture for your landscape. This is called the “first flush.”

In arid regions like San Diego County, this happens every year because there is a long stretch of dry weather in between rainy seasons.

Why is the first rainfall so important?

It washes away pollutants that have collected since the last rain. This water needs to be filtered as much as possible by landscaping before it goes anywhere else. Usually the next stop for this water is storm drains that empty into oceans. So your landscape can be a very important tool in preventing the buildup of pollutants in local water supplies.

In addition, the first rain in the fall is very important for your plants. New or established plants will want to grow deep roots in the fall and winter, and the additional water is essential. Capturing the rain with your landscape reduces the need for increasing irrigation.

How much water comes off your roof?

Measure the size of your roof to determine how much water will come off it. The shape of your roof doesn’t matter in this instance. The same amount of water falls on the roof whether it is sloped or flat. You can measure a sloped roof either using an aerial view or from the ground without worrying about the slope itself. Just measure the outside edges the same way you would if it was flat and calculate the square footage.

Flat roofs covering a building in one contiguous shape are easier to measure. Some roofs are more complicated. You can divide this type of roof into individual squares or triangles. Then, measure each one at a time and add the figures together for your total roof area.

Calculate your potential water capture

Once you know the total roof area, you can determine the amount of rainfall it generates in gallons, then use the following formula to convert square feet to gallons.

Formula: Rainfall in Inches x Total Square Feet x 0.62 = Gallons of Rainwater from the Roof

Here’s an example using a 1,000 square foot roof: 1 inch of rain x 1000 x 0.62 = 620 gallons.

Even in a dry climate, this rainfall adds up to a lot of water runoff. It’s easy to see how important it is to save as much of this water as possible in a landscape designed to be a sponge instead of a brick. Take the watershed approach to designing your landscape, and you can use the first flush of rain to your advantage.
