IRWD Professionals Assure Water Quality
In order to ensure that Irvine Ranch Water District meets or exceeds state and federal guidelines when it comes to delivering safe water to our customers, the dedicated six members of the Water Quality Monitoring team fan out into the community daily, conducting sampling at any of the 180 to 200 drinking water sampling sites. All water samples are tested in our state-certified Water Quality Laboratory.
“Our Water Quality Monitoring staff is made up of very dedicated professionals who care about the environment and quality of drinking water,” said Regulatory Compliance Manager Cindy Beck.
Results of potable water sampling are compiled in the annual Water Quality Report, which is sent out to customers and available on our website.
The sampling sites are located throughout the community. Quite possibly, you might have noticed these sampling cans and wondered what they were, or you might not have noticed them at all. They are designed to pleasantly blend in with the landscape.
“A typical day on Monday and Tuesday is set aside for sampling potable (drinking) water,” said IRWD Senior Scientist John Hayes.
Each sampling site chosen represents a portion of the IRWD service area, with accessibility and safety to the field crews in mind. Sampling cans are all painted the same color of light brown with a slight difference – potable water samplings cans have blue decals, while recycled water sampling cans have purple decals. Each can contains a lock that may only be opened by a member of the monitoring team.
Water from IRWD drinking water tank reservoirs and all of the IRWD drinking water wells are also sampled and tested weekly.
Non-Drinking Water Monitoring
In addition to potable water, samples are collected from the San Joaquin Marsh and 11 other Natural Treatment System sites, from Irvine Lake, recycled water reservoirs, and both of the District’s water recycling plants, as well as 26 recycled water distribution system sample sites.
Once a week, monitoring crews take samples from Irvine Lake, which is the source of raw water used primarily for crop irrigation in the IRWD service area. Water in Irvine Lake comes from Lake Matthews in Riverside County. Fine-meshed nets are used to monitor quagga mussel larvae. Quagga Mussels are an invasive species, which multiply at a rapid rate and can clog water delivery pipes. In addition, the lake is monitored for dissolved metals at different depths.
Protecting the Environment
The Water Quality Monitoring Team also plays a key role in IRWD environmental stewardship, with five members of the team overseeing certain responsibilities:
- Industrial waste – the IRWD service area has many industrial-related businesses. IRWD conducts pre-treatment inspections of businesses to ensure no industrial waste is dumped into the sewer system, which could cause upsets in the District’s two wastewater treatment plants.
- Underground storage tank program – IRWD has tanks that provide diesel and gasoline to operate the District’s extensive fleet. These tanks are inspected weekly to ensure there are no leaks.
- Above ground storage tanks containing petroleum-related chemicals at various sites are inventoried once a year and inspected once a week for leaks.
- Hazardous waste program – used motor oil and filters, anti-freeze and paint are stored until they are properly disposed of. The county conducts an annual inspection of the storage site.
- Universal waste – light tubes, circuit boards and batteries and any other “e-waste” is collected and properly disposed of.

Take Control of Your Controller – Step 5
![Controller 02[1]](/assets/images/News Bureau/controller_02[1].jpg)
For the past few months, Irvine Ranch Water District has given you steps one through four on how to take control of your irrigation controller.
Now it’s time to take advantage of the seasonal adjustment feature (also called the % Adjust or Watering Index feature) on your controller.
The watering index value is a percentage that will change throughout the year and is normally 100 percent for the summer when plant water demands are the highest. The idea is to schedule your controller for the summer schedule and then use the Watering Index adjustment feature to have your controller automatically de=crease run times.
For example, if a zone runs for six minutes in summer, the controller would automatically reduce the runtime to three minutes if in Marsh you adjusted the controller to 50 percent using the Watering Index adjustment feature.
To find out more about the Watering Index, how to use it, and receive automatic reminders, sign up for IRWD’s Control Your Controller newsletter by emailing aws@irwd.com.
IRWD to Host Cleanup Site at San Diego Creek
For the 12th year, Irvine Ranch Water District will host a cleanup site at San Diego Creek on September 15. The site is one of 23 such sites that span the foothills to the coast. IRWD joins forces with Trails 4All, which conceived the idea of Inner-Coastal Watershed Clean-Up Day in conjunction with Coastal Clean-Up Day 16 years ago.
“Over the past 15 years, nearly 28,000 volunteers have participated and in 2010, we passed the million pounds of trash and recyclable materials collected,” said James Meyers, Executive Director of Trails 4All. “We now cover nearly all of inland Orange County, much of the Coyote Creek Watershed along the Los Angeles and Orange County border and we continue to expand upwards along the greater Santa Ana River Watershed.”
While Coastal Clean-Up Day focuses on cleaning trash from the beach, Inner-Coastal Watershed Clean-Up Day concentrates on getting trash out of the tributaries before it hits the beach. Trash dropped on the street ends up in storm drains and eventually finds itself on the coastline.
IRWD’s site will be located off Michelson Drive on Riparian View, adjacent San Diego Creek and the San Joaquin Marsh. Please wear closed-toed flat shoes, hats, sunscreen and insect repellant. The entire family is invited to learn about environmental stewardship and students can receive community service hours for their participation.

IRWD: Always Prepared
Irvine Ranch Water District is committed to emergency preparedness and conducts annual drills and exercises for employees. IRWD’s 16-foot-long Emergency Response Trailer is equipped with everything needed for such a response, including orange cones, protective suits, self-contained breathing apparatus, rubber boots and gloves, two children’s wading pools used for decontamination, medical supp-lies, first aid kits, generators and medical monitoring equipment.
“When an emergency situation call for it, IRWD’s highly trained hazardous materials response team utilizes the Emergency Response Trailer to take immediate action,” said IRWD Safety and Security Manager Ken Erwin.
In addition, there are real-life events that put what staff has learned to the test. In October 2007, the Santiago Fire ravaged Orange County and kept IRWD crews across many departments working around the clock to keep the water flowing to firefighters. Crews were out close to the fire lines, installing generators, operating pumps and manually measuring reservoir depths in areas where power and phone lines were knocked out by the flames. Some crews manned hoses to help protect key water facilities. One of the IRWD pump houses in the Portola Hills area was destroyed.
In December 2012, torrential storms caused significant damage to Williams Canyon, washing out a road along with IRWD water mains that supply water service to canyon residents. Over several days, including Christmas, crews worked in the rain to provide access for equ9ipment and construct two water bypass lines to restore water to residents.
Practice does make perfect. IRWD follows the guidelines and procedures practiced in the statewide, six-hour Emergency Preparedness Drill of 2008, one of the largest such drills in the nation’s history in which IRWD participated. To keep our emergency preparedness training current and fresh in the minds of our response team members, IRWD annually participates in a similar, but smaller, emergency preparedness drill.
To help you be better prepared, IRWD encourages you to review our list of emergency preparedness frequently asked questions. While you are there, don’t forget to sign up for the codeRED Emergency Alert System.
