Albertsons wants to add an organic grocery chain to it's mega shopping basket.

According to Bloomberg and the Financial Times, Albertsons is considering taking over Whole Foods or merging with Sprouts. 

"Any business in today's market is for sale," said San Diego State University (SDSU) marketing professor Miro Copic.  

He said Whole Foods has been struggling, closing stores and experimenting with a smaller cheaper space named 365 by Whole Foods. Part of the problem is that more traditional grocery stores and discount chains have started carrying organic lables. On top of that, Amazon could be stealing away younger shoppers by adding online grocery sales.

"Whole Foods is trying to figure out who they are in this new era of really competitive pricing in the supermarket retail space," said Copic.

Neither Albertsons nor Whole Foods are commenting on the report.  

Copic said if Albertsons were to be successful in taking over Whole Foods, it is unlikely shoppers would see any significant difference at the store level.  But the equity and expertise from the supermarket giant might help future growth and profitability for Whole Foods.

Whatever happens, Copic says the future is ripe for changes.

"This is going to be the wild, wild west for the next five years," said Copic, "Big changes in the malls. There's gonna be big changes in the supermarkets."

District officials updated the San Diego Unified School District (SDUSD) Board Tuesday night on its lead sampling program for campus water.

According to Board documents, the City and the school district plan to test all schools on district property for potential lead in drinking water by mid-June.

With about 200 schools total to test, the district is about half-way through the process.

A slide in a Power Point presentation made to elected officials shows the district has submitted sampling plans to the city for 109 schools. Of that, 72 schools have already been tested. Twenty nine schools have lab results from the city that do not pose a concern to the district in terms of the safety and quality of the drinking water.

As schools test for lead in their drinking water, they are required by the state to fix problems if they discover lead in water at levels greater than 15 parts per billion (ppb).

So far, those levels or above have only been discovered in two school campuses in San Diego Unified.

The presentation included information about possible health resources for families, including "referrals to specific clinics that do blood testing for lead."A charter school on the Emerson campus, where high levels of lead were discovered, is also offering families a free mobile clinic for lead testing.

The cost to provide bottled drinking water and make plumbing upgrades at Emerson was about $12,000, according to the board documents.

San Diego Unified School District is publishing test results for each school here.

NBC 7 is mapping the schools and the results. Parents can view how the testing is going and click on each location for updates and links to test results.

In 2009, California’s health department, OEHHA, set the public health goal for lead in drinking water at 0.2 parts per billion.

The California Public Interest Research Group (CALPIRG) and the American Academy of Pediatrics maintain there is no safe level of lead in drinking water provided to children.

Lead poisoning in children can cause symptoms ranging from headaches and hearing or speech problems to learning and behavioral problems or damage to the brain and nervous system.

The potential for lead contamination in the water supply is greater in buildings built before 1986, according to health, water and city experts.

There are 447 schools across San Diego County built before 1986.

A San Diego man is facing multiple charges for attempting to lure an 11-year-old girl to sexually exploit her in San Diego, according to a complaint filed with the U.S. District Court in the Southern District of California.

Miguel Cervantes, 24, faces charges of sexual exploitation of children and the attempted enticement of a minor, according to unsealed court documents. He contacted the minor using a phone and computer in an effort to coerce the victim, according to court documents.

Cervantes first contacted the minor on March 16, when she began chatting with him online through a mobile application called "Candid," according to the unsealed documents. 

Soon after they began talking, Cervantes asked the girl how old she was. He quickly discovered she was a minor and lied about his age, telling the victim that he was 18 years old when he was really several years older. 

Cervantes allegedly continued to message the victim, with increasingly lewd conversations that eventually led to him to send her photos of his genitals. 

On March 21, the minor contacted Cervantes and told him she was moving away from San Diego. In response, Cervantes tried to persuade her into traveling to San Diego for a weekend to meet him in a motel, and then tried to persuade her into saving her allowance money to buy him a plane ticket to visit her and a motel room, according to court documents.

Later, he coerced her into exchanging lewd photos. Shortly after he allegedly asked her, "Are you really only 11 tho?"

When she replied that she was only 11, he warned the minor not to tell anyone about their interaction.

"If anyone finds out that we're doing this, I could go to prison," said Cervantes, according to court documents. "So I just want you to know that."

On Mar. 22, Cervantes asked the minor for her street address, then encouraged her to leave her house and meet him. At that point, the victim became scared but Cervantes continued to pressure her and demand nude photos, according to court documents.

A few days later, the victim's mother found the lewd conversations on her daughter's iPad and called police.

Detective Elliot Shaffer, a Chula Vista police officer assigned to the Internet Crimes Against Children Task Force (ICAC), investigated the case. Detective Shaffer located the Candid mobile app as part of the ICAC investigation.

Shaffer communicated with Cervantes while posing as the 11-year-old victim and made plans to meet with him at a nearby McDonald's restaurant, according to court documents.

Cervantes was arrested when he showed up at McDonalds.

After his arrest, Cervantes waived his Miranda rights and admitted to knowing that the victim was a minor, and that he sent her multiple photos of his genitals using the Candid app, according to court documents.

He also acknowledged that he would have sexually exploited the minor if possible, according to court documents.

The date of Cervantes' court appearance was not immediately available.

A group of middle school students in Chula Vista became sick after eating laced snacks, according to the school principal.

The incident occurred early Wednesday at Bonita Vista Middle School.

A spokesperson for the Sweetwater Union School District told NBC 7, some students who ate the snacks got sick to their stomach.

As a precaution, the school called ambulances because it was unclear what substance the gummy bears were laced with. Those students are okay.

About five to six students gave out laced gummy bears to others, the spokesperson said. 

District officials and Chula Vista police are investigating what was inside the gummy bears but they believe it was a common type of marijuana edible. 

The students are facing disciplinary action.

One parent told NBC 7, the scary part is not knowing what substances could potentially be inside certain types of food.

"It's like I told her, whatever you do, you get offered, nothing. Don't touch it. I don't want you to be one of those girls," parent Yvonne Alvarez said.

A man who bit a San Diego County Sheriff's deputy, "growling like a dog" in a hostile confrontation, faces two felony charges connected to the incident, according to the District Attorney's office. 

Casey Clason pleaded not guilty to two felony charges in connection with a fight with several Sheriff's deputies early Sunday morning. The Judge denied bail because of a previous felony arson conviction. 

The incident, caught on camera, unfolded at approximately 4 a.m. when Clason walked into a 7-Eleven on E. Vista Way and Vale Terrace in Vista, emptied a liter of Coke on his head, spiked the bottle to the ground and then walked out of the convenience store, Deputy DA Keith Watanabe said. 

The man was visibly distraught, deputies said, so the employees at the store called 911 for help. 

Deputies responded to the scene and found Clason in the parking lot of a nearby church, with his hands wrapped around a flag pole. 

Despite commands, Clason ignored the deputies and walked away. 

When the deputies tried to detain him, Clason became violent right away and tried to kick deputies while on his back, SDSO Captain Charles Cinnamo said. Deputies called for back up. 

The incident quickly escalated as both deputies tried to Tase the defendant, Watanabe said. 

Then a fight began, Watanabe said. Clason bit one of the deputy's legs and refused to let to, Watanabe said. 

Multiple deputies rushed to the scene, hitting Clason and striking with with flashlights until the deputy was able to escape Clason's jaws. 

"During this entire encounter the defendant had bitten down on a deputy sheriffs calf and was growling like an animal and refused to let go," Watanabe said. "The deputies did what they needed to do in order to protect themselves from this type of behavior from the defendant."

The deputy's pants were able to protect him from the full impact of Clason's bite, Watanabe said. 

Deputies initially suspected Clason was under the influence, but officials have not received a full toxicology report yet. 

If convicted, Clason could spend three years and eight months in prison. 

He will next appear in court on May 5 for a readiness. 

The investigation into this incident is ongoing. Anyone with information is asked to call the San Diego Sheriff's Department at (858) 565-5200.

A North Texas man is planning his wife's funeral, just 39 days after they were married.

Lana Canada was shot and killed Monday morning by a co-worker at a North Dallas office building.

"I'm having a hard time with it. They pulled the love of my life away from me in just an instant," Dennis Canada told NBC 5 from the Sulphur Springs home he shared with his wife.

Everything in the backyard of their home reminds Canada of Lana, including a rose garden they worked on together just two days before she was killed.

"That's hard for me to look at," Canada said.

Lana was a mother of eight – seven daughters and one son – and a grandmother of seven. Together they had a blended family and were the picture of wedded bliss.

"The greatest marriage. The greatest relationship I'd ever been in," Canada said.

He recalled kissing his wife goodbye Monday morning before she left for work. Lana was a supervisor at Dignity Team Health, a Texas-based provider of in-home Hospice Care.

Hours later, she was killed in a conference room by a disgruntled employee who Canada says was "pretty mad" about Lana recently being named a co-partner. The shooter, 60-year-old Matthew Kempf, then turned the gun on himself.

Canada said he received a text about the shooting from one of his wife's co-workers.

He rushed to the north Dallas office building with Lana's 16-year-old daughter.

"When the detectives came out and they told me that Lana did not make it," Canada said through tears. "My world had been taken from me." 

Lana's funeral will be held Friday afternoon in Alba, Texas.

An active duty Marine based in Camp Pendleton and a Marine veteran are calling for change in the system after the Military's nude photo scandal. 

Marisa Wyotek, 22, an aviation technician based in Camp Pendleton, attended press conference where high-profile attorney Gloria Allred and U.S. Marine veteran Erika Butner spoke about the latest developments in the nude photo scandal.

Wyotek and Butner had personal images posted without consent to a closed Facebook group with a following of over 30,000 male service members.

Users shared nude images of active duty female Marines, veterans and other women, some of which were taken without the victim's knowledge and shared without their consent. It is not known how many service members were involved or are under investigation.

Allred came to San Diego because Gen. Robert Neller, the Marine commandant, was scheduled to visit Camp Pendleton on Thursday. She and her clients are hoping to meet with him.

After the press conference, Wyotek said many woman may be afraid to come forward. 

"They are too terrified to come forward, the backlash that they will receive whether in person through their command or through social media, it's definitely scary," the local Marine said. "As someone who has spoken out and has received backlash I can understand their worry."

The photos, Butner said, prompted obscene and lurid descriptions of “all the unspeakable things they’d do to me."

Gen. Neller has admonished those Marines who took part in the FB group. Neller has said fewer than 10 women victims have come forward so far in the ever-widening investigation into nude photos of female service members that were posted online without their permission.

Gloria Allred wants to take things a step further.

She wants the way the military deals with these types of cases to change. At the press conference, she called for written consent of a woman, before her picture is posted by servicemen on these types of websites.

“Let's see the results and let's see how open they are to hearing from any victim who would like to meet with General Neller and would like to testify before the United States Congress," Allred said.

The Naval Criminal Investigative Service launched an investigation into the matter and is urging victims of the photo-sharing to come forward.

Party Animal has issued a nationwide recall of its Cocolicious dog food after lab tests of some products showed traces of the euthanasia drug pentobarbital.

According to the Food and Drug Administration, a retailer in Texas alerted Party Animal of the contamination after a customer presented two cans of dog food that tested positive for pentobarbital, a drug used for euthanasia mostly of dogs, cats, and horses.

The affected products include 13-ounce-cans of Cocolicious Beef & Turkey dog food (Lot #0136E15204 04) with a best by date of July 2019, and 13-ounce cans of Cocolicious Chicken & Beef dog food (Lot #0134E15 237 13) with a best by date August 2019. The company said the food had been manufactured and distributed in 2015.

Party Animal contacted two retailers that may have sold the customer the food and asked them to remove all remaining cans from these lots from shelves. Pet owners who have cans with the recalled lot numbers to throw them away or return them to the place of purchase for a full refund.

The company said there was one report of a pet who experienced discomfort, but there have been no deaths reported.

"The safety of pets is and always will be our first priority. We sincerely regret the reports of the discomfort experienced by the pet who consumed this food," the company said in a statement.

Reports of space aliens and UFOs have flooded the telephone lines at Immigration and Customs Enforcement's newly launched VOICE hotline, established Wednesday through an executive order, which aims to provide public information and resources to the victims of crimes committed by undocumented immigrants, NBC news reported.

The calls are part of a protest campaign started on Twitter by Alex McCoy, 28, who encouraged others online to call the hotline and report encounters with extraterrestrial beings.

"I thought this was a chance to push back on how Trump has demonized the immigrant community. [The idea] really took off," McCoy told NBC News.

ICE spokesperson Bryan Cox confirmed to NBC News that the office received alien-related prank calls. He said additional operators will be added if future data reveals long wait times.

A suspect wanted on a warrant fled into the San Diego River, armed with a knife and a spear, gave himself up after a short standoff with San Diego police (SDPD). 

The incident began at 12:51 p.m. Thursday near Interstate 8 and Morena Boulevard. The man is now in the portion of the San Diego River below there, in the West Mission Valley area. 

Police said the man, who has not been identified, is wanted on a warrant. 

As police approached him, he fled into the riverbed, armed with a knife and a spear, police said. 

The incident prompted a short standoff. 

More than an hour later, the man gave himself up to police, who could be seen pulling the man out of the water.

U.S. Immigration and Customs Enforcement employees conducted a search of a home in the Grant Hill area Thursday.

An NBC 7 news crews saw several federal officials collecting evidence at the home on Island Avenue beginning at 6 a.m.

The agents were with the Homeland Security Investigations division of ICE. It's the investigative arm of the Department of Homeland Security.

A man who lives in the home told NBC 7 that officials were looking for his friend in connection to drug activity.

HSI agents would not speak to NBC 7 on camera.

A DHS spokesperson said officers were conducting a criminal investigation and that any official information would come from the U.S. Attorney's Office.

Neighbors told us they have noticed a lot of suspicious activity connected to this home for years.

Chula Vista celebrated the opening of a new park that will use technology to get kids outside.

After two years of planning, the playground on Connoley Circle is open for children.

Mayor Mary Salas told NBC 7 there used to be a park in this spot 25 years ago but that park was torn down because the equipment and features were worn.

Since then, the community has been advocating for a new playground and park for this community.

"We have been waiting on this for a long time because we have a lot of kids around here," said Susana Juarez.

"It's about time," said Alberto Torres. "I know the families want to keep their kids around the corner, right here so we can keep an eye on them." 

The Park is also SMART -- which means parents can download an app for the kids to interact and play games using markers set up on the playground.

“Any new projects we have, we’re going to try and implement the best technology,” Salas said.

Other parks in the city are also expected to see new renovations this year after voters voted for Measure P.

A Hollywood man beat his wife to death with a pipe wrench while their four children were home after learning she was pregnant with another man's baby, police said.

Claude Sejour, 48, was arrested Wednesday on a charge of premeditated homicide in the killing of 40-year-old Marie Carmel Joseph, Hollywood Police said.

Authorities said an officer responded to the couple's home on the 5900 block of Thomas Street Wednesday night after Sejour called 911 and said he killed his wife and was waiting outside for police.

An officer found Sejour outside the home with blood on his hands and cheek, according to a police report. Sejour told the officer that his wife had called her boyfriend, put the phone on speaker and the boyfriend revealed she was carrying his child, the report said.

"I did it. I finished her and called the police and went outside. I'm not crazy," Sejour told the officer, according to the report.

Inside the home officers found Joseph's body. She had severe trauma to her face and head, police said. Sejour told investigators that he hit her with a pipe wrench during an altercation.

The couple's four children, who range in age from 17 to 4, were also inside the home. The children are staying with a family member, the report said.

Sejour was being held without bond Thursday, Broward jail records showed. Attorney information wasn't available.

Just hours before the Los Angeles Chargers franchise will make its first pick in the NFL Draft, labor dispute signs popped up in front of the Chargers team headquarters in San Diego.

Three large signs, each with the printed words, “Labor Dispute Coming Soon!” are on the sidewalk in front of Chargers Park on Murphy Canyon Road.

The people holding the signs are handing out flyers with the headline, “Shame on Dean A. Spanos.”

When asked by NBC7 what is the reason for the signs? Armando Nunez of the Southwest Regional  Council of Carpenters called it a public awareness campaign to let the public know what was going on with the building of the Chargers new training facility in Costa Mesa.

Nunez contends that Chargers Chairman Dean Spanos hired a “contractor that the Southwest Carpenters have a dispute with.”

The Pacific Building Group is the name of the contractor that Nunez claims is not meeting area labor standards.

According to Nunez the Pacific Building Group does not pay area standards that are consistent to San Diego or Costa Mesa.  Including not fully paying for the carpenter craft workers  health benefits and pension.

“The way that translates is that the contractor takes advantage of the worker for higher profits,” said Nunez.

Nunez said the Carpenters Local 1506 has reached out to the Charger in hopes of coming to an agreement, but have not heard back from the organization.

NBC 7 also reached out to the Chargers for comment. We received the following the statement from Bill Johnston, the Chargers Director of Public Relations.

Statement from the Chargers:

We understand that the carpenters’ union has objections to the general contractor that we have hired in Costa Mesa because the union objects to some of the sub-contractors that the general contractor sometimes uses. None of these subcontractors, however, were used on our project in Costa Mesa.

In addition, we had no way of knowing that this was an issue for the union. This is the first time we are hearing of any of this. Had we known about the issue beforehand, we would have worked to address it. We have always sought and maintained excellent relationships with labor in San Diego and, now, in Los Angeles.

Finally, the carpentry portion of our Costa Mesa project is virtually finished. However, we are willing to engage in a dialogue with the carpenters’ union to address any concerns going forward, and we've reached out to the union to demonstrate a willingness to open lines of communication, but so far have not heard back.

The Los Angeles Chargers new training facility is located at 3333 Susan Street in Costa Mesa.  The Chargers will continue to operate out of their San Diego facility through June, then transition to their new Orange County location.

The backers of a plan to remove traffic from the heart of Balboa Park have just lost their bid for attorneys’ fees from an opposition group.

That's the upshot of an appeal court ruling involving the $80 million Plaza de Panama project.

This legal marathon started five years ago when billionaire Irwin Jacobs' Plaza de Panama Committee proposed a controversial bypass roadway off the Cabrillo Bridge, leading eastward to a paid parkade close to Park Boulevard.

That plan approved by the city was challenged by the nonprofit Save our Heritage Organisation (SOHO), which won in Superior Court but later lost on appeal.

Jacobs' committee requested that SOHO pay its lawyers’ fees, about $100,000, but a trial judge refused to award them.

On Thursday, the 4th District State Court of Appeal in San Diego ruled that environmental groups that bring lawsuits in "the public interest" aren't on the hook for such payments.

While the City Council approved a new version of the Jacobs plan and nearly $50 million for infrastructure, the Plaza de Panama Committee and a coalition of other park interests groups will contribute $30 million, plus cost overruns.

SOHO has since filed another lawsuit to stop the project, and that case has been scheduled for trial in August.

SOHO's lawyer noted that the published appellate decision is "precedent-setting", meaning it can be cited as guidance for trial court judges in any similar attorney-fee cases going forward.

Said Bruce Coons, executive director of SOHO: “We put our faith in the courts to enforce environmental laws, and could not do so if our good faith actions might result in liability for developers’ attorney fees.”

The attorney for the family of James DiMaggio, the man killed by FBI sharpshooters after allegedly kidnapping teenager Hannah Anderson in 2013, will file an amended wrongful death claim in the case.

Attorney Keith Greer will file the amended $20 million claim in Federal Court in Idaho on Friday. The suit claims FBI agents used excessive and unjustified force in killing DiMaggio in Idaho after a 6-day manhunt.

“We have serious concern that they were waiting for an opportunity to kill him and not waiting for an opportunity to apprehend him,” said Greer.

DiMaggio’s sister has much stronger words.

“I believe that a kill squad went in and hunted my brother down like an animal and shot and killed him. I believe my brother was murdered,” said Lora DiMaggio Robinson.

DiMaggio was shot and killed by FBI sharpshooters on August 10, 2013. Investigators claim he fled to Idaho after allegedly kidnapping the then-16-year-old Anderson. Days earlier, the bodies of her mother and brother were found in DiMaggio’s burned down home in Boulevard, Calif., east of San Diego.

Federal and state prosecutors say agents acted reasonably when they shot and killed DiMaggio.

But attorney Greer says FBI drone surveillance video shows agents had ample time to apprehend DiMaggio.

“If we allow the enforcers, in this case, the hostage rescue team, to be the executioner and the judge and jury, the system falls apart. We can’t have the police coming in and shooting people because they think they’re bad people,” said Greer.

“We want the same thing I’ve wanted from the beginning. I want answers. I want the truth. I want to know what happened to my best friend,” said DiMaggio Robinson.

It’s not easy for Jackie Shiolington to get around. 

“She has breast cancer that has metastasized to her brain so that’s limiting her mobility,” Jackie’s husband Jeff Ant said. 

Jeff said he had a temporary parking pass so the family could use handicapped parking spaces. The pass expired on December 31st and on January 1st, the family went to Ikea in Mission Valley. 

“I figured it will be fine, it will only be expired for a couple of days,” Jackie said. 

Jackie said she had an appointment at the DMV scheduled for January 4th to get a permanent handicapped placard but that wasn't soon enough. 

“There was a ticket on the windshield,” Jackie said. 

The ticket correctly pointed out Jackie’s handicapped placard was expired. Jackie and Jeff challenged the ticket but said it had been denied due to the couple missing some paperwork that needed to be sent in. So they took it to the next level, they paid the fine and asked for an administrative appeal hearing. 

“I set aside work time so I could make sure to take her with me and bring the new hang tag,” Jeff said. 

The hearing was set for April 11th but the family said before they had their day in court, a letter arrived in the mail saying something the family never expected. 

“You didn’t appear at the hearing and we found that the ticket is valid and we’re going to uphold it,” Jeff said the letter read. 

The court date had been moved up 21 days but Jeff said he had not been notified of the change. 

“It kind of felt unfair, kind of felt like a bait and switch,” Jeff said. 

The couple contacted NBC 7 Responds and according to the city of San Diego, administrative changes in the parking appeals process had been made, leading to hearing dates being changed but without some notifications sent to motorists. 

“He did tell me that it showed in the system that there was no notification sent out,” Jeff said. 

Jeff and Jackie said they were told by officials their case had not been handled properly and the city would dismiss the ticket and refund the fine they already paid. 

In an email, Parking Program Manager for the city of San Diego Jonathan Carey told NBC 7 Responds, “The independent contractor at the time of this hearing attempted to reschedule the hearing date and time for Mr. Ant, however, the system failed to generate a new notice in error. The independent office was unaware that the notice was not generated and so his hearing was conducted in written, or declaration format. The Parking Administration Program has worked directly with Mr. Ant and has resolved this issue to his satisfaction."

During a crackdown, 37 documented gang members were charged with distributing methamphetamine and illegal guns in San Diego, according to the U.S. Attorney's office.

Twenty-two of the 37 suspects were arrested this week and the other individuals were already in custody.

The San Diego Police Department (SDPD) and Homeland Security Investigations Gangs & Weapons Group co-led the year-long investigation known as "Seeing Blue."

According to the U.S. Attorney's Office, the defendants are documented members or associates of gangs in San Diego.

Undercover agents were able to identify several gang members, leading to their arrests, including Soulidao Chounlaboudy, Ruben Contreras-Ramirez, and John Quarles.

Investigators said Quarles ran a network from Teralta Park in City Heights and distributed dozens of pounds of methamphetamine. He made tens of thousands of dollars selling the drugs.

In the span of two days, authorities served 10 search warrants and seized more than three pounds of methamphetamine, along with 17 firearms and more than $25,000 in drugs.

Chounlaboudy and Ramirez face several charges including consipiracy to distribute methamphetamine, and felony possession of a firearm and ammunition. 

Quarles faces conspiracy to distribute cocaine and faces up to 20 years in prison and a $1 million fine, if convicted.

“Gangs and drugs are infesting many of our neighborhoods and creating a violent culture that is unsafe for residents,” said Acting U.S. Attorney Alana W. Robinson, in a statement. “With today’s action, we are reclaiming these parks and streets for our families, our children and our communities.”

The Los Angeles Chargers chose wide receiver Mike Williams out of Clemson with the seventh overall selection in the 2017 NFL Draft.

Williams returned to the gridiron in 2016 after his career was nearly cut short. In the previous year’s season opener, he fractured his neck when he hit his helmet against the goal post on a touchdown catch.

After a lengthy recovery he was cleared for contact and finished the 2016 season with 98 catches for 1,361 receiving yards and 11 touchdowns, according to Clemson University Athletics.

Williams will join an offensive unit lead by Bolts quarterback Philip Rivers and strong veteran wideouts, including Tyrell Williams, Dontrelle Inman, Travis Benjamin, and Keenan Allen who is returning after suffering a season-ending knee injury in 2016.

The Chargers first-round pick will be introduced officially on Friday at a press conference held at the Stub Hub Center in Carson.

The City of San Diego knows a lot about the drinking water it delivers to your doorstep. It conducts hundreds of weekly tests throughout the city measuring its water for contaminants, chemicals and whether or not it is corrosive at different distances from city treatment plants.

But once that water leaves public water mains and enters your service lines to come through your faucet, public utility experts know very little about what’s in it.

Federal regulations only require the city to test 54 homes every three years for lead and copper. Because every household’s piping is different, it is very difficult to know where exposure to lead or other contaminants remains high inside a home.

“It is often said that ‘there are no lead pipes in California.’ What that really means is that there are no lead pipes that people know about,” said Professor Marc Edwards, a civil engineer and water expert with Virginia Tech.

Because the city documents no lead pipes in its distribution system, it is required to test a very minimal number of homes, and it must prioritize testing of homes built between 1982 and 1986, according to rules set by the federal Environmental Protection Agency. The logic is these homes are the “newest” ones that are likely to have lead solder before it was banned in 1986. Because solder is worst when it is “new,” theoretically, these homes would have the highest risk for having lead in water in homes.

“Now, when the law was written in 1990, that may have been true. Those houses were 5-years-old or so,” said Edwards. “Whether it is actually true or not now, no one really knows.”

In San Diego, the city tested homes for lead in water primarily in Del Mar, Scripps Ranch, Bay Park and Linda Vista in 2014. Areas where lead has been discovered in school water or where kids have shown elevated blood lead levels at higher rates, like Grant Hill, San Ysidro and Mountain View are barely tested or not tested at all.

NBC 7 Investigates made this map showing where the city conducted its 2014 lead and copper testing in homes.

The city declined to release exact addresses, but provided primary streets with the nearest cross streets for where it did the tests. 

During its last round of lead testing, only three homes had any detectable levels of lead in the water. A home in Old Town had the highest amount with 146 parts per billion, which is nearly 10 times the limit that alarms federal regulators. But, because more than 90 percent of the homes tested fell below that threshold, the City of San Diego’s water is in compliance with federal regulations for lead.

Lead is a dangerous neuro-toxin and its negative health impacts can be particularly damaging in young children. Health experts say there is no safe limit of lead in water.

The city does a lot of its required testing for lead in homes in Linda Vista. In fact, nine of the 54 tests it conducts every three years are in one condo complex.

Linda Vista resident Ed Thomas said people have had concerns with their water there and wishes the city did more than the required minimal testing.

“I think if they’ve already seen problems, they should increase testing,” Thomas said. “Cause everyone should be safe, right?”

A spokesman for the city’s public water utility said the city tests neighborhoods that have the highest risks for lead coming from taps, which are homes built between 1982 and 1986.

One of the reasons the city only has to test 54 homes is because it has no known lead service lines.

NBC 7 asked Linda Vista resident Thomas if that puts his mind at ease.

“I guess so, but you know what? If you test it, then you know for sure," he said.

San Diego reports no lead pipes, but it has a lot of pipes and water mains made of material listed as “unknown,” according to data and information with the city and SANDAG.

In 1984, the EPA conducted a survey of 153 public water systems across the country to determine the extent of the use of lead pipes. San Diego responded it could not offer any estimate of the number of lead service lines remaining in the city.

A 2008 article in the National Institute of Health estimated that because San Diego continued permitting the installation of lead service lines, it likely had a significant number remaining.
