Ladera Ranch CA Drinking Water Source is Robert B. Diemer Water Treatment Plant Yorba Linda It Sits on Top of 2 Old Oil Wells

Ladera Ranch CA Drinking Water Source is Robert B. Diemer Water Treatment Plant in Yorba Linda CA, It Sits on Top of 2 Old Shell Oil Wells that were plugged and capped in the 1950's. Ladera Ranch, California gets its drinking water primarily from imported supplies provided by the Metropolitan Water District of Southern California (MWD) via the State Water Project's California Aqueduct and the Colorado River Aqueduct, alongside local sources managed by the Santa Margarita Water District. Robert B. Diemer Water Treatment Plant operated by the Metropolitan Water District of Southern California. Metropolitan Water District treatment facility is at 3972 Valley View Ave Yorba Linda CA.

The more I dig into the mystery of the multiple Ewing sarcoma cancer cases and the old Shell oil wells under Ladera Ranch CA and possible water contamination, the more bizarre it gets. Today I discover that the water source for Ladera Ranch, the Robert B. Diemer water treatment plant, was built in 1961 on top of two old Shell oil wells from 1954, both deep drilled to over 4,000 feet. The Robert B. Diemer Water Treatment Plant operated by the Metropolitan Water District of Southern California was built between 1961 and 1963, officially starting its operations in 1963. The two old Shell oil wells that are located on either side of the Robert B. Diemer Water Treatment Plant were capped and plugged in 1954, there does not appear to be another re-abandonment of the two old Shell oil wells done during construction of the Robert B. Diemer Water Treatment Plant in 1961, why?

Concern over Cancer and Old Oil & Gas Wells at Ladera Ranch CA Needs Focus on Sewer System Built on Top of Decaying Well 8,365ft Under Merriweather Pl right near Poets Park. The so called re-abondonment of the decades old oil well at/under Poets Park on July 19, 2001 during construction of the Ladera Ranch community is bogus. Paul Frost engineer and rep for DOGGR was at the Poets Park Ladera Ranch CA job site from 9:30 am to 10:30 am on Thursday July 19, 2001. Paul Frost called DOGGR home office in Sacramento CA at 10:30 am to get an ok to close the well by plugging the well from 351 feet up to the surface, as they could not get past an obstruction at 351', leaving the other 8,014 feet to the bottom open to the elements and most likely leaking.

Thomas M. Walker an independent petroleum consultant and senior reservoir engineer in California was working (paid) as the rep for DMB Ladera LLC and was overseeing the re-abandonment project (that was stuck at 351') of the old Exxon Mobil oil & gas well that was drilled down to 8,365' (in 1961) on Thursday morn July 19, 2001 near Poets Park, Walker was there with DOGGR rep/engineer Paul Frost. A DOGGR directive required cement to be squeezed past the blockage at 351 feet on outside of casing down to bottom of oil well to protect the lower 8,014 feet, it was not done according to site reports filed by Paul Frost rep for DOGGR at Poets Park Ladera Ranch CA. 

An old oil and gas well located underneath a community's sewer system can cause significant health and safety problems. The "Highway Effect" of Sewer Lines: Underground sewer pipes sit in trenches backfilled with loose, porous gravel and soil. If a deep oil well leaks gas upward, the gas will take the path of least resistance. It can penetrate cracked sewer pipes or travel horizontally along the loose soil surrounding the plumbing network, distributing toxins right into neighborhood properties. Old wells frequently leak benzene, hydrogen sulfide (H₂S), and other volatile organic compounds (VOCs).

If the steel casings of the decades old 1961 deep drilled  Exxon Mobil oil & gas well under Merriweather PL near Poets Park in Ladera Ranch CA has crumbled and released crude oil or methane/benzine gas into the sewer system there will be severe health problems. A 1960's era deep drilled oil & gas well is right under the SMWD sewer system at Poets Park, Ladera Ranch and there is a 1920's era deep drilled oil & gas well under the SMWD sewer line at Citrus Lane Ladera Ranch with notations to NOT build over this well. Crude oil intrusion into a sewer system can cause significant human health problems. 

Whether the entry occurs through a ruptured underground pipeline, an accidental industrial leak, or illegal dumping, mixing crude oil with wastewater infrastructure poses both immediate and long-term medical risks. Crude oil contains volatile organic compounds (VOCs) like benzene, toluene, and xylene. Because sewer systems connect directly to homes and businesses via plumbing vents and drains, these hazardous gases can travel up pipelines and enter indoor living spaces. Children, the elderly, and individuals with asthma or pre-existing respiratory conditions are highly susceptible. Chronic exposure to chemicals found in crude oil, specifically benzene, is known to cause leukemia and other cancers under California Proposition 65 guideline.

 

Sat July 25, 2026, This so called re-abondonment of the decades old oil well at/under Poets Park on July 19, 2001 is bogus. Paul Frost engineer and rep for DOGGR was at the Poets Park Ladera Ranch CA job site from 9:30 am to 10:30 am on Thursday July 19, 2001. Paul Frost called DOGGR home office in Sacramento CA at 10:30 am to get an ok to close the well by plugging the well from 351 feet up to the surface, as they could not get past an obstruction at 351', leaving the other 8,014 feet to the bottom open to the elements. "Evidence now, theories later" my independent investigation of rare cancer cluster in Ladera Ranch CA and two abandoned oil & gas wells deep drilled thousands of feet underground that I published today about 'not building over' the poorly re-capped wells in July 2001 by DMB Ladera LLC the developer of the $100 million dollar project.
