Drinking water in California is so watery it could make a movie about it.

A study released Wednesday found California has among the highest levels of fluoride in the country.

“California is a state with a particularly high concentration of fluoride, and a disproportionate amount of that fluoride is in drinking water,” said the study, published in the journal Environmental Health Perspectives.

“In this study, we found that California residents in the San Joaquin Valley and northern San Francisco Bay area had higher levels of total fluoride than people living in the rest of the state.”

Fluoride levels in drinking waters of the San Francisco-Oakland-San Jose metropolitan area ranged from 0.4 milligrams per liter (mg/L) to 1.7 mg/L.

The highest concentration was in the Oakland-San Leandro-Tustin area, with 0.76 mg/l.

The lowest was in Alameda-Alameda County, with less than 0.07 mg/dl.

In the study area, more than 9 million people were living in homes with a tap water supply, the highest concentration in the state.

The study found the majority of the fluoride in drinking supplies was in tap water, which was not surprising, said study author Daniel J. Lehner, an epidemiologist at the University of California, San Francisco.

“In a lot of these cities, they are not getting the amount of fluoride they need,” Lehner said.

“It’s very difficult to get enough water from water systems to get through the filter.”

In the San Diego area, the average fluoride level was 0.6 mg/liter, which is less than the national average.

Lehnert said the California water system has made a lot more progress in recent years.

“We’ve had a number of different water system reforms over the last 10 years, and I think that’s one of the reasons why we’ve been able to get a good water quality picture, he said.

The researchers also found that the average concentration of lead in drinking supply water was 0% of the national level, which they say is a significant problem.

Lead contamination in drinking wells has been linked to several health problems including reduced IQ, behavioral disorders, and ADHD.

Lead is found in soil, groundwater, and drinking water in the U.S., and the California Department of Health and Human Services estimates it has an estimated global population of more than 3.6 billion.

The lead level in water supplies varies widely by state, and is usually higher in urban areas.

There’s not enough data to know exactly how many people in LA are using fluoridated drinking water to the same extent as other areas,” he said, adding the researchers are studying how fluoridation affects the health of the general population.

of Health & Human Services said in a statement that the state is working with local and federal partners to improve the quality of drinking water and that the California Environmental Protection Agency is also conducting a study of drinking fluoridation levels in the Bay Area.
