**Updated March 2, 2022 to include current data

Our Water Nerds updated our assessment of Long Beach, California drinking water to include the most current data. Our team has aggregated water quality test data from Long Beach Water, the U.S. Environmental Protection Agency (EPA), and internal data that we collect and analyze. We cross reference these data with toxicity studies in scientific and medical literature. With this information, we're able to build a filter that is optimized to remove contaminants in Long Beach drinking water.

Source Of Long Beach Drinking Water

Long Beach drinking water comes from both surface and groundwater sources. 58% is supplied from local groundwater wells in the Long Beach and Lakewood area. The remaining 42% is imported surface water from the Colorado River. This surface water is delivered through the Colorado River Aqueduct, originating at Lake Havasu.

Arsenic In Long Beach Drinking Water

Arsenic is a toxic metal that is known to cause cancer and other health issues. Unlike lead, which distributes into water from plumbing, arsenic comes from the source water itself. Although the city of Long Beach is in compliance with EPA water quality standards, but it's important to acknowledge that EPA standards for arsenic balances the toxicity against the costs of removing it from drinking water. According to the most recent report, the highest concentration detected in Long Beach drinking water is 2.5 parts per billion. Hydroviv recommends that anyone with more than 1 part per billion take steps to remove arsenic from their water.

Lead In Long Beach Drinking Water

Lead enters tap water through older lead service pipes and lead-containing plumbing. When corrosion control measures put in place by the municipality fail (like what recently happened in Flint, Michigan), lead leaches into the drinking water, and can reach dangerous levels. Homes built before 1986 were most likely built using lead pipes and plumbing. The EPA, CDC, and American Academy of Pediatrics, all acknowledge that there is no safe level of lead for children.

Chromium 6 In Long Beach Drinking Water

Chromium 6 is a highly toxic metal that is not regulated by the EPA. In recent years, the concentration of chromium 6 in Long Beach tap water averaged 63 parts per trillion. This level is 3 times higher than the concentration determined to have negligible impact on cancer risk. California tried to set a Public Health Goal (PHG) of 20 parts per trillion for chromium 6 in drinking water. After a lawsuit in 2017, the PHG was redacted because municipality were unable to meet the standards.

Disinfection Byproducts (DBPs) In Long Beach Drinking Water

DBPs are a category of emerging contaminants that form when chlorine-based disinfectants react with naturally-occurring organic matter. Although these chemicals are not currently regulated very well, the EPA has admitted that they are associated with an increased risk of bladder cancer, as well as kidney, liver, and central nervous system problems.

**Updated June 18, 2021 to include current data

Our team of Water Nerds has updated our report of Virginia Beach to include the most recent available data. We aggregated information from the City of Virginia Beach Public Utilities, the U.S. Environmental Protection Agency (EPA), as well as from samples that we collect and analyze. We cross reference these data with toxicity studies in the scientific literature and look at upcoming regulatory changes. The water filters that we build for our customers in Virginia Beach are optimized with these data in mind.

Source Of Virginia Beach Drinking Water

Virginia Beach gets its drinking water from Lake Gaston. The water is delivered from Lake Gaston to Lake Prince, where it's then treated and distributed by the city. Lake Gaston provides an average of 34 million gallons per day (MGD) of water to Virginia Beach citizens.

Lead In Virginia Beach Drinking Water

Lead enters the city of Virginia Beach's water through old lead service pipes and lead-containing plumbing. When corrosion control measures fail (such as what happened in Flint, Michigan), lead leaches into the drinking water and can reach toxic levels. According to the most recent data, the 90th percentile concentration in Virginia Beach is <2 parts per billion. That being said, EPA, CDC and American Academy of Pediatrics all recognize that there is no safe level of lead for children.

Chromium 6 In Virginia Beach Drinking Water

Chromium 6 is a highly toxic metal that, while monitored, is not regulated by the EPA. Virginia Beach’s tap water quality recently averaged 71 parts per trillion for chromium 6. For a bit of perspective, Virginia Beach drinking water is 3.5 times higher than the concentration determined to have a negligible impact on cancer risk.

Disinfection Byproducts (DBPs) In Virginia Beach Drinking Water

DBPs are a category of emerging contaminants that form when chlorine-based disinfectants react with naturally-occurring organic matter. Although these chemicals are not well regulated, the EPA has concluded that they are associated with an increased risk of bladder cancer, as well as kidney, liver, and central nervous system problems.

Still Have Questions About Virginia Beach’s Tap Water?

Hydroviv is a water filtration company that uses water quality data to optimize water filters for each city’s water. The chemicals that we list above are what we consider to be “points of emphasis” so we can build the best water filter for Virginia Beach tap water, but all of our water filters provide broad protection against other contaminants commonly found in drinking water.

***Updated to include most current water quality data

For Hydroviv’s assessment of Sacramento drinking water, we analyzed the most recent water quality test data from the Sacramento Suburban Water District, the U.S. Environmental Protection Agency (EPA), as well as samples that we collect and analyze. Our Water Nerds then research scientific and medical literature to help determine susceptibilities in your water. The water filters we build for people in Sacramento are optimized to remove the following contaminants.

Source Of Sacramento Drinking Water

Sacramento is split into four service areas: (1) Arden Park Vista, Northgate, and Southwest Tract, (2) Hood, East Walnut Grove, and Delta Estates (3) Laguna, Vineyard, Country Creek Estates, and Grantline (4) Mather, Sunrise, and Anatolia. All four of these sources draw water from local groundwater wells, as well as supplementary surface water treated by the San Juan Water District (SJWD) and the City of Sacramento. Click here if you'd like more information on where your water comes from.

Arsenic In Sacramento Drinking Water

Arsenic is a toxic metal that is known to cause cancer and other adverse health issues. Unlike lead, which distributes into water from plumbing, arsenic comes from the source water itself. The levels in Sacramento While the average arsenic concentrations are low in Sacramento, there were groundwater samples that reached 4 parts per billion. Arsenic levels in Sacramento range from 3.7 to 9.9 parts per billion. These levels are extremely close to the federal standard of 10 parts per billion, which takes into account the cost of removing arsenic from municipal systems. This means that the 10 part per billion threshold does not fully take into account public health . We highly recommend that anyone with more than 1 part per billion take steps to remove arsenic from their water, especially if they have children.

Extremely High Levels Of Chromium 6 In Sacramento Drinking Water

Sacramento's drinking and tap water has some of the highest levels of chromium 6 among major US cities. Chromium 6 is a highly toxic metal that is not currently regulated by the EPA. In recent years, Sacramento tap water has averaged around 4000 parts per trillion for Chromium 6 (in all four service areas), with concentrations reaching over 8000 parts per trillion. For the sake of perspective, the average levels are a staggering 200 times HIGHER than the concentration determined to have negligible impact on cancer risk. 

Lead Levels In Sacramento Tap Water

Lead enters into a Sacramento consumer’s drinking and tap water through old lead service pipes and lead-containing plumbing. When corrosion control measures fail (such as recently happened in Flint, Michigan), lead leaches into the drinking water and can reach toxic levels. Recent sampling for lead in Atlanta found that roughly 10% of samples were above 7.8 parts per billion. While the regulatory limit is 15 ppb, both the EPA and CDC recognize that there is no such thing as a safe level of lead.

Disinfection Byproducts (DBPs) Levels In Sacramento's Drinking Water

DBPs are a category of emerging contaminants that form when chlorine-based disinfectants react with naturally-occurring organic matter. Although these chemicals are not currently regulated very well, the EPA has admitted that they are associated with an increased risk of bladder cancer, as well as kidney, liver, and central nervous system problems.

**Updated May 17, 2021 to include current data

For Hydroviv’s assessment of Oakland, California drinking water, our Water Nerds aggregate data from various sources. In this report, we've assessed the most recent available data provided by the East Bay Municipal Utility District, the U.S. Environmental Protection Agency (EPA), as well as from samples that we collect and analyze. Our team then cross reference these data with toxicity studies in scientific and medical literature. The water filters that we build and sell at Hydroviv are optimized to removed contaminants in Oakland tap water.

Source Of Oakland Drinking Water

The city of Oakland gets its water from the Mokelumne River Watershed, which is at the foothills of the Sierra Nevada mountain range. The remaining water is supplied by the East Bay Watershed.

Lead In Oakland Drinking Water

Lead enters tap water through older lead service pipes and lead-containing plumbing. When corrosion control measures put in place by the municipality fail (like what happened in Flint), lead drains into the drinking water, and can reach dangerous levels. Though Oakland's water quality is within compliance with federal regulations, the EPA, CDC, and The American Academy of Pediatrics all acknowledged that there is no safe level of lead, and federal regulations do not take into account levels measured at an individual tap.

Chromium 6 In Oakland Drinking Water

Chromium 6 is an extremely toxic metal that is not currently regulated by the EPA. In recent years, Oakland's tap water quality averaged 50 parts per trillion. For the sake of perspective, these levels are nearly 3 times higher than the concentration determined to have negligible impact on cancer risk.

Disinfection Byproducts (DBPs) In Oakland Drinking Water

DBPs are a category of emerging contaminants that form when chlorine-based disinfectants react with naturally-occurring organic matter. Although these chemicals are not currently regulated very well, the EPA has admitted that they are associated with an increased risk of bladder cancer, as well as kidney, liver, and central nervous system problems.

**Updated May 3, 2021 to include current data

Our Water Nerds have updated our water quality assessment for San Francisco drinking water. We used the most recent 2020 test data from San Francisco Water, Power & Sewer, the city’s water provider and the U.S. Environmental Protection Agency (EPA), as well as from samples that we collect and analyze. We cross reference these data with toxicity studies in the scientific and medical literature, and delve into upcoming regulatory changes. The custom water filters that we offer at Hydroviv are optimized with San Francisco's water quality in mind.

Source Of San Francisco Drinking Water

San Francisco source water originates from the Tuolmne River, and is stored in the Hetch Hecthy Reservoir. Water from the Hetch Hetchy is supplemented with water from local watersheds such as the Alameda, Peninsula, San Andreas, and Pilarcitos reservoirs. Emergency supplies include Lake Eleanor, Lake Cherry and tributaries of the Lower Cherry Aqueduct, Early Intake Reservoir and Tuolumne River.

Lead In San Francisco Drinking Water

Lead enters tap water through older lead service pipes and lead-containing plumbing. When corrosion control measures put in place by the municipality fail (like what recently happened in Flint, Michigan), lead leaches into the drinking water, and can reach dangerous levels. 10% of samples analyzed for lead are 6 parts per billion in San Francisco drinking water. Though in compliance with federal regulations, EPA, CDC and American Academy of Pediatrics all acknowledge that there is no safe level of lead for children. 

Chromium 6 In San Francisco Drinking Water

Chromium 6 is a highly toxic metal that is not regulated by the EPA. In recent years, San Francisco’s drinking and tap water has averaged 90 parts per trillion for Chromium 6. For a bit of perspective, Chromium 6 levels in San Francisco's tap water quality are 4.55 times higher than the concentration determined to have negligible impact on cancer risk.

Disinfection Byproducts (DBPs) In San Francisco Drinking Water

DBPs are a category of emerging contaminants that form when chlorine-based disinfectants react with naturally-occurring organic matter. EPA regulates two categories of DBPs: Total Trihalomethanes (TTHMs) and Haloacetic Acids 5 (HAA5). Although these chemicals are not currently regulated very well, EPA discloses that high levels of disinfection byproducts are associated with an increased risk of bladder cancer, as well as kidney, liver, and central nervous system problems.

Chloramine Used To Disinfect San Francisco Drinking Water

While most municipalities use chlorine as the primary disinfectant, San Francisco’s water is disinfected with chloramine (produced by mixing chlorine and ammonia). Chloramine is primarily responsible for what many customers report as the “bad taste” of tap water, and unlike chlorine does not dissipate if a container of water is left in the refrigerator overnight. Most one-size-fits-all water filters use filtration media that doesn’t do a great job removing chloramine, but the filters that we design and build at Hydroviv for San Francisco uses special filtration media that is purposefully designed to remove chloramine as well.

Still Have Questions?

Per and Polyfluoroalkyl Substances (PFAS) are being identified in a growing number of municipalities across the United States. San Francisco has not yet tested for PFAS, but several variations have been detected throughout the state of California. Not all water filters are designed to remove PFAS from drinking water.

Hydroviv is a water filtration company that uses water quality data to optimize water filters for each customer's water. The contaminants that we list above are what we consider to be major “points of emphasis” that we use to build water filters that are built specifically for San Francisco, but all of our filters provide broad protection against a wide range of contaminants.
