For Hydroviv’s city of Hartford, Connecticut's drinking water quality report, we collected water quality test data from Hartford's annual Consumer Confidence Report and the U.S. Environmental Protection Agency. We cross referenced water quality data with toxicity studies in scientific and medical literature. The water filters that we sell at Hydroviv are optimized to filter out contaminants that are found in Hartford's drinking water.

Where Does Hartford Source Its Drinking Water?

Hartford sources its drinking water from surface water reservoirs throughout the massive Farmington River Watershed. Because Hartford’s source water is entirely surface, pollution that’s discharged into the river or its tributaries has the potential to enter drinking water. Hartford, as well as the rest of the state of Connecticut, has a long industrial history. Hartford drinking water has contaminants associated with industrial activities such as Strontium, Barium, Vanadium and Chromium 6. Additionally, hormones caused by household waste were detected in the city of Hartford's most recent drinking water quality report. 

Lead In Hartford Drinking Water

Hartford is an older city, so it’s no surprise that lead contamination is a big problem. Lead enters tap water through old lead service pipes and lead-containing plumbing. 10% of sites tested for lead had concentrations over 4 parts per billion. But the highest level detected in Hartford drinking water was 148 parts per billion. Environmental Protection Agency, Center for Disease Control, and American Academy of Pediatrics all recognize that there is no safe level of lead for children. Additionally, municipalities are only required to test a handful of homes every few years, so the levels reported in Hartford’s annual water quality report might not reflect the lead levels in your tap water. Lead exposure can cause developmental issues, lowered IQ, and damages to the kidneys and brain.

Disinfection Byproducts In Hartford Drinking Water

Hartford also has a serious problem with disinfection byproducts or DBPs. DBPs are formed when chlorine-based disinfectants that are routinely added to the water supply to kill bacteria, react with organic matter. In this years report, concentrations of haloacetic acids ranged from 7.7 to 38.2 parts per billion and 15.3 to 72.8 parts per billion for trihalomethanes. For a bit of perspective, EPA’s maximum contaminant level for haloacetic acids is 60 parts per billion and 80 parts per billion for trihalomethanes. While Hartford's water quality is technically in compliance with EPA’s threshold, regulatory agencies have very little knowledge about the adverse health effects of DBPs, and their toxicity. EPA has stated that they have been linked to an increased risk of bladder cancer, as well as kidney, liver, and central nervous system problems.

For Hydroviv’s assessment of Jackson, Mississippi drinking water, we collected water quality test data from Jackson's annual Consumer Confidence Report and the U.S. Environmental Protection Agency. We cross referenced Jackson water quality data with toxicity studies in scientific and medical literature. The water filters that we sell at Hydroviv are optimized to filter out contaminants that are found in Jackson drinking water.

High Lead Levels in Jackson Drinking Water

Lead enters tap water through old lead service pipes and lead-containing plumbing. 10% (or the 90th percentile) of taps tested for lead contamination had concentrations over 8 parts per billion. However, last year the 90th percentile was 16 parts per billion. It's unusual to see a municipality improve lead levels this drastically in just one year. The federal action level for lead is 15 parts per billion, but agencies such as the Center for Disease Control and American Academy of Pediatrics recognize that there is no safe level of lead for children. Additionally, municipalities are only required to test a handful of homes every few years, so these super high levels reported in Jackson’s annual water quality report might not even reflect the lead levels coming from your faucet. Lead exposure can cause developmental issues, lowered IQ, and damages to the kidneys and brain. In August of 2018, the city of Jackson sent a notice to all residents acknowledging the lead violation. The notice gave standard recommendations for preventing lead exposure, such as allowing tap water to run for 2 minutes before use, avoiding hot water for drinking or cooking, eliminating tap water for baby formula, and getting your child’s lead levels checked by a doctor.

Disinfection Byproducts In Jackson Drinking Water

DBPs are formed when chlorine-based disinfectants that are routinely added to the water supply to kill bacteria, react with organic matter. According to the most recent report, concentrations of haloacetic acids averaged 54 parts per billion but reached levels as high as 45 parts per billion. Concentrations of trihalomethanes averaged 58 parts per billion but reached levels as high as 68 parts per billion. For a bit of perspective, EPA’s maximum contaminant level for haloacetic acids is 60 parts per billion and 80 parts per billion for trihalomethanes. Health and regulatory agencies have very little knowledge about the adverse health effects of DBPs, and their toxicity. EPA has stated that they have been linked to an increased risk of bladder cancer, as well as kidney, liver, and central nervous system problems.

Chromium 6 In Jackson Drinking Water

Chromium 6 is a highly toxic metal that is currently unregulated by the EPA. Chromium 6 pollution is associated with metal processing, tannery facilities, chromate production, stainless steel welding, and pigment production. Concentrations of Chromium 6 average 48.5 parts per trillion. This is double the concentration determined to have a negligible impact on cancer risk. EPA has acknowledged that Chromium 6 is a known human carcinogen through inhalation, but is still determining its cancer potential through ingestion of drinking water. Lung, nasal and sinus cancers are associated with Chromium 6 exposure. Ingestion of extremely high doses of chromium 6 compounds can cause acute respiratory disease, cardiovascular, gastrointestinal, hematological, hepatic, renal, and neurological distress which may result in death.

For Hydroviv’s assessment of the city of Boynton Beach, Florida's drinking water, we collected water quality test data from the annual Boynton Beach Consumer Confidence Report and the U.S. Environmental Protection Agency. We cross referenced Boynton Beach water quality data with toxicity studies in scientific and medical literature. The water filters that we sell at Hydroviv are optimized to filter out contaminants that are found in Boynton Beach drinking water.

Disinfection Byproducts In Boynton Beach Drinking Water

Let’s start with Disinfection Byproducts or DBPs. DBPs are formed when chlorine-based disinfectants that are routinely added to the water supply to kill bacteria, react with organic matter. Boynton Beach water quality has some pretty high levels of disinfection byproducts. According to the most recent report, concentrations of haloacetic acids averaged 26 parts per billion but reached levels as high as 33.7 parts per billion and concentrations of trihalomethanes averaged 74.8 parts per billion but reached levels as high as 149 parts per billion. For a bit of perspective, EPA’s maximum contaminant level for haloacetic acids is 60 parts per billion and 80 parts per billion for trihalomethanes. Health and regulatory agencies have very little knowledge about the adverse health effects of DBPs, and their toxicity. EPA has stated that they have been linked to an increased risk of bladder cancer, as well as kidney, liver, and central nervous system problems.

Chloramine In Boynton Beach Drinking Water

While most cities use chlorine, Boynton Beach uses chlorine and chloramine in the disinfection process. Chloramine is primarily responsible for what many customers report as the “bad taste” or “pool smell” of tap water. Concentrations of chloramine averaged 3.01 parts per billion but reached concentrations as high as 4.8 parts per billion. Again for a bit of perspective, the maximum contaminant level for chloramine is 4 parts per billion.

Our Water Nerds have been closely following the environmental and public health disaster in North Carolina for a while now. This article provides an overview of the recent consent order, and some background information on what's going on in North Carolina. 

The Chemours Plant in Fayetteville, North Carolina has been discharging various per and polyfluoroalkyl substances (also known as PFAS) for decades. PFAS are a category of emerging contaminants that are found in some of the most popular consumer products such as Scotchgard, Gore-Tex, Teflon, and other stain/water resistant products. PFAS is also an important ingredient in firefighting foam, which has been a major source of water contamination throughout the country. In recent years, a replacement chemical for PFOA called GenX has dominated the conversation, particularly in North Carolina. In November 2018, EPA admitted that GenX is “suggestive” of cancer, which is significant for residents who have been unknowingly exposed.

$13 Million Awarded to NCDEQ

Chemours is awarding $13 million to the North Carolina Department of Environmental Quality in the form of civil penalties and investigative costs. In comparison to other PFAS-related settlements, this is by far one of the smallest. In early 2018, 3M paid the state of Minnesota $850 Million in environmental degradation. In 2017, DuPont was involved in a $670.7 million settlement in the Mid-Ohio Valley region for PFAS water contamination.

Overview Of The Consent Order

The Consent Order clearly lays out a timeline of air emission goals and wastewater discharge stipulations. Chemours’ National Pollution Discharge Elimination System (NPDES) permit was revoked in early 2017 and the new Consent Order prohibits any sort of wastewater discharge until a NPDES permit is reallocated. Chemours must also create laboratory methods and test standards for all PFAS compounds released by the Fayetteville plant. Basic remediation plans must be agreed upon by the North Carolina Department of Environmental Quality, North Carolina River Keepers, and Chemours. Chemours will also pay for water filtration for water filtration for residents on private wells. Concentrations of GenX must be above 140 parts per trillion or any updated health advisory, in order to be eligible for a filter. GenX is not the only PFAS compound detected in the Cape Fear area, and the consent order addresses that. the Residents can also be eligible for filtration if other PFAS compounds are detected in well water over 10 parts per trillion individually, and 70 parts per trillion combined. NCDEQ is currently seeking public comment regarding the recent settlement.

How Are Cape Fear Residents Responding?

Cape Fear Public Utility Authority (CFPUA) created a comprehensive breakdown of the Chemours consent order. The utility provider acknowledged that the settlement did not go far enough to cover the scope of GenX and PFAS water contamination in the Cape Fear area. In a press release, CFPUA talked about how the consent order did not acknowledge the PFAS sediment pollution at the bottom of the Cape Fear River. Any sort of dredge or fill could disturb the sediment and create GenX concentrations to sky rocket in drinking water. Local non-profit groups are also not in agreement with the Chemours settlement because they believe it does not go far enough to mitigate the scope of PFAS water contamination. The current consent order places most of the mitigative costs water utility providers which would of course be paid for by taxpayers.

Our Take:

In early November of 2018, EPA released a draft toxicity report for GenX, proposing a threshold of 80 parts per trillion for drinking water. The concentration deemed “safe” by North Carolina and Chemours is almost two times higher than what the EPA is proposing as safe. Health and regulatory agencies know very little about the adverse health effects of GenX and other PFAS compounds. It’s up to consumers to decide the best course of action to protect themselves and their families.

For Hydroviv’s assessment of Fresno, California’s drinking water quality issues, we aggregated water quality test data from the City of Fresno Water Quality Division, U.S. Environmental Protection Agency and supplemental health information. We cross referenced these data with toxicity studies in scientific and medical literature. The water filters that we sell at Hydroviv are optimized to filter out contaminants that are found in Fresno’s drinking water.

Where does Fresno Source its Drinking Water?

Fresno sources its drinking water from both groundwater and surface water sources. The city has 260 groundwater wells that draw water from the Fresno Sole Source Aquifer. Additionally, the city draws water from the Millerton and Pine Flat lakes which is delivered to the city via the Fresno Irrigation District canals.

Chromium 6 In Fresno’s Drinking Water

Fresno drinking water has some of the highest levels of Chromium 6 among major cities in the U.S. Chromium 6 is a highly toxic metal that is currently unregulated by the EPA. In the most recent Consumer Confidence Report, the city disclosed that the average concentration of Chromium 6 in drinking water was 2800 parts per trillion, and the highest level detected was 11,000 parts per trillion. For a bit of perspective, the California Water Boards previously set a public health goal of 20 parts per trillion for Chromium 6 in drinking water. Chromium 6 pollution is associated with metal processing, tannery facilities, chromate production, stainless steel welding, and pigment production. EPA has acknowledged that Chromium 6 is a known human carcinogen through inhalation, but is still determining its cancer potential through ingestion of drinking water. Lung, nasal and sinus cancers are associated with Chromium 6 exposure. Acute respiratory disease, cardiovascular, gastrointestinal, hematological, hepatic, renal, and neurological distress are health effects associated with high levels of chromium 6 exposure.

Synthetic Contaminants Found In Fresno's Drinking Water 

1,2 Dibromochloroporpane (DBCP) is a banned nematocide that was developed as a replacement for DDT. It was banned in 1979 but is still extremely persistent in the environment. In this years water quality report the average concentration detected in Fresno's water was 27 parts per trillion and the highest concentration detected was 170 parts per trillion. For a bit of perspective, this level is just under the regulatory limit of 200 parts per trillion. DBCP is an endocrine disruptor that specifically effects the male reproductive system. Additionally, several industrial solvents were detected in Fresno's drinking water. 1,2 Dichloroethylene, Tetrachloroethylene (PCE), and Trichloroethylene (TCE) were among some of the present contaminants. Little is known about their carcinogenic potential or other adverse health effects. Many of these contaminants are the result of industrial discharge, the byproduct of dry cleaning ingredients, or used in metal degreasing. 

Arsenic In Fresno’s Drinking Water

Arsenic is another carcinogenic heavy metal that was recently detected in Fresno’s drinking water. The 2017 Consumer Confidence Report disclosed that Fresno's water problems exceeded the California Public Health Goal of 0.004 parts per billion and was barely in compliance with the loose EPA Maximum Contaminant Level of 10 parts per billion. The highest level detected in Fresno’s water was 5.6 parts per billion and the overall average was 0.7 parts per billion. The Arsenic levels in Fresno were high enough that the city was required to make a statement in their report, notifying residents of the contamination. Arsenic is a toxic substance that is linked to a long list of health problems in humans, including various forms of cancer, and problems with the cardiovascular, immune, neurological and endocrine systems. Unlike several industrial chemicals, arsenic naturally occurs in bedrock. If you use a private well we highly recommend purchasing a filter to remove arsenic from your water.

It’s important to note that only a handful of contaminants are required to be included in annual Consumer Confidence Reports, and that there are hundreds of potentially harmful unregulated contaminants that aren’t accounted for.
