For Hydroviv’s assessment of Providence, Rhode Island’s drinking water, we collected water quality test data from Providence Water and the U.S. Environmental Protection Agency. We cross referenced the city’s 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 Providence drinking water.

Lead In Providence’s Drinking Water

Providence, Rhode Island has been in exceedance of the federal lead Action Level since 2005. The water quality report released in 2020 found that lead levels in Providence are currently 16 parts per billion. Data released in 2019 found that 10% of samples had lead levels over 22.3 parts per billion. Lead enters tap water through old lead service pipes and lead-containing plumbing. Environmental Protection Agency, Center for Disease Control, and American Academy of Pediatrics all recognize that there is no safe level of lead for children. The data provided by the city may not be representative of the actual scope of the lead problem in Providence, RI because only 301 homes were tested for lead. Hydroviv strongly encourages Providence residents to take advantage of the city’s free lead testing program. Under this program, residents can pick up a free kit to test for lead in their drinking water at the Providence Water customer service location. For more information call 401-521-6303.

Disinfection Byproducts In Providence's Water

Providence Water also has elevated levels of Disinfection Byproducts or DBPs. EPA regulates two categories of DBPs: Total Trihalomethanes (TTHMs) and Haloacetic Acids-5 (HAA5). The average concentration of TTHMs was 71.8 parts per billion which is just under EPA's standard of 80 parts per billion for drinking water. DBPs are a category of emerging contaminants which means they have been detected in drinking water but the risk to human health is unknown. DBPs are formed when when chlorine based disinfectants are routinely added to the water supply to kill bacteria. 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. Some disinfection byproducts have almost no toxicity, but others have been associated with cancer, reproductive problems, and developmental issues in laboratory animals. 200 million people in the United States use chlorinated tap water as their primary drinking source, so we take understanding their full health effects very seriously, even if federal agencies fail to regulate all categories.

Per and Polyfluoroalkyl Substance (PFAS) In Providence Drinking Water

PFAS are a category of emerging contaminants that have been detected in a growing number of water supplies across the United States. PFAS have been associated with an increased risk of cancer, an increased risk of miscarriages, and other adverse health effects. PFAS have been detected in water supplies throughout the state of Rhode Island. Because they are not regulated, cities like Providence are not required to test, monitor, or remove them from drinking water.Not all water filters are able to remove PFAS from tap water.

Where Does Providence Source Its Drinking Water?

Providence sources its drinking water from the Scituate Reservoir, which is located 15 miles east of the city. The Scituate Reservoir has tributaries that flow in and out of several other reservoirs including the Regulating, Barden, Ponaganset, Westconnaug, and Moswansicut reservoirs. The Providence Water system has approximately 1,040 miles of transmission and distribution mains.

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.
