CNEHJ has a Nurses’ WATER TEAM that is helping to educate and engage nurses about health concerns related to water.
Nurses Recognize the Importance of Protecting all our Water
As nurses we know that the human body is about 60 – 70% water. All life requires water to live.
In many indigenous cultures water is a sacred element. And yet… we have been desecrating our water for a long time now – our streams and rivers, our lakes and oceans, and, in turn, our bodies. It is estimated that 1 million people in California do not have access to healthy drinking water.
The California EPA (CalEPA) is responsible for regulating water.
In California, similarly to air quality, the California EPA (CalEPA) is responsible for regulating water and it does this through the California Water Board and regional agencies.
There are two major statutes that apply to our water – the Clean Water Act, which protects our surface and groundwaters and regulates discharges of pollution into US waters and the Safe Drinking Water Act which specifically applies to drinking water. Note: the regulatory measurement for chemicals in our drinking water is called the Maximum Contaminant Level or MCL.
Accessing Information About Your Drinking Water
If you purchase your household water from a public or private water supplier, you have the right to see the results of the tests they perform on 90 plus chemicals, characteristics, and categories. By law, your water company must provide this information to you in the form of a “Consumer Confidence Report”. They will often include it once a year in your water bill.
The CA Office of Environmental Health Hazard Assessment has created a program on Human Right to Water Program and its associated data tool. with which you can find out about your water quality, quantity, and cost.
There is a new family of contaminants of concern in drinking water in surface waters around the state and country – PFAS (per- and polyfluoroalkyl substance). This family of chemicals were developed into stain-resisting products (included in many furniture fabrics and carpeting), grease-resistant products (used to coat to-go containers and other products), and non-stick products (pots and pans and other products). There are over 4,700 chemicals in this family. AND there are a wide range of significant health effects associated with PFAS, see the graphic below:
PFAS are Found in a Wide Range of Everyday Products
There are no federal or state regulations for PFAS in drinking water.
We are awash in these “forever chemicals”, as they have become known, because they do not break down and remain toxic. Water is an important exposure pathway, but there are others as noted in the graphic below:
All states are required to assess their water bodies every two years and develop a plan to address harmful contamination.
As nurses, we should be aware of the results of the state’s water assessments as they pertain to the communities we serve.
Lead is an element that is both naturally occurring in some California water and can be a contaminant caused by leaded pipes and lead solder on pipes. CalEPA has a program with the California Department of Education to assess and address lead in schools. For more California information and resources about lead poisoning specifically for health professionals, see here.
Arsenic is an element that is toxic. Like lead, it is naturally occurring in California’s drinking water. Contamination from arsenic also comes from mining sites, manufacturing processes, and agricultural sources. Arsenic is a known carcinogen and is associated with a range of human cancers – liver, bladder, kidney, lungs, and skin. There are a number of non-cancer health risks, as well, including skin problems, hemopoietic problems, arrhythmias, and peripheral nerve damage. In the map below, the red dots show places where groundwater testing resulted in levels about the Maximum Contaminant Levels. The groundwater locations were places where well-water was obtained.
There is a wide range of ways in which pharmaceuticals are entering our drinking water sources including from treated and untreated domestic sewage in which human excrement and urine contains pharmaceuticals. The US Geologic Services has measured steroids, antibiotics, prescribed hormones, and an array of prescription and non-prescription drugs in waterways throughout the US. Veterinary use of antibiotics for meat animals and poultry has significantly increased the amount of antibiotics present in waterways and the associated development of antibiotic-resistant organisms. For more specific information about pharmaceutical waste in CA water, see the CA Department of Toxic Substance’s page on Pharmaceuticals.
Practice Green Health, a non-profit organization dedicated to improving environmental health and sustainability in hospitals has created a 10-Step Blueprint for Managing Pharmaceutical Waste in Healthcare Facilities.
