Don’t Drink from your Garden Hose

Otherwise, here are the main take-home messages:
Read the label: Avoid hoses with California Prop 65 warnings that say “this product contains a chemical known to the State of California to cause cancer and birth defects and other reproductive harm.” Never drink or fill swimming pools with water from a hose that isn’t clearly labeled “Lead Free” or “Drinking Water Safe.”
  • Let it run: Always let your hose run for a few seconds before using, since the water that’s been sitting in the hose will have the highest levels of chemicals.
  • Avoid the sun: Store your hose in the shade. The heat from the sun can increase the leaching of chemicals from the PVC into the water.
  • Don’t drink water from a hose: Unless you know for sure that your hose is drinking water safe, don’t drink from it. Even if it is labeled safe for drinking, flush it out first before sipping. It’s also a good idea to wash your hands after handling a hose since lead can transfer to your hands and then from your hands to your mouth when eating. Even low levels of lead may cause health problems.
  • Buy a Lead-free hose: One easy way to cut down on the amount of lead in your immediate environment is to get a lead-free garden hose. Not only will it drastically reduce the amount of lead being deposited in your yard, it will also virtually eliminate direct exposure when watering by hand or tending to the garden. A lead-free garden hose is also safe for children to get a much-needed drink or play in the sprinklers, and pets will also be spared of potential lead poisoning from water bowls filled from the hose. The hoses are often white with a thin blue stripe, and are commonly sold in marine and recreational vehicle (RV) stores. An RV lead-free garden hose can also come in a beige color with blue stripe, to match the beige paint of many RVs. Although sold for RV and marine use, these hoses serve as great lead-free garden hoses.
  • Test your soil: It a great idea to check the nutrient levels, but you can also check the levels of metals like lead. Another important source of lead includes lead paint.
  • It’s not just lead: Our test also detected phthalate plasticizers in both the PVC hose materials and in the water left standing in a PVC hose. Some of these phthalates are the same phthalates which have been banned in children’s products. We also detected bisphenol A (BPA) in water left standing in a PVC hose. BPA is used as an antioxidant in polyvinyl chloride (PVC) plastics and as an inhibitor of end polymerization in PVC.
  • Avoid PVC: PVC needs potentially hazardous additives and stabilizers’ to make it “rubbery”. Instead, try a top-quality, food grade polyurethane hose that meets Food and Drug Administration (FDA) standards or an old fashion natural rubber hose. Search on-line “polyurethane garden hose” or “rubber garden hose” for options.
  • Watch the brass: The Safe Drinking Water Act (SDWA) limits lead in brass in residential water fixtures to no more than 2,500 ppm. Garden hose ARE NOT regulated by the SDWA, and our test show 29% of brass connectors contained greater than 2,500 ppm lead. Opt for a hose that is drinking water safe and lead free. Non-brass fittings (nickel, aluminum or stainless) are more likely to lead-free.
