Toxic Garden Tools?

If you’re like me, almost every day you read reports of some new toxic threat in food, water, cosmetics, or household cleaners.

It’s a tough job keeping up, especially distinguishing real threats from the hyper-vigilance of the worried well.

In May the Michigan environmental group Ecology Center released its 2012 Garden Products Study, which reported research that examined 179 common garden products, including hoses, gloves, kneeling pads, and garden tools for evidence of toxic substances.

Researchers found more than two-thirds of the products tested contained high levels of one or more toxic substances (including lead), chemicals linked to many such adverse health effects as “birth defects, impaired learning, liver toxicity, premature births, and early puberty in lab animals.”


Toxic garden hoses?

And unlike standards that govern public drinking water and the infrastructure that delivers it, no regulations establish safety standards for garden hoses and the fittings that connect them. It’s buyer beware.

Especially concerning for me: the number and amounts of number of toxic substances that leach from PVC garden hose.

For years, we’ve run several hundred feet of cheap PVC hose to our various gardens and the food plants inside our solar greenhouse.

Switching to drinking-water safe hose (rubber or polyurethane) and lead-free couplings will require both research and money, so we’ll plan to do it in stages.

In the meanwhile, we’re following the experts’ suggestions for continuing to use our existing hoses:

  • Letting the water run to get the standing water out of the hose before watering food crops
  • Minimizing the hoses' exposure to direct sunlight. The heat of the sun on water stored in the hose increases the amount of toxins leaching from the hose.
  • Not drinking from the hose or using it to water the chickens. If we had pets, we wouldn't fill their water bowls from the hose.
  • Looking for safer hose couplings. Ecology Center’s tests showed that 29 percent of brass hose connectors contained unsafe levels of lead. Researchers suggest non-brass couplings of stainless steel, aluminum or nickel.

Romona, I drank from garden

By Margaret Boyles

Romona, I drank from garden hoses in the 50s, too. They were made from natural rubber. They definitely smelled rubbery on a hot day, and the hoses gradually disintegrated like any natural product.

"hiway" is right. The dangerous polyvinyl chloride hoses that leach lead and other toxins (especially when heated by the sun) weren't even developed until the late 1950s, and took quite a while to achieve the market dominance they enjoy today.

give me a break. did they do

By Romona

give me a break. did they do all this back in the 50's when all my friends drank from hoses and were all fine.

back in the 50's the hoses

back in the 50's the hoses and connection were not all the cheap plastic crap, so we were safer to drink from the hose...today the market is saturated with merchandise that is below par...
