Just when you think you have thought of everything, think again. Water hoses can contain toxic levels of lead, cadmium, tin, mercury, arsenic, antimony, bromine, chlorine, phthalates and bisphenol A (BPA).
I decided to buy a new one and after much research settled on the Water Right 600 series water hose and the Water Right Soaker hose. Both on Amazon. At the very least in my opinion for your garden you should use a hose labeled drinking water safe even though they are not perfect. The polyurethane hoses are the best and expensive but are free of all chemicals. The Water Right hose is made in the USA
