This same principle holds true even for products used at our cabins that eventually filter down through the earth to our waterways (either directly over land when it rains, or through groundwater percolation that reaches the water bodies). Remember, if possible, the drain outlets should be at least 150 ft away and have some sort of greywater filtration system. Again, we encourage the use of natural and gentle products in our sinks and showers at our camps. Some general guidelines to buying green is to try to get phosphate free, no parabens, and to purchase biodegradable or biocompatible products. If you are interested, the Environmental Working Group (EWG), has rated green products and there are many other sources on the internet that offer similar rating systems – please visit their website for more information on many more products than are listed below. We tried to identify products that have the highest rating in terms of biodegradability and are locally available, but there are many more eco-friendly available.
