I spent the fall in 05 traveling New England, staying in various campgrounds in Massachusetts, Maine, VT, NH, NY and CT. I chose the best ones I could find in the areas I wanted to be. Had a lovely time, but since most of these campgrounds are older, I guess, I found the water situation to be just awful. I have 3 water filters. Two whole house filters on the outside and a ceramic one inside for drinking water only. I also filter my drinking water through a PUR filter pitcher. I travel all over the US and have never encountered such consistently bad water as I did in New England. Normally I replace a sediment pre-filter about one per month or less, the main heavy duty filter about once every 3-6 months and I clean the ceramic filter every month. I could not go two weeks ( I came to find out) on my sediment filter without it being MUDDY brown which also destroyed my heavy duty filter in a month (used 2 in 2 months time @ $30.00 a piece :angry: ) I wish I would have checked the filters at every campground but I was not expecting that problem to be so bad. After I got to Washington DC and ever since going south, my filters have barely shown much contamination. I changed sediment filters twice since November 1 and I actually could have used them longer. I have never encountered anything like it. I did get into some bad iron water that fouled a brand new set of filters( and tanks, lines etc...) at a KOA in Iowa... but that is another story about KOA I will save for a different post. I put it in my review. I would just post this to anyone traveling in New England to be wary of the water in these campgrounds as they must not be keeping up with their infrastructure needs since they are so seasonal. I can see how dirty my filters get, when I open up the canisters, but I know many people use completely encased filters so you cannot tell when they are contaminated. I am telling you the filters turned muddy brown within 2 weeks. And I always flush the line out first in case there is stuff in the water line. That did not make a difference. It makes me wonder if anyone ever checks their water quality in those campgrounds I guess if everyone drinks bottled water they wouldn't care. Being a fulltimer, I don't like to buy bottled water.
