Hey guys...let's keep it constructive.
I disagree with ShineShop and applaud Len_A for a very reasoned reply..save for the @$%#*# :~)... but ShineSHop reopened this discussion and good things can come of it.
Let's throttle back the discourse and .. as TDMAN said ... get back to the issue of a solution.
Peter
Point taken, and edited!! And thanks, too.
Sorry for the ferocity of the response, but somethings get my goat, and the the way a few in the environmental crowd have blown out of proportion something as simple as washing your own car.........
Well, let's just say it makes me pretty mad.
Back to the discussion at hand, something to consider:
When the average person washes his or her own car, you're using about two ounces to maybe four ounces of soap, most of which has a neutral pH. I wasn't kidding when I said that quite a few waste water treatment plant managers gripped about commercial car washes. I have no first hand knowledge of the pH of commercial car wash detergent, but almost all of know it CAN (not always IS) strong enough to strip some of the weaker waxes off a cars finish, and at the very least, shorten the life of many waxes.
Two to maybe four ounces of pH neutral soap.
Look at fertilizing your lawn. I have NO CLUE what the average lot size is, so I'm going to talk about mine - my lot is about 80 wide by 120 feet deep. Because of my dog's allergies, I stopped using chemical fertilizers like Scott's, and switched to organics, like Ringer's Lawn Restore, which I use three times a year, alternated monthly with Aggrand liquid organic fertilizer.
I didn't do this to be a tree-hugger - those people give me a rash. Little did I know that I was helping the environment, and that was after years of calling on the waste water treatment plants (god, am I a rocket scientist...NOT!). I found out that even though the numbers on the Ringers was lower -Ringers is a 10-2-6 fertilizer, it was a slow release, so it didn't wash down the sewer. Scott's is a 30-3-4 - 30% nitrogen. And it dissolves in water quickly, and according to my local city government, contaminates not only the the ground water, but the Detroit River.
How? You figure that a 25 pound bag is seven and a half pounds nitrogen, about half of which will dissolve so quickly that a good rain storm or over watering will send it down the sewer. 3.75 pounds of nitrogen to make algae grow like nuts and kill off the fish. On my lot, from April to October, I'll easily use a 25 pound bag of Scot's if I still used that type. So just my house could, in theory, send 3.75 pounds of nitrogen down the sewer every year. Multiply that in my subdivision by 125 houses, and you got a problem.
Compare that to two to four ounces of car wash soap. Even if it were a "major" pollutant, out of two to four ounces of car wash soap, one question to ask is this:
How much of it is WATER? That's when it's in the package. Because gentlemen, it ain't all soap. Even if I washed my car every week, from April to October, that's just me washing my car. You want to know how many of us actually wash their own cars, in their own driveways in this sub? My lazy butt neighbors (yea, I tell'em that to their face when they raze me about detailing my cars)? Maybe twenty to twenty-five of us, plus three RV's that get washed maybe twice a year.
How the hell can that compare to nearly four pounds of nitrogen hitting the sewers every year, multiplied by 125 house. 3.75 time 125 equals about 469 pounds of excess nitrogen polluting the storm sewers.
You think I'm exaggerating about the fertilizer? This is one of at least three websites in Metro Detroit telling people to use organic fertilizers
Link, and you think anyone listens? And that's on top of a monthly mailing my city and every city near me does from May to September. Lowe's carries Milorganite, and Scott's out sells it, according to closest store to me, by about 20 to 1, Home Depot caries Ringers, and that manager said Scott's and the other chemical fertilizers out sell Ringers by over 40 to 1.
And some genius wants us to stop washing cars in our own driveways and use commercial car washes instead, after water treatment professionals have told me that home do-it-yourself-car-washing isn't a huge problem.
Smells like a commercial industry scam to me.
