For
many of us, summertime means road trips to the beach or mountains, or at the
very least some additional dust and bird poop on the exterior of our vehicles.
The extra dirt leads us to do one of two things: wash our car in the driveway
or head to the car wash. But which choice is better for the environment?
The
main concerns with either choice are the amount of fresh water being used and
the types of chemicals used to remove the dirt. Both of these concerns can be
closely monitored when washing the car at home, says Katy Gresh, spokeswoman
for the Southwest Region of the Pennsylvania Department of Environmental
Protection. She advises car owners to put aside a set amount of water for the
entire wash. "It's just like brushing your teeth," she says,
"You don't want to leave the water running of more than you need for the
job." But even following this advice comes with an environmental risk:
Washing your car in the driveway or street flushes the dirty water into storm
drains.
John
Schombert, executive director of 3 Rivers Wet Weather, his organization works
to educate the public about storm sewers (下水道) and water runoff, keeping this
untreated water from entering the Allegheny region's waterways. "We ask
people to, consider washing their cars on lawns or other permeable (透水的) surfaces where the water gets
absorbed," Schombert says. "Soil can break down and help filter (过滤) those things," Schombert says.
"Storm sewers are not made for waste disposal." Even when car owners
use natural soaps to wash their cars, which Schombert says are probably
ineffective at breaking down grease anyway.
The
commercial car wash down the street knows full well the rules regarding
wastewater in storm sewers. According to the International Carwash Association
(ICA), professional car washes must use water reclamation systems. These
mandated processes not only keep the dirty water out of storm sewers and
regular water treatment systems, but they also work to reduce water usage at
commercial facilities.
