Washougal and other cities have a message: Please pick up after your pet.
When pet owners don’t, rainwater carries the waste into drains, ditches, lakes and rivers.
“If people forget their bag, they think, ‘Well, it’s natural. It will decompose.’ And that’s not the case. Bacteria and pathogens are in pet waste,” said Rita Fallin, stormwater program coordinator for Washougal.
While dog waste can take a couple months to break down in warmer, humid climates, here in the Pacific Northwest it can take six months to a year or longer. Meanwhile, rain carries fecal matter bit by bit into nearby water sources. E. coli, salmonella, giardia and roundworms can end up in fish and shellfish in the river, which can then be passed on to humans.
Fallin said the city gets a lot of complaints about pet waste left behind at city parks, especially at Schmidt Family Park and Elizabeth Park, both near the Washougal River.
To demonstrate the severity of the problem, Washougal staff went to both parks in January to plant yellow flags at every waste spot they could find, an idea Fallin said she copied from Kirkland.
