The group believes the City of Lynnwood has violated state rules on the use of pesticides, citing at least one overuse of a fungicide and several cases of incomplete or missing paperwork. State agriculture officials confirmed the organization’s findings, but called the violations minor. The Department of Ecology has 90 days to respond to the request.

The Sierra Club has asked state officials to demand the City of Lynnwood to conduct a soil investigation at Lynnwood (Wash.) Municipal Golf Course, the Seattle-based King5 reported.

The group believes the city has violated state rules on the use of pesticides, King5 reported.

Bill Lider, an environmental engineer and member of the Snohomish Group of the Washington State Chapter of the Sierra Club, said he studied years of pesticide use at the city-owned course and found at least one case of overuse of a fungicide and several cases of incomplete or missing paperwork, King5 reported.

State agriculture officials investigated and confirmed Lider’s findings, but called the violations minor, King5 reported.

Lynnwood Parks Superintendent Bob Colinas said there was some paperwork lost during a move of the course’s former manager, but said the staff is very careful on how it orders and applies pesticides, King5 reported.

The Sierra Club argues the course’s paperwork cannot be trusted and the only way to find out if the soil or groundwater has been contaminated is to conduct a soil investigation, King5 reported.

The Department of Ecology has 90 days to respond to the request, King5 reported.
