Vilsack, the former Iowa governor, has supported farmers’ voluntary efforts to improve water quality but also has criticized state leaders for not developing a comprehensive water quality initiative after Des Moines Water Works filed a federal lawsuit against drainage districts in three northwest Iowa counties over nitrate pollution.
