Factory Farms, Fouled Waters
Clean water is vital to our health, our environment, and our quality of life.
Environment Washington Research and Policy Center envisions a future where all of our waterways, from the Puget Sound to Lake Chelan, are clean and our drinking water is safe. One of the most critical steps to achieving this vision is to dramatically reduce pollution from agribusiness operations, specifically at concentrated animal feeding operations (CAFOs) in Washington State.
The estimated 200,000 adult dairy cows in Washington produce over 20 million pounds of manure each day, collectively. It is estimated that 2,500 dairy cows produce a waste load equivalent to a city of 411,000 people. What’s worse, unlike human waste, dairy waste is not treated; instead dairy waste at CAFOs is either stored in manure lagoons or applied to fields.

Unfortunately, given the quantity, manure is often over-applied to fields, and lagoons often contain millions of gallons of liquid waste where decomposing manure results in high concentrations of nitrites and nitrates. The lagoons and over-application not only pollute groundwater and surface water, but also pose a threat to human health, especially to infants.
Groundwater is the drinking water supply for approximately 60 percent of people who reside in Washington state. Several areas of the state with high concentrations of CAFOs have been found to have high levels of nitrates in drinking water. Nitrates are toxins. High doses particularly threaten pregnant mothers, babies, and seniors, causing methemoglobinemia, or "blue baby syndrome," which can be fatal.
Our goal is to raise the profile of the problem of agricultural pollution in our waterways. We know that Washingtonians care about the Puget Sound and clean water, but to change the way this pollution is managed, we need to educate the public and raise the profile and visibility of the problem.
