The case underscores one of the major problems with CAFOs, which is the massive amount of manure they produce and the manners by which operators dispose of it, which have major environmental implications. According to the EPA, “a single dairy cow produces approximately 120 pounds of wet manure per day,” which is “equivalent to that of 20-40 people.” The quantity of manure produced by one dairy cow can be multiplied on a CAFO by hundreds or, in some cases, thousands of heads. This higher concentration of CAFO animals leads to a higher concentration of animal waste, a problem that holds true for all types of livestock raised in these operations. As CARE describes the scale of the waste problem:

Operations like the Nelson Faria Dairy produce as much waste as a city of over 200,000 people. Unlike cities, however, which treat their wastes, the dairy industry applies manure to agricultural fields primarily to get rid of it.

In moderation, manure is a great soil fertilizer, but the sheer amount (and concentration) of untreated waste generated by CAFOs is a serious liability. When too much manure is spread out over fields for soil to properly absorb it, or when manure lagoons leak, overflow or rupture, rain and stormwater runoff can carry the waste into groundwater and nearby waterways. This over-application or discharge of CAFO animal waste is an egregious example of nonpoint source (NPS) pollution, where the source(s) is diffuse and can have a wide distribution area. Untreated animal waste is a hazard for both public health and ecosystems because it can contain harmful quantities of nutrients, pathogens and heavy metals. (Ecocentric has covered the problems associated with large amounts of untreated CAFO animal waste.)

The case of the improper handling of manure on the Nelson Faria Dairy is typical of the CAFO industry. While state and federal animal waste rules exist, their enforcement is lax at best. As CARE President, Helen Reddout, explained:

The Washington Department of Agriculture had recently inspected the dairy and found that it was doing an excellent job managing its manure. Nothing could be further from the truth…It is now time for the agencies who are supposed to be protecting our health to follow the precedent set by this Order. Our state and federal laws were aimed at protecting people and now it’s time for the agencies responsible for safeguarding public health to do just that.

Reddout goes on to explain the reality of state agency CAFO inspections:

Washington Departments of Ecology and Agriculture (WSDA) are supposed to monitor and regulate the dairy industry to ensure that operations do not harm public health or the environment. Unfortunately, inspections often involve nothing more than cursory visits by WSDA staff. If problems are found, dairy owners receive only a slap on the wrist, at best.

The hope is that this court victory against CAFO manure handling and pollution – little mentioned in the media – will help set a precedent toward better practices, regulation and enforcement of the CAFO industry. Reddout acknowledges that this court victory is one small step, albeit an important one, that shows that CAFOs aren’t above the law and puts them on notice for pollution practices, a particularly big deal for the economically (and thus politically) strong Yakima Valley dairy industry. Based on the compelling evidence of agricultural water contamination in the Lower Yakima Valley, and bolstered by the recent ruling, the EPA selected the area for inclusion in a study monitoring nitrate pollution in groundwater. Reddout expects the EPA report to be released in late Spring 2012.
