Another Reason to Grow Your Own!

August 6th, 2009

My friend Shaun mentioned that while out running one day he spotted a truck spraying something on a local field.

He assumed it was liquid manure at first, which is common to see farmers spraying on their fields. A closer look revealed something interesting.

That truck reads, “Brown Township Malvern Sewer District”. A couple days later he noticed a new sign had been placed kind of behind a tree, down on one corner of the field.

Sewer Sludge is defined as: an unpleasant material whose the quantities increase each year. According to the Center for Food Safety, this is what’s going on:

Every time you flush your toilet or clean a paintbrush in your sink, you may be unwittingly contributing fertilizer used to grow the food in your pantry. Beginning in the early 1990s, millions of tons of potentially-toxic sewage sludge have been applied to millions of acres of America’s farmland as food crop fertilizer. Selling sewage sludge to farmers for use on cropland has been a favored government program for disposing of the unwanted byproducts from municipal waste water treatment plants. But sewage sludge is anything but the benign fertilizer the Environmental Protection Agency says it is.

Sewage sludge includes anything that is flushed, poured, or dumped into our nation’s waste water system–a vast, toxic mix of wastes collected from countless sources, from homes to chemical industries to hospitals. The sludge being spread on our crop fields is a dangerous stew of heavy metals, industrial compounds, viruses, bacteria, drug residues, and radioactive material. In fact, hundreds of people have fallen ill after being exposed to sewage sludge fertilizer–suffering such symptoms as respiratory distress, headaches, nausea, rashes, reproductive complications, cysts, and tumors.

So I googled Class B sewer sludge to see what we were dealing with and I found this sickening bit of information:

Sludge is classified as either Class A or Class B, depending on the type of treatment it has received. Class A sludge has benefited from both pretreatment and treatment at the wastewater facility. The pathogens in Class A biosolids cannot exceed certain levels set by the EPA. Standards for Class B sludge are less stringent, and their use is therefore more regulated. A landowner who wishes to use Class B sludge as an alternative to conventional fertilizers must apply to the Texas Commission on Environmental Quality to register his site. Among other items, the application requires information on the type of land, the amount of buffer zones, and the type of soil. The applicant must also provide information from the wastewater treatment facility on the type of pollutants and pathogens in the sludge, and calculations of nutrient needs for the crops. The use of Class B sludge on land has been criticized by the Center for Disease Control and the National Institute for Occupational Safety and Health. A landowner using Class A sludge does not have to register his land.

After searching a while for information I came across a few articles I though you might find interesting if you want to read more about the use of sewer sludge in agriculture.

* Here is a great article about sewer sludge.

* Another story about sewer sludge usage on hay that was fed to cows that resulted in their death, over at the Organic Consumers Association.

* Even the White House garden has been contaminated with sewer sludge.

* Bio-solids: by any other name, Sludge

* Sludge News: a website dedicated to information about and activism against the use of sewer sludge. Including a list of fertilizers sold at Hardware stores that contain sludge.

This is why I want to GROW MY OWN and keep as closed a system as possible in my gardens. I’ll put homegrown compost on my gardens thanks!

Did you know that sewer sludge was used in agriculture, particularly on the food we eat?

    Thank you very much for this eye-opening post. Yes, this is the perfect why we must grow our own vegies if we can.

    Wow!! That is incredible that is an acceptable practice. Definitely one reason we are buying farmers at are local farmer’s market and am trying to grow as much as I can, even going as far as guerilla gardening to avoid having to buy things that has been deemed okay by those who supposedly know better. . . .

    oh yuck. That’s gross. And disturbing. Very disturbing. Thanks so much for this post. Not something I’ve heard about.
    It upsets me to find that its being sold in commercially available compost. My soil is not so great and I’ve been purchasing compost from Lowes and Home Depot to supplement the homemade compost we’ve been making. Won’t be doing that any more. With just two of us we don’t have much to add to the compost pile and it grows very slowly. I guess I’ll be finding a more reliable source.
    (Yet another reason I’ll be considering raising chickens.)
    Thanks.

    Yeah. But I didn’t know you could actually use Class B type sludge for food crops. I have heard of it on flowers and landscaping.

      In this field they were growing wheat, they harvested the wheat and then started spraying with sludge. We’ll see what they grow next.

        What do you want to bet that the field is left fallow so the farmer can collect the subsidy for that (yes, there are subsidies for that) then plants a crop the year after that?

    BTW… this field is right next to a ditch, that runs into a creek, that runs into a larger creek, that people catch fish from. I think if I see anyone fishing there, I am going to stop and tell them to read the blog!

    That’s actually kind of terrifying. The thought of untreated biowaste being applied to fields is absolutely disgusting, unsafe, and all sorts of other negative adjectives. I can’t believe they’re allowed to do this, especially without some sort of better warning system. That sign is teeny tiny, and can’t even be read without getting super close to it, not to mention it doesn’t even explain what the sludge is.

    I’ve heard they use it for fruit trees but let’s hope they don’t use it for vegetables though.

    I knew that sewer sludge was used – my dad would talk about a large metropolitan area had their sludge turned into fertilizer that homeowners could buy…and would plants would end up volunteering in that area as a result…

    What concerns me most is the reference to “the amount of buffer zones” – wasn’t there a semi-recent article/blog post out there somewhere (Ethicurean?) that talked about the scorched earth policies major veggie growers are required to utilize in hopes of preventing food borne illness? Some of which included eliminating buffer zones and biodiversity? Imagine if these types of products were applied w/out those things?

    I knew about this but thought they only put it on crops that don’t directly go into human consumption. I just looked it up and it would appear they put it on human food crops here as well. That is pretty scary, it would be alright if it was just human excrement but it’s everything that goes down the pipes. The article I was reading about Ontario in particular said in 1996 they stopped them from dumping it into the great lakes so since then they have increased the rate at which it is used as fertilizer. Crazy world we live in.

    it makes me feel so good to know that as i basically live in the middle of a corn field. i’m so glad we don’t drink our well water…. i’ve always said i didn’t want to drink it not knowing what else was in there… little did i know! i’ll be keeping my eye on the fields for these signs…. so much for us living in such a “green” culture. my first thought upon reading this article reminded me of a certain church camp in kentucky that has surely been condemned sometime over the last 10 years… :)

      Oh yes, what a fun week that was with the 105 degree days, the Earth Ball, raw sewage running by the cafeteria, taking a shower with a hose, sleeping in the van, and who can forget that two-seater toilet (which of course provided the raw sewage that ran by the cafeteria)! Thanks for reminding me.

    Think of all the expired medications that get dumped down people’s toilets. Nasty!

    Thanks for opening my eyes. I’m so glad I didn’t fall for the TAGRO sales pitch at a garden club meeting. The guy was pushing it big time and all of the ladies were exclaiming how wonderful it sounded. I’d be heartbroken if I had actually put that stuff on my land without knowing it was sewer sludge.

    Renee, Tagro is a Class A biosolid, which is MUCH better than Class B sludge. Tagro has been in use since 1991, has won numerous awards, and I must say, in every garden I have grown with it, has produced an amazing quantity of produce both in Tacoma, and now in central WA where I have transported my leftover Tagro.

    As with most things, biosolids/sewer sludge is only as good as the integrity of the waste treatment people. While there are many things the City of Tacoma could stand to improve (like pothole repair), when it comes down to coming up with a safe, effective gardening amendment, that also helps keep sludge out of our already over-stressed Puget Sound waters, they hit it out of the park with Class A Tagro. And that’s why, come next spring, I’m borrowing a truck, heading over the pass and loading up with some more for my garden next year. :-)
