You should stop eating vegetables then because it will surprise you just how much this happens! LOL Actually many large cities do this, Calgary being one that we run a soil sampling program for. The waste is processed (usually in a digester/aeration combo at least) and the final effulent/sludge is put back onto the land, they're not pumping straight poop/sewage onto the ground.... LOL The Hutterite colonies also spray "Black Rain" from their pig lagoons onto the soil and it acts as a great fertilizer. Placing the effluent on land allows further degradation time, UV from the sun will kill microbes, the plants only absorb the nutrients they need and do not absorb "human waste". One of the important reasons to wash your veggies though.... haha. Up until a few years ago, the City of Victoria piped raw sewage out into the ocean, guess where the salmon on the kitchen table came from..... heehee
The issue of Sask and the amount of fertilizer is related to the nitrogen in the water. Nitrogen and nitrate in the water causes "blue baby"syndrome, a blood disorder where nitrogen inhibits the ability of hemoglobin to carry oxygen. Yes nitrogen is a component of manure but this is augmented by far too many commercial over-applications of fertilizer. Most of the underground aquifers in Sask do not flow anywhere near as fast as a stream in BC, so the ability of nitrate to accumulate in the aquifer is much higher.
LOL...and I hate to break bad news to you...but no one is "upstream" of any potential for beaver fever, fecal contamination etc. Animals will defecate in a stream just as readily as humans and run off carries all the issues from the forest floor right into the stream. Many times people who live "off the grid" from treated water supplies have more water quality issues than those in urban centers usually due to lack of water treatment. Turbidity, sedimentation, etc. Often times the water tastes better fresh in a mountain stream due to lack of processing (pipes, pumps and chemicals) but does not mean its any "cleaner". If rural users are on wells, often times there is a lot of bacterial growth in the well unless it is routinely shocked. I grew up on rural BC water in the kootenays, and after I got into the environmental industry and did some water testing on our source, I made my parents get a water treatment system......
Anyway, good to see some of the caribou survived to start a new herd!
If I can digest all of that I'll be a little more up to speed on the idiosyncrasies of environment behaviour regarding the spraying of human sewage onto fields. Thanks for the information. I'm not totally out to lunch but a lot of those things are surprising. With regards to the water, I am happy that I am at the top of the chain other than a few animals (a moose, beaver, bear, etc. here and there). It is much better than using drinking water in North Battleford, Medicine Hat, and Saskatoon.
The caribou will survive to become food for a predator. Few will die of old age.
