Toxins in the Water II

(source)

Welcome to the second week of toxins in water!  If you missed the first week, we talked about the types of contaminants that can be in water.

This week we are going to start to discuss the toxins that may be in our water.

The possible contaminants that were mentioned last week include:

  • Insecticides and herbicides
  • Petroleum hydrocarbons, including fuels
  • Polychlorinated biphenyl (PCBs)
  • Chemical compounds found in personal hygiene and cosmetic products (medicine)
  • Ammonia from food processing waste
  • Fertilizers containing nitrates and phosphates

This week we are going to start to talk about insecticides and pesticides.

Are these toxins really in my water?

To find out if these toxins are in your water, visit EWG’s site.

Why are these toxins in my water?

There are a few major routes through which insecticides and pesticides reach the water:

  • they may drift outside of the intended area when it is sprayed
  • they may percolate, or leach, through the soil
  • they may be carried to the water as runoff
  • they may be spilled (source)
  • they may be carried to water by eroding soil (source)

In streams sampled by NAWQA, at least one pesticide or degradate was detected more than 90 percent of the time in water, in more than 80 percent of fish samples, and in more than 50 percent of bed-sediment samples collected during 1992– 2001 (source)

    Yes I do worry about it. I drink a lot of water which I filter from the tap but I wonder how much of the nasty stuff really gets filtered out.
