Heavy Metals
Heavy Metals can be toxic to humans and animals at specific levels. Currently many initiatives are being made to reduce heavy metals in the Animas River.

Bonita Peak Mining District
The Bonita Peak Mining District site consists of 48 historic mines or
mining-related sources where ongoing releases of metal-laden water and
sediments are occurring within Mineral Creek, Cement Creek and the Upper
Animas. Near Silverton, Colorado, these drainages join to form the
Animas River, which is used for drinking water, recreation and
agricultural purposes. Website: https://cumulis.epa.gov/supercpad/cursites/csitinfo.cfm?id=0802497

Good Samaritan Legislation
The Mission
There are tens of thousands of abandoned mines in the U.S. Many of these mines emit acid mine drainage laced with heavy metals which can contaminate the water quality of rivers and streams. In a number of instances, Good Samaritans are willing to conduct mine reclamation at these sites if they have environmental liability protection from the Clean Water Act (and perhaps the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA). This liability protection which could encourage mine cleanups can only occur through federal legislation. Website: http://goodsamaritaninfo.org/
Nutrient Loading
"Nutrient pollution is the process where too many nutrients, mainly nitrogen and phosphorus, are added to bodies of water and can act like fertilizer, causing excessive growth of algae." : National Oceanic and Atmospheric Administration. ( http://oceanservice.noaa.gov/facts/nutpollution.html )

Excess nutrients or nutrient pollution is also called Eutrophication. Excessive amounts of nutrients can lead to low levels of Dissolved Oxygen which can cause fish kills, or an Increase in Algal growth which causes a decrease in available sunlight.

Nutrients can come from many different sources, such as: natural processes or human processes; such as ferlizers, sewage, or animal waste.

Sedimentation
Sedimentation is the process by which the products of erosion (i.e. rocks, sand, and/or clay) settle out and deposit onto the bottom of a water body.
Some materials in the San Juan Mountains erode more easily than others.  Easily eroded materials include shale, sandstone, and limestone.

Sedimentation can occur on land or in water. It can cause damage of land and cause safety issues on roads.
Sedimentation can cause issues with capacity in rivers, lakes, ditches, canals, etc. Filling them up and displacing water or overflowing onto roads.

Sedimentation is often linked to suspended solids and high turbidity that can affect aquatic life.

Bacteria

Bacteria are one celled organisms that are found everywhere. Some bacteria are harmful while others are beneficial (such as fermentation in wine).
E.coli is a type of bacteria used as an indicator of the potential for the presence of pathogens in waterbodies. E.coli is commonly found in the intestinal track of humans and other animals. However there are some strains of E.coli that can cause serious infections.

Potential sources of E. coli and other bacterial contamination include waste from wildlife, livestock and humans.

Riparian Buffer

"Riparian Buffers are vegetation left along the banks of a stream or river that that protect water resources from pollution running off the land, stabilize banks and provide habitat for fish and wildlife.

Improving Riparian Buffers can increase water quality and prevent erosion.
One way to increase a riparian buffer is by planting native plants, like willows, cottonwoods and buffaloberry..
