The utilities’ own data shows that heavy metals are leaking into ground and surface waters. These contaminants, such as arsenic, radium, mercury, chromium and others, threaten water quality and wildlife, and constitute illegal contamination of state waters.
What are the 3 most common contaminants in water?
The most common drinking water contaminants are microorganisms, nitrate, and arsenic. Water quality monitoring has improved over the past five years. Bacteria, viruses, and protozoa (such as Giardia lamblia and Cryptosporidium) are drinking water contaminants that can rapidly cause widespread and serious illnesses.
What is the main contaminant in river water?
Nutrient pollution, which includes nitrates and phosphates, is the leading type of contamination in these freshwater sources. While plants and animals need these nutrients to grow, they have become a major pollutant due to farm waste and fertilizer runoff.

What are the 4 types of contamination?
There are four main types of contamination: chemical, microbial, physical, and allergenic. All food is at risk of contamination from these four types. This is why food handlers have a legal responsibility to ensure that the food they prepare is free from these contaminants and safe for the consumer.

What are the main causes of river pollution?
Causes of water pollution
- spills or leaks from oil and chemical containers.
- trade effluent going into surface water drains instead of foul water drains, or straight into watercourses.
- removing too much water from surface waters and groundwater.
- run-off containing fertilisers and pesticides from farming into surface waters.
Can you swim in the Alabama River?

What are the 4 different types of impurities present in natural water?
These impurities include dust, fine sand, clay, dirt, and biological contaminants. Pure water is tasteless, colorless and odorless, but water from rainfall, streams and wells is known to harbor harsh chemicals and elements, including acid and metallic rust elements.
What are the three categories of contaminants?
Here are the three types of contaminants: Biological: Examples include bacteria, viruses, parasites, fungi, and toxins from plants, mushrooms, and seafood. Physical: Examples include foreign objects such as dirt, broken glass, metal staples, and bones. Chemical: Examples include cleaners, sanitizers, and polishes.
What are the three different types of contamination How are these caused?
There are three ways that food can be contaminated:
- biological hazards (microorganisms) including bacteria, fungi, yeasts, mould and viruses.
- chemical hazards. including cleaning chemicals or foods with naturally occurring toxins, such as green potatoes.
- physical hazards.
