Surface water sources like rivers and lakes can be exposed to flood waters, storm runoff, pesticides, fertilizers, acid rain, and industrial waste, contaminating the water. Groundwater sources from wells can be contaminated by pathogens, leaking underground storage tanks, and agricultural chemicals. Drinking contaminated water can cause illnesses ranging from vomiting and skin rashes to cancer, organ damage, and birth defects. Major contaminant groups include microbial pathogens, organic and inorganic chemicals, and radioactive elements.

1. WATER CONTAMINANTS

2. Surface Water Source (RIVERS/
LAKE)
 The water can be exposed to
flood water, (it carries ihi,
jebs, dura, plema eww! etc.)
storm water run offs,
pesticide and fertilizer runoff,
acid rain, and industrial waste.
Potential Water Contaminants

3. Groundwater Source
 Public wells/pumps and private wells, the
water is not exposed to aerobic bacteria.
 It can be contaminated by pathogens, leaking
underground storage tanks, agriculture
fertilizers and pesticides etc.
Potential Water Contaminants

5. Dizzy
Vomiting
Nauseated
Skin rashes
Drinking Contaminated Water
Cancer
Damage to immune
system and NS, kidney,
liver damage b
Birth defects

6. Microbial Pathogens
 Diseases-producing
microorganisms (e.g.,
bacteria, viruses, and
parasites.
 It can cause gastroenteritis,
dysentery, diarrhea,
abdominal cramps and gas.

7. Organics or Organic
Chemicals
 Pesticides(herbicides,
insecticides, and
fungicides)
 Cancer, disorders of NS and
Reproductive System, liver
and kidney damage.
