Dibromochloropropane (DBCP)
Some
people who drink water containing DBCP in excess of the MCL over
many years could experience reproductive problems and may have
an increased risk of getting cancer.
Di (2-Ethylhexyl) phthalate
Some
people who drink water containing di (2-ethylhexyl) phthalate in
excess of the MCL over many years may have problems with their
liver, or experience reproductive difficulties, and may have an
increased risk of getting cancer.
Dieldrin
No
health effects determined at this time.
Total Xylene*
Some
people who drink water containing xylenes in excess of the MCL
over many years could experience damage to their nervous system.

MRDL= Maximum residual disinfectant
level goal means the level of a drinking water disinfectant
below which there is no known or expected risk to health. MRDLGs
do not reflect the benefits of the use of disinfectants to
control microbial contaminants. Pyramid Peak tested for but did
not find cryptosporidium.
Possible Sources:
1-Naturally present
2-Water additive used to control microbes
3-Rocket propellent |
