Organics

Organic contaminants occur naturally or result from urban stormwater runoff, industrial or domestic wastewater discharge, oil and gas production, mining, or farming..

NOTES:
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.
Xylenes, Total*: Some people who drink water containing xylenes in excess of the MCL over many years could experience damage to their nervous system.

Disinfection Byproducts

Byproducts of the ozination, oxidation, or chlorination of drinking water prior to use.
