Sources Of Drinking Water in Chester, Pennsylvania

Where does Chester get its water from? The water in Chester, PA is treated and pumped to you from the CWA Octoraro Treatment Plant. In 2009, this facility produced an average of 31 million gallons of drinking water each day. The water treated at the Octoraro Treatment Plant comes Reservoir on the Octoraro Creek, and the Conowingo Pool of the Susquehanna River. Both of these sources are in the Susquehanna River Basin. Fluoride (A known neurotoxin) is also added to the water to prevent tooth decay. Is  Chester's water safe to drink?

Contaminants Found in Chester's Water Supply

(Detected above health guidelines)

Atrazine

Atrazine is a herbicide commonly detected in drinking water that comes from cornfield and other agricultural runoff. It is a hormone disrupter that harms the male and female reproductive systems of people and wildlife.

Bromodichloromethane

Bromodichloromethane, one of the total trihalomethanes (TTHMs), is formed when chlorine or other disinfectants are used to treat drinking water. Bromodichloromethane and other disinfection byproducts increase the risk of cancer and may cause problems during pregnancy.

Chloroform

Chloroform, one of the total trihalomethanes (TTHMs), is formed when chlorine or other disinfectants are used to treat drinking water. Chloroform and other disinfection byproducts increase the risk of cancer and may cause problems during pregnancy.

Chromium (hexavalent)

Chromium (hexavalent) is a carcinogen that commonly contaminates American drinking water. Chromium (hexavalent) in drinking water may be due to industrial pollution or natural occurrences in mineral deposits and groundwater.

Dibromochloromethane

Dibromochloromethane, one of the total trihalomethanes (TTHMs), is formed when chlorine or other disinfectants are used to treat drinking water.

Hormones 

This utility detected Testosterone. Hormones in drinking water come from human and animal wastewater discharged into drinking water sources. Conventional drinking water treatment does not remove hormones.

Radiological contaminants 

Radiological contaminants leach into water from certain minerals and from mining. This utility detected Radium, combined (-226 & -228).

Total trihalomethanes (TTHMs)

Trihalomethanes are cancer-causing contaminants that form during water treatment with chlorine and other disinfectants. The total trihalomethanes group includes four chemicals: chloroform, bromodichloromethane, dibromochloromethane and bromoform.

Fluoride

Fluoride occurs naturally in surface and groundwater and is also added to drinking water by many water systems. The fluoride that is added to water is not the naturally occurring kind, the main chemicals used to fluoridate drinking water are known as “silicofluorides” (i.e., hydrofluorosilicic acid and sodium fluorosilicate). Silicofluorides are not pharmaceutical-grade fluoride products; they are unprocessed industrial by-products of the phosphate fertilizer industry (Gross!). Since these silicofluorides undergo no purification procedures, they can contain elevated levels of arsenic — moreso than any other water treatment chemical. In addition, recent research suggests that the addition of silicofluorides to water is a risk factor for elevated lead exposure, particularly among residents who live in homes with old pipes.

Potential Health Effects of Consuming These Contaminants

Health risks of atrazine in excess of health guideline 

Cancer: The health guideline of 0.1 ppb for atrazine was defined by EWG based on epidemiological studies of human exposure to atrazine in drinking water.. This health guideline protects against harm to the developing fetus, harm to the reproductive system and hormone disruption.

Health risks of bromodichloromethane in excess of health guideline

Cancer: The health guideline of 0.4 ppb for bromodichloromethane was defined by the California Office of Environmental Health Hazard Assessment as a one-in-a-million lifetime risk of cancer. Values greater than one-in-a-million cancer risk level can result in increased cancer cases above one in a million people.

Health risks of chloroform in excess of health guideline

Cancer: The health guideline of 1 ppb for chloroform was defined by the California Office of Environmental Health Hazard Assessment as a one-in-a-million lifetime risk of cancer. Values greater than one-in-a-million cancer risk level can result in increased cancer cases above one in a million people.

Health risks of chromium (hexavalent) in excess of health guideline

Cancer: The health guideline of 0.02 ppb for chromium (hexavalent) was defined by the California Office of Environmental Health Hazard Assessment as a public health goal, the level of a drinking water contaminant that does not pose a significant health risk. This health guideline protects against cancer.

Health risks of dibromochloromethane  in excess of health guidelines

Cancer & Birth Defects: Dibromochloromethane and other disinfection byproducts increase the risk of cancer and may cause problems during pregnancy.

Health risks of hormones in excess of health guideline

Endocrine Disruption: Hormones in drinking water come from human and animal wastewater discharged into drinking water sources. Conventional drinking water treatment does not remove hormones.

Health risks of trihalomethanes in excess of health guideline

Cancer: The health guideline of 0.8 ppb for trihalomethanes was defined by the California Office of Environmental Health Hazard Assessment as a draft public health goal, the level of drinking water contaminant that does not pose a significant health risk. This health guideline protects against cancer.

Health risks of radiological contaminants in excess of health guidelines

Birth defects: Drinking water contamination with radioactive substances increases the risk of cancer and may harm fetal development.
