Microbiological Contaminants

 

Total Coliform Bacteria - The presence of coliform bacteria indicates that other potentially harmful bacteria may be present. Wheeling Water's 2006 testing indicates 0% presence of coliform bacteria.

Inorganic Chemicals Inorganic chemicals, such as salts and metals, can be naturally-occurring or result from urban storm water runoff, industrial or domestic wastewater discharges, oil and gas production, mining and farming.

All inorganic chemicals analyzed were below detection level with the exception of:

Contaminant	Violation Y/N	LevelDetected	Units ofMeasure	MCLG		MCL	Likely Source Of Contamination
Microbiological
Turbidity	N	0.11 100% of Samples<0.3	NTU	0		TT	SoilRunoff
TOC	N	2.76	ppm	N/A		TT	Naturally present in the environment
Inorganic
Copper*	N	0.42	ppm	1.3		AL-1.3	Corrosion of household plumbing systems; erosion of natural deposits
Lead*	N	1.9	ppb	0		AL=15	Corrosion of household plumbing systems; erosion of natural deposits
Fluoride	N	1.00	ppm	4		4	Erosion of natural deposits; additive to water which promotes strong teeth; discharge from fertilizer and aluminum factories
Nitrate	N	1.83	ppm	10		10	Runoff from fertilizer use; leaching from septic tanks; sewage; erosion of natural deposits
* Copper and Lead samples were collected from 31 homes in our community water system on 8-09-2006. Only the 90th percentile is reported. None of the samples exceeded the Action Level.
Barium	N	N/D	ppm	2		2	Discharge of drilling waters; Discharge from metal refineries; Erosion of natural deposits
Selenium	N	N/D	ppm	50		50	Discharge from Petroleum  and metal refineries; Erosion of natural deposits; Discharge from mines
Radioactive
Combined Radium*	N	0.4 +/- 0.67	pCi/L	0		5	Erosion of natural deposits
Alpha Emitters*	N	0.7 +/- 0.4	pCi/L	0		15	Erosion of natural deposits
* Combined Radium + Alpha Emitters Results From 2003 * EPA Considers 50 pCi/L to be the level of concern for beta particles
Unregulated Contaminants
Sodium*	N	29.2	ppm	NE		20	Erosion of natural deposits
* Sodium is an unregulated contaminant. Anyone having a concern should contact his or her primary health care provider.
Disinfection and Disinfection Byproduct Contaminants

Chlorine	N	Yearly Avg. 1.7 Range 1.2--2.5	ppm	4		4	Water additive used to control microbes
Haloacetic Acids	N	Yearly Avg. 34.3 Range 26.0--41.3	ppb	N/A		60	INORGANIC By-product of drinking water chlorination

*This is not a regulated parameter. This information is included for those persons who are required to monitor their sodium.
Regulated Volatile Organic Chemicals Organic chemical contaminants, including synthetic and volatile organic chemicals, are bi-products of industrial process and petroleum production, and can also come from gas stations, urban storm water runoff and septic systems. Of the 21 regulated VOCs, all were non-detectable for the 2006 analysis.

THMs (Total trihalomethanes) are a byproduct of drinking water chlorination. The MCL is currently 80 ppb. Wheeling Water's THM average is 56.3 ppb and our range of detection was 50.3 ppb to 63.4 ppb.
HAA5s (Haloacetic acids) are a byproduct of drinking water chlorination. The MCL is currently 60 ppb. Wheeling Water's HAA5 average is 34.3 ppb with a range of 26.0 ppb to 41.3 ppb.
Regulated Synthetic Organic Chemicals Pesticides and herbicides may come from a variety of sources such as agriculture, urban storm water runoff and residential uses. Our analysis showed that all of these were non-detectable for 2006.
Giardia and Cryptosporidia Wheeling Water detections in tap water for Total Giardia Cysts and Cryptosporidium Oocysts were each less than 1 per 100 liters. Detections in the river water (prior to treatment) for Total Giardia Cysts and Cryptosporidium Oocysts were less than 2900 per 100 liters.
Lead and Copper Sites chosen by regulations were required to have the greatest possibility of having high levels of lead and copper. The Action Level is set at 15 ppb for lead. One site exceeded the Action Level at 30 ppb. The Action Level for copper is set at 1.3 ppm. All samples tested for copper were below the action level.
Radioactive Contaminants Radioactive contaminants may be naturally-occurring or the result of oil and gas production and mining activities. Wheeling Water's Gross Alpha activity was non-detectable.
	Turbidity, caused by soil runoff, is generally thought of as the cloudiness of water. Although turbidity has no health effects, at high levels it can impair the disinfection process. The highest monthly average for 2006 was 0.11 NTU and the lowest monthly average was 0.04 NTU. The yearly average was 0.06 NTU.
