2006 WATER QUALITY REPORT

FOR

ALGONA MUNICIPAL UTILITIES

This report contains important information regarding the water quality in our water system. The source of our water is groundwater. Our groundwater is drawn from the Cretaceous (Dakota Sandstone) aquifer. Our water quality testing shows the following results:

CONTAMINANT	MCLG		MCL	DETECTED LEVEL	DATE SAMPLED	RANGE OF DETECTION	VIOLATION	SOURCE
Copper (ppm)		1.3	AL =1.3	0.48 1 exceeded the AL	8/24/04	ND – 1.5	No	Corrosion of household plumbing systems; Erosion of natural deposits
Lead (ppb)	0		AL =15	4	8/24/04	ND – 9	No	Corrosion of household plumbing systems; erosion of natural deposits
TTHM (ppb) [Total trihalomethanes]		N/A	80	62	7/10/06		No	By-products of drinking water disinfection
Alpha emitters (pCi/L)	0		15	5.6	10/14/03		No	Erosion of natural deposits
Combined radium (pCi/L)	0		5	2.9	10/30/06		No	Erosion of natural deposits
Barium (ppm)	2		2	0.09	7/26/04		No	Discharge of drilling wastes; Discharge from metal refineries; Erosion of natural deposits
Fluoride (ppm)	4		4	1.36	3/17/06	0.94 – 1.36	No	Water additive which promotes strong teeth; Erosion of natural deposits; Discharge from fertilizer and aluminum factories
Sodium (ppm)	N/A		N/A	77	7/26/04		No	Erosion of natural deposits; Added to water during treatment process
Nitrate [as N] (ppm)	10		10	0.3	1/1/06 12/31/06	0.3	No	Runoff from fertilizer use; Leaching from septic tanks, sewage; Erosion of natural deposits
Chlorine (ppm)		MRDLG =4.0	MRDL=4.0	0.89		0.60 -1.62	No	Water additive used to control microbes

Note: Contaminants with dates indicate results from the most recent testing done in accordance with regulations.

DEFINITIONS

· Maximum Contaminant Level (MCL) – The highest level of a contaminant that is allowed in drinking water. MCLs are set as close to the MCLGs as feasible using the best available treatment technology.

· Maximum Contaminant Level Goal (MCLG) -- The level of a contaminant in drinking water below which there is no known or expected risk to health. MCLGs allow for a margin of safety.

· ppb -- parts per billion.

· ppm -- parts per million.

· pCi/L – picocuries per liter

· N/A – Not applicable

· ND -- Not detected

· Treatment Technique (TT) – A required process intended to reduce the level of a contaminant in drinking water.

· Action Level ( AL ) – The concentration of a contaminant which, if exceeded, triggers treatment or other requirements which a water system must follow.

· Maximum Residual Disinfectant Level Goal (MRDLG) - 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.

· Maximum Residual Disinfectant Level (MRDL) - The highest level of a disinfectant allowed in drinking water. There is convincing evidence that addition of a disinfectant is necessary for control of microbial contaminants.

GENERAL INFORMATION

Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants. The presence of contaminants does not necessarily indicate that water posed a health risk. More information about contaminants or potential health effects can be obtained by calling the Environmental Protection Agency’s Safe Drinking Water Hotline (800-426-4791).

Some people may be more vulnerable to contaminants in drinking water than the general population. Immuno-compromised persons such as persons with cancer undergoing chemotherapy, persons who have undergone organ transplants, people with HIV/AIDS or other immune system disorders, some elderly, and infants can be particularly at risk from infections. These people should seek advice about drinking water from their health care providers. EPA/CDC guidelines on appropriate means to lessen the risk of infection by Cryptosporidium and other microbial contaminants are available from the Safe Drinking Water Hotline (800-426-4791).

SOURCE WATER ASSESSMENT INFORMATION

The source of water for the City of Algona is groundwater drawn from 4 wells from the Cretaceous (Dakota Sandstone) aquifer. The Cretaceous (Dakota Sandstone) aquifer was determined to be susceptible to contamination because the characteristics of the aquifer and overlying materials allow contaminants to move through the aquifer fairly quickly. The City of Algona wells will be susceptible to activities such as leaking underground storage tanks, industrial sites, and wastewater discharges. A detailed evaluation of your source water was completed by the IDNR, and is available from Algona Municipal Utilities at (515) 295-3584.

CONTACT INFORMATION

For questions regarding this information, please contact John Bilsten , General Manager, at (515) 295-3584 during the following hours: Monday – Friday, 8:00 a.m – 4:30 p.m.

Decisions regarding the water system are made at the Algona Municipal Utilities Board of Trustees meetings held twice a month at the Algona Municipal Utilities Business Office meeting room. For information regarding the Board of Trustees meeting times and dates, call (515) 295-3584. The meetings are open to the public at the following address:
