Water Quality Report

Hanapepe-Eleele

Results:

The following tables lists all the drinking water contaminants that were found in 2000. Unless otherwise noted, the data presented in the following tables are from testing done January 1 - December 31, 2000.

The State requires us to monitor for certain contaminants less than once per year because the concentrations of these contaminants are not expected to vary from year to year. Thus, some of the data, though representative of the water quality, is more than one year old.

Terms and abbreviations used below:

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

• 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.

• Action Level (AL): the concentration of a contaminant which, when exceeded, triggers treatment or other requirements which a water system must follow.

• n/a: not applicable, nd: not detectable at testing limit, ppm: parts per million or milligrams per liter (corresponds to one penny in $10,000), ppb: parts per billion or micrograms per liter (corresponds to one penny in $10,000,000), pCi/l: picocuries per liter(a measure of radiation), mrem/year: millirems per year (a measure of radiation exposure).

• What is the pH of my Water?

The pH of your water in the Hanapepe & Eleele area can range from 7.5 to 7.8.

• What is the hardness of my water?

The hardness of your water can range between 21 to 68 ppm.

Microbiological Contaminants:

Substance	Highest level allowed (MCL)	EPA MCLG	Highest monthly # of positive samples	Date	Violation	Source of Contaminant
None detected

Inorganic Contaminants:

Substance	Highest level allowed (MCL)	EPA MCLG	Level Detected	Detection Range	Date	Violation	Source of Contaminant
Barium	2	2	0.003	0-0.003	1999& 2000	No	Discharge from drilling wastes;metal refineries;erosion of natural deposits.
Chromium (ppb)	100	100	11.0	0-11.0	1999& 2000	No	Discharge from steel & pulp mills; erosion of natural deposits
Nitrate (ppm)	10	10	5.2	0.42-5.4	2000	No	Runoff from fertilizer use; leaching from septic tanks, sewage; erosion of natural deposits
Flouride (ppm)	1.4	4	0.36	0-0.36	2000	No	Erosion of natural deposits

Nitrate: Nitrate in the drinking water at levels above 10 ppm is a health risk for infants of less than six months of age. High nitrate levels in drinking water can cause blue baby syndrome. Nitrate levels may rise quickly for short periods of time because of rainfall or agricultural activity. If you are caring for an infant, you should ask for advice from your health care provider.

Organic Contaminants:

Substance	Highest level allowed (MCL)	EPA MCLG	Level Detected	Detection Range	Date	Violation	Source of Contaminant
None Detected

Lead and Copper Rule Compliance

Substance	Action level	MCLG	Level Detected	# of sites sampled	# of sites found above the AL	Source of Contaminant
Lead (ppb)	15	0	<5	12	0	Corrosion of household plumbing systems; erosion of natural deposits
Copper (ppm)	1.3	1.3	0.10	12	0	Corrosion of household plumbing systems; erosion of natural deposits; leaching from wood preservatives

The Hanapepe-Eleele system is in compliance with Lead and Copper Rule requirements and is on a reduced monitoring schedule. Samples for lead and copper will be taken and analyzed ever three years.

Radioactive Contaminants:

Substance	Highest level allowed (MCL)	EPA MCLG	Level Detected	Detection Range	Date	Violation	Source of Contaminant
None Detected

Information on Violations of National Primary Drinking Water Regulations

There has been no system violations nor individual sampling deficiencies in testing your area’s water for chemical, bacteria, and heavy metal contaminations.
