Blue Hole Spring – Detailed Results

Blue Hole Spring flows from the streambank into Blue Hole Creek. It’s just downstream from the kiosk and swimming hole on Blue Hole Road.

GPS Coordinates: 39.972525, -79.298164

Please read the results and descriptions of the parameters before drinking. Keep in mind that our testing shows a snapshot of water conditions on the day we took the samples. Water quality is constantly changing, so use your best judgement!

We will continue to update this page as we do quarterly water sampling at these Roadside Spring locations. If you have any questions, please email Chantelle@mtwatershed.com or call 724-455-4200 ext. 1#.

Comments: Unfortunately drinking water standards for Spring that feeds into Blue Hole Creek are still shaky due to potential lead contamination The surface waters of Blue Hole Creek has tested positive for lead containment and while the spring associated with Blue Hole is fed by ground water and hasn't shown trace amount of Lead it is still at risk for contamination. Recent Spring results have not indicated lead being present within the spring, however due to the volatile nature of water chemistry we advise to Exercise Extreme Caution and to refrain from utilizing the associated spring until further notice.

Spring Parameter Explanations

These parameters were chosen since they are some of the common contaminants in waters of our local area. Our sample results are compared to the EPA’s Primary and Secondary Standards (some parameters do not have an EPA standard) to determine “red”—unsafe, “green”—safe status. These are strict safety standards, and we provide explanations of each parameter so you can properly use your judgement when getting water from these springs.

Acidity

Water’s resistance to upward changes in pH—becoming more alkaline.

Alkilinity

Water’s resistance to downward changes in pH—becoming more acidic.

pH

Measured on a scale of 0-14, this number tells how acidic or alkaline water is. pH less than 7 is acidic, pH of 7 is neutral, pH higher than 7 is alkaline. The ideal range for drinking water is between 6.5-8.5

TSS (Total Suspended Solids)

 

This is the concentration of solid particles floating around in the water. It’s measured in milligrams of suspended solids per liter of water.

 

Specific Conductance

This is a measure of water’s ability to conduct electricity. A higher or lower conductivity correlates to a higher or lower amount of dissolved minerals and metals in the water like calcium or iron. The more minerals and/or metals that are dissolved within the water, the higher the specific conductivity.

 Sulfate

 

This is the concentration of sulfate in water measured in milligrams per liter of water. It’s typically accompanied by a rotten egg odor or salty taste in high concentrations. The maximum containment level (MCL) for sulfate is 500mg/L

 

Aluminum

 

This is the concentration of aluminum in water measured in milligrams per liter (mg/L) of water. Aluminum contamination is usually invisible, and any water with aluminum concentration greater than 0.2 mg/L should not be drank as aluminum poisoning can mimic dementia and impact organ functioning.

 

Iron

 

This is the concentration of iron in water measured in milligrams per liter of water. Low levels of Iron in drinking water is mostly harmless, but there has been some suggestion that drinking water with excessive iron can affect kidney cells. Iron can make water have a metallic taste and results in orange staining on surfaces. Excessive Iron in water can also support the formation "Iron bacteria" that can create an environment for Coliform Bacteria to stick to. The Secondary Containment MCL standard for iron in drinking water is 0.3mg/L 

E. Coli

 

This is the number of colonies of E. Coli bacteria per 100 milliliters of water. We do not recommend drinking water with any measurable amount of E. Coli since that points to fecal contamination (sewage, manure, wild animal waste etc.) which can results in extreme sickness.

 

Total Coliform

 

This is the number of total coliform bacteria colonies per 100 milliliters (MPN/100mL) of water. Coliforms are a common type of bacteria present in water and soil that are mostly harmless, but some can cause mild to severe illness (like E. coli). EPA drinking waters standards are 0 MPN/100mL, but given how widespread and numerous these bacteria are, it’s practically impossible for water sources to meet that standard unless ran through some kind of treatment. Naturally, these roadside springs will have some measurable level of total coliform, but use caution.

 

Manganese

 

This is the concentration of manganese in water measured in milligrams per liter (mg/L) of water. In concentrations above 0.05 mg/L it can cause water to have a metallic taste and leave black stains on surfaces. Concentrations much greater than 0.05 mg/L can cause neurological problems. Sources vary on what this dangerous level is, but it’s sighted as anywhere from 0.1 mg/L for infant toxicity to 0.3 mg/L for toxicity to adults.
