Zinc

Zinc is considered an essential element in human and animal nutrition . IT can be naturally occurring , the most significant source being zinc ores : sphalerite (ZnS) and smithsonite (ZnC03). These compounds end up in water on locations where zinc ores are found.

It may come from industrial contamination such as wastewaters containing zinc stem from galvanic industries and battery production . Zinc compounds are applied for many different purposes including parchment production . Zinc oxide is a constituent of salves , paints and catalyzers, zinc vitriol is applied as a fertilizer, and zinc bacitracin is applied as a growth stimulant in animal husbandry. Zinc can also be the result of corrosion of fixtures mostly brass, of which zinc is a major component.

In concentrations over 5 mg/I, zinc produces an objectionable taste and may cause water to appear milky, or upon boiling, to seem to have a greasy surface scum. Cases of zinc poisoning have been reported from prolonged consumption of water at concentrations of 40 mg/I.

What Do The Results Mean? Is It Regulated?

The average zinc concentration in seawater is 0.6-5 ppb. Rivers generally contain between 5 and 10 ppb zinc. Algae contain 20-700 ppm, sea fish and shells contain 3-25 ppm, oysters contain 100-900 ppm and lobsters contain 7-50 ppm.

Zinc is regulated as a secondary contaminant under the Safe Drinking Water Act. This means it is regulated based upon the aesthetic effects it may produce . The EPA has established a secondary MCL of 5 mg/L. The World Health Organization stated a legal limit of 5 mg Zn2+/L.

How Can You Test For Zinc?

You can analyze for zinc using 3500-Zn B. Zincon Method, which is a Standard Method utilizing a colorimeter. This can be an accurate analysis for field measurements .Laboratories analyzing drinking water samples can utilize various methods including EPA method 200 .7 and 200 .8 which utilize an Inductively Coupled Plasma (ICP) or the Standards Method 31138 which uses Graphite Furnace.

Water Treatment Options

If the presence of zinc is due to corrosion, it is best to treat the source of the problem by using a soda ash feed. You can also successfully remove zinc using distillation or reverse osmosis.

"Never disappoints! I've had two water tests conducted on my home. During the most recent John shared his knowledge and expertise on not only the Well tank pump that was in serious need of replacement but also options for my water softener. I never felt pressured to commit to something I didn't need. They made sure I had all the information and let me make a decision based on what made sense for me. Great experience from first call to final product!"

"We are new to the area and new to well water. We have used Sanatoga twice now - for routine maintenance and a water softener install. Juan is always on time and very attentive. We feel fortunate we have someone who cares about our house as if it were his own and a company we can count on in the years to come.
Thank you for excellent service!"

I could not be more happy with the customer service and professionalism that they provide. I always get a cheerful and helpful person on the other end of the line when I call the office, and the technicians who installed our water treatment system were clean, professional and answered all of my questions. I can definitely recommend Sanatoga, 5 Stars."

 Trustindex verifies that the original source of the review is Google. Sanatoga Water has always been the best when it comes to service and addressing all of our water conditioning needs for softeners, neutralizers, and reverse osmosis filtration. They’re always on time, professional, no-pressure, and they take the time to answer any and all of my questions (in person and on the phone). This is the second home I’ve used them and will continue to rely on them! I can’t recommend them enough.
