Hardness Of Water

State water quality results show Bishop Harbor is OK

MANATEE -- State officials released a new set of water quality test results Friday, concluding that “there are no water quality concerns for metals and other parameters in Bishop Harbor.”

But the results also showed that levels of cadmium, a highly toxic heavy metal, had actually increased near the former Piney Point phosphate plant, now owned by HRK Holdings, LLC. And levels of phosphorus and nitrogen continued to be “very high,” according to an attorney who specializes in environmental cases.

HRK officials first reported problems at their facility May 11. They determined that water was leaking from the site because of ruptures in a plastic liner that covers the floor of the former gypsum stacks, where dredge material from Port Manatee has been handled.

On May 29, state officials allowed emergency discharges to ensure the structural integrity of the site. Millions of gallons were discharged per day for weeks. The Florida Department of Environmental Protection tested water samples collected in the area May 30 and again June 9.

Much of the water that leaked from the site drained downhill to Bishop Harbor, which is part of the Terra Ceia Aquatic Buffer Preserve.

“Of particular note, the results show that cadmium, which was detected in the discharge to the Buckeye Road ditch, is more than 10 times below the cadmium marine water quality standard that applies to this system,” said a DEP summary of the most recent data.

The testing found cadmium at one site in the harbor at a concentration of 0.73 micrograms per liter, well below the state saltwater standard of 8.8 micrograms per liter, DEP officials said.

But the amount of cadmium DEP discovered at an outfall that drained into a ditch alongside Buckeye Road was higher than the sample taken May 30, the results showed.

The latest results showed 2.4 micrograms per liter, compared to 2.0 micrograms per liter previously, both well above the freshwater standard of .22 micrograms per liter.

Cadmium levels are evaluated in part in connection with the hardness of the water, and seawater by its nature is a hardwater system, according to John Coates, deputy director for DEP’s Division of Water Resources Management.

He contended that would be a mitigating factor, since the discharge from the site was mostly seawater.

Environmental attorney David Guest agreed, but said of the findings: “The problem is the area around the outfall is gravely polluted; the question is, ‘How big an area is being seriously contaminated?’ and it sounds like a pretty big area.

Remove Hardness of Water for Your Whole House « eXplorations ...

Water is an essential compound that all living things need to survive. For this article we will classify water into these two different types; soft water and hard water. Soft water is treated water where sodium is used to filter out impurities, while hard water is made up of dissolved minerals which include charged ions like magnesium and calcium.

Why do we have to remove water hardness?

Hard water can be present anywhere that is rich in minerals like calcium, copper, iron and other heavier metals naturally sourced in rocks and soil. In our household we use water for cooking, cleaning, washing, and most importantly for drinking. Prior to heavy industry polluting our rivers, streams, lakes and our own carelessness with our natural reserves, drinking water from the faucet was considered safe however as the years passed by you can no longer be sure that the water entering our homes is entirely free from harmful heavy metals.

Chlorine has now been a significant portion of municipal water strategy for nearly a century. About 98% of municipal water treatment facilities now use chlorine as being the primary disinfectant and the majority of U.S. residents receive chlorinated drinking water through their home faucets. Chlorine is listed as a known poison. Chlorinated water has been linked to the aggravation and cause of respiratory diseases like asthma because it vaporizes much quicker than water itself. We recommend to the household before installing water filtration equipment to test and check the impurities that are present in your household water and the level of hardness. Getting a free water test from your Culligan man is possibly the quickest and reliable method for most homeowners.Some municipalities will publish test results however these summaries may well not show you how to know very well what impurities make water hard. To remove hardness of water in Montgomery County it is best to understand the properties of those particles that cause hard water. Its not whole house home water filtration systems are meant to remove all impurities. These whole house units are produced as a point-of-entry system that filters water directly as it enters a home plumbing system from a municipal or private well water source.

Point of use systems are made to filter household water just at the tap. However for effective results, you must choose the best water filter for hard water and in some cases this may be a mixture of the whole house water filter and also a counter top or under the counter model depending upon the amounts of lead, iron, chlorine and biological impurities.
