Arsenic Contaminated Groundwater Treatment

Providing quality environmental remediation systems & remediation services including arsenic removal in Florida since 1991.


Arsenic Contaminated Groundwater Treatment

CROY Environmental has been providing quality environmental remediation systems on contaminated jobsites all of the South Eastern United States since 1991.  We invented Dual Phase extraction and created a line of dual phase recovery pumps which separate the liquid and vapor for site requiring polishing of vapors as well as the effluent water.

CROY also has vessels for a variety of absorption treatment methods.  Gasoline stations with naphthalene or leaded gasoline contamination were one of the most common during the State of Florida funded underground storage tank replacement project which ended in the mid 2000’s.  For approximately 20 years CROY’s absorption treatment vessels were mainly used all across the state of Florida on gasoline stations.  Filled with Carbon,  these bad boys would handle a GPM upwards of 1000 gallons per minute (GPM) of leaded, or Diesel Fuel contaminated groundwater.

Since then,  the underground storage tank project in the State of Florida has come to an end.  Most all of Florida’s gas stations have replaced their tanks with the new double lined wall tanks and those that haven’t have had them removed, or are in process of still having them removed altogether.  

One of CROY’s most successful absorption treatment project types since the underground storage tank projects has been the removal of arsenic contamination from previous golf courses.  With the need for more housing in the State of Florida,  developers have had to look to areas within established communities to build new communities.  One successful resource for them has been failing golf courses.  Golf courses being redeveloped into residential and retail is a hot market here in Florida.  Most golf courses are located within the boundaries of an already thriving city.  These thriving cities have no options left for large acreage development.  This is why redevelopment of these failing golf courses has been such a success.  One common contaminate found during the redevelopment of these golf courses is Arsenic.

CROY’S Arsenic Contaminated Groundwater Treatment Systems feature absorbing media known as  Activated Alumina.

Activated alumina is aluminum oxide in the form of very porous spheres that are literally “tunneled” at the microscopic level. This makes them handy for a number of different jobs. For example, they can be used to treat groundwater contaminated with high levels of arsenic.

Activated alumina adsorbs chemicals. When a chemical is drawn into the pores of an activated alumina sphere, it actually bonds with the solid material. Once in, it won’t come out without considerable heating.  Because of this,  CROY uses Activated Alumina in all of our Arsenic Contaminated Groundwater Treatment Systems.  Activated Alumina is an efficient way to clean up the environment. It’s ability to bind with toxic substances means that these substances don’t leak back into the environment when disposed of.

An important feature of activated alumina is that it is very stable. It will bond with other substances without changing its own chemistry or form. And because it is so porous, its surface area is far greater than its weight, enabling it to adsorb a great deal.

There are many causes of Arsenic contamination.  Arsenic is a semi-metal element in the periodic table. It is odorless and tasteless. Arsenic occurs naturally in rocks and soil, water, air, and plants and animals. It can be further released into the environment through natural activities such as volcanic action, erosion of rocks and forest fires, or through human actions. Approximately 90 percent of industrial arsenic in the U.S. is currently used as a wood preservative, but arsenic is also used in paints, dyes, metals, drugs, soaps and semi-conductors. High arsenic levels can also come from certain fertilizers and animal feeding operations. Industry practices such as copper smelting, mining and coal burning also contribute to arsenic in our environment. * Higher levels of arsenic tend to be found more in ground water sources than in surface water sources (i.e., lakes and Rivers).  

Traces of arsenic can be found in most of Floridas older golf courses.  This makes redevelopment an issue. Especially when large amounts of arsenic is discovered.

CROY has the experience,  the knowledge,  and the equipment needed to handle any contaminated remediation project you may have.

Arsenic contamination, gasoline contamination, diesel contamination, chlorinated solvent contamination,  and jet fuel contamination are just a few of the contaminated CROY excels at.
