Treatment

 

ECUA has 32 wells distributed throughout its service area that pump water from the Sand-and-Gravel Aquifer. In general, ECUA customers receive water from the wells (two to five) located closest to their residence.  Each well is considered a separate treatment plant, where water quality parameters are closely monitored and adjusted to comply with operating standards.  Granular Activated Carbon (GAC) filters are installed on eleven (11) wells for iron or organic contamination removal.  Calcium Hydroxide (lime) is added for pH adjustment; Phosphoric Acid is added for corrosion control in the distribution system and Chlorine is added for disinfection.   Fluoride is added at select wells, as a source of fluoride treatment. 

The recharge area for ECUA wells is limited to the area of Escambia County, south of Cantonment. Because the Sand-and-Gravel Aquifer does not have a confining layer above it, virtually everything that falls on the ground has the potential to reach the main producing zone of the aquifer and affect the quality of our water supply. You can help prevent groundwater contamination by observing a few key guidelines:


• Recycle used motor oil by returning it to stores or garages that accept and recycle the oil;
• Follow label instructions when using and disposing of pesticides, paints, or other household chemicals;
• If you are an ECUA residential sanitation customer, take advantage of our once-per-month free collection of Household Hazardous Waste.  Learn more about this convenient service here.

 

Wellhead Protection


Wellhead protection programs help protect public groundwater supplies from contamination and prevent the need for costly water treatment. ECUA is well aware of this threat to the groundwater and over the years has worked with Escambia County and the City of Pensacola in strengthening their Wellhead Protection Ordinances.


The national Wellhead Protection Program was established by the 1986 Amendments to the Safe Drinking Water Act (SDWA). The SDWA Amendments require each state to develop a Comprehensive State Groundwater Protection Program and encourage local water systems to develop wellhead protection plans for their community water systems.


If you own a well, protecting the area around your wellhead is important to protecting your water supply.


You can help protect your well:

* Safely seal, store or dispose of animal waste, fuels, pesticides, fertilizers, paints, and other harmful products in accordance with local waste disposal   ordinances. These elements should never be located near a wellhead.

*Properly seal a well with a 50-foot-deep sanitary seal around the well casing to prevent contaminants from directly entering the groundwater basin.

*If you're a private well user, test your well water at least once each year for coliform bacteria and at least once every three years for the Routine Domestic Water Analysis. For more information, call a certified private lab.

* Develop wells only outside areas of potential contamination. Corrals, pastures, feedlots, drainage ways or underground storage tanks should never be located near a well.
