Water Treatment Compliance

Providing Products & Service to Help You Stay In Compliance

The Hawkins Water Treatment Group supplies products to customers in 18 states across much of the U.S.

Our driver/technician/salesperson is trained to help you find system solutions to ensure you stay in compliance with the EPA Lead and Copper Rule.

Lead and Copper Rule Requirements

Exposure to lead and copper may cause health problems so in 1991 the EPA published a regulation to control lead and copper in drinking water. This regulation is known as the Lead and Copper Rule.

If lead concentrations exceed an action level of 15 ppb or copper concentrations exceed an action level of 1.3 ppm in more than 10% of customer taps sampled, the system must undertake a number of additional actions to control corrosion.

Lead Corrosion Control

We supply the products that prevent lead from leaching into the water.  Lead could be in the plumbing or in the lead solder used in the system.  We can help you stay in compliance with EPA Lead and Copper regulations.

Lead in your water at elevated rates could have potentially harmful effects.  The goal of corrosion control programs is not only to reduce the corrosion of distribution mains but also to minimize the release of lead and copper from residential plumbing fixtures.

Corrosion Control Treatment

Water treatment corrosion control products that are phosphate based corrosion inhibitors are one of the main ways for lead prevention water treatment

About WatSim:
WatSim (Water Simulation) allows a water treatment chemist to evaluate the scale potential for common scalants over the range of water chemistry, temperature, and pH anticipated in a system.

WatSim was developed to allow a water treatment professional to readily evaluate the solubility of lead and copper, and scale potential for common scalants over the broadest of operating ranges without the necessity for tedious manual calculations  for the Langelier saturation index, Ryznar stability index, Puckorius equilibrium index, Larson’s Ratio, and C.C.P.P.

Even when all of these common indices are available conflicting results can cloud interpretation of what they are foretelling.  WatSim provides additional information in the form of sophisticated ion association model saturation levels.

WatSim allows a water treater to review popular, sophisticated, and some less known indicators relatively painlessly to develop a more complete picture of problems, and potential problems confronting a water treater.  A more precise solution can then be determined.
