Pipestone, Minn. – For the past four months, Lincoln Pipestone Rural Water (LPRW) in Pipestone, Minn. has been pilot testing a proprietary biological water treatment technology developed by California-based Carollo Engineers. The BIOTTTA process, which employs naturally occurring bacteria to eliminate nitrate contamination, has already delivered stellar results by eliminating all traces of nitrates during the pilot period.

Nitrates are the most widespread groundwater contaminant issue in the United States. Contamination is especially problematic in agricultural areas of the country, like southwest Minnesota. Previous widely implemented nitrate treatment methods generated difficult to dispose of waste streams, and were energy intensive, both contributing to high operational costs.

Demonstration testing began at the Holland Water Treatment Plant in March of this year. The process was officially introduced to community members and state regulators at an open house on Wednesday, August 21 as a potentially permanent solution to treating groundwater more efficiently and affordably. The Holland plant currently serves more than 4,000 residents.

“We were looking for an economical, eco-friendly solution that would keep us in compliance and protect our community,” said Mark Johnson, CEO, LPRW. “We needed a better option that would deliver the desired results while upholding our promise to deliver top quality water to our residents. BIOTTTA addresses each of these needs.”

BIOTTTA utilizes microorganisms to convert nitrates into harmless nitrogen gas, offering a cost-effective and more efficient alternative to other treatments that condense, rather than fully eliminate, nitrates in groundwater. The utilization of this unique biological process places LPRW ahead of the curve as rural water provider investing in cutting-edge technology to address a growing nitrate contamination problem among agricultural communities throughout the Midwest.

The pilot testing will continue until fully approved by the state to provide consistent results. LPRW intends to launch a full-scale system when that approval is received.
