Case studies

Water Well Solutions was contracted to redevelop Greenville Wisconsin’s # 3 Municipal Well. They employed a combination of enhanced chemical cleaning, using Pantonite PM77and their HY-RIP well rehabilitation process to physically inject the PM77into the geological formation to enhance the effectiveness of the treatment. This unique combination of enhanced well redevelopment employing PM77 and the HY-RIP process shows the effectiveness of this treatment technology for the redevelopment of a heavily impacted, borehole constructed high yielding municipal well.

Panton McLeod – Americas supervised the tank cleaning of a 40,000 gallon, steel, ground level storage tank in Westfield, Iowa, conducted by Maguire Iron, Co. The tank cleaning with Pantonite PM88 was effective and efficient with minimal down-time. No interior scaffolding or ladders were necessary for the complete cleaning of this tank.

The use of a blend of Muriatic and Hydroxyacetic acids lost its effectiveness, prompting the Department to seek alternating redevelopment methods. Results of AquaFreed and Pantonite treatments show equal or better performance with Pantonite, at a reduced cost and impact to the physical infrastructure of the well.

Maher Services, Inc. of North Reading, Massachusetts was contracted to conduct in-situ redevelopment of a high yielding well in Chatham, MA, removing encrusted iron, manganese and biofilm from the well screen and adjacent gravel packed material, resulting in a 55% increase in specific capacity.

In Plymouth, WI, a tank with accumulated iron and manganese oxides was cleaned using Pantonite PM88. The process involved a power wash, enhanced chemical cleaning, and a final disinfection with Sodium Hypochlorite. Notably, Pantonite completed the entire project efficiently within one day, both on-time and under budget.

Benchtop study results of Pantonite and other chemicals. The study aimed to evaluate NSF 60 certified products for drinking water treatment using fouled Tri pack material from the Acton, Massachusetts Water District.

In Situ redevelopment is a method by which chemical redevelopment is undertaken without the removal of the well pump and other bore hole appurtenances. It is a viable method at redeveloping a well where down time and/or costs are of the essence and the need for additional water is paramount to get through the summer heavy pumping season. Using a unique combination of in Situ well redevelopment employing Pantonite PM77 and the Nitro Pulse process resulted in close to a 5 fold increase in specific capacity from the pre-redevelopment yield and an increase in pumping capacity of over 300%
