Who Is McMullen Water Systems

McMullen Water Systems is based in St. Helens, Oregon, the heart of Columbia County. Our business’ history reflects the work ethic and family values of the community we call home. McMullen is not a franchise, but instead founded by an Oregonian for Oregonians. Our honest, straight-forward, people first philosophy has been the defining hallmarks of our business for the past 38 years.

McMullen Water Systems was originally part of McMullen Drilling, a small business founded by Bud McMullen (Scott’s dad) in 1976. He worked in the well drilling business for 5 years before opening the doors to his own business. Bud’s business philosophy was simple: “Listen to your client. Do it right the first time. On time. And on budget.”

McMullen Water Systems is now moving into its third generation. Scott’s sons, Justin and Shawn, are now working for the company and are proudly carrying on the McMullen tradition of offering our clients the best products, at the best value, with the best service in the industry. That is the strength of our company, and the McMullen Way.

Regardless of your well drilling, water pump or water treatment needs, our goal today is the same as it was 38 years ago when Bud McMullen opened his doors; to earn your business and your trust. McMullen Water Systems is licensed, insured, and bonded. The company’s Construction Contractor’s Board (CCB) number is 185035.

FAQ

Wells are routinely tested for coliform bacteria, which come from soil or vegetation, and in the intestinal tract of warm-blooded animals (fecal coliform bacteria). The many sources of bacterial pollution include runoff from woodlands, pastures, and feedlots; septic tanks and sewage plants; and animals (wild or domestic). Most coliforms are harmless residents of soil and will not make people sick. Some strains of E. coli, the most common fecal coliform bacterium, may be pathogens. Some E.coli found in food have been lethal, so their presence should be taken very seriously. Testing for coliform bacteria is inexpensive and their presence indicate that harmful, pathogenic bacteria could possibly enter or exist in the well. So, if a well tests positive for coliform bacteria, follow-up testing for E.coli sometimes is recommended depending on the specific lab test results. Some coliform tests can provide results for both total coliform bacteria (the indicator) and E. coli, the sign of fecal contamination and potential pathogens.

A water well should be disinfected:

  1. After construction of the well and before the water is consumed. Water from a newly constructed well should test free of bacteria before the water is used.
  2. After an existing well is serviced. Any time a water well system is opened up, it creates the potential for bacteria to enter the well, so disinfection after servicing helps ensure the water is free of bacteria.
  3. If there is a visible defect in the well system that could enable bacteria to enter the well. Examples of such defects are a cracked or loose well cap, or damage to the well casing (the vertical pipe that extends above the surface of the ground).
  1. Check the breaker
  2. Check for a reset button under the well pump control box.
  3. Call for service.
