Narrative:

I was working controller in charge combined with local control. I had 3 fixed wing cessnas and 2 helicopters. One cessna was a full stop and I just picked up the third cessna; a student solo on first solo in the pattern; aircraft Y. I was somewhat distracted due to being tasked with a random alcohol testing. The phone was ringing almost non-stop with calls from the air traffic manager; union rep; maintenance control coordinating for equipment outages.I had issued aircraft Y a sequence and clearance to follow and pilot read back correctly all instructions. I turned my back to answer a call and as I hung up the other local controller stated 'overshoot'. I immediately turned to see that my cessna cleared for runway 31R was on approximately 1/4 mile final for runway 31L and a business jet; aircraft X was right behind him. I immediately issued a go around for aircraft Y; but as I was doing that aircraft X pilot stated 'there is a cessna in front of us' and stated he was initiating a go-around. I immediately told aircraft Y to stop his climb; that there was a jet behind him climbing out over the top; and to remain low. I stated 'stay low; stay low; stay low.' aircraft Y complied and the local controller told aircraft X to go around to the left and got instructions from portland approach. After recovering; I told aircraft Y to fly right traffic and told him he had lined up on the wrong runway. I then made all aircraft under my control full stop. Shortly thereafter; I was relieved on local 2.we have recently had multiple issued with aircraft lining up on the wrong runway; overshooting final or drifting off the departure end into the parallel runway. I am unsure at this point about my recommendation; but do think something needs to be done. Whether or not it's on the air traffic side or the flight school side or both will be determined.
