breathing, harsh in the enclosed environment of a level-A protective suit, came over the station’s speakers. “Don’t lose your marbles.”I grinned under my mask—despite the smell, despite the danger, everything. There was never any way to tell who would panic in an emergency. “I wasn’t.”
“Hold on.” Some noises. “Kinnis and Cel now have their gear. I’m on my way. Tell me what’s happening.”
I briefed her on the PCE; it was the metabolites—the vinyl chloride and dichloroethylene—that would be most dangerous. “But the weakened bugs mean the system is unreliable. There are a score of things that could—”
The door opened: Magyar, huge and clumsy in her silver flash-coated moon suit, lugging a large case. “Your suit.”
It was strange to see her in front of me but hear her voice from behind. I took the case, put it on the floor, snapped it open, lifted out the equipment. The tank and two-stage regulators were heavy. I swung them out upright on the floor, then squatted to check the tanks and valves. I turned on the air, felt it cool and steady against my palm. A quick glance at my minitank. Reading empty. I slung the harness of built-in air hoses over my shoulder, then ripped off my EEBA and fitted the larger, silicon face piece over nose, mouth, and jaw. The air was cool and slightly metallic. The face piece fitted tight and clean. I chinned on the radio. “Keep your eyes on the vinyl chloride while I get into this thing.” I stepped in the heavy neoprene boots and pulled the suit up to my waist. The bat-winged upper half was awkward, but I managed. Hood next. It cut my peripheral vision a bit.
Magyar studied the board and flipped a switch, then pushed a button. The noise and flashing red lights stopped abruptly.
Cel and Kinnis came in. “What happened?” Kinnis asked, at the same time as Cel said, “Tell us what to do.” They both looked uncertainly from Magyar to me and back again.
“For now, we all do as Bird says. Except when I disagree. Kinnis, help her on with that thing.”
I was already done, just checking that all the zips were
fastened. Everything felt very unreal. I couldn’t make out Kinnis’s expression from behind two layers of metallicized PVC, but he moved tightly, tensely.
“I asked you both to stay because I trust you, and Magyar and I may need your help. In the present concentrations you should be safe enough with SCBAs and skinnies—but give each other a quick visual check for tears or weak spots in your suits. If conditions change, I’ll ask you to leave.” They both nodded. “Here’s the situation. Somewhere up-line there’s been a massive spill of PCE. It got into our pipes. It’s killed everything in the troughs. Right now, everything’s being pumped back out into the holding tanks. Influent has been diverted to other plants, but we’re monitoring it. As soon as it runs clear, we can take it again.”
“Only if the troughs have been cleaned,” Cel said.
“That’s your job. And Kinnis’s. Even if you get only three or four back up, it’ll keep the system moving. First, a warning. PCE is toxic, in liquid and vapor form. First signs are dizziness and nausea. Either of you two feel dizzy, leave immediately. The gas will irritate your eyes and burn your skin. Check your masks carefully for a tight seal. Do that by turning off your air for three seconds and trying to draw a breath. If you can, you’re leaking. Do it now, before the fumes get bad. When the fumes get concentrated enough—though they shouldn’t, especially where you’ll be—you could suffocate without your respirators. So don’t remove them for any reason whatsoever. Once the bugs start to metabolize the PCE there’ll be vinyl chloride and dichloroethylene.” I hesitated, then decided there was no such thing as too much information. And I didn’t know exactly how much Magyar did or didn’t know. “Vinyl chloride and dichloroethylene are much meaner than PCE. Carcinogenic, recalcitrant, and very flammable with a low flash point. Neither of you have flash suits. Once the concentration of those chlorinated aliphatics reaches a certain point, you leave. Got that? Good. Now, either of you know how to program by remote?”They both nodded. Kinnis remembered his radio. “Yes.”
“Kinnis, you stay here and reprogram the rakes for removal of reeds. Cel, I want you to start hosing down the troughs. The two of you will coordinate pumping out the tainted swill.” The members
