Part 2 of 4: How Heat Illness Progresses, and What to Do About It
Heat illness moves along much like a ladder, and every rung is a chance to intervene. It usually starts with heat cramps: painful muscle spasms, often in the legs or abdomen, caused by salt loss through sweat. Next comes heat exhaustion. Watch for heavy sweating, weakness, dizziness, headache, nausea, clammy skin, and a fast, weak pulse. A worker at this stage needs to stop, move to shade or air conditioning, loosen clothing, sip water, and cool down with wet cloths. Heat exhaustion handled promptly is a bad afternoon. Ignored, it can become heat stroke.
Heat stroke is a medical emergency, full stop. According to the OSHA Technical Manual, once heat stroke sets in, core body temperature can climb to 106 degrees Fahrenheit or higher within 10 to 15 minutes. Signs include confusion, slurred speech, loss of coordination, seizures, and loss of consciousness. Here is the field detail that trips people up: do not wait for dry skin. The textbook sign of heat stroke is that sweating stops, but OSHA and NIOSH both note that exertional heat stroke, the kind that hits people doing hard physical work, frequently presents with the worker still sweating heavily. If a crew member is confused or stumbling on a hot day, treat it as heat stroke regardless of how wet his shirt is.
The response: call 911 immediately, then cool the worker aggressively while you wait. Cold water immersion is the most effective first-line treatment. If you cannot immerse, soak the worker with cold water and place ice packs at the neck, armpits, and groin, where large blood vessels run close to the skin. One standard first aid caution: do not give fluids to anyone who is not fully alert, because of the choking risk.
Every crew should know this ladder cold. Tomorrow: the hydration numbers that keep people off it in the first place.
Key Takeaways
• The progression is cramps, then exhaustion, then stroke. Intervene early and it stays minor.
• Heat stroke can push core temperature to 106 degrees within 10 to 15 minutes. Confusion on a hot day means call 911, even if the worker is still sweating.
• Cool first, cool fast: cold water immersion or ice at the neck, armpits, and groin. No fluids unless fully alert.

Industry Update
EPA Just Removed a $200,000 Barrier for Small Water Systems
If you drill, service, or supply small municipal and rural water systems, this one is worth passing along to your customers. EPA announced late last month that it is waiving the fees for small communities applying for Water Infrastructure Finance and Innovation Act (WIFIA) loans in fiscal years 2026 and 2027. The waivers cover the $25,000 application fee for communities with populations of 25,000 or fewer, plus the credit processing fee, which currently averages about $156,000 per loan. Combined, that is nearly $200,000 in upfront costs that will no longer stand between a small system and federal financing.
The program has real money behind it: roughly $11 billion in available financing, and for small and rural communities WIFIA can cover up to 80 percent of eligible project costs. The eligible project list reads like a driller's work order: aquifer recharge, alternative water supply, brackish and seawater desalination, and drought prevention and mitigation projects all qualify, alongside conventional drinking water infrastructure. EPA is accepting letters of interest now.
The practical angle: those upfront fees have historically kept exactly the kind of small utilities most of our readers work for from applying at all. A contractor who mentions this waiver to a water board weighing a new well field, a replacement well, or a recharge project this year is bringing them real money. The waivers run through fiscal year 2027, subject to program requirements and available administrative funds, so the window is defined.

Part 2 of 4: Natural Pack or Filter Pack
Yesterday's sieve analysis is now in hand, and the first decision is what completion type is appropriate. In a naturally developed well, you select a slot that lets the fines pass during development and leaves the coarse fraction of the formation itself packed against the screen. In a more common filter packed well, you replace the zone around the screen with a graded sand, gravel, or glass bead pack, and size the slot to the pack instead of the formation.
Coarse, well-graded alluvium with a healthy uniformity coefficient is a natural development candidate, and a properly developed natural well is hard to beat for cost and simplicity. The literature is consistent on when to reach for a filter pack instead. Filter packing is appropriate when the formation is fine grained and highly uniform, or where no slot small enough to hold the formation would still pass water (or drilling fluid). Filter pack is also necessary in highly laminated formations, where sand, silt, and clay alternate in thin beds and you cannot pinpoint layer boundaries well enough to place slots precisely. Filter packs are also the better approach in poorly cemented sandstone, where the formation itself will not stay put. Those three conditions cover most of the filter pack decisions you will make.
The pack's real advantage is control. A natural completion asks the formation to be its own filter, and the formation is whatever the hole gives you. A filter pack replaces that variable with an engineered material of known gradation and uniformity, which means the slot math you will see tomorrow keys to a material you chose, not one you inherited. Get the pack right and the rest of the design follows.
One more point worth knowing: A100-20 does not try to be a design textbook. It points designers to the standard references, including the Roscoe Moss Handbook of Ground Water Development, Groundwater and Wells, and the EPA Manual of Water Well Construction Practices. If those three are not on your shelf or your engineer's, that is worth fixing.
What to consider on your next bid
If the sieve curves show fine, uniform, or laminated material, bid the filter pack up front. Retrofitting sand control into a naturally completed well is far more expensive than packing it right the first time.
Treat the pack as an engineered material, not a commodity. The gradation certificate is the spec, and this week's remaining parts give you the numbers to hold it to.
