operation oaxaca: i think it’s this way.

target market - united states + mexico (018)

this is carlos.

checks are processing.

we got green light.

time to set the stage.

and get shit done.

i know where i wanna go with this project…

to the moon.

and mexico lol.

however, i’m a few thousand miles away from home.

so imma focus on the united states and its issues with heavy metals.

i will talk about their contamination problems, where the contamination occurs, and then…

i’ll decide what is the appropriate target market.

because economics first.

then technology.


usa, you got a problem.

and that problem is our water.

sure, here in la, we don’t have that many issues.

but what about those small villages and urban areas?

there could be bacteria, pfa’s, oil, heavy metals in their water.

and the help doesn’t seem to arrive.

here were some investigations done back in late 2021, where the guardian tested water samples from 120 sites across the united states.

all these sites contained either high levels of pfa’s or heavy metal ions.

pfa’s → chemical groups that makes products that resist heat, oil, stains, grease & water.

btw, all the samples from the 120 cities/villages came from water systems that serve >19 million people combined.

these were the results: (from the guardian)

“118 of 120 samples had concerning levels of pfa’s or arsenic above consumer report’s recommended maximum, or detectable amounts of lead.”

  • more than 35% of the samples had pfa’s, potentially toxic “forever chemicals”… at levels above consumer report’s recommended maximum.
  • about 8% of samples had arsenic, at levels above consumer report’s recommended maximum.
  • 118 of 120 samples had detectable levels of lead.

however… just because it was from one house… doesn’t mean the entire village has this problem.

maybe it was just a “unlucky pick” from the village.

the lead maximum amount for consumer report is zero.

the arsenic maximum is three parts per billion.

and pfa maximum is ten parts per trillion.

“parts per billion” → it means how much of the target molecule can exist per “x” amount of atoms/units.

but either way…

this is what’s coming out of the sink.

but where does it come from?

we must return to the source.

to the root.

let’s consider a few notions about what each metal does.

arsenic and mercury can exist naturally and find its way into acquifers, soil, and our treatment plants.

but lead has to be made.

and in some cases… that can be done via:

  • mining
  • textiles
  • pharmaceuticals
  • forestry

and i could go on.

but in the united states, the quesiton is…

where do we go?

and what direction?

if i’m being brutally honest…

it comes down to the conditions of the village/urban area.

if there’s mining, then that’s our answer.

if there’s arsenic underground, then that’s our answer.

if there’s a textile industry, then that’s our answer.

so the industry that i’m most likely to run after is the home appliances industry.

the consumer is the one that matters.

so most likely, i will make something like a kitchen filter that can filter out these ions (as these are the ones that will likely be there):

  • lead
  • arsenic
  • magnesium
  • calcium

other ions may exist, but that could be becaue there are mining operations going on.

for now, i want to make the solution as simple as possible…

so that anybody can make it from anywhere in the world.

i think all the pieces are there.

i just need to assemble them together for everyone to see.

other markets i am considering is the mining market, obviously.


  • heavy metal ions recovery (using mango peel filter)
  • emergency response filtration

but from thinking aboout economics…

the two markets i have narrowed it down to are:

  • heavy metal ions recovery from kitchen sinks (typically magnesium, calcium, arsenic & anything else that is caught)
  • heavy metal ions recovery from mining sludge/wastewater (typically lead, copper, aluminum, silver, gold, and more)

these have potential streams of revenue.

“money in” is the focus and how to turn a deep-tech product into a company that can make genuine impact.

tomorrow, the market research for both of these industries.

for now, i got a lab space to git & claim.
