Texans sound off against Elon Musk's 'horrifying' plans for dumping The Boring Company wastewater into Colorado River

• The Boring Company is facing criticism from Texans over its plans to dump treated wastewater.

• The company applied for a permit to dump 142,500 gallons per day last year.

• One resident said about 400 people showed up at the public meeting on The Boring Company's plans.

Elon Musk's tunnel-building venture, The Boring Company, is facing blowback from Texans who are speaking out against its plans to dump treated wastewater into the local water supply.

The Boring Company applied for a state permit last year under an affiliate name, Gapped Bass LLC, to dispose of about 142,500 gallons of treated wastewater per day from its facility in Bastrop, Texas into the Colorado River. Earlier that year, the Texas Commission on Environmental Quality said it had opened investigations into The Boring Company after receiving three complaints regarding the Bastrop site's handling of wastewater and concrete production.

On Tuesday night, several local Bastrop residents gathered at a meeting with TCEQ and The Boring Company to give public comment on the company's wastewater disposal permit after local citizen Chap Ambrose launched a campaign to "Keep Bastrop Boring." 

Ambrose told Insider ahead of the public meeting that while he's always considered himself a fan of Musk, he feels The Boring Company is breaking the law.

"I'm very invested here, my family lives here, and I have environmental concerns on what I see," Ambrose said.

He said in a post on Twitter that about 400 people showed up to attend the public meeting on Tuesday night. An estimated half of the people that came out to the meeting were turned away at the door due to capacity constraints, he said.

"The thought of this happening is horrifying," Erin, who runs an organic farm near the Boring Company facility, told Fox News. "This stuff — and we don't even know what it is — going into the river that we depend on for food production."

Ambrose told the publication he has concerns about Musk's propensity to "value speed over everything."
