With no electricity, some people are using car batteries for power.
"Every day, I visited at least three or four stores looking for bottled water, and I didn’t get any, so every night I try to do the math to be able to boil water and not use enough gas to be able to also cook," Ramírez said.
As the island struggles to recover, the impacts have hit the poor hard.
"Sampling of these wells done in 2015 indicated that some exceeded drinking water standards for volatile organic chemicals," Harris-Bishop said in an email.
Official government figures place the death toll from the storm at 48 in Puerto Rico.
"As more people are going hungry, FEMA keeps doing paperwork," said José Andrés, founder of non-profit food assistance organization World Central Kitchen. "When we should have less people hungry, it seems every day we have more.
Andrés said his group was providing 70,000 warm meals per day out of 6 kitchens across Puerto Rico without FEMA support as of Wednesday. The group hoped to expand to 100,000 meals by the end of the week but much more was needed for Puerto Rico’s 3.4 million people, Andrés said.
As the daily struggle for food and water persists, President Trump threatened to cut off federal support to the U.S. territory on Thursday.

SPRINGPORT, N.Y. — Some residents in Cayuga County are being asked to boil their water or use bottled water after a pipe malfunction Saturday, according to the health department.
Residents in the Springport Water District 1 — the Village of Union Springs and people living along Route 90 north and south of the village — are affected by the advisory.
The water system lost pressure during a water line repair, which could have allowed untreated water with harmful microbes to get into the drinking water, said Kathleen Cuddy, the county’s public health director.
The microbes can cause diarrhea, nausea, cramps, headaches or other symptoms that could be worse in children, older adults and people with poor immune systems, the department stated.
Health officials said people should allow water to boil for one minute before using it, and that boiled or bottled water should be used for cooking, drinking, making ice brushing teeth or washing dishes until further notice.
The Cayuga County Health Department will notify residents when the boil water advisory has been lifted, but said it could be in place for a few days while pipe repairs are finished and samples are done of the drinking water.

The Cayuga County Health Department on Saturday advised residents of the Village of Union Springs public water system and residents within the Town of Springport Water District Number 1 to boil their water after a loss of pressure due to a water line repair.
The advisory said that tap water should be brought to a rolling boil, boiled for one minute, and cooled before using. Another option would be using bottled water certified for sale by the state Department of Health. Boiled or bottled water should be used for drinking, making ice, washing dishes, brushing teeth, and preparing food until further notice.
The water system lost pressure due to a water line repair. When water mains lose pressure it increases the chance that untreated water and harmful microbes can enter your drinking water.
Harmful microbes in drinking water can cause diarrhea, cramps, nausea, headaches, or other symptoms and may pose a special health risk for infants, some elderly, and people with severely compromised immune systems. But these symptoms are not just caused by microbes in drinking water.
The health department said that once the repairs are completed, the Village of Union Springs and Town of Springport will take samples to confirm there is no contamination in the distribution system. It is anticipated that the Boil Water Order will remain in effect for a few days.

Dorado, Puerto Rico (CNN)Jose Luis Rodriguez waited in line Friday to fill plastic jugs in the back of his pickup truck with water for drinking, doing the dishes and bathing.
But there is something about this water Rodriguez didn’t know: It was being pumped to him by water authorities from a federally designated hazardous-waste site, CNN learned after reviewing Superfund documents and interviewing federal and local officials.
Friday afternoon, CNN watched workers from the Puerto Rican water utility, Autoridad de Acueductos y Alcantarillados, or AAA, distribute water from a well at the Dorado Groundwater Contamination Site, which was listed in 2016 as part of the federal Superfund program for hazardous waste cleanup.
In announcing the addition of the Dorado site to the Superfund program, the US Environmental Protection Agency says the area was polluted with industrial chemicals, including tetrachloroethylene and trichloroethylene, which "can have serious health impacts including damage to the liver and increasing the risk of cancer," according to the EPA.
It’s unclear whether there are public health risks from this particular well, however.
"While some of these wells are sometimes used to provide drinking water, the EPA is concerned that people could be drinking water that may be contaminated, depending on the well.
Autoridad de Acueductos y Alcantarillados, the water authority, was unaware that this well site was part of the Superfund program until CNN provided maps showing that this was the case, according to Luis Melendez, sub-director for environmental compliance at the utility.
In 2015, this well in Dorado, which is located near a shopping center, was found by the EPA to be safely within federal standards for PCE and chloroform, two industrial chemicals.
"I’ve never seen this before," he said, referring to the idea a Superfund site would be used as a source of public drinking water.
People waiting in line for water on Friday were largely unaware of these concerns.

A West Michigan shoe manufacturer is sending bottled water to East Rockford Middle School.
An old dumpsite for shoemaker Wolverine Worldwide is believed to be responsible for a chemical leak in the area that could pose health risks. That dumpsite is within a mile of the school.
About 800 students are drinking bottled water until groundwater test results come back.
David O’Donnell, who oversees remediation and redevelopment operations in West Michigan for the state’s Department of Environmental Quality, says the bottled water is only precautionary for the school.
“There is no information to suggest that there is groundwater contamination,” O’Donnell said.
According to O’Donnell, the school still felt it would be best not to drink any tap water until after the results come back.
“That was ultimately a decision the school made, in terms of safety, to have that bottled water,” he said.
O’Donnell says the test results for the school should be back by the end of the month.
Chris Hufnagel, Senior Vice President of Strategy at Wolverine Worldwide, said in a statement released today that the company is offering whole house filters to residents in the affected area who are getting their water tested.

She is living in a shelter and, along with 9,000 other people in the shelter, she needs water to drink.
Suppose the water was $5 per case at the time of the hurricane. This will be true of the other 9,000 people in the shelter as well.
It also means that more bottled water must be produced, since the demand for bottled water in other areas not hit by the hurricane will not be reduced.
Now, we could rely upon the good graces of those who own the bottled water companies to produce more bottled water at the same price as they were before the hurricane.
And as the price rises, those who value water less than your mother will reduce how much they demand, leaving your mother with the chance to buy the water she needs.
Trying to solve her problem with a price gouging law will result in most of the people in her shelter not getting water. The solution is instead to have people donate money to agencies that buy the water at $20 per case and give it to your mom.
Many corporations, aware of these economic realities, have taken the lead in relief efforts. More water will be available to people at the shelter using this approach than by limiting the availability of goods and services through price gouging laws.

ROCKFORD, MI — A Rockford middle school has shut off its drinking water and will be giving students and staff bottled water indefinitely after a former Wolverine World Wide tannery dump site was located near its water supply.
Superintendent Michael Shibler sent an email to East Rockford Middle School staff and parents Thursday after the district was notified by the Department of Environmental Quality, the Kent County Health Department and Wolverine World Wide of a former tannery dump site less than a mile northeast of the school.
Eight properties adjacent to the dump site are also being tested.
The Wolverine tannery in Rockford was demolished in 2010.
The property owner took samples from the property in 2011 and found evidence of metals, but did not locate any drums.
Tests on the water are being expedited.
The DEQ doesn’t know if sludge was dumped at the site.
Worrall said that there’s not yet evidence of groundwater contamination. However, he said the DEQ is "seeing a trend" with old Wolverine dump sites, and the groundwater is being tested "out of an abundance of caution."
Wolverine now says any homes testing above a federal health advisory level for the two PFAS – 70 parts-per-trillion (ppt) – will receive whole-house water filtration.

ROCKFORD, Mich. (WOOD) — Rockford Public Schools is shutting down drinking water fountains in one of its schools in light of recent tests revealing a toxic chemical in nearby wells.
In a letter sent to parents Thursday morning, Superintendent Michael Shibler said the district was disabling all drinking fountains in East Rockford Middle School “out of an abundance of caution.” Shibler said Wolverine Worldwide will be providing bottled water to students starting Thursday morning.
Shibler said the bottled water will also be used for cooking inside the school building until the district knows the status of its well water.
The dump site is separate from Wolverine Worldwide’s old House Street NE dump, where the company discarded sludge from its Rockford tannery until about 1970.
The Kent County Health Department is conducting its largest ever cancer cluster study around the House Street site and two other possible Wolverine dumps in the Rockford area.
It appears the contamination from the House Street dump is spreading to where the Rogue River flows into the Grand River.
He said he will notify parents as soon as the expedited test results are available, likely within two weeks.

UPDATE: Thousands of people are boiling water Wednesday after Polk County officials issued a boil water advisory.
The advisory started Tuesday after filtration problems and down water pumps shut down the water plant.
Officials with the McCaysville water service told Channel 3 the heavy amount of rain recently played a role in shutting the plant down.
Copperhill residents get their water from McCaysville.
However, they still have to boil it in order to drink it.
"Well we were hoping it was just one day,” The Copper Grill employee, Shelly Utley said, “But today’s day two, so it’s getting a little aggravating."
The city is going to have to haul water in from another location, due to the City of McCaysville water pumps being down and are experiencing filter issues. The City Clerk says they cannot pump any water from their system.

Water firm United Utilities has been fined £300,000 for contaminating supplies to more than 700,000 people.
Hundreds of thousands of residents in Lancashire had to boil their water in summer 2015 when microbial parasite cryptosporidium was found in the Franklaw water treatment works in Preston.
United Utilities Water Ltd spent £25 million as a result of the contamination, including £18.3 million in voluntary compensation payments to households and businesses, Preston Crown Court heard.
Concerned families panicked bough bottles of water from local supermarkets stripping their shelves bare.
However, it’s likely that in the minds of many customers there would have been ongoing concerns because confidence had been affected.’
‘I know from first-hand the inconvenience this incident caused, having lived in Lancashire for 40 years.
Richard Banwell, prosecuting for the Drinking Water Inspectorate, said temporary operational changes at the Franklaw plant led to contaminated water from an underground reservoir going back into the water treatment facility from July 27 to July 31 2015.
The warning for customers to boil their water was issued the next day and stayed in place until early September.
The court heard there was a ‘huge’ impact on the public.
He added: ‘No doubt the need to boil water was of significant inconvenience to everybody.’
