Poison Water
9pm, BBC Two
“Before I die, I want this truth to come out.” Carol Wyatt was a victim of what this damning film claims to be the biggest mass poisoning in British history – the 1988 water contamination in north Cornwall. She recalls her water being the colour of loo cleaner. Many complaints were made (“Our daughter’s hair has turned green and it’s sticking like glue,” says one phone recording) but the authorities – some speak here, including South West Water authority’s former head of operations – insisted the water was safe. Despite claims that the aluminium caused Alzheimer’s, there has not been a fully independent public inquiry. Perhaps this can change that. Hollie Richardson
Grand Designs: House of the Year
8pm, Channel 4
From a Caribbean-inspired home that bursts with colour to a roofline that frames views of cathedral spires and meadows, this week’s six houses are properties that “channel vacation vibes”. Kevin McCloud and his team nosy around before choosing which ones will make it on to the shortlist. HR
Shetland
9pm, BBC One
The rural crime investigations continue, as Shetland’s 10th season enters its final stretch. Tosh and Calder’s attempt to find the murderer rumbles on, amid attacks, accusations of corrupt coppers and a pair of sisters who’d prefer not to have their bonding time interrupted by knocks on the door from the fuzz. Who would, eh? Alexi Duggins
The Hunting Party
9pm, U&Alibi
Arlo Brandt is this week’s serial killer on the loose in the slightly ludicrous but undeniably entertaining crime drama set after a prison explosion and breakout. Arlo usually likes to kill with items bought from a shopping channel – but he now has a new approach, as Bex (Melissa Roxburgh) and her team try to catch him. HR
Doc
9pm, Sky Witness
Season two of a shamelessly soapy medical drama starts with Molly Parker’s Minneapolis medic Amy Larsen torn between two colleagues: her new boyfriend, and the ex-husband she can’t remember divorcing due to traumatic memory loss. Never mind all that, though: one of the team has been shot! Jack Seale
Emergency Helicopter Medics
10pm, Channel 4
A teenager has a brain injury in this episode of the paean to the heroics of airborne medics. He is raced through the skies to hospital after a car collision in Hemel Hempstead, while other patients include a Bicester resident who needs their heart shocking back to a normal rhythm. AD
Film choice
C’mon C’mon (Mike Mills, 2021), 2am, Channel 4
A film that slowly digs its emotional claws into you, Mike Mills’s tender black-and-white drama is blessed with terrific performances from Joaquin Phoenix as radio producer Johnny and Woody Norman as his young nephew Jesse. They are thrown together when Jesse’s mum, Viv (the ever empathetic Gaby Hoffmann), has to leave suddenly to look after his bipolar dad. There’s a lot of humour to be mined in the imaginative nine-year-old’s direct line in questioning, while Johnny uses his mic as a private diary to ponder his inadequate parental skills and strained relationship with his sister.
