Let’s examine what was said.
Immediately starting with a premise, “… fracking isn’t the culprit in contaminated groundwater near natural gas wells. Poor well construction is.”
Then, the answer of how to correct poor construction is given – not complete but rendered as if a ‘solve all’.
This is a fallacy of assumption that the premise is correct, not proven correct, but assumed.
Then the writer(s) contend fracking is not flawed and a threat to water. They go on to recite where and when fracking has been used and some changing expert views.

It is not a simple yes or no involved here.

Poor well construction does indeed put contamination in the water. But so does the fracking. Look at each in turn.
a. Poor well construction.
The ‘culprit’ here is generally the annulus or space between gas pipe and drilled hole. Hydro carbons here migrate from well plug up to last casing or beyond. If the drilling went through a fault, it will follow the fault also. The genie is out of the bottle.
If the well plug is faulty, then the frack zone leaks hydrocarbons into the annulus, including frack fluids and ‘production’ water besides the hydrocarbons. The fracking process can cause this breech just like it breaks the rock. This cement plug can also shrink or just be sufficient for test pressure and then blow under frack pressure.
This should read in high Bradenhead pressures and be an indicator and companies are supposed to report this, but as you can see if a fault is bleeding off the contamination, the pressure won’t show.
b. Fracking (and yes, it is flawed).
The culprit in this case is generally is the fracking intersects faults and/or formation anomalies. Sometimes, as the attempt is made to maximize yields, fracking extends upper ‘so called’ seal formations. This more common in shallow wells ( and they are at all kinds of depths – not just thousands of feet as claimed) and fracks go vertical because of sufficient overburden pressure. They can also penetrate an “over” formation because it is slanting to one side or other of the well bore. These formations may be salt water “basements” of potable water above and an aquifer because of porosity.
The frack may just penetrate a nearby fault.
In the Divide Creek Seep, it appears both a. and b. occurred.  After all remediation of a faulty plug, the seep was only reduced to about 50%. Unknown hydrocarbons also surfaced, but agencies would not test them according to an observer. On the Pavillion EPA study, it appeared a. and b. occurred with contamination of ‘basement’ waters leading the hydrocarbons floating to the potable waters. The indicator here was the presence of frack unique fluids.

Besides the faulty assumption to a conclusion shifting guilt to ‘one over the other’, they are both present. Truly, two wrongs don’t make a right!

Note: Chevron does ‘top to bottom’ cementing as practice.
